To infinity (and beyond): The benefits of endless running videogames
Last week I was contacted by a journalist at the Red Bulletin Magazine who was “looking for an expert in gaming psychology to talk to for a piece on the mental benefits of endless running games, i.e. ‘the gameplay building strong reward learning in players’. It should be a fun and practical guide…Just let me know if you’d be interested.” I was interested. I had been teaching in the morning so I didn’t get the email until a couple of hours after it had been sent. I scribbled down a few notes, got back in touch, but by the time I did, the journalist had already interviewed someone else for the feature. Since I’d already made a few bullet points, I thought I would use them for the basis of a blog. (I really don’t like things going to waste).
Although much of my research examines problematic gaming, I am not anti-gaming (and never have been), and I have published many papers on the benefits of gaming including therapeutic benefits, educational benefits, and psychological (cognitive) benefits (see ‘Further reading’ below). Some of you reading this may not know what endless running games are, so here is the Wikipedia definition from its entry on platform games:
“‘Endless running’ or ‘infinite running’ games are platform games in which the player character is continuously moving forward through a usually procedurally generated, theoretically endless game world. Game controls are limited to making the character jump, attack, or perform special actions. The object of these games is to get as far as possible before the character dies. Endless running games have found particular success on mobile platforms. They are well-suited to the small set of controls these games require, often limited to a single screen tap for jumping. Games with similar mechanics with automatic forward movement, but where levels have been pre-designed, or procedurally generated to have a set finish line, are often called “auto-runners” to distinguish them from endless runners”.

Endless running games are incredibly popular and played by millions of individuals around the world (including myself on occasions). One of the best things about endless running games is that because they can be played on smartphones and other small hand-held devices they can be played anywhere at any time. Like any good game, the rules are easy to understand, the gameplay is deceptively simple, but in the end, it takes skill to succeed. The simplicity of endless running games is one of the key reasons for their global success in terms player numbers. For successful games, the mechanics should be challenging but not impossible. Such games can lead to what has been described as a state of ‘flow’ (coined by Mihaly Csíkszentmihályi in his seminal books Flow: The Psychology of Optimal Experience [1990] and Flow: The Psychology of Happiness [1992]).
With the flow experience, a game player derives intense enjoyment by being immersed in the gaming experience, the challenges of the game are matched by the player’s skills, and the player’s sense of time is distorted so that time passes without it being noticed. For some video game players, this may then mean repeatedly seeking out similar experiences on a regular basis to the extent that they can escape from their concerns in the ‘real world’ by being continually engrossed in a flow-inducing world. However, something like flow – viewed largely as a positive psychological phenomenon – may be less positive in the long-term for some video game players if they are craving the same kind of emotional ‘high’ that they obtained the last time that they experienced flow when playing a video game.
Flow has been proposed (by Jackson and Eklund, 2006) as comprising nine elements that include: (i) striking a balance between the challenges of an activity and one’s abilities; (ii) a merging of performance of actions with one’s self-awareness; (iii) possessing clear goals; (iv) gaining unambiguous feedback on performance; (v) having full concentration on the task in hand; (vi) experiencing a sense of being in control; (vii) losing any form of self-consciousness; (viii) having a sense of time distorted so that time seems to speed up or slow down; and (ix) the undergoing of an auto-telic experience (e.g., the goals are generated by the person and not for some anticipated future benefit). Endless running games are one of many types of videogame that can result in ‘flow’ experiences (which for the vast majority of gamers is going to result in something more positive (psychologically) than negative.
There are many studies showing that playing video games can improve reaction times and hand-eye co-ordination. For example, research has shown that spatial visualisation ability, such as mentally rotating and manipulating two- and three-dimensional objects, improves with videogame playing. Again, endless running videogames rely very heavily on hand-eye co-ordination and fast reaction to on-screen events. In this specific area, I see endless running games as having nothing but positive benefits in terms of improving hand-eye co-ordination skills, reflexes, and attention spans.
Although I’m not a neuroscientist or a neuropsychologist, I know that on a neurobiological level, when we engage in pleasurable activity, our bodies produce its own opiate-like neurochemicals in the form of endorphins and dopamine. The novelty aspects of endless running games will for many players result in the production of neurochemical pleasure which is rewarding and reinforcing for the gamer.
