Dispensing wisdom: ATMs on the gaming floor

The gambling industry has long been trying to perfect techniques that keep players on their premises and gambling on their games longer. In short, their aim is to introduce facilities that maximize their bottom line profits. In super-casinos around the world, restaurants are often positioned in the centre so that customers have to pass the gaming areas before and after they have eaten. Live entertainment areas for music or sporting events (e.g., boxing matches) are also positioned similarly.

This strategy is often combined with the deliberate use of circuitous paths to keep customers in the casino longer, the psychology being that if the patrons are in the casino longer they will spend more money. Large US casinos have got this down to a fine art. A number of years ago I remember going to a live music concert at the MGM Grand in Las Vegas and on entering the casino it took me a 20- to 25-minute walk past thousands of slot machines and gaming tables before I even arrived at the auditorium! Although I didn’t gamble during the 45 minutes I was exposed to the slot machines to and from the casino entrance, I did wonder how many of the thousands in the audience had succumbed at some point.

UK gambling venues are now increasingly offering other non-gambling services (such as snack facilities and live entertainment) in a bid to either attract new customers or to keep those already in the venue as long as possible. The 2005 Gambling Act allowed even more of this diversification. It is also worth noting that some forms of gambling (such as slot machines) are far more profitable than other forms (such as table games). What’s more, slot machines don’t need a croupier to deal or spin the roulette ball. This means that most casinos worldwide are now dominated by slot machines in preference to other forms of gambling (although there are places like Macao where table games are preferred over slot machines).

Two of the biggest changes that have occurred in casinos worldwide over the last 20 years that appear to aid such a ‘maximisation’ strategy are the introduction of cash machines onto the gaming floors and the introduction of note acceptors to electronic gaming machines. At a very simplistic level, facilities like these create and enhance convenience gambling.

Note acceptors are very popular in countries like US, Canada and Australia. The gaming industry argues that note acceptors are popular with customers and enhance the playing experience in that they make life a little bit easier for the punter when standing in front of a slot machine not to have to keep going to the cashier for change. However, there is a very fine line between customer enhancement and customer exploitation. Note acceptors have the capacity to increase spending in a number of direct and indirect ways. Firstly, note acceptors increase privacy for the punter. More specifically for the punter, it avoids the potential embarrassment of letting gaming staff, friends, family or even other customers know how much they are spending. Secondly, note acceptors can aid in suspending judgment whereby more cash is transferred to credit in one go. Thirdly, note acceptors minimise breaks as players do not need to leave the machine to get change. Not taking breaks minimises ‘time out’ periods where punters can think more rationally about the money they have spent. A study carried out in Canadian casinos showed that the amount initially put into a slot machine by punters was twice as high on machines that had note acceptors. Although this is only one study, it does seem to suggest that gamblers spend more when a note acceptor is present. 

Like note acceptors, the introduction of automated cash dispensers onto the casino floor also increases privacy for the punter. Although studies have found that only a relatively small proportion of casino patrons seldom use cash dispensers at gambling venues, a significantly high proportion of problem gamblers do so. One study in New Zealand carried out by Professor Max Abbott found that only 2% of all adults interviewed in a national survey considered that greater access to these facilities led to an increase in their gambling. Among problem gamblers, this figure was over eight times as high at 17%.

In Australia, a study led by Professor Jan McMillen also found much greater cash dispenser usage at gambling venues by problem gamblers when compared to non-problem gamblers. They also found that problem gamblers withdrew larger amounts.  Money accessed in this way was most often for the purchase of both alcohol and gambling. They concluded that convenient access to cash dispenders in gambling venues contributed to greater expenditure and was a contributory factor in the development and persistence of gambling problems.

A number of other studies have reported similar findings. Problem gamblers frequently mention that adjacent access to cash dispensers is one of the most frequently mentioned reasons for gambler’s exceeding their planned spending limit. Research has also shown that both problem and non-problem gamblers would prefer cash dispensers to be located away from gambling venues. It would seem that the only people who want cash dispensers on gambling premises are the operators themselves, mainly because they know it increases revenue.

Against all odds: The rise and rise of gambling

In many areas of the world, gambling has become a popular activity. Almost all national surveys into gambling have concluded that most people have gambled at some point in their lives, there are more gamblers than non-gamblers, but that most participants gamble infrequently. Commissions and official government reviews in a number of countries including the United States, United Kingdom, Australia and New Zealand have all concluded that increased gambling availability has led to an increase in problem gambling. Estimates of the number of problem gamblers vary from country to country but most countries that have carried out national prevalence surveys suggest around 0.5%-2% of individuals have a gambling problem.

In May 2013, the new criteria for problem gambling (now called ‘Gambling Disorder’) were published in the fifth edition of the American Psychiatric Association’s Diagnostic and Statistical Manual for Mental Disorders (DSM-5), and for the very first time, problem gambling was included in the section ‘Substance-related and Addiction Disorders’ (rather than in the section on impulse control disorders). Also included in the Appendix of the DSM-5 as a potential addiction was Internet Gaming Disorder (i.e., online video game addiction). Although most of us in the field had been conceptualizing problematic gambling and video gaming as addictions for many years, this was arguably the first time that an established medical body had described them as such. For me, gambling and gaming addictions should not be considered any differently from other more traditional chemical addictions (e.g., alcohol addiction, nicotine addiction). Consequently, there is no theoretical reason why other problematic and excessive activities that do not involve the ingestion of a psychoactive substance cannot be deemed as legitimate behavioural addictions in the years to come (e.g., shopping addiction, sex addiction, work addiction, exercise addiction, etc.).

