Every little ring: Another look at excessive smartphone use

Last week I did seven back-to-back BBC radio interviews concerning my thoughts on a new study on smartphone use carried out by Opinium Research for Virgin Mobile and reported in a number of papers including the Daily Mail. The company surveyed 2,004 British adults (aged 18 years and over) who own a smartphone as well 200 British teenagers and tweenagers aged between 10 and 17 years. The main findings were that:

  • British adults receive an average of 33,800 mobile phone messages and alerts annually
  • British adults spend the equivalent of 22 days a year checking messages on their smartphones (an average of 26 minutes a day)
  • An average smartphone user gets 93 buzzes a day
  • Those aged between 18 and 24 years have almost three times more messages receiving 239 messages and alerts a day on average (approximately 87,300 a year).
  • On average, Britons are members of six chat groups, although a small minority (2%) are members of 50 groups or more, rising to 7% among those aged 18 to 24 years.
  • One in four adults say they check a WhatsApp message instantly, with this increasing to almost one in three among 18 to 24-year-olds.
  • Smartphone users receive 427% more messages and notifications than they did a decade ago
  • Smartphone users sent 278% more messages than they did a decade ago

The survey found a contributing factor behind the surge in the number of messages received was the rise of group chats on platforms like WhatsApp and Facebook. In the press release, Dr Dimitrios Tsivrikos (consumer and business psychologist at University College London) said:

“The boom in smartphone use was a positive trend and allowed consumers greater control over their lives. In an age where we are constantly surrounded by endless tasks, always flooded with a sea of data, smartphones allow us to manage our lives in a way that suits us. From calendars and reminders, to emails and instantaneous access to an encyclopaedia of human knowledge, smartphones give us total control, right at our fingertips.”


There was nothing in the study that I found particularly surprising but I was hoping to see what survey had found from those under 18 years of age (but nothing was reported in the national newspapers and I’ve been unable to track down anything beyond the press release).

In my radio interviews, most of the presenters wanted to know the extent to which individuals are now ‘addicted’ to their mobile phones. I then trotted out my usual response that ‘people are no more addicted to their smartphones than alcoholics are addicted to a bottle’ and said if there was anything addicting then it was the application (e.g., gaming, gambling, shopping, social networking, etc.) rather than the smartphone itself. I also went through the addiction components model and hypothesized what the behaviour of a smartphone addict would look like if they were genuinely addicted to their smartphone applications:

  • Salience – This occurs when using a smartphone becomes the single most important activity in the person’s life and dominates their thinking (preoccupations and cognitive distortions), feelings (cravings) and behaviour (deterioration of socialised behaviour). For instance, even if the person is not actually on their smartphone they will be constantly thinking about the next time that they will be (i.e., a total preoccupation with smartphone use).
  • Mood modification – This refers to the subjective experiences that people report as a consequence of using their smartphone and can be seen as a coping strategy (i.e., they experience an arousing ‘buzz’ or a ‘high’ or paradoxically a tranquilizing feel of ‘escape’ or ‘numbing’ whenever they use their smartphone).
  • Tolerance – This is the process whereby increasing amounts of time on a smartphone are required to achieve the former mood modifying effects. This basically means that for someone engaged on a smartphone, they gradually build up the amount of the time they spend using a smartphone every day.
  • Withdrawal symptoms – These are the unpleasant feeling states and/or physical effects (e.g., the shakes, moodiness, irritability, etc.), that occur when the person is unable to access their smartphone because they have mislaid or lost it, are too ill to use it, in a place with no reception, etc.
  • Conflict – This refers to the conflicts between the person and those around them (interpersonal conflict), conflicts with other activities (social life, hobbies and interests) or from within the individual themselves (intra-psychic conflict and/or subjective feelings of loss of control) that are concerned with spending too much time on a smartphone.
  • Relapse – This is the tendency for repeated reversions to earlier patterns of excessive smartphone use to recur and for even the most extreme patterns typical of the height of excessive smartphone use to be quickly restored after periods of control.

Using these criteria, I then went on to say that very few people would be classed as addicted to their smartphones. However, I did point out that such behaviour is on a continuum and that there may be a growing number of people that experience problematic smartphone use rather than being addicted. The examples I used included those individuals who would rather spend time on their smartphone than spending it with their partner and/or children, or individuals who spend so much time on their smartphone that it impacts on their job or their education (depending upon how old they are). Neither of these on their own (or together) necessarily indicate addictive use of smartphones but could be a sign that such individuals are at risk for developing an addiction to the applications on their smartphone. However, I would still argue that someone that spends all their time on social networking sites and social media (via their mobile phone) are a social media addict rather than a smartphone addict although others might see this as a semantic difference rather than a difference of substance. Whatever we call the behaviour, there does seem to be growing evidence that smartphones play a major role in people’s lives and that a small minority appear to have problematic use (as outlined in a number of studies that I have co-authored – see ‘Further reading’ below).

Eyes on the prize: Is the buying of loot boxes in videogames a form of gambling?

The buying of loot boxes takes place within online videogames and are (in essence) virtual games of chance. Players use real money to buy virtual in-game items and can redeem such items by buying keys to open the boxes where they receive a chance selection of further virtual items. Other types of equivalent in-game virtual assets that can be bought include crates, cases, chests, bundles, and card packs. The virtual items that can be ‘won’ can comprise basic customization (i.e., cosmetic) options for a player’s in-game character (avatar) to in-game assets that can help players progress more effectively in the game (e.g., gameplay improvement items such as weapons, armor). All players hope that they can win ‘rare’ items and are often encouraged to spend more money to do so because the chances of winning such items are minimal. Many popular videogames now feature loot boxes (or equivalents) including Overwatch, Middle-earth: Shadow of War, Star Wars Battlefront 2, FIFA Ultimate Team, Mass Effect: Andromeda, Fortress 2, Injustice 2, Lawbreakers, Forza Motorsport 7, and For Honor. In short, all of these require the paying of real money in exchange for a completely random in-game item. In an interview with Eurogamer, psychologist Jamie Madigan said:

“Whenever you open [a loot box], you may get something awesome (or you may get trash). This randomness taps into some of the very fundamental ways our brains work when trying to predict whether or not a good thing will happen. We are particularly excited by unexpected pleasures like a patch of wild berries or an epic skin for our character. This is because our brains are trying to pay attention to and trying to figure out such awesome rewards. But unlike in the real world, these rewards can be completely random (or close enough not to matter) and we can’t predict randomness. But the reward system in your brain doesn’t know that. Buying [loot boxes] puts them into the same category of packs of Pokémon cards or baseball cards. Unlike gambling in a casino, you’re going to get something out of that pack. Maybe just not the thing you wanted”.


Although there are many definitions in many disciplines defining gambling, there are a number of common elements that occur in the majority of gambling instances that distinguish ‘true’ gambling from mere risk-taking. These include: (i) the exchange is determined by a future event, which at the time of staking money (or something of financial value) the outcome is unknown, (ii) the result is determined (at least partly or wholly) by chance, (iii) the re-allocation of wealth (i.e., the exchange of money [or something of financial value] usually without the introduction of productive work on either side, and (iv) losses incurred can be avoided by simply not taking part in the activity in the first place. Added to this it could be argued that the money or prize to be won should be of greater financial value than the money staked in the first place. Based on these elements, the buying of loot boxes (or equivalents) would be classed as a form of gambling, as would other activities such as the Treasure Hunter and Squeal of Fortune games within the Runescape videogame and online penny auctions (which I have argued in previous papers – see ‘Further reading’).