I also believe that endless running games have an appeal that crosses many demographic boundaries, such as age, gender, ethnicity, or educational attainment. They can be used to help set goals and rehearse working towards them, provide feedback, reinforcement, self-esteem, and maintain a record of behavioural change in the form of personal scores. Beating one’s own personal high scores or having higher scores than our friends and fellow gamers can also be psychologically rewarding.
Because video games can be so engaging, they can also be used therapeutically. For instance, research has consistently shown that videogames are excellent cognitive distractors and can help reduce pain. Because I have a number of chronic and degenerative health conditions, I play a number of cognitively-engrossing casual games because when my mind is 100% engaged in an activity I don’t feel any pain whatsoever. Again, endless running games tick this particular box for me (and others). Also, on a personal level, I am time-poor because I work so hard in my job. Endless running games are ideal for individuals like myself who simply don’t have the time to engage in playing massively multiplayer online games that can take up hours every day but will quite happily keep myself amused and pain-free on my commute into work on the bus.
As I have pointed out in so many of my research papers and populist writings over the years, is that the negative consequences of playing almost always involve a minority of individuals that are excessive video game players. There is little evidence of serious acute adverse effects on health from moderate play, endless running games included.

Profess on excess in the press: Problematic gaming as a behavioural addiction
As a Professor of Behavioural Addiction, one of duties is to profess. Consequently, today’s blog contains content from an interview that I did on problematic gaming as a behavioural addiction for a Spanish magazine. Because the published version was in Spanish I thought my blog readers might be interested in what I had to profess about behavioural addiction in its simplest terms (plus I never like to see things to be left unused or go to waste!).
The focus of your work is mainly behavioural addiction, could you start by giving a brief overview of what behavoural addiction is?
Behavioural addictions are those addictions that do not involve the ingestion of a psychoactive substance such as alcohol, nicotine or heroin. Some people believe that a person cannot become addicted to something in the absence of a psychoactive agent, but it is my passionate belief that people can become addicted to non-chemical behaviours. I have written a number of papers over the past 30 years that have tried to show that some behaviours when taken to excess (e.g., gambling, video gaming) are no different from (say) alcoholism or heroin addiction in terms of the core components of addiction (e.g. salience, tolerance, withdrawal, mood modification, conflict, relapse etc.). If it can be shown that a behaviour like pathological gambling can be a bona fide addiction (and I believe that it can), then there is a precedent that any behaviour that provides continuous rewards (in the absence of a psychoactive substance) can be potentially addictive. Such a precedent ‘opens the floodgates’ for other excessive behaviours to be considered theoretically as potential addictions (e.g. exercise, sex, eating, computer games, the internet) which is what I’ve been examining in some of my research.
Whilst a lot of work is around gambling addictions, you also do work on videogame addiction. What drew you to this area of research?
I suppose the ‘classic’ behavioural addiction is gambling, and it was this type of behavioural addiction that fuelled my interest in other forms of non-chemical addiction such as videogame addiction. Many people might think it’s obvious why a psychologist would be interested in studying behavioural addictions such as videogame addiction. It’s a ‘sexy’ subject, it’s media-friendly, the general public find it interesting, and almost everybody from all walks of life has some kind of view on it, whether it’s rooted in personal experience or in a finely argued theoretical perspective.
Do you feel that online gaming poses more of an issue than offline?
Yes, but in most cases only to those that have a vulnerability or susceptibility in the first place. The key difference is that in offline gaming a player can typically pause and/or save the game and come back to it a point of their choosing. Online games continue even when the player has logged off and that can lead to some people playing excessively because they ‘don’t want to miss anything’ in a 24/7 playing environment (the so-called ‘FOMO’ phenomenon – ‘fear of missing out’). I’ve argued in a lot of my work that the internet can enhance and/or facilitate the acquisition, development and maintenance of online addictions – but the crucial factor is that somebody would have to have some kind of addiction predisposition in the first place.
Are there any potential problems, in your field or otherwise, that could arise from the rapidly expanding user base of video games?