Gambling is a multifaceted rather than unitary phenomenon. Consequently, many factors are involved in the acquisition, development and maintenance of gambling behaviour. Such factors include an individual’s biological and genetic predisposition, their social environment, psychological variables (personality characteristics, attitudes, expectations, beliefs, etc.), macro-situational characteristics (how much gambling is marketed and advertised, the number of gambling venues within a jurisdiction, where the gambling venue is located), micro-situational characteristics of the gambling environment (on-site cash machine, provision of free alcohol, floor layout etc.), and the structural characteristics of the gambling activity itself (jackpot size, stake size, the number of times a individual can gamble in a given time frame, etc.). Most research has tended to concentrate on individual characteristics (personality, genetics, family and peer influence) rather than situational and structural characteristics.

The introduction of national lotteries, the proliferation of slot machines, the expansion of casinos, and the introduction of new media in which to gamble (e.g., Internet gambling, mobile phone gambling, interactive television gambling, gambling via social networking sites), has greatly increased the accessibility and popularity of gambling worldwide, and as a result, the number of people seeking assistance for gambling-related problems. In addition, the rise of remote gambling via the internet and mobile phones has arguably changed the psychosocial nature of gambling. I have also published a number of studies showing that to vulnerable and susceptible individuals (e.g., problem gamblers, minors, the intoxicated, etc.), the medium of the internet may facilitate and fuel problematic and addictive behaviours.

There are many known factors that make online activity potentially problematic to a minority of individuals. This includes factors such as easy accessibility, affordability, anonymity, convenience, escape, and disinhibition. Some of these factors can change the psychological experience of gambling. For instance, gambling with virtual representations of money online lower the psychological value of the money and people tend to spend more with virtual representations of money than if they were gambling with physical money. Also, when people lose money online it is a different psychological experience because no-one can see anyone losing face-to-face. As a result, there is less guilt and embarrassment about losing and vulnerable individuals may be tempted to spend more time and money than they had originally intended.

One very salient trend that has implications for gambling (and arguably problem gambling) is that technology hardware is becoming increasingly convergent (e.g., internet access via smartphones and interactive television) and there is increasing multi-media integration such as gambling and video gaming via social networking sites. As a consequence, people of all ages are spending more time interacting with technology in the form of internet use, playing videogames, watching interactive television, mobile phone use, social networking, etc. In addition to convergent hardware, there is also convergent content. This includes some forms of gambling including video game elements, video games including gambling elements, online penny auctions that have gambling elements, and television programming with gambling-like elements.

One of the key drivers behind the increased numbers of people gambling online and using social networking sites is the rise of mobile gambling and gaming. Compared to internet gambling, mobile gambling is still a relatively untapped area but the functional capabilities of mobile phones and other mobile devices are improving all the time. There are now hundreds of gambling companies that provide casino-style games to be downloaded onto the gambler’s smartphone or mobile device (e.g., tablet or laptop). This will have implications for the psychosocial impact of gambling and will need monitoring. Like online gambling, mobile gaming has the capacity to completely change the way people think about gambling and betting. Mobile phones provide the convenience of making bets or gambling from wherever the person is, even if they are on the move.

One of the most noticeable changes in gambling over the last few years – and inextricably linked to the rise of mobile gaming – has been the large increase of in-play sports betting. Gamblers can now typically bet on over 60 ‘in-play’ markets while watching a sports event (such as a soccer match). For instance, during a soccer game, gamblers can bet on who is going to score the first goal, what the score will be after 30 minutes of play, how many yellow cards will be given during them game and/or in what minute of the second half will the first free kick be awarded. Live betting is going to become a critical activity in the success of the future online and mobile gambling markets.

The most salient implication of ‘in-play’ sports betting is that it has taken what was traditionally a discontinuous form of gambling – where an individual makes one bet every Saturday on the result of the game – to one where an individual can gamble again and again and again. Gaming operators have quickly capitalized on the increasing amount of televised sport. In contemporary society, where there is a live sporting event, there will always be a betting consumer. ‘In-play’ betting companies have both catered for the natural betting demand but introduced new gamblers in the process. If the reward for gambling only happens once or twice a week, it is completely impossible to develop problems and/or become addicted. ‘In-play’ has changed that because there are soccer matches on almost every day of the week making a daily two-hour plus period of betting seven days a week.

New technologies in the form of behavioural tracking have helped online gambling companies keep track of players by noting (among many other things) what games they are playing, the time spent playing, the denomination of the gambles made, and their wins and losses. Although such technologies can potentially be used to exploit gamblers (e.g., targeting the heaviest spenders with direct marketing promotions to gamble even more), such technologies can also be used to help gamblers that may have difficulties stopping and/or limiting their gambling behaviour. Over the past few years, innovative social responsibility tools that track player behaviour with the aim of preventing problem gambling have been developed. These new tools are providing insights about problematic gambling behaviour. A number of European jurisdictions (such as Germany and The Netherlands) are now considering whether such tools should be mandatory for gaming operators to use especially as such tools are already being used in Sweden, Norway, Finland and Austria.