In the UK Gambling Commission’s most recent (March 2017) position paper on virtual currencies and social casino gambling noted:

“One commonly used method for players to acquire in-game items is through the purchase of keys from the games publisher to unlock ‘crates’, ‘cases’ or ‘bundles’ which contain an unknown quantity and value of in-game items as a prize. The payment of a stake (key) for the opportunity to win a prize (in-game items) determined (or presented as determined) at random bears a close resemblance, for instance, to the playing of a gaming machine. Where there are readily accessible opportunities to cash in or exchange those awarded in-game items for money or money’s worth those elements of the game are likely to be considered licensable gambling activities [Section 3.17]…Additional consumer protection in the form of gambling regulation, is required in circumstances where players are being incentivised to participate in gambling style activities through the provision of prizes of money or money’s worth. Where prizes are successfully restricted for use solely within the game, such in-game features would not be licensable gambling, notwithstanding the elements of expenditure and chance [Section 3.18]”.

Consequently, the UK Gambling Commission does not consider loot boxes as a form of gambling because (they claim) the in-game items have no real-life value outside of the game. However, this is not the case because there are many websites that allow players to trade in-game items and/or virtual currency for real money. The Gambling Commission appear to acknowledge this point and claim that the buying of in-game loot boxes (and their equivalents) are not gambling but if third party sites become involved (by allowing the buying and selling of in-game items), the activity does become a form of gambling. As Vic Hood (in a 2017 article in Eurogamer) rightly notes, this appears to be a case of the law struggling to keep pace with technology. There are also issues surrounding age limits and whether games that offer loot boxes (or equivalents) should be restricted to those over the age of 18 years.

Predictably, those in the videogame industry do not view the buying of loot boxes as gambling either. For instance, Dirk Bosmans (from PEGI [Pan European Game Information], the European-based videogame rating organization) stated in a recent interview with Eurogamer that:

“Loot crates are currently not considered gambling: you always get something when you purchase them, even if it’s not what you hoped for. For that reason, a loot crate system does not trigger the gambling content descriptor. If something is considered gambling, it needs to follow a very specific set of legislation, which has all kinds of practical consequences for the company that runs it. Therefore, the games that get a PEGI gambling content descriptor either contain content that simulates what is considered gambling or they contain actual gambling with cash payouts. If PEGI would label something as gambling while it is not considered as such from a legal point of view, it would mostly create confusion. We are always monitoring such developments and mapping consumer complaints. We see a growing need for information about specific features in games and apps (social interaction, data sharing, digital purchases), but the challenge is that such features are rapidly becoming ubiquitous in the market, yet they still come in very different shapes and sizes.”

This appears somewhat hardline given that PEGI’s descriptor of gambling content is used whenever any videogame “teaches or encourages” gambling. Such a descriptor would arguably cover gambling-like games or activities and the buying of loot boxes is ‘gambling-like’ at the very least. The same stance has been taken by the Entertainment Software Rating Board (ESRB) which rates videogames in Canada and the USA. A spokesman for the ESRB told Eurogamer that:

“ESRB does not consider [the buying of loot boxes] to be gambling because the player uses real money to pay for and obtain in-game content. The player is always guaranteed to receive something – even if the player doesn’t want what is received. Think of it like opening a pack of collectible cards: sometimes you’ll get a brand new, rare card, but other times you’ll get a pack full of cards you already have. That said, ESRB does disclose gambling content should it be present in a game via one of two content descriptors: Simulated Gambling (player can gamble without betting or wagering real cash or currency) and Real Gambling (player can gamble, including betting or wagering real cash or currency). Neither of these apply to loot boxes and similar mechanics.”

At present, there are a number of countries (mainly in South East Asia such as China and Japan) who do view the buying of loot boxes as a form of gambling and have incorporated such activities into their gambling regulation. However, most countries have either not considered regulating the buying of loot boxes at all, or (like the UK) have ruled out that buying loot boxes does not currently meet their regulatory definition of gambling. Although there has been little published in academic journals on loot boxes, a number of articles in the trade press have claimed that the buying of loot boxes can be problematic and/or addictive because they are designed using highly similar reward schedules to those used in the design of slot machines. This is something that have also pointed out in relation to similar activities to the buying of loot boxes where individuals play for points rather than money. Personally, I view the buying of loot boxes as a form of gambling particularly because the ‘prizes’ won are (in financial terms) often a lot less than that of the price paid. Obviously I am out of step in relation to the regulators in my own country, but if third party websites continue to host services where in-game virtual items can be bought and sold, the activity definitely constitutes a form of gambling by almost any definition of gambling currently used in the field of social sciences.

To see or not to see: A brief look at hallucinations in virtual reality applications

As a teenager I was fascinated with LSD purely as a consequence of my love of The Beatles and its alleged association with songs such as ‘Lucy in the Sky with Diamonds‘ (I say ‘alleged’ because all Beatle fanatics know that this song got its’ title from a drawing by John Lennon’s son Julian and that lyrically the song was inspired by the writings of Lewis Carroll, the creator of Alice in Wonderland [AIW], a book which gave its’ name to AIW Syndrome that I examined in a couple of previous blogs).

When I first started teaching my ‘Addictive Behaviours’ module back in 1990, almost all my lectures concentrated on drug addictions (as opposed to behavioural addictions which now take centre stage in my teaching), and it was my session on hallucinogenic drugs (also known as psychedelic drugs) that was always the most fun to teach and the topic that students appeared to be most engaged in. Like many of my students, I have always been interested in altered states of consciousness both in my own research into addiction and the topic more generally.


The reason why I mention all these things as that I did a media interview on the hallucinogenic effects of virtual reality products. The interview was based on comments by Microsoft researcher Mar Gonzalez Franco, who said that virtual reality will soon replace the need for hallucinogenic drugs. More specifically, she was quoted as saying:

“By 2027 we will have ubiquitous virtual reality systems that will provide such rich multi-sensorial experiences that will be capable of producing hallucinations which blend or alter perceived reality. Using this technology, humans will retrain, recalibrate and improve their perceptual systems…In contrast to current virtual reality systems that only stimulate visual and auditory senses, in the future the experience will expand to other sensory modalities including tactile with haptic devices“.

Claims that VR products have the potential to induce hallucinogenic experiences have already started appearing in the media. A recent story in the Daily Mail reported that there was already a VR app (SelfSound) that claimed it can reproduce the effects of hallucinogenic drugs and plays on the neurological phenomena known as synaesthesia and that a “program is used to promote mediation through creating abstract reality [and] plays face-melting music with synesthetic DMT-style visualizations uniquely generated in response to [a person’s] voice”. (DMT is an abbreviation for dimethyltryptamine, a powerful hallucinogenic drug).

Over the last seven years, I have published a series of studies with Dr. Angelica Ortiz de Gotari (some of them listed in the ‘Further reading’ section below) showing that hallucinations are common among video gamers in our working examining Game Transfer Phenomena (GTP). Therefore, it’s no surprise that VR games can do the same thing. We have reported that visual and auditory hallucinations are commonly experiences by regular videogame players.

For instance, one of our studies published in the International Journal of Human-Computer Interaction found that some video gamers experience altered visual perceptions after playing (e.g., distorted versions of real world surroundings). Others saw video game images and misinterpreted real life objects after they had stopped playing. Gamers reported seeing video game menus popping up in front their eyes when they were in a conversation, or saw coloured images and ‘heads up’ displays when driving on the motorway. Our study analysed 656 experiences from 483 gamers collected in 54 online video game forums. Visual illusions can easily trick the brain, and staring at visual stimuli can cause ‘after-images’ or ‘ghost images’ among videogame players. We found that GTP were triggered by associations between video game experiences, and objects and activities in real life contexts. Our findings also raised questions about the effects of the exposure to specific visual effects used in video games.

