Gambling addiction recall program

Postby Kagarr В» 17.08.2019

.

Gambling is a widespread form of entertainment that may afford unique insights into the interaction between cognition and emotion in human decision-making. It is also a behaviour that can become harmful, and potentially addictive, in a minority of individuals.

This article considers the status of two dominant approaches to gambling behaviour. The cognitive approach has identified a number of erroneous beliefs held by gamblers, which cause them to over-estimate their chances of winning. The psychobiological approach has examined case-control differences between groups of pathological gamblers and healthy controls, and has identified dysregulation of brain areas linked to reward and emotion, including the ventromedial prefrontal cortex vmPFC and striatum, as well as alterations in dopamine neurotransmission.

In integrating these two approaches, recent data are discussed that reveal anomalous recruitment of the brain reward system including the vmPFC and ventral striatum during two common cognitive distortions in gambling games: the near-miss effect and the effect of personal control. In games of chance, near-misses and the presence of control have no objective influence on the likelihood of winning.

These manipulations appear to harness a reward system that evolved to learn skill-oriented behaviours, and by modulating activity in this system, these cognitive distortions may promote continued, and potentially excessive, gambling. The term gambling refers to a form of entertainment where a wager, typically a sum of money, is placed on the uncertain prospect of a larger monetary outcome.

The British Gambling Prevalence Survey found that 68 per cent of respondents reported gambling at least once in the past year, and 48 per cent reported gambling on games other than the state lottery Wardle et al. This refers to the fact that gambling odds are carefully arranged to ensure a steady profit for the bookmaker, casino or slot machine; something that can only be achieved at the expense of the gambler.

In economic terms, the expected value of gambling is negative, such that an accumulating debt is inevitable over a large number of trials. Thus, the widespread tendency to accept such gambles may provide some useful insights into the mechanisms of human irrationality. However, in addition to the financial considerations, it is probable that gambling is also motivated by cognitive and emotional factors.

Unpredictable monetary wins are a potent form of positive reinforcement that strengthen the instrumental response. Environmental cues e. Gambling may also serve to alleviate unpleasant states of boredom, anxiety or low mood i. Gambling is also a behaviour that can spiral out of control in some individuals. As gambling becomes excessive, there are observable harms including debt, illegal activity and interpersonal conflict.

In its most extreme form, pathological gambling is a recognized psychiatric diagnosis in the Diagnostic and statistical manual , version 4 text revision DSM-IV-TR; American Psychiatric Association , with a prevalence of around 1 per cent Petry et al. The US prevalence of problem gambling is estimated between 1 and 4 per cent Shaffer et al. Accumulating data point to a re-alignment of pathological gambling within the addictions Potenza The diagnostic criteria themselves were closely modelled on the features of substance dependence, and there is evidence of cravings Tavares et al.

In addition to clinical phenomenology, several other lines of evidence indicate aetiological overlap between problem gambling and drug addiction: there is substantial comorbidity between the conditions Petry et al. The critical difference is that problem gambling does not involve the ingestion of a psychoactive substance. Long-term drug administration causes an array of changes in the brain, so that in current users, it is difficult to disentangle the mechanisms by which the addiction developed.

Research into gambling behaviour can therefore address two broad issues. First, given the general prevalence of this behaviour, what does gambling tell us about the fallibility of decision-making mechanisms in the healthy human brain?

Second, from a clinical perspective, how does this common recreational behaviour become dysfunctional? An overarching theory of gambling should be able to explain both its general popularity, and its potential to become pathological. The aim of the present article is to integrate two approaches to gambling behaviour that have gained considerable popularity in recent years, but which are rarely linked and command quite separate research literatures. The cognitive approach emphasizes thought content and a distorted appraisal of control during gambling.

The psychobiological approach assumes a disease model of problem gambling, and has sought to identify group differences between pathological gamblers and healthy controls on measures of brain chemistry and brain function. I will provide an overview of the current status of each approach, before reviewing recent findings that suggest a synthesis of the two approaches may be warranted.

Several kinds of erroneous beliefs have been identified Toneatto et al. In believing that they are acquiring the necessary skills to win or even that such skills exist in principle , the gambler is able to justify continued play. In this paradigm, the gambler is asked to verbalize all thoughts during a brief period of gambling in a naturalistic setting, such as a casino. They are encouraged to speak continuously and to avoid censoring their speech. Their speech output is recorded by the experimenter, and statements are categorized subsequently as accurate e.

High rates of erroneous thoughts were even present in players who were clearly aware that the outcomes were determined by chance, given their responses on a questionnaire administered before and after the gambling session. A number of studies support this Walker ; Griffiths ; Baboushkin et al. Using the think-aloud procedure, Griffiths found that regular at least once per week fruit machine players reported more erroneous thoughts than non-regular players less than once per month.

Baboushkin et al. In addition, a programme of research by Ladouceur et al. At a psychological level, it is important to understand how these faulty beliefs develop, in both occasional and problem gamblers.

There appear to be at least two mechanisms at work. On the one hand, humans are generally poor at processing probability and judging randomness. On the other hand, various features of gambling games directly foster these distorted beliefs. It is widely accepted that humans are highly error-prone at judging probabilities Gigerenzer Subjects prefer sequences without long runs of the same outcome, and with balanced overall frequencies of heads and tails.