Although gamblers are ultimately responsible for their own behaviour, gambling can be minimised via both governmental policy initiatives (age restrictions, marketing and advertising restrictions, no gaming licenses unless operators display the highest standards of social responsibility to their clientele, etc.) and gaming operator initiatives (self-exclusion programs, information about games so gamblers can make informed choices, limit-setting tools that allow gamblers to set time and money loss limits, staff training on responsible gambling, referral to gambling treatment providers, etc.). Problem gambling can never be totally eliminated but harm minimisation practices can be put in place to keep the problem to a minimum. Treatment for gambling addiction should be free and paid for by gambling industry profits (either in the form of voluntary donations to a charitable trust or – if that doesn’t work – a statutory levy). In short, any jurisdiction that has legalised and liberalised gambling has a duty of care to put a national social responsibility infrastructure in place to prevent, minimise, and treat problem gambling as they would with any other consumptive and potentially addictive behaviour (e.g., drinking alcohol, smoking cigarettes, etc.)

Prophet share: A case study of ‘addiction to fortune telling’

In the latest issue of the Journal of Behavioral Addictions, there are two papers that I co-authored on muscle dysmorphia as an addiction (see ‘Further reading’ below). The reason I mention this is because in the same issue there was a case study report by Dr. Marie Grall-Bronnec and her colleagues of a woman (Helen) that was ‘addicted’ to fortune tellers. As noted in their paper:

“Clairvoyance consulting, also known as fortune teller consulting, is a behavior that may seem harmless, but can also become excessive. Fortune telling is defined as the practice of predicting information about a person’s life, using for example…astrology, cartomancy or crystallomancy”.

As I have noted in a number of my previous blogs, I subscribe to the view that if there are clinical criteria for addiction and a behaviour fulfils the criteria, it should be classed as an addiction (irrespective of the behaviour). This has led to accusations of me “watering down the concept of addiction” because such criteria have been applied to behaviours as diverse as gardening and chewing gum. According to the authors of the ‘fortune telling addiction’ paper:

“Helen is a 45-year-old woman who declares early on suffering from ‘a clairvoyance addiction’…She has no particular medical history, except for two major depression episodes after romantic breakups, and does not take any medication. She regularly sees a psychiatrist for support psychotherapy because of negative life events (sexual abuse and death in her family). She is divorced and does not have any children. Her career as a manager seems to fully satisfy her. She decides to seek treatment on account of her excessive financial expenditures due to the consultation of fortune tellers. Another motivation that explains her decision is her age. Indeed, she says she is entering a new phase in her life, after renouncing to the idea of becoming a mother one day”.

According to the paper, Helen had been consulting fortune tellers since she was 19 years old. She started using such people for educational and career advice as she claimed that she was poor at reaching important decisions herself and thought the life choices she made would be wrong. The authors noted that her first meeting with a clairvoyant was an event that gave her a feeling of reassurance. In her mid-twenties, her visits to clairvoyants escalated significantly and ended up losing control of her use of fortune telling”. At that particular time, she was visiting clairvoyants to get relationship advice from them (e.g., “Does he really love me?” and “How long will our relationship last?”). Her current ‘addiction to clairvoyants’ dates back to her mid- to late-30s when she got divorced after the failure of her marriage:

“She repeatedly returned to fortune telling to reassure herself about the future of her relationship, and increasingly so as it deteriorated. The breakup worsened the disorder. Since her divorce, she consults fortune tellers – not always the same person – on the phone or online, in a compulsive way, more and more often (up to every day), for longer and longer periods of time (up to 8 hours a day) and spends each time more and more money (up to 200 euros per session). As she is never satisfied with the fortune tellers’ predictions, she will consult again very soon after the latest call or connection. Every choice she has to make, from the most trivial (going to the movies) to the most important (making relationship decisions), leads her to irrationally consult a fortune teller”

Before each consultation she said he got very excited at the prospect and that the experience relieved all of her psychological discomfort (at least in the short-term). However, not long after consultations she would feel incredibly guilty. The paper also reported that during consultations with the fortune tellers, she was totally convinced that they could see her future and that their predictions would come true. He authors went on to report:

“This excessive behavior gives her some kind of reassurance and allows her to make up for her lack of self-confidence. In that sense, the excessive behavior could be considered as an attempt at self-medication or as a way to cope with negative emotions. However, Helen knows that her belief in the fortune tellers’ ability to predict the future is completely irrational. This brings major adverse consequences, particularly in financial terms: despite a comfortable income, she is indebted. She also says having low self-esteem, due to her in- ability to resist her strong urge to consult fortune tellers, and due to her being isolated from the others because of the time spent consulting fortune tellers. Helen succeeds in limiting the consultation of fortune tellers during short periods of time, when her financial situation becomes too critical”.

The authors of the report also used different sets of addiction criteria to determine whether Helen was truly addicted to consulting clairvoyants. They also used my own six criteria (salience, mood modification, tolerance, withdrawal, conflict, and relapse). Here are the authors own description of the behaviour using my components model:

  • Salience: “Consulting fortune tellers becomes the most important activity in Helen’s life and dominates her thinking (preoccupation and cognitive distortions), feelings (cravings) and behavior (she has progressively quit all her leisure activities, particularly going out with friends)”.
  • Mood modification: “Helen says feeling excitement before each consultation, but also feels nervous tension and anxiety. This excessive behavior gives her some kind of reassurance and the excessive behavior could be considered as an attempt at self-medication or a way to cope with negative emotions”.
  • Tolerance: “Over time, Helen has been feeling a growing need to consult fortune tellers, and the consultations have to last longer to obtain the same effect of relief”.
  • Withdrawal: “When she attempts to resist the urge to consult or has to refrain from consulting fortune tellers (in the case of her financial situation being too critical, for example), she feels tense and nervous”.
  • Conflict: “Helen knows that her use of fortune telling is problematic, and that it brings very negative consequences. However, she cannot refrain from consulting fortune tellers, leading to an intra-psychic conflict and guilt”.
  • Relapse: “Over the years, Helen has made repeated efforts to reduce and stop this problematic behavior. Her clinical course is characterized by relapses and remissions”.