We also reported that in some playing experiences, video game images appeared without awareness and control of the gamers, and in some cases, the images were uncomfortable, especially when gamers could not sleep or concentrate on something else. These experiences also resulted in irrational thoughts such as gamers questioning their own mental health, getting embarrassed or performing impulsive behaviours in social contexts. However, other gamers clearly thought that these experiences were fun and some even tried to induce them.

Visual experiences identified in GTP show us the interplay of physiological, perceptual and cognitive mechanisms and the potential of learning with video games even without awareness. It also invites us to reflect about the effects of prolonged exposure to synthetic stimuli and the challenges that the human mind affront due to the technological advances that are still to come. However, because we collected our data for most of our published studies from online video game forums, the psychological profile of the gamers in our studies are unknown. However, different gamers reported similar experiences in the same games. This highlights the relevance of the video games’ structural characteristics but gamers’ habits also appear to be crucial. Some gamers may be more susceptible than others to experience GTP. The effects of these experiences appear to be short-lived, but some gamers experience them recurrently. It goes without saying (but I’ll say it anyway) that more research is needed to understand the cognitive and psychological implications of GTP. Most of these GTP experiences are viewed positively but a small minority of players find them detrimental.

Whether such hallucinations – either in typical videogames or VR videogames – can be induced on demand is debatable. Very few players in our own research said they were able to induce hallucinations. At present, we simply don’t know what the long-term effects of VR gaming will be and that goes for VR-induced gaming hallucinations too. It may be the case that VR induced hallucinogenic states will be ‘safer’ than ones induced by psychedelic drugs as there is no ingestion of a psychoactive substance, but that’s just speculation on my part.

Screenage rampage: What should parents know about videogame playing for children?

Last month, the World Health Organisation (WHO) announced that it was planning to include ‘Gaming Disorder’ (GD) in the latest edition of the International Classification of Diseases. This followed the American Psychiatric Association’s decision to include ‘Internet Gaming Disorder’ in the latest edition of the Diagnostic and Statistical Manual of Mental Disorders in 2013. According to the WHO, an individual with GD is a person who lets playing video games “take precedence over other life interests and daily activities,” resulting in “negative consequences” such as “significant impairment in personal, family, social, educational, occupational or other important areas of functioning.”

I have been researching videogame addiction for nearly 30 years, and during that time I have received many letters, emails, and telephone calls from parents wanting advice concerning videogames. Typical examples include ‘Is my child playing too much?’, ‘Will playing videogames spoil my pupils’ education?’, ‘Are videogames bad for children’s health? and ‘How do I know if a child is spending too long playing videogames?’ To answer these and other questions in a simple and helpful way, I have written this article as a way of disseminating this information quickly and easily.


To begin with parents should begin by finding out what videogames their children are actually playing! Parents might find that some of them contain material that they would prefer them not to be having exposure to. If they have objections to the content of the games they should facilitate discussion with children about this, and if appropriate, have a few rules. A few aims with children should be:

  • To help them choose suitable games which are still fun
  • To talk with them about the content of the games so that they understand the difference between make-believe and reality
  • To discourage solitary game playing
  • To guard against obsessive playing
  • To follow recommendations on the possible risks outlined by videogame manufacturers
  • To ensure that they have plenty of other activities to pursue in their free time besides the playing of videogames

Parents need to remember that in the right context videogames can be educational (helping children to think and learn more quickly), can help raise a child’s self-esteem, and can increase the speed of their reaction times. Parents can also use videogames as a starting point for other activities like painting, drawing, acting or storytelling. All of these things will help a child at school. It needs to be remembered that videogame playing is just one of many activities that a child can do alongside sporting activities, school clubs, reading and watching the television. These can all contribute to a balanced recreational diet.

The most asked question a parent wants answering is ‘How much videogame playing is too much? To help answer this question I devised the following checklist. It is designed to check if a child’s videogame playing is getting out of hand. Ask these simple questions. Does your child:

  • Play videogames every day?
  • Often play videogames for long periods (e.g., 3 to 6 hours at a time)?
  • Play videogames for excitement or ‘buzz’ or as a way of forgetting about other things in their life?
  • Get restless, irritable, and moody if they can’t play videogames?
  • Sacrifice social and sporting activities to play videogames?
  • Play videogames instead of doing their homework?
  • Try to cut down the amount of videogame playing but can’t?

If the answer is ‘yes’ to more than four of these questions, then your child may be playing too much. But what can you do if your child is playing videogames too much?

  • First of all, check the content of the games. Try and give children games that are educational rather than the violent ones. Parents usually have control over what their child watches on television – videogames should not be any different.
  • Secondly, try to encourage video game playing in groups rather than as a solitary activity. This will lead to children talking and working together.
  • Thirdly, set time limits on children’s playing time. Tell them that they can play for a couple of hours after they have done their homework or their chores – not before.
  • Fourthly, parents should always get their children to follow the recommendations by the videogame manufacturers (e.g., sit at least two feet from the screen, play in a well-lit room, never have the screen at maximum brightness, and never play videogames when feeling tired).

I have spent many years examining both the possible dangers and the potential benefits of videogame playing. Evidence suggests that in the right context videogames can have positive health and educational benefits to a large range of different sub-groups. What is also clear from the case studies displaying the more negative consequences of playing is that they all involved children who were excessive users of videogames. From prevalence studies in this area, there is little evidence of serious acute adverse effects on health from moderate play. In fact, in some of my studies, I found that moderate videogame players were more likely to have friends, do homework, and engage in sporting activities, than those who played no videogames at all.

For excessive videogame players, adverse effects are likely to be relatively minor, and temporary, resolving spontaneously with decreased frequency of play, or to affect only a small subgroup of players. Excessive players are the most at-risk from developing health problems although more research is needed. If care is taken in the design, and if they are put into the right context, videogames have the potential to be used as training aids in classrooms and therapeutic settings, and to provide skills in psychomotor coordination, and in simulations of real life events (e.g., training recruits for the armed forces).

Every week I receive emails from parents claiming that their sons are addicted to playing online games or that their daughters are addicted to social media. When I ask them why they think this is the case, they almost all reply “because they spend most of their leisure time in front of a screen.” This is simply a case of parents pathologising their children’s behaviour because they think what they are doing is “a waste of time.” I always ask parents the same three things in relation to their child’s screen use. Does it affect their schoolwork? Does it affect their physical education? Does it affect their peer development and interaction? Usually parents say that none of these things are affected so if that is the case, there is little to worry about when it comes to screen time. Parents also have to bear in mind that this is how today’s children live their lives. Parents need to realise that excessive screen time doesn’t always have negative consequences and that the content and context of their child’s screen use is more important than the amount of screen time.

The born identity: Can online gaming help people with gender dysphoria?

About a year ago, my colleagues and I published what we believe is the very first study of the helping role that video gaming can play in the lives of transgender individuals. Before I get to that, it’s probably worth noting that there have been studies of how gamers and fans play with sexuality, gender, and the video game Minecraft on YouTube as well as papers discussing whether the gaming industry should cater for marginalized groups and develop games for groups where there is little representation within games (e.g., gay and transgendered characters). For instance, there is now a short autobiographical game by Auntie Pixellante called Dys4ia. This is a WarioWare-style game, played only with the arrow keys, chronicling the experiences of a trans woman rectifying her own gender dysphoria. Such videogames raise interesting questions about how those individuals with gender dysphoria utilize gaming as part of their identity.