This may arise because subjects fail to appreciate the independence of turns, and expect small samples to be representative of the populations from which they are drawn Wagenaar In a study of university students choosing lottery tickets, it was shown that players preferred tickets of apparently random numbers over tickets containing consecutive numbers 14—19 , clusters of numbers e.

As a simple example, slot-machine wins are routinely accompanied by bright flashing lights and loud noises. By distorting their memory of past outcomes, this may bias the decision to continue play.

In the next sections, we focus on two further structural characteristics that appear to manipulate the player's perceptions of winning in a particularly profound manner. Personal control refers to the gambler's level of involvement in arranging their gamble. On a game of chance, the gambler is equally likely to win if they arrange their gamble, or if another agent places the gamble for them. However, it has been reliably observed across many forms of gambling that players have inflated confidence when they are given the opportunity to arrange the gamble themselves.

In a seminal study by Langer , subjects were invited to buy a lottery ticket, and the experimenter later asked to buy back their ticket. In a follow-up experiment, subjects who had chosen their ticket were more likely to refuse a swap for a ticket in a second lottery with a higher chance of winning.

This illustrates how perceived control can actually cause subjects to reject a genuine opportunity to increase their chances of winning. Similar findings have been reported in craps and roulette. They can place bets on certain numbers being rolled, on any player's throw including their own.

Regular craps players display a range of superstitious behaviours when throwing the dice, such as blowing on the dice, and using more force in their hand movements when trying to throw a high number Henslin Consistent with an effect of personal control, when it is a player's turn to shoot the dice, they are more likely to place a bet, place higher bets, and place more risky bets compared with when other players are shooting Davis et al. In each of these examples, the presence of personal control has no effect whatsoever on the likelihood of winning.

Near-misses occur when an unsuccessful outcome is proximal to a win. They occur across all forms of gambling, such as when a slot-machine payline displays two cherries with the third cherry just coming into view. Near-misses are salient events to the gambler.

Gamblers often interpret near-misses as evidence that they are mastering the game, and in this sense, near-misses appear to foster an illusion of control.

A number of research studies have investigated the behavioural effects of near-miss outcomes on gambling play. The reels contained red and green stimuli, and wins were awarded for three reds. One group of subjects played a game where the chances of a red icon appearing on reels 1—3 was 70, 50 and 30 per cent, and hence there was a high likelihood of a near-miss. A second group played the same game but with reels 1 and 3 reversed, so that it was evident early on that the trial was a loss.

The actual proportion of wins was matched across the two groups. Subjects in group 1 were seen to play for significantly longer than subjects in group 2. More recent studies have begun to systematically manipulate the frequencies of near-misses. Cote et al. Subjects in the near-miss condition played significantly more trials on the game. The cognitive approach argues that gambling behaviour is maintained by erroneous beliefs and cognitive distortions about the true chances of winning, such that gamblers perceive the expected value of gambling as positive, when in fact, the objective expected value is negative.

Nevertheless, the cognitive approach has considerable explanatory power: this framework can capably explain the general prevalence of gambling as erroneous cognitions and inaccurate perceptions of randomness are common in infrequent gamblers. The cognitive framework can also explain the process by which gambling becomes pathological as problem gamblers are hypothesized to make more erroneous cognitions or to have greater conviction in those beliefs, or to be more inclined to use their faulty beliefs to justify continued gambling.

There is some evidence for this hypothesis using the think-aloud procedure Walker ; Griffiths ; Baboushkin et al. The psychobiological approach attempts to identify differences in aspects of brain function between groups of individuals with and without gambling problems.

Studies can be divided into those measuring neurotransmitter function, and those measuring the activity or integrity of different brain areas. The latter approach can be subdivided into neuropsychological studies, which measure brain function indirectly using tasks validated in patients with brain injury, and functional imaging studies, which measure brain activity directly during task performance, typically with functional magnetic resonance imaging fMRI.

Studies of neurotransmitter function in gamblers have focussed on the monoamines, dopamine, serotonin and noradrenaline, which are known to play key roles in arousal, motivation and higher cognitive functions see Robbins for a review.

It is difficult to measure neurotransmitter levels directly in the human brain. Instead, a number of studies have measured peripheral markers in urine, plasma or cerebrospinal fluid CSF. These studies reported increases in markers of noradrenaline function Roy et al. The study by Bergh et al. The study by Meyer et al. Problem gamblers showed greater increases in both noradrenaline and dopamine levels during casino gambling for real money, compared with a laboratory gambling session for points reward.

Thus, the direction of effect—for dopamine changes in particular—remains unclear, and findings from peripheral markers must be treated with caution as their relationship with central activity is complex.

Another indirect approach has been to study genetic variants that are thought to affect neurotransmitter function. For example, the dopamine D2 receptor gene displays a common polymorphism TaqIA, occurring in A1 and A2 alleles that influences D2 receptor density in the brain, and is linked to the prevalence of alcohol and stimulant addictions Noble Studies by Comings et al. The reported TaqIA association increased prevalence of the A1 allele is consistent with reduced D2 receptor binding in the striatum in pathological gamblers Pohjalainen et al.

Genetic studies have also indicated effects on other genotypes affecting serotonin and noradrenaline function Comings et al.