Based on the evidence presented, there is clear evidence that Helen’s behaviour was problematic. Whether it was genuinely addictive is debatable but the authors provided some evidence that (in this case at least) the behaviour appeared to include some addictive aspects. The authors conclude that in addition to individual risk factors, other situational and structural characteristics may have played a role in the development of problematic behaviour concerning Helen’s ‘addiction’:

Regarding the risk factors related to the object of addiction (i.e. fortune telling use), one might mention, inter alia, the possibility to consult online, which guarantees anonymity. Furthermore, the Internet increases both accessibility and availability. Finally, the money spent during fortune telling sessions seems virtual, which makes it all the more easy to spend. Increased risks related to the Internet have already been described on gambling (Griffiths, Wardle, Orford, Sproston & Erens, 2009). Regarding socio-environmental risk factors, today’s society encourages the need for control and does not give way to uncertainty. In Helen’s case, all the conditions were met for the fortune telling use to become excessive, and we are tempted to conclude that it is an addictive-like phenomenon”.

Coming a part of the themes: The psychology of familiarity in gambling

Have you seen slot machines featuring Spiderman? Or the ones based on the Monopoly board game? Or the slots that have pictures of Lara Croft from the Tomb Raider video game? Most gaming operators will appreciate that all of these images have a strong brand presence, and that it is one of the main reasons for themed games. However, a more basic marketing tactic is being used here – the psychology of familiarity. This is used throughout the gaming industry but is most common on slot machines, online games, and scratchcards. For instance, Camelot’s scratchcards in the UK have featured film tie-ins (e.g., James Bond, Pirates of the Caribbean, Star Wars), and popular games (e.g., Connect Four).

But this wasn’t always the case. Back in the late 1980s I did some research on the names that gaming designers and operators gave their slot machines. One of the more interesting findings I reported in one of my academic papers was that over 50% of all machine names that I came across in amusement arcades had some reference to money on them (such as ‘Cashpoint’, ‘Cashline’, ‘Action Bank’, Piggy Bank’, ‘Money Belt’ etc.). Psychologically, all of these machine names gave the impression that this was where a player could get money from – not where they would lose it! Other categories of machine names included those with some reference to skill on them (‘Fruitskill’, ‘Skillchance’) suggesting that machine playing was a skillful activity and that gamblers could perhaps beat the machine. Other machines had what I called “acoustically attractive” names (Nifty Fifty, Naughty But Nice) or puns (Reel Fun, Reel Money). Since making these observations, I have always been interested in the subtle techniques that the gaming industry uses in getting the punter to play on their products. The psychology of gambling – or rather the psychology of gambling marketing – has come a long way in the last decade.

As I’ve already said, one of the techniques that the gaming industry uses (whether they realise it or not) is the psychology of familiarity. Gaming operators and marketers have realised that one weapon in their marketing armory is to design products which appear familiar before a player has ever even played on them – something that can partly be achieved through the name or theme of the slot machine. The examples I gave above showed that the names of slot machines appear to be important in impression formation. It is highly unlikely that the names of slot machines have any influence on gambling behaviour per se. However, when tied in with recent research on the psychology of familiarity, the names of machines do seem to be critically important – particularly in terms of gambling acquisition (that is, getting people to gamble in the first place).

Nowadays, slot machines are often named after a famous person (the Elvis Presley machines appear very popular in one of my local casinos), place, event, video game, board game, television show or film. Not only is this something that is familiar to the gambler but may also be something that the potential gamblers might like or affiliate themselves with (such as James Bond). This is different from a simple naming effect in that the machine’s theme may encompass the whole play of the machine, including its features, the sound effects (e.g., the theme tune to popular television programmes like Coronation Street or Eastenders), and light/colour effects. By using well-known and common themes, gamblers may be more likely to spend time and money playing them.

Some of the most popular UK slot machines are those that feature The Simpsons. There are many possible reasons why a gambler might be more likely to play on a Simpsons’ machine. The Simpsons have mass appeal and popularity across all ages and across gender. The machines are celebrity-endorsed and players may place trust in a ‘quality’ brand like The Simpsons. Gamblers may also hope that knowledge of the characters will help in the playing of the game. On a basic level, it might simply be that the game play of The Simpsons is more exciting, and that the sound effects and features are novel, cute and/or more humorous than other machines. There are many cases similar to this one where it could be speculated that the slot machine becomes so much more inducing because it represents something that is familiar and/or special to the gambler.