In a previous blog I briefly looked at gender swapping in online video games including some of my own research. For instance, in 2003 I published a paper in the journal CyberPsychology and Behavior using secondary poll data from online gaming forums. The paper reported that of 10,350 players at the Everlore fan site, 15% had swapped the gender of their main in-game playing character. We also reported a similar finding among 8,694 players at the Allakhazam fan site with 15.5% reporting that they had gender swapped their main in-game character (and more specifically, 14.5% males and 1% were females who had changed the gender of their lead character). In a 2004 follow-up survey among 540 Everquest gamers (again in the journal CyberPsychology and Behavior) my colleagues and I reported that 60% had swapped their online in-game characters. The prevalence of gender swapping was probably much higher in this study because the question related to the gender swapping of any online game character not just their main playing character.

In a small exploratory study I published in 2008 with Dr. Zaheer Hussain in the International Journal of Mental Health and Addiction, we examined why people engaged in gender swapping in a self-selecting sample of 119 online gamers (mean age of 28.5 years). We reported that 57% of gamers had engaged in gender swapping (any character not just their main character), and that males adopting an online female persona believed there were a number of positive social attributes to becoming female characters in male-oriented gaming environments. The study also reported that significantly more females than males had gender swapped their character – mainly to prevent unsolicited male approaches on their female characters. Some females appeared to gender swap purely out of interest to see what would happen in the game (as a personal experiment), while others claimed that they were treated more favourably by male gamers when they played as a male character. Others reported that gender swapping enabled them to play around with aspects of their identity that would not be possible to explore in real life. Other reasons for gender swapping were that (i) female characters had better in-game statistics, (ii) some specific tools were only available with female characters, (iii) the class of character was sometimes only available in one gender, (iv) they played for fun, and/or (v) they did it to so something that they would not normally do in the game (i.e., they did it for a change in their usual playing behaviour).


Outside of online gaming, a 2002 paper by Hegland and Nelson in the International Journal of Sexuality and Gender Studies noted that the Internet more generally can be used as a tool for expressing gender identity because it allows identities to cross cultural boundaries instantly and without regard for real physical space. They examined 30 cross-dressing websites and argued that for most cross-dressers that visited such websites, the online forum was their primary medium of expression. The users of the website used the Internet to nurture the ability to create a feminine identity, and helped them to pass as a woman in the offline public world. More generally, cross-dressers used the Internet to participate in the larger cultural dialogue of gender.

For an adult to meet current criteria for a diagnosis of transsexualism, the World Health Organisation’s International Classification of Diseases (ICD) reports they must express the desire to live and be accepted as a member of the opposite sex, usually accompanied by the wish to make his or her body as congruent as possible with the desired sex through surgery and cross-sex hormones. This transsexual identity must have been present persistently for a minimum of two years and not be a symptom of another mental disorder or a chromosomal abnormality. The latest (fifth) edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-5) of the American Psychiatric Association uses the term gender dysphoria to describe people who are uncomfortable and/or distressed regarding their assigned gender, their physical sex characteristics and/or their associated social roles. Depending upon the intensity of this distress, some individuals may wish to transition from one point on a notional gender scale to another. The most common direction is from a man to a woman (individuals known as trans women), or from a woman to a man (individuals known as trans men). The distress intrinsic to gender dysphoria may be focused around anatomy, physiology, and/or being perceived and treated as someone of a gender with which the person does not identify. However, these diagnostic labels do not apply to all trans individuals for a multitude of reasons because some people will not identify themselves as a man or as a woman

The World Health Organisation working group has recommended that the latest ICD replace the term Transsexualism with Gender Incongruence) and remove it from the mental and behavioural disorders chapter. Gender incongruence denotes the incongruence between a person’s gender identity and their assigned sex and/or congenital primary and secondary sex characteristics. The terminology in this field has changed over the years and the terms ‘transgender’ and ‘trans’ have been used in the literature as umbrella terms to cover a wide variety of atypical gender experiences and expressions which may lead to permanent change of social gender role but does not necessarily involve treatment with cross-sex hormones or surgical intervention. A recent study has reported an prevalence for transsexualism of 4.6 in 100,000 individuals; 6.8 for trans women and 2.6 for trans men, which is primarily based on studies looking at individuals attending clinical services. (However, it should be noted that recent population studies have reported a significantly higher prevalence rate of atypical gender experiences and expressions).

The study we published in the journal Aloma originated from initial observations made by Dr. Jon Arcelus that a number of gender dysphoric clients presenting at the national (UK) gender dysphoria clinic admitted that they gender-swapped while playing online games. After I met with Dr. Arcelus I suggested he revisit his case files and and to write them up as case studies (as no study in the gaming field has ever examined online gaming among those with gender dysphoria). The main objectives of our study were to use exemplar case studies to highlight that gaming – in some circumstances – appears to be a functional way of dealing with gender identity issues, and that gender swapping in gaming may help such individuals to come to terms with their gender dysphoria.

Our paper featured four case studies who attended an assessment at the National Centre for Gender Dysphoria in Nottingham. All four individuals described in our paper were given pseudonyms and the content of their histories were anonymised (and included ‘Mary’ a 26-year old natal male who fully transitioned to the female social role six months prior to our study; ‘Mark’ a 20-year old natal female who first attended for an assessment in the female role; ‘Paul’ a 31-year old natal male who would like to be female, but still living full-time as a male; and ‘Harry’ a 23-year old natal male who presented for an assessment as a male). If you want to read about each case in detail, the paper can be downloaded for free from here).

The four case studies outlined in our paper are only a selected sample of the number of cases attending a national clinic for people with gender dysphoria. However, they were in no way unusual to the other clients that have sought help at the Centre. However, these individual accounts were specifically selected to demonstrate the different ways that video gaming may help people with gender dysphoria come to terms with their gender identity. For example, gaming can be used among trans people as a psychological tool to increase one’s awareness of gender identity and/or as part of the self. Gaming may therefore be a useful way to express one’s experienced gender identity in a safe, non-threatening, non-alienating, non-stigmatizing, and non-critical environment. This appears to mirror other the findings of other studies outside of the online gaming environment.

Articles published in the mass media have reported that online games such as World of Warcraft provide a creative space that allows gamers that might be questioning aspects of their identity to explore their lives as different individuals. Some have even gone as far as to argue that this could help gamers transform their ‘offline’ identity, as is the case with some trans gamers. This was also demonstrated in the case studies described in our study. Other authors have asserted that the online medium offers an infinite space for development and resistance to traditional gender roles, and that online interaction enables a transgression of the dichotomous categories of male and female, constructing trans (or even genderless) social identities and relationships. However, although such anonymous online communities may provide trans individuals with the power to subvert their physical sex.

Our case studies also demonstrated the different functions of gaming in trans people (e.g., the function of “testing out” their gender feelings). For instance, using gaming to ‘come out’ to other people, by initially coming out in the online community, which is perceived as a safe environment, and then gradually coming out in real life. Gaming, as for many non-trans individuals, can derive psychological benefits and a sense of escapism. This is even more relevant among trans people as it may be the only time that they feel they can be themselves, allowing them to feel happy, relaxed, and achieving a sense of completeness. This could develop into a powerful coping skill substituting unhealthy behaviours, such as self-harming behaviour. This is particularly important in this population as research shows a strong association between being trans and mental health problems, particularly depression and self-harm as a way to manage one’s trans feelings. This is not surprising as the discomfort and distress about assigned gender and body dissatisfaction may lead to a sense of hopelessness, which can bring low mood, self-injury and even suicide.