Obviously this depends on the types of game played and their content. Any activity that has the potential to enhance or facilitate excessive play can lead to potential problems. Depending on the types of game played, this could be in the form of medical effects (repetitive strain injuries, headaches, eye-strains, etc.), chronic health conditions (e.g., obesity), psychobiological effects (e.g., addiction), or alleged behavioural effects (e.g., increased aggression). The good news is that most of these potential effects occur in a very small minority of players and that reducing the time spent playing will almost always alleviate or eliminate such problems.
Can a person could spend a great deal of times playing games without being an addict?
For some people, definitely. Any behaviour that is done to excess – even if it is not an addiction – can potentially take away time from other important things such as job, relationships, and other hobbies. This will depend on the duties, constraints and context of the person in question. A 21-year old man with no partner, no children and no job may have time to play 8-10 hours a day without any negative detriment on their life. However, a married man with three children and a full-time job would find it very hard to play 8-10 hours a day without it seriously compromising some other aspect of their life.

(Loot) boxing clever? Has child and adolescent problem gambling really risen in the UK?
A couple of months ago, teenage gambling was grabbing the media headlines. The UK Gambling Commission published its annual statistics showing that based on a self-report survey of 2865 children and adolescents aged 11-16 year-olds, that the prevalence of problem gambling had risen to 1.7% (2% for boys and 1.3% for girls) compared to 0.4% in 2016 and 0.9% in 2017. This lead to predictable headlines such as “Number of child gamblers quadruples in just two years”.
I’ve been researching adolescent gambling for over three decades and was the topic for my first two books in 1995 and 2002. While the figures were concerning, the good news is that the prevalence of adolescent problem gambling has been on the decline in the UK over the past 20 years. For instance, the prevalence of adolescent problem gambling back in 2000 was approximately 5% but by 2016 was less than one-tenth of that. The rise over the past two years is a potential worry although the Gambling Commission’s ‘technical annex’ report about the methodology used to collect the data for the latest survey did suggest that one of the main reasons for the significant increase in problem gambling was likely due to a change in the way data were collected.
In short, the filtering questions in the latest study were changed (so that they more matched the adult gambling prevalence surveys that are carried out) which lead to a doubling of teenagers completing the problem gambling screen that was used to assess problem gambling (18% completing the problem gambling screen in 2017 compared to 34% in 2018). However, it is still worth noting that using the same methodology, there was more than a doubling of adolescent problem gambling from 2016 to 2017 (0.4% to 0.9%).
If there has been a genuine increase in adolescent problem gambling over the past couple of years, I think one of the main factors in this is the playing of simulated gambling games (or gambling-like activities such as the buying of loot boxes) in video games. The Gambling Commission’s report noted that 13% had played gambling-style games online, and that 31% had accessed loot boxes in a videogame or app, to try to acquire in-game items.
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, armour). 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 and these require the paying of real money in exchange for a completely random in-game item.
At present, 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 appears 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. 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.
A study published in the journal PLoS ONE claimed they had evidence for a link between the amount that videogame players spent on loot boxes and problem gambling severity in a large survey of 7422 gamers. The paper concluded that:
“This link was stronger than a link between problem gambling and buying other in-game items with real-world money…suggesting that the gambling-like features of loot boxes are specifically responsible for the observed relationship between problem gambling and spending on loot boxes”
However, this evidence is correlational not causal. I’ve also cited empirical research in my academic papers that engaging in simulated gambling within videogames is a risk factor for both gambling with real money and problem gambling. In November 2018, the Mail on Sunday (MoS) published some of my concerns after they interviewed me about the issue of simulated gambling in online videogames. Although no real money is staked, I have argued that such activities normalize gambling for children and that such activities behaviourally condition children towards gambling.
The MoS claimed that I said that children should be banned from playing online games such as Candy Crush. What I actually said was that children should be prohibited from engaging in gambling simulations within videogames. Candy Crush now features a gambling-type element in the form of a ‘wheel of fortune’ type game (which has also been used in other videogames like Runescape and which I have also argued are gambling when players have to pay to spin the wheel) and that children should be prohibited from accessing such gambling-like features. There is no evidence that the playing of Candy Crush causes problematic behaviour but the playing of simulated gambling-type games has been shown to be a risk factor for problem gambling among adolescents.