Familiarity is a very important psychological aspect of why themed slot machines have been more prominent over the last decade. Familiar themes have the capacity to induce a ‘psycho-structural interaction’ between the gambler and the gambling activity. This is where the gambler’s own psychology interacts with the machine’s structural characteristics and produces different consequences for each person depending upon what the feature means to them personally. If the themes are increasingly familiar, a gambler might be more likely to persevere with the complexities of a machine. Gamblers may find it more enjoyable because they can easily interact with recognizable images they experience. Therefore, the use of familiar themes may have a very persuasive effect, leading to an increase in the number of people using them, and the money they spend. Whilst there are many other aspects that influence an individual’s decision to gamble, the possible persuasive nature of the themes should not be underestimated.

As you may have already gathered, there is a strong overlap between the psychology of familiarity, branding, and the psychology of persuasion. In very simple terms, a gambler must be exposed to the product and be aware of its presence before they can even make the decision to gamble. This is relatively easy to achieve given the ubiquity of slot machines and the fact that current machines will use any number of techniques to grab a potential player’s attention. These include television or film theme tunes, bright flashing lights, and/or pictures or voices of celebrities. Once a gambler’s attention has been gained, the product must be likeable and familiar enough for them to think about gambling and wanting to interact with the machine further. Immediately familiar images and sounds are likely to lead to a much quicker decision to gamble. All which goes to show – the gaming industry knows what it is doing!

Sound ideas: A brief look at the effect of music on gambling behaviour

Throughout my academic career, I have always been interested in how the design of environments affects human behaviour. Given that my primary research area is the psychology of gambling and that my most passionate hobby is listening to music, it probably won’t come as a surprise that I have carried out research into the effect of music on gambling behaviour.

The effect of music has been studied extensively in commercial contexts (particularly advertising and retailing). Many research studies have shown that music has the capacity to affect consumers’ perceptions of a particular environment, their intended and actual purchase behaviour, and time spent in a particular environment. Advertisers and marketers use such knowledge to help target their consumer group. Psychologists Adrian North and David Hargreaves have noted in many of their papers that music may have the capacity to modify psychological arousal or induce relaxation. A number of studies have supported this claim through various investigations into the arousal of music.

Highly arousing music has been characterised as loud, unpredictable and with a quick tempo. Low arousing music in contrast is soft, predictable, and has a slower tempo. The more the music is able to produce arousal in individuals, the more pleasurable it is for them, and the more likely it will be their preference. Musical tempo is another area within the field of music that has generated empirical research. A variety of reports from participants and consumers have described fast tempo music with a variety of adjectives, indicating it as happier, pleasant, joyous, exhilarating. Studies manipulating the tempo of music have found that faster music leads to more positive judgements of advertisements, enhances effects on the performance of tasks, leads to faster movement, and higher arousal levels. Slow music has the opposite effects resulting in more relaxing, solemn adjectives being used when participants described it.

As both a structural and situational characteristic in gambling behaviour, the role of music has become more apparent in the last decade. Many slot machines now have musical interludes. This makes them generally more appealing, especially if they are familiar. Researchers (including myself) have consistently argued that sound effects can contribute to the encouragement of gambling.

Back in 2003, Dr. Jonathan Parke and myself published a book chapter examining the environmental psychology of gambling in the book Gambling: Who Wins? Who Loses? (edited by the sociologist Gerda Reith). A small part of that review speculatively examined the role of music in facilitating gambling behaviour. We noted that at the time we wrote the review, no research has been carried out on the topic (and that research was obviously needed). A couple of years later, we published a paper in the Journal of Gambling Issues and reported a number of observations based on our experiences of enaging in participant and non-participant observation in amusement arcades and other gambling venues.

We argued that auditory effects have the capacity to make a slot machine more ”aesthetically appealing” to individuals and this differentiation could be a deciding factor when choosing a machine. We also hypothesized that music has the potential to facilitate, stimulate, maintain and exacerbate gambling behaviour in some individuals. This could be due to the fact that familiar music may induce a feeling of enjoyment as it is recognisable to the individual and thus may entice them into playing (something that I had noted in an earlier paper that I wrote with David Dunbar in a 1997 issue of the Society for the Study of Gambling Newsletter). The music played when one wins is distinctive and memorable and could also lead to further plays. In short, music has the capability to increase confidence, modulate arousal and relaxation and help the player to disregard previous losses.

In 2007, I published a study in the journal International Gambling Studies that I carried out with Laura Dixon and Dr. Richard Trigg investigating the role of music in gambling behaviour. In our experiment, 60 participants played virtual roulette in one of three conditions.The three conditions were (i) no music, (ii) slow tempo music,and (iii) fast music (20 participants in each condition). Tengames of roulette were played with speed of betting, amountspent across high, medium and low-level risk bets and totalamount spent recorded. Their results showed that speed ofbetting was influenced by musical tempo with faster bettingoccurring while listening to higher tempo music.However, there was no relationship between musical tempo and either the size of the bet or the overall amountspent. Although not carried out in a casino, we believed our findingsprovided valuable insight into how background music can bemanipulated to increase the speed of gambling.

In 2010, along with Jenny Spenwyn and Dr. Doug Barrett, I published another study examining the effect of music on gambling in the International Journal of Mental Health and Addiction. This study (as far as we are aware) was the first ever empirical study to examine the combined effects of both music and light on gambling behaviour. While playing an online version of roulette, 56 participants took part in one of four experimental conditions (14 participants in each condition); (1) gambling with fast tempo music under normal (white) light, (2) gambling with fast tempo music under red light, (3) gambling with slow tempo music under normal (white) light, and (4) gambling with slow tempo music under red light. Risk (i.e., the amount of money spent) per spin and speed of bets were measured as indicators of gambling behaviour. We found significant effects for speed of bets in relation to musical tempo, but not light. We also found a significant interaction between light and music for speed of bets. In short, we found that fast tempo music under red light resulted in individuals gambling faster gambling.