Although gaming appears (at least initially) to be a positive and beneficial activity for many trans people, there is also the risk that staying in the game becomes too much of a secure and safe environment. This can create a vicious circle where the trans person does not wish to move out of the secure online world, and back into reality. Spending an increasing amount of time in online gaming carries the risk of developing a gaming dependence or addiction. This may not only affect one’s personal relationships, work and/or study, but may also impair real life social gender role transition, as in many cases, the individual is expected to socially transition before they can be considered for treatment.

Obviously our paper only included four participants and may be perceived by some researchers as ‘anecdotal’ because the data were not collected for this specific study but were retrospectively collated. However, our findings showed that for a trans individual, the online gaming environment was perceived as “safe” but further research is needed to establish what the distinctive elements of online gaming are that help to raise gender awareness (or not as the case may be). With the rates of gender dysphoria attending clinical services increasing significantly, future research should investigate (i) the rates and severity of gaming among this population as well as its function, and (ii) the rates of gender dysphoria among game addiction as coming out may help their addiction. The game industry may also want to consider how they can use games as a way of helping trans people being more accepted within society by developing game industry may want to co-observe how their games can prepare and assist individuals to socially transition. Online games also provide a safe environment that provides people access to a platform where individuals can discuss and experiment with gender identity.

Blocking out the pain: Tetris, trauma, and Game Transfer Phenomena

Unwanted visual intrusions are characteristic of Post-Traumatic Stress Disorder (PTSD). According to Dr. Emily Holmes and her colleagues in a 2009 paper in the journal PLoS ONE, one innovative intervention for inhibiting unwanted intrusions is playing the Tetris videogame, described as a ‘cognitive vaccine’ in preventing intrusions after traumatic events. Playing Tetris consumes heavy visuospatial working memory resources that potentially compete with cognitive resources required for elaboration of visual imagery. Since Holmes and colleagues’ study, other studies have used Tetris to inhibit intrusive imagery including more studies by Holmes and her colleagues and others by Ella James’ research group, as well as some innovative studies using Tetris to reduce drug cravings by Jessica Storka-Brown and her colleagues (see ‘Further reading’ below). However, none of these studies assessed the role of videogame content after playing in relation to Game Transfer Phenomena (GTP), an area that we have carried out a lot of research into (see ‘Further reading’ below).


GTP research has investigated non-volitional experiences (e.g., altered sensorial perceptions and automatic mental processes/behaviours) mostly experienced after gaming. Gamers often report sensorial (visual/auditory) intrusions after playing (e.g., visual and auditory imagery, hallucinations). In a survey of 2,362 gamers that we published in a 2016 issue of the International Journal of Human-Computer Interaction, most (77%) had visualized images from a variety of videogames (including tile-puzzle games) with closed-eyes, and one-third (31%) had visualized images with open-eyes. Other studies have experimentally induced videogame-related visualizations at sleep onset (including studies by Stickgold and colleagues [2000], Wamsley and colleagues [2010], Kusse and colleagues [2012] – see ‘Further reading’).

James and colleagues’ 2015 study in the journal Psychological Science was the first to make explicit reference to GTP (referred to as the ‘Tetris effect’ [TE]). In 2012, we argued the TE term is misleading as it suggests repetition is the core of transfer effects. However, other factors are involved. Research concerning GTP makes the distinction between sensorial modalities facilitating non-volitional phenomena with videogame content that occur along the continuum from mild to severe. Moreover, the descriptive constructs of GTP are empirically based on our analysis of 3,500+ gamers and have been examined via confirmatory factor analysis demonstrating good reliability and validity.

James and her colleagues tested if playing Tetris offered a protective mechanism against re-experiencing traumatic events. Healthy participants (n=56) were randomly assigned to either playing Tetris for 11 minutes, or doing nothing before exposure to a 12-minute traumatic film. Image-base memories about the film were then registered in a one-week dairy. However, playing Tetris as a proactive interference task before watching the film did not show significant results. James and colleagues offered different explanations including: (i) duration of the task in relation to film length, (ii) temporal contingencies between the tasks, (iii) differences between the task types, (iv) videogame types used, and (v) reactivation of gameplay during the film for aided interference. In a commentary paper published in a 2016 issue of Frontiers in Psychology, we discussed these findings and some of its shortcomings in relation to GTP literature.

  • Duration of task in relation to film length: Playing Tetris for 11 minutes may not have been long enough to compete with the consolidation of memory of the 12-minute film. GTP are significantly more likely to occur when playing 3-6 hours. Our research reported only 4% of gamers reported GTP when playing sessions shorter than one-hour. Laboratory experiments have taken days of playing to induce game-related visualizations at sleep onset.
  • Temporal contingencies between gaming and film watching: The tasks were performed minutes apart from each other. GTP mostly occur soon after stopping playing but our research has found that gamers have also reported GTP days after playing. In most cases, duration of experience is very short (seconds/minutes) but in some cases hours or longer.
  • Differences between the tasks: Previous studies have demonstrated that similar tasks aid interference. However, watching a film is a passive activity while gaming is interactive requiring additional perceptual/motor skills. Therefore, it may be expected that gaming is more potent as interference task, particularly because inducing the subjective sense of presence in the virtual world may strengthen the interference.
  • Type of videogame used as interference task and emotional content of film: The unrealistic (geometric) Tetris content may have been overwritten by the film’s traumatic images. Visualization of stereotypical games induced at sleep onset are characterized by lack of emotion, assuming that the amygdala and the reward system are not involved. In GTP research, emotions in tile-matching puzzle-games are incomparable to emotions in realistic videogames.
  • Reactivation of gameplay during the film for aided interference: The use of cue reminders may have potential in reviving videogame content. In many cases, thoughts and altered perceptions are triggered by game-related cues. Selective attention toward game-related cues has been demonstrated in experiments. GTP have been reported in variety of videogame genres particularly those that have very realistic graphics and settings. Therefore, more realistic games may aid associations between real life stimuli and videogame content, and may be more effective in competing with memories of traumatic events.

In our Frontiers paper, we noted that playing Tetris is not only an effective visuospatial task (overloading working memory resources needed for imagery-formation while playing), but as demonstrated in our GTP studies, videogame content stays active after playing (e.g., mental imagery, sensory perceptions), and may offer additional benefits for managing unwanted intrusions. GTP may potentially strengthen effects of interference tasks but should be used cautiously, because videogame content not only targets unwanted intrusions, but also influences individual cognitions, perceptions, and behaviours in day-to-day contexts (e.g., attention bias, lack of task awareness, control inhibition failures). Moreover, our studies have shown distress and dysfunction have been reported with GTP.

Consequently, further research needs conducting to identify: (i) videogames that are most effective, (ii) playing duration, (iii) factors that reduce intervention efficacy and strategies to control them, and (iv) individuals that may benefit the most from such intervention. While using videogames as intervention tools for preventing unwanted imagery from traumatic experiences has potential, therapeutically it is still at an early stage.

Screenagers in love: Adolescent screen time, content, and context

In 1999, the American Academy of Pediatrics (AAP) advocated the ‘2×2’ screen time guidelines to parents that their children should be restricted to no more than 2 hours of screen time a day and that children under 2 years of age should not be exposed to any screen time at all. Not only is this unworkable in today’s multi-media world but the guidelines are not based on scientific evidence. Thankfully, the AAP have revised their guidelines in the light of how today’s children actually engage with screen-based interactive technologies. For me, the issue is not about the amount of screen time but is about the content and the context of screen use. I have three ‘screenagers’ (i.e., children often referred to as ‘digital natives’ who have never known a world without the internet, mobile phones and interactive television) who all – like me – spend a disproportionate amount of their everyday lives on front of a screen for both work/educational and leisure purposes. Engaging in a lot of screen-based activities is not inherently negative – it’s simply a case of doing things differently than we did 20 years ago.


