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.

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.