Most recently, some of my research colleagues in Norway, led by Dr. Rune Mentzoni, published a paper in the Journal of Behavioral Addictions that also examined music’s effect of gambling behaviour. Like our studies, they carried out a laboratory experiment. Their study comprised101 undergraduate students who played a computerized gambling task inwhich either a high-tempo or a low-tempo musical soundtrack was present. It was reported that: low-tempo music was associated with increased gambling persistence in terms of overall number of bets placed, whereas high-tempo music was associated with intensified gambling in terms of faster reaction time per placed bet. Based on their results, they concluded that high-tempo music is associated with more risky gambling behaviour (by increasing gambling persistence and by reducing reaction time for bets placed).

From the empirical literature published so far, there does appear to be some evidence to suggest that the gambling environment may be manipulated by the use of sound of music (as well as other characteristics such as light and colour) and that such situational characteristics may affect gambling behaviour. However, the empirical base, is limited and further research is needed before reaching any definitive conclusions.

Within you, without you: Where does addiction reside?

In 1984, Dr. Milton Burglass and Dr. Howard Shaffer published a paper in the journal Addictive Behaviors and claimed that arguably the important questions in the addiction field are ‘why do people become addicted to some things and not others?’ and ‘why some people become addicted and not others?’ Answers to these questions have been hindered by two common misconceptions about addiction, which to some extent have underpinned the ‘hard core’ disease concept of addiction. These are that addiction somehow resides within: (i) particular types of people or (ii) particular substances, and/or particular kinds of activity. That is, either some people are already ‘diseased,’ or else some substances/ activities cause this disease, or both.

There is a belief that some people are destined to become addicted. Typically this is explained in one (or both) of two ways. That some people (i.e., ‘addicts’) have an addictive personality, and that there is a genetic basis for addiction. The evidence for ‘addictive personality’ rests to a certain extent upon one’s faith in the validity of psychometric testing. Setting aside this major hurdle, the evidence in this area (as I argued with my colleagues Dr. Michael Larkin and Dr. Richard Wood in a 2006 issue of Addiction Research and Theory [ART]) is still inconclusive and contradictory.

First, psychologists have yet to determine which particular personality traits are linked to addiction. Studies have claimed that ‘the addictive personality’ may be characterized by a wide range of factors (e.g., sensation-seeking, novelty-seeking, extroversion, locus-of-control preferences, major traumatic life events, learned behaviours, etc.). The extent of this range stretches not only the notion of an ‘addictive personality’ but also the concept of ‘personality’ itself. Inevitably, much of this work relies on correlation analysis, and so the interpretation of results is not easily framed in terms of cause and effect. The approach is overly simplistic and is underpinned by a simple proposition that if we can divide people up into the right groups, then the explanation will emerge. However, addiction is far more complex than this. Of course, the relationship between individual bodies, minds, contexts, and life histories is complex and important – but it requires that we approach the matter from a more sophisticated and integrative position.

The search for a genetic basis for addiction rests upon the notion that some types of individuals are somehow ‘biologically wired’ to become addicts. In our 2006 ART paper, we argued that we must set aside any doubts about the limited conceptualization of ‘the environment’ that often typifies this kind of research, and its combination with epidemiological designs that are largely descriptive. Meta-analytic reviews have concluded that the heritability of addictive behaviour is likely to be controlled by many genes each contributing a small fraction of the overall risk. Furthermore, some of these same genes appear to be risk factors for other problems, some of them conceptually unrelated to addiction. We argued that the main point here is that while these findings do contribute something to our understanding of ‘why some people and not others,’ they do not adequately or independently explain the range of variation. Therefore the most we can say is that some people are more likely to develop problems under certain conditions, and that given the right conditions most people could probably develop an addiction. Emphasis needs to be placed on identifying those ‘conditions,’ rather than on searching for the narrowest of reductionist explanations.

We also argued in our 2006 ART paper that substances and activities cannot be described as intrinsically addictive in themselves (unless one chooses to define ‘addictive’ in terms of a substance or behaviour’s ability to produce tolerance and/or withdrawal, and to ignore the range of human experience that is excluded by this). Biologists may be able to tell us very valuable things about the psychopharmacological nature of the rewards that particular substances and behaviours provide, and the different kinds of neuroadaptation that they may or may not produce in order to effect tolerance and/or withdrawal. But we argue that this on its own, is not an adequate explanation for addiction. In 1975, Dr. Lee Robins’ classic study (in the Archives of General Psychiatry) of heroin-users returning from the Vietnam war is one example of the evidence that refutes this oversimplification. This study clearly highlighted the importance of context (i.e., that in a war zone environment individuals were addicted to heroin but on return to civilian life the addiction ceased to exist), and the framework provided by such contexts for making sense of addiction. In a hostile and threatening environment, opiates clearly provided something not usually required by most people; and given a cultural environment in which opiate use is a commonplace, and opiates are available, then opiate use ‘makes sense’. This study provides support for the assertion that some people are more likely to become addicted under some conditions, and that given the right conditions perhaps many people could understand what it means to be an addict.