One online activity that has received a lot of criticism in the media is the playing of online videogames. However there is now a wealth of research which shows that video games can be put to educational and therapeutic uses, as well as many studies which reveal how playing video games can improve reaction times and hand-eye co-ordination. Their interactivity can stimulate learning, allowing individuals to experience novelty, curiosity and challenge that stimulates learning. Although I have published many studies concerning online gaming addiction, there is little empirical evidence that moderate gaming has any negative effects whatsoever. In fact, many excessive players experience detrimental effects.

Over the past 15 years I have spent time researching the excessive playing of online videogames like Everquest and World of Warcraft (WoW). Online gaming involves multiple reinforcements in that different features might be differently rewarding to different people. In video games more generally, the rewards might be intrinsic (e.g. improving your highest score, beating your friend’s high score, getting your name on the “hall of fame”, mastering the game) or extrinsic (e.g. peer admiration).

In online gaming, there is no end to the game and there is the potential for gamers to play endlessly. This can be immensely rewarding and psychologically engrossing. For a small minority of people, this may lead to addiction where online gaming compromises everything else in their lives. However, playing excessively doesn’t necessarily make someone an addict. A few years ago in the International Journal of Mental Health and Addiction, I published two case study accounts of two males who claimed that they were gaming for up to 80 hours a week. They were behaviourally identical in terms of their game playing, but very different in terms of their psychological motivation to play.

The first case was an unemployed single 21-year old male. His favourite online game was World of Warcraft and that since leaving university he had spent an average of 10 to 14 hours a day playing WoW. He claimed that WoW had a positive influence in his life and that most of his social life was online and that it increased his self-esteem. He also argued that he had no other commitments and that he had the time and the flexibility to play WoW for long stretches. Gaming provided a daily routine when there was little else going on. There were no negative detrimental effects in his life. When he got a job and a girlfriend, his playing all but stopped.

The second case was 38-year old male, a financial accountant, married and had two children. He told me that over the previous 18 months, his online playing of Everquest had gone from about 3-4 hours of playing every evening to playing up to 14 hours a day. He claimed that his relationship was breaking down, that he was spending little time with his children, and that he constantly rang in sick to work so that he could spend the day playing online games. He had tried to quit playing on a number of occasions but could not go more than a few days before he experienced “an irresistible urge” to play again – even when his wife threatened to leave him.

Giving up online gaming was worse than giving up smoking and that he was “extremely moody, anxious, depressed and irritable” if he was unable to play online. Things got even worse. He was fired from his job for being unreliable and unproductive (although his employers were totally unaware of his gaming behaviour). As a result of losing his job, his wife also left him. This led to him “playing all day, every day”. It was a vicious circle in that his excessive online gaming was causing all his problems yet the only way he felt he could alleviate his mood state and forget about all of life’s stresses was to play online games even more.

I argued that only the second man appeared to be genuinely addicted to online gaming but that the first man wasn’t. I based this on the context and consequences of his excessive play. Online gaming addiction should be characterized by the extent to which excessive gaming impacts negatively on other areas of the gamers’ lives rather than the amount of time spent playing. For me, an activity cannot be described as an addiction if there are few (or no) negative consequences in the player’s life even if the gamer is playing up to 14 hours a day. The difference between a healthy enthusiasm and an addiction is that healthy enthusiasms add to life, addictions take away from it.

Every week I receive emails from parents claiming that their sons are addicted to playing online games and that their daughters are addicted to social media. When I ask them why they think this is the case, they almost all reply “because they spend most of their leisure time in front of a screen”. This is simply a case of parents pathologising their children’s behaviour because they think what they are doing is “a waste of time”. I always ask parents the same three things in relation to their child’s screen use. Does it affect their schoolwork? Does it affect their physical education? Does it affect their peer development and interaction? Usually parents say that none of these things are affected so if that is the case, there is little to worry about when it comes to screen time. Parents also have to bear in mind that this is how today’s children live their lives. Parents need to realise that excessive screen time doesn’t always have negative consequences and that the content and context of their child’s screen use is more important than the amount of screen time.

Tubular hells: A brief look at ‘addiction’ to watching YouTube videos


A few days ago, I unexpectedly found my research on internet addiction being cited in a news article by Paula Gaita on compulsive viewing of YouTube videos (‘Does compulsive YouTube viewing qualify as addiction?‘). The article was actually reporting a case study from a different news article published by PBS NewsHour by science correspondent Lesley McClurg (‘After compulsively watching YouTube, teenage girl lands in rehab for digital addiction’). As Gaita reported:

“The story profiles a middle school student whose obsessive viewing of YouTube content led to extreme behavior changes and eventually, depression and a suicide attempt. The student finds support through therapy at an addiction recovery center…The student in question is a young girl named Olivia who felt at odds with the ‘popular’ kids at her Oakland area school. She began watching YouTube videos after hearing that it was a socially acceptable thing to do… Her viewing habits soon took the place of sleep, which impacted her energy and mood. Her grades began to falter, and external problems within her house – arguments between her parents and the death of her grandmother – led to depression and an admission of wanting to hang herself. Her parents took her to a psychiatric hospital, where she stayed for a week under suicide watch, but her self-harming compulsion continued after her release. She began viewing videos about how to commit suicide, which led to an attempt to overdose on Tylenol[Note: The name of the woman – Olivia – was a pseudonym].

McClurg interviewed Olivia’s mother for the PBS article and it was reported that Olivia went from being a “bubbly daughter…hanging out with a few close friends after school” to “isolating in her room for hours at a time”. Olivia’s mother also claimed that her daughter had always been kind of a nerd, a straight. A student who sang in a competitive choir. But she desperately wanted to be popular, and the cool kids talked a lot about their latest YouTube favorites”. According to news reports, all Olivia would do was to watch video after video for hours and hours on end and developed sleeping problems. Over time, the videos being watched focused on fighting girls and other videos featuring violence.


The news story claimed that Olivia was “diagnosed with depression that led to compulsive internet use”. When Olivia went back home she was still feeling suicidal and then spent hours watching YouTube videos on how to commit suicide (and it’s where she got the idea for overdosing on Tylenol tablets).

After a couple of spells in hospital, Olivia’s parents took her to a Californian centre specialising in addiction recovery (called ‘Paradigm’ in San Rafael). The psychologist running the Paradigm clinic (Jeff Nalin) claimed Olivia’s problem was “not uncommon” among clients attending the clinic. Nalin believes (as I do and have pointed out in my own writings) that treating online addictions is not about abstinence but about getting the behaviour under control but developing skills to deal with the problematic behaviour. He was quoted as saying:

“I describe a lot of the kids that we see as having just stuck a cork in the volcano. Underneath there’s this rumbling going on, but it just rumbles and rumbles until it blows. And it blows with the emergence of a depression or it emerges with a suicide attempt…The best analogy is when you have something like an eating disorder. You cannot be clean and sober from food. So, you have to learn the skills to deal with it”.

The story by Gaita asked the question of whether compulsive use of watching YouTube could be called a genuine addiction (and that’s where my views based on my own research were used). I noted that addiction to the internet may be a symptom of another addiction, rather than an addiction unto itself. For instance, people addicted to online gambling are gambling addicts, not internet addicts. An individual addicted to online gaming or online shopping are addicted to gaming or shopping not to the internet.