The question as to whether there has been a genuine increase in problem gambling among children and adolescents cannot be answered from the Gambling Commission’s latest report but based on other pieces of research there does appear to have been a slight rise over the past couple of years.

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.

Ga(y)ming studies: The importance of sexuality in video gaming
Back in May 2014, hundreds of news outlets reported on Nintendo’s decision not to allow gamers to play as gay characters and form same-sex relationships in the life-simulation game Tomodachi Life. Understandably, there was disquiet and outrage from a number of quarters despite Nintendo’s statement that “Tomodachi Life was intended to be a whimsical and quirky game [and] not trying to provide social commentary”. Their statement at the time appeared to fan the flames rather than silence the critics.
I have been researching video game play for almost three decades and I’ve always found issues surrounding character formation, sexuality, and gender in gaming of great psychological interest. In one of our studies we found that a majority of gamers (57%) had gender-swapped their game character with female gamers (68%) being more likely to gender swap than male gamers (54%). We argued that gender swapping enabled gamers to play around and experiment with various aspects of their in-game character that are not so easy to do in real life. For others it was just fun to see if they felt any different playing a different gendered character. What makes our findings interesting is that in most instances, the gamers had the opportunity to choose the gender of their character and to develop other aspects of their character before they began to play. Choosing to gender swap may have had an effect on the gamers’ styles of play and interaction with other gamers. Whatever the reasons, it was clear from our research that the development of gamers’ online characters and avatars was important to them.
One of the reasons for the importance of online gaming identities may be because it subverts traditional parasocial interaction (PI). PI is a concept used by psychologists that has traditionally described one-sided, parasocial interpersonal relationships in situations where one individual knows a great deal about someone else, but where the other person knows little about the other (the most common being the relationship between celebrities and their fans).
A study led by Nicholas Bowman (and published in a 2012 issue of the journal Cyberpsychology, Behavior and Social Networking [CPBSN]) argued that the playing of video games challenges this concept “as the distance between game players and characters is greatly reduced, if not completely removed, in virtual environments.” The study claimed that online gaming encourages the “psychological merging of a player’s and a character’s mind” and is critical in the development of character attachment. In this context, the sexuality of a character for a player may be of fundamental psychological importance.
This appears to be confirmed in a paper by Melissa Lewis and colleagues (also published in CPBSN) who developed a scale to assess ‘character attachment’ (“the connection felt by a video game player toward a video game character”). They found that character attachment had a significant relationship with self-esteem, addiction, game enjoyment, and time spent playing games.
American researcher Dr. Adrienne Shaw has carried out a number of studies into lesbian, gay, bisexual, and transgender (LGBT) representation in video games from a cultural production perspective. She was one of the first academics in the gaming studies field to note that there was a relative lack of LGBT representation in video games. Other areas of the entertainment media (e.g., music, film, and television) appear to have much greater LGBT representation than in video games so it does beg the question of why the gaming industry appears to be behind in this respect. I recall writing a paper back in 1993 (in The Psychologist) where I argued that most video games at the time were designed by males for other males. This arguably alienated female gamers but eventually led to developers introducing strong female characters into video games (the most notable being Lara Croft in Tomb Raider). Maybe the appearance of LGBT characters and role models within games will increase over time but I’m not holding my breath.
In a more recent paper in a 2012 paper in the journal New Media and Society, Dr. Shaw claimed that the demand for minority representation in video games “often focuses on proving that members of marginalized groups are gamers” and that the gaming industry should focus on appealing to such players via targeted content. However, she argues that an individual’s identity as a gamer will intersect with “other identities like gender, race, and sexuality.” She then goes on to say that the negative connotations about being an online gamer may lead to such marginalized groups not wanting to engage in gaming. She concluded that “those invested in diversity in video games must focus their attention on the construction of the medium, and not the construction of the audience…[This] is necessary to develop arguments for representation in games that do not rely on marking groups as specific kinds of gaming markets via identifiers like gender, race, and sexuality.”
Nintendo’s decision not to allow gay relationships to form within Tomodachi Life was ill-judged, ill-informed, and outdated. Games in which identity content can be generated by its users needs to reflect the world in which the gamers’ live. In short, there should be no compromise when it comes to allowing gamers to choose their sexuality within the game.