So, with regard to the question, ‘why some individuals/addictions and not others?’ the rewards associated with various activities may be qualitatively very different, and may not necessarily be inherent or unique to a particular activity or substance, either. Many rewarding activities are rewarding because they present individuals with opportunities to ‘shift’ their own subjective experience of themselves (for example, see the research on Ecstasy use and bungee jumping that I published with Dr. Michael Larkin in a 2004 issue of the Journal of Community and Applied Social Psychology).

Frequently, a range of such opportunities is offered to the experienced user. Dr. Howard Shaffer (in a 1996 paper in the Journal of Gambling Studies) has pointed out that those activities that can be most relied upon to shift self-experience in a robust manner are likely to be the most popular – and (as a consequence) to be the most frequent basis of problems. So, obviously, our understanding of the available resources for mood modification must play a major part in understanding addiction. However, we must make a careful distinction between describing some substances as being more ‘robust shifters of experience’ than others (as we advocated in our 2006 ART paper) and describing some substances as ‘more addictive’ than others (which we argued against).

A toning for reward and punishment: A brief look at the impact of colour on gambling behaviour

Researchers and those working in the gambling industry have been interested in the factors that lead to the acquisition, development and maintenance of gambling. Aside from individual differences, the combination of the situational characteristics of the environment, and the structural characteristics of the actual game being played have been highlighted as critical ingredients in determining these behaviours in relation to gambling. This idea parallels with that of store designers who manipulate various features of the environment in shops to encourage purchase behaviour in consumers.

Situational characteristics are typically those features of the environment that may encourage people to gamble in the first place, and in some cases to keep on gambling. Examples of such characteristics could include accessibility (e.g., the number of outlets or opportunities to gamble, membership rules); sensory factors (e.g., atmospherics, light, colour and sound effects); the use of advertising; access to other things (e.g., cash machines, alcohol, food); physical comfort (e.g., seating, temperature); and social facilitation (the presence or absence of other people in the vicinity). These are often acquisition factors and are often important in the initial decision for an individual to gamble. Structural characteristics are features of the game itself that can contribute to the development and maintenance of gambling behaviour. These can be reinforcing to the player as they offer constant rewards. For instance, the ‘aura’ of a slot machine may offer excitement, arousal and tension in terms of its high event frequency, near misses, stake size, and the use of music, lights and colour.

One characteristic that can impact on both a situational and structural level in gambling is colour. For instance, this can be manipulated and/or adapted in terms of the design of a slot machine or scratchcard, an Internet gambling website, or the décor and ambience of a gambling environment. Research more specifically into the psychology of colour has been somewhat controversial in how it affects individual emotions. The majority of literature in the colour psychology field has come from advertising and marketing papers. This is because they are interested in colour selection in the way that it may facilitate the sale of their products. It has been speculated that learning about consumers’ emotional reactions to colour can be a useful predictor of purchase behaviour. This is because certain colours can provoke a particular positive or negative reaction. For instance, red has consistently been found to be stronger, more exciting, and more arousing than blue. This concept has been applied in a variety of situations in an attempt to manipulate people’s behaviours. However, a lot of this evidence is anecdotal, as it is not based on any sort of controlled experimental design.

Colour preference has been explained in terms of cultural significance and associative learning. It has been suggested that associations of colour that have been developed in the past have been forwarded as explanations of perceptions of colour today. For example, blue has been associated with night, dark and quiet. Warm colours, such as red, are used in order to attempt to arouse consumers such as in gambling environments. Across cultures, red has predominantly been found to be the most effective in influencing human emotions. Individual responses to colour have also been explained in relation to the arousal that they produce. It has been suggested that colours that are on the extreme ends of the colour spectrum (e.g., red and violet) generate greater arousal than those in-between. However, when red and blue have been compared in terms of their influences on arousal, differences have been found between them, with red producing greater cortical arousal.

With regards to the gambling literature in this field there has been minimal research conducted looking at the impact of colour on gambling. In an observational  study I published with Helen Swift back in 1992, we reported our findings about various situational characteristics of five English amusement arcades. We noted that the interiors were generally red or towards the red end of the colour spectrum. This observation appears to suggest that gaming venue designers make use of the principle of red light exciting whilst gambling. Light and colour effects have developed in their sophistication over recent years and the gaming and casino industry have taken advantage of this when designing machines, games, and gaming venue interiors.

An old 1982 study by Graham Stark and colleagues in the journal Current Psychological Research provides one of the few empirical contributions assessing the effects of coloured light on gambling behaviour. Their study found that compared to gambling under blue light, gambling under red light leads to more risks taken, higher stakes made, and more frequent bets. They suggested that because blue is less arousing it leads to slower performance, as their attention is not specially focused on the task. As red was highly arousing it caused participants to focus on the salient aspects resulting in faster bets. The arousing effects of red were speculated to increase overt behaviour.

Similar types of research study have also been carried out on computer gaming. For instance, a study led by Dr. Sandy Wolfson in a 2000 issue of Interacting With Computers examined the effects of music and lighting on computer game play. It was found that red lighting led to participants underperforming in the latter games played (compared to blue), although initially both groups improved continuously. The red group’s heart rate also decreased in line with their decline in performance. This was explained in terms of red initially being more arousing, which led to higher concentration and less error rates than blue, but as time went on they became desensitized to its arousal.