An individual may be addicted to the activities one can do online and is not unlike saying that an alcoholic is not addicted to a bottle, but to what’s in it. I have gone on record many times saying that I believe anything can be addictive as long there are continuous rewards in place (i.e., constant reinforcement). Therefore, it’s not impossible for someone to become addicted to watching YouTube videos but the number of genuine cases of addiction are likely to be few and far between. Watching video after video is conceptually no different from binge watching specific television series or television addiction itself (topics that I have examined in previous blogs).

I ought to end by saying that some of my own research studies on internet addiction (particularly those co-written with Dr. Attila Szabo and Dr. Halley Pontes and published in the Journal of Behavioral Addictions and Addictive Behaviors Reports – see ‘Further reading’ below) have examined the preferred applications by those addicted to the internet, and that the watching of videos online is one of the activities that has a high association with internet addiction (along with such activities such as social networking and online gaming). Although we never asked participants to specify which channel they watched the videos, it’s fair to assume that many of our participants will have watched them on YouTube), and (as the Camelot lottery advert once said) maybe, just maybe, a few of those participants may have had an addiction to watching YouTube videos.

Games without frontiers: A brief look at the psychology of play

In a previous blog I examined my favourite board game (Scrabble) and the extent to which someone could become addicted to it. Today’s blog takes a broader look at the psychology of play more generally. Arguably, many of the topics that I research involve the psychology of playing games with video games and gambling games being my two most obvious areas of interest.

It’s been argued by myself (and others) that the ritualized play of several childhood games provides ‘training’ in the acquisition of gambling behaviour and that some games are pre-cursors to actual gambling (e.g., playing marbles, card flipping, etc.). Some authors (such as Igor Kusyszyn) hold the view that gambling is in itself ‘adult play’. Unsurprisingly, Freud was one of the first people to concentrate on the ‘functions’ of play and concluded that play in all its varieties (a) provides a wish-fulfilment, (b) leads to conflict reduction, (c) provides temporary leave of absence from reality, and (d) brings about a change from the passive to the active.


Since Freud, most psychologists have concentrated on the idea of ‘conflict reduction’ and in doing so have ignored his other three postulations. A more modern approach in the 1970s by Mihalyi Czikszentmihalyi asserted that during play a person can “concentrate on a limited stimulus field, in which he or she can use skills to meet clear demands, thereby forgetting his or her own problems and separate identity” (and provides one of the reasons that a small minority of people can develop problems playing games). Seminal research on the sociology of play by Roger Caillois states notes that play is a “free and voluntary activity”, “a source of joy and amusement” and “bounded by precise limits of time and space” whereas Erving Goffman views it as a “world building activity”.

Games provide the opportunity to prove one’s superiority, the desire to challenge and overcome an obstacle, and a medium by which to test one’s skill, endurance and ingenuity. Games, unlike some activities (including life itself!), tell us whether we have won or lost. As observed by James Smith and Vicki Abt in the 1980s:

“…in the context of a competitive and materialistic culture that has become increasingly regimented and standardized with little room for individual creativity and personal achievement, games (including gambling) offer the illusion of control over destiny and circumstance”.

Perhaps the best categorisation of game types was formulated by Roger Caillois who listed four classifications – agon (competition), alea (chance), mimicry (simulation), and ilinx (vertigo). In the context of games involving gambling, alea and agon are crucial in that they offer a combination of skill, chance and luck. As was previously asserted, most people desire opportunities to test their strength and skill against an adversary, and those games which offer a component of skill or talent combined with luck and chance provide the most favourable conditions. This is particularly prevalent in males who are deemed ‘masculine’ if during the socialization process they show (socially) important traits such as courage, independence, and bravery.

According to Caillois, play is “an occasion of pure waste: waste of time, energy, ingenuity, skill, and often of money” and is a “free and voluntary activity that occurs in a pure space, isolated and protected from the rest of life”. According to Caillois, play is best described by six core characteristics:

  • It is free, or not obligatory.
  • It is separate (from the routine of life) occupying its own time and space.
  • It is uncertain, so that the results of play cannot be pre-determined and so that the player’s initiative is involved.
  • It is unproductive in that it creates no wealth and ends as it begins.
  • It is governed by rules that suspend ordinary laws and behaviours and that must be followed by players.
  • It involves make-believe that confirms for players the existence of imagined realities that may be set against ‘real life’.

Back in 2000, I published an article on the psychology of games in Psychology Review and what makes a good game. I noted that:

  • All good games are relatively easy to play but can take a lifetime to become truly adept. In short, there will always room for improvement.
  • For games of any complexity there must be a bibliography that people can reference and consult. Without books and magazines to instruct and provide information there will be no development and the activity will die.
  • There needs to be competitions and tournaments. Without somewhere to play (and likeminded people to play with) there will be little development within the field over long periods of time.
  • Finally – and very much a sign of the times – no leisure activity can succeed today without corporate sponsorship of some kind.

I was recently interviewed by Lucy Orr for an article on board games for The Register – particularly about the psychology of winning. For instance, why is winning so important? I responded to Orr by pointing out that winning makes us feel good both psychologically and physiologically. Winning something – especially if it is a result of something skilful rather than by chance – can feel even better (unless the chance winning is something life changing like winning the lottery). Winning something using your own skill can demand respect from other competitors and brings about esteem (that can feed into one’s own self-esteem). Winning can be a validation that what you are doing is worthwhile. Other parts of my interview were not used.

I was asked whether beating other people makes winning more rewarding? Of course it does. Any time we engage in a behaviour that feels good we want to do it again (and again). Winning can be reinforcing on many different levels. There may be financial rewards, social rewards (peer praise, admiration and respect from others), psychological rewards (feeling better about oneself and feeling that the activity is a life-affirming and life-enhancing activity that feeds into self-esteem), and physiological rewards (increases in adrenaline and serotonin that trigger dopamine and makes us feel happy).

For some people, winning can become addictive. You can’t become addicted to something unless you are constantly reinforced and rewarded for engaging in the behaviour, and (as mentioned above) there are many different types of rewards (e.g., financial, social, psychological and physiological). Any (or all of these) could lead to repetitive and habitual behaviour and in a small minority of cases be addictive. However, as I have noted in a number of my papers, doing something to excess is not addiction. The difference between a healthy excessive enthusiasm and an addiction is that excessive enthusiasms add to life and addictions take away from it. For most people, winning behaviour – particularly in the context of playing board games – will be highly rewarding without being in any way problematic

A diction for addiction: A brief overview of our papers at the 2017 International Conference on Behavioral Addictions

This week I attended (and gave one of the keynote papers at) the fourth International Conference on Behavioral Addictions in Haifa (Israel). It was a great conference and I was accompanied by five of my colleagues from Nottingham Trent University all of who were also giving papers. All of the conference abstracts have just been published in the latest issue of the Journal of Behavioral Addictions (reprinted below in today’s blog) and if you would like copies of the presentations then do get in touch with me.


Griffiths, M.D. (2017). Behavioural tracking in gambling: Implications for responsible gambling, player protection, and harm minimization. Journal of Behavioral Addictions, 6 (Supplement 1), 2.

  • Social responsibility, responsible gambling, player protection, and harm minimization in gambling have become major issues for both researchers in the gambling studies field and the gaming industry. This has been coupled with the rise of behavioural tracking technologies that allow companies to track every behavioural decision and action made by gamblers on online gambling sites, slot machines, and/or any type of gambling that utilizes player cards. This paper has a number of distinct but related aims including: (i) a brief overview of behavioural tracking technologies accompanied by a critique of both advantages and disadvantages of such technologies for both the gaming industry and researchers; (ii) results from a series of studies carried out using behavioural tracking (particularly in relation to data concerning the use of social responsibility initiatives such as limit setting, pop-up messaging, and behavioural feedback); and (c) a brief overview of the behavioural tracking tool mentor that provides detailed help and feedback to players based on their actual gambling behaviour.