A more recent experimental investigation by Jenny Spenwyn, Dr. Doug Barrett and myself in a 2010 issue of the International Journal of Mental Health and Addiction reported what we believe was the first ever empirical study into the combined effects of both music and lighting colour on gambling behaviour. While playing an online version of roulette, participants took part in one of four experimental conditions; (1) gambling with fast tempo music under normal (white) light, (2) gambling with fast tempo music under red light, (3) gambling with slow tempo music under normal (white) light, and (4) gambling with slow tempo music under red light. We reported a significant interaction between light and music for betting speed, and that the speed at which participants gambled was increased while playing under red light and fast tempo music.

It is clear that situational characteristics of gambling environments (including colour) appear to have the potential to play a role in the acquisition, development and maintenance of gambling behaviour. The success of the gambling establishment’s situational and structural characteristics (where success is defined as an increase in gambling due to the situational or structural characteristic) depends upon the psycho-situational and/or psychostructural interaction. The importance of a characteristic approach to gambling is the possibility of pinpointing more accurately where an individual’s psychological constitution is influencing gambling behaviour. Such an approach also allows for psychologically context specific explanations of gambling behaviour rather than explanations that focus solely on personality and individual differences.

Design of the times: How does venue design influence gambling behaviour (revisited)?

In a previous blog I briefly examined how gaming venue design affects gambling behaviour, particularly in relation to casino atmospherics. Over the last century, the gaming industry has used various inducements and ploys to entice people to gamble. The psychology of marketing has become big business. Casinos – like any other business with a product to sell – has had to keep up with times and spend huge amounts of money in an effort to get even more of your money. As a psychologist, I have always been very interested in the design features of gambling venues. Put more simply, to what extent is psychology used in design features as a way of taking more money from you?

I have spent many years studying the situational characteristics of many gambling venues to examine this question. Situational characteristics are primarily features of the environment (such as the location of the casino, the number of casinos in a specified area, membership requirements, etc.) but can also include internal features of the casino itself (such as décor, heating, lighting). These features can be very important in both the initial decision to gamble and continued gambling once you are in the casino.

Most casinos around the world try to fill up as much floor space as they can with slot machines. This is because slots are the most profitable form of gambling for operators. The profitability of slot machines can depend on simple factors such as floor location, coin denomination and pay off schedules. Floor layout is also important in other areas. For instance, restaurants are often positioned in the centre or back of the casino so that customers have to pass the gaming areas before and after they have eaten. Another strategy is to use deliberate circuitous paths to keep customers in the casino longer, the psychology being that if the patrons are in the casino longer they will spend more money. In many US casinos the management will provide free alcoholic drinks – all in the hope that you may spend a little more while under the influence and being a little less rational!

Casino designers can also introduce environmental features to manipulate human senses. For instance, light and colour are two variables that can affect behaviour – and gambling is no exception. Psychological research has shown that colour can evoke affective states and influence behaviour. Some colours are associated with certain moods. Red is “exciting” and “stimulating”, blue is “comfortable”, “secure” and “soothing”, orange is “disturbing” and green is “leisurely”. Colour can affect physiological reactions such as blood pressure, breathing rate, mood and arousal. In gambling situations, research has shown that people will gamble and stake money more under red light than colours towards the blue end of the spectrum.

The use of sound can also be important. Constant noise and sound gives the impression of a noisy, fun and exciting environment. In addition, many slot machines play musical tunes or ring bells and buzzers if someone has won. As coins are paid out by dropping down onto a metal pay out tray (along with buzzers, bells and music), it gives the impression that winning is more common than losing – as you cannot hear the sound of losing! Music can also be used to manipulate how we feel. Two of the many effects music can have may be to heighten psychological arousal or to relax. Early studies showed that when customers in a supermarket were exposed to loud music, their shopping rate – how much they bought per minute spent in the store – was higher than when quiet music was played. Gamblers may also spend more under similar conditions although there have only been a handful of studies published to date. We have carried out a couple of experiments which have shown that gamblers play faster when there is music with a high beats per minute playing in the background.

Believe it or not – and as I pointed out in a previous blog – smell may also have an influence on gambling behaviour. Experiments carried out in Las Vegas casinos showed that a slot machine’s takings could be increased by spraying them with pleasant odours. Researchers found that the slot machines with pleasant aromas had significantly higher profits than the machines not sprayed with any odours. This is very similar to shops who pump the smell of chocolate in the run up to Valetine’s Day hoping it will increase sales.

Physical comfort is also an important factor. I call this the “seating, eating and heating” phenomenon. If a gambler is physically (as well as psychologically) comfortable, there is more chance they will stay in the casino. Comfort is therefore used by casino management to encourage and prolong gambling. For instance, taking a gambler off their feet enhances physical comfort considerably and reduces fatigue. Another obvious customer care tactic is the availability of refreshments and amenities (including toilets). Paradoxically, serious gamblers often gamble for long periods of time. Consequently, they are often reluctant to leave a slot machine or the roulette table to get a drink or food, or go to the toilet as they do not want to lose their “lucky seat” or favourite machine. Interestingly, in one research study, thirty bars with slot machines were compared with another thirty that didn’t. In the bars without slot machines, almost all of the clientele drank pints. However, in the bars with slot machines, only 8% of the clientele drank pints. The main reason for this was that slot machine players did not want to leave the machines to go to the toilet in case someone ‘stole’ their machine!