Calado, F., Alexandre, J. & Griffiths, M.D. (2017). Youth problem gambling: A cross-cultural study between Portuguese and English youth. Journal of Behavioral Addictions, 6 (Supplement 1), 7.

  • Background and aims: In spite of age prohibitions, most re- search suggests that a large proportion of adolescents engage in gambling, with a rate of problem gambling significantly higher than adults. There is some evidence suggesting that there are some cultural variables that might explain the development of gambling behaviours among this age group. However, cross­cultural studies on this field are generally lacking. This study aimed to test a model in which individual and family variables are integrated into a single perspective as predictors of youth gambling behaviour, in two different contexts (i.e., Portugal and England). Methods: A total of 1,137 adolescents and young adults (552 Portuguese and 585 English) were surveyed on the measures of problem gambling, gambling frequency, sensation seeking, parental attachment, and cognitive distortions. Results: The results of this study revealed that in both Portuguese and English youth, the most played gambling activities were scratch cards, sports betting, and lotteries. With regard to problem gambling prevalence, English youth showed a higher prevalence of problem gambling. The findings of this study also revealed that sensation seeking was a common predictor in both samples. However, there were some differences on the other predictors be- tween the two samples. Conclusions: The findings of this study suggest that youth problem gambling and its risk factors appear to be influenced by the cultural context and highlights the need to conduct more cross-cultural studies on this field.

A new tool to assess the psychological features of reward deficiency. Journal of Behavioral Addictions, 6 (Supplement 1), 11.

  • ‘Reward Deficiency Syndrome’ (RDS) is a theory assuming that specific individuals do not reach a satisfactory state of reward due to the functioning of their hypodopaminergic reward system. For this reason, these people search for further rewarding stimuli in order to stimulate their central reward system (i.e., extreme sports, hypersexuality, substance use and/or other addictive behaviors such as gambling, gaming, etc.). Beside the growing genetic and neurobiological evidence regarding the existence of RDS little re- search has been done over the past two decades on the psychological processes behind this phenomenon. The aim of the present paper is to provide a psychological description of RDS as well as to present the development of the Reward Deficiency Syndrome Questionnaire (developed using a sample of 1,726 participants), a new four-factor instrument assessing the different aspects of reward deficiency. The results indicate that four specific factors contribute to RDS comprise “lack of satisfaction”, “risk seeking behaviors”, “need for being in action”, and “search for overstimulation”. The paper also provides psychological evidence of the association between reward deficiency and addictive disorders. The findings demonstrate that the concept of RDS provides a meaningful and theoretical useful context to the understanding of behavioral addictions.

  • Background and aims: The Ten-Item Internet Gaming Disorder Test (IGDT-10) is a brief instrument developed to assess Internet Gaming Disorder as proposed in the DSM­5. The first psychometric analyses carried out among a large sample of Hungarian online gamers demonstrated that the IGDT-10 is a valid and reliable instrument. The present study aimed to test the psychometric properties in a large cross-cultural sample. Methods: Data were collected among Hungarian (n = 5222), Iranian (n = 791), Norwegian (n = 195), Czech (n = 503), Peruvian (n = 804), French­speaking (n = 425) and English­ speaking (n = 769) online gamers through gaming­related websites and gaming-related social networking site groups. Results: Confirmatory factor analysis was applied to test the dimensionality of the IGDT-10. Results showed that the theoretically chosen one-factor structure yielded appropriate to the data in all language­based subsamples. In addition, results indicated measurement invariance across all language-based subgroups and across gen- der in the total sample. Reliability indicators (i.e., Cronbach’s alpha, Guttman’s Lambda-2, and composite reliability) were acceptable in all subgroups. The IGDT- 10 had a strong positive association with the Problematic Online Gaming Questionnaire and was positively and moderately related to psychopathological symptoms, impulsivity and weekly game time supporting the construct validity of the instrument. Conclusions: Due to its satisfactory psychometric characteristics, the IGDT-10 appears to be an adequate tool for the assessment of internet gam- ing disorder as proposed in the DSM-5.

  • Background: To date, the evidence base for school-delivered prevention programs for positive digital citizenship for adolescents is limited to internet safety programs. Despite the inclusion of Internet Gaming Disorder (IGD) as a pro- visional disorder in the DSM-5, with arguable worrying prevalence rates for problematic gaming across countries, and a growing societal concern over adolescents’ digital use, no scientifically designed digital citizenship programs have been delivered yet, addressing positive internet use among adolescents. Methods: A systematic database search of quantitative and qualitative research evidence followed by a search for governmental initiatives and policies, as well as, non­profit organizations’ websites and reports was conducted to evaluate if any systematic needs assessment and/or evidence-based, school delivered prevention or intervention programs have been conducted in the UK, targeting positive internet use in adolescent populations. Results: Limited evidence was found for school-based digital citizenship awareness programs and those that were identified mainly focused on the areas of internet safety and cyber bullying. To the authors’ knowledge, no systematic needs assessment has been conducted to assess the needs of relevant stakeholders (e.g., students, parents, schools), and no prevention program has taken place within UK school context to address mindful and positive digital consumption, with the exception of few nascent efforts by non­profit organizations that require systematic evaluation. Conclusions: There is a lack of systematic research in the design and delivery of school-delivered, evidence-based prevention and intervention programs in the UK that endorse more mindful, reflective attitudes that will aid adolescents in adopting healthier internet use habits across their lifetime. Research suggests that adolescence is the highest risk group for the development of internet addictions, with the highest internet usage rates of all age groups. Additionally, the inclusion of IGD in the DSM-5 as provisional disorder, the debatable alarming prevalence rates for problematic gaming and the growing societal focus on adolescents’ internet misuse, renders the review of relevant grey and published research timely, contributing to the development of digital citizenship programs that might effectively promote healthy internet use amongst adolescents.

  • Despite being one of the most popular activities among adolescents nowadays, robust measures of Social Media use and representative prevalence estimates are lacking in the field. N = 5961 adolescents (49.2% male; mean age 16.6 years) completed our survey. Results showed that the one-factor Bergen Social Media Addiction Scale (BSMAS) has appropriate psychometric properties. Based on latent pro le analysis, 4.5% of the adolescents belonged to the at-risk group, who reported low self-esteem, high level of depression and the elevated social media use (34+ hours a week). Conclusively, BSMAS is an adequate measure to identify those adolescents who are at risk of problematic Social Media use and should therefore be targeted by school-based prevention and intervention programs.

  • Background and aims: To our best knowledge, no scale ex- ists with strong psychometric properties assessing problematic pornography consumption which is based on an over- arching theoretical background. The goal of the present study was to develop a short scale (Problematic Pornography Consumption Scale; PPCS) on the basis of Griffiths` (2005) six-component addiction model that can assess problematic pornography consumption. Methods: The sample comprised 772 respondents (390 females; Mage = 22.56, SD = 4.98 years). Items creation was based on the definitions of the components of Griffiths’ model. Results: A confirmatory factor analysis was carried out leading to an 18­item second­order factor structure. The reliability of the PPCS was good and measurement invariance was established. Considering the sensitivity and specificity values, we identified an optimal cut­off to distinguish between problematic and non-problematic pornography users. In the present sample, 3.6% of the pornography consumers be- longed to the at-risk group. Discussion and Conclusion: The PPCS is a multidimensional scale of problematic pornography consumption with strong theoretical background that also has strong psychometric properties.
