Erroneous gambling-related beliefs emerge from broader beliefs during problem-solving: a critical review and classification scheme

Impulse and reason? Justifications in problem gambling

People often use justifications to make desirable choices, but little is known about these justificatory thoughts in gambling. We conducted an exploratory Study 1 (n = 101) and a confirmatory Study 2 (n = 154) using online surveys, recruiting gamblers with prior and current experience of trying to reduce their gambling. Using justifications recognized in the domains of eating and consumer behavior (e.g., prior use of effort, feelings of achievement), we examined whether justifications were associated with problem gambling severity, and whether they explained additional variance above trait impulsivity and cognitive distortions. In both studies, justifications were positively associated with problem gambling severity, after accounting for trait impulsivity and cognitive distortions. Additionally, justifications were positively correlated with trait urgency and cognitive distortions, indicating that such thinking may not be antithetical to impulsivity. These data provide proof-of-principle evidence that justificatory thinking occurs in the context of gambling, is related to problem gambling severity, and may therefore represent a neglected aspect of gambling-related cognitions.

The complex nature of human operant gambling behaviour involving slot games: Structural characteristics, verbal rules and motivation

Gambling behaviour is likely to be strongly influenced by operant learning principles. Most forms of gambling, and most notably slot machine play, follow a random ratio (RR) schedule of reinforcement that should lead to rapid and extinction-resistant behaviour. In this paper we highlight the caveats that need to be applied when generalising animal models of learning to human behaviour. Studies need to be cognisant of the role of verbal rules and cognitive appraisals of contingency; the ability for participants to self-modify important elements of reward schedules; potential differences between concurrent and longitudinal schedule preferences; and, the role of important human motivations in financial decision-making. In particular, we believe that operant approaches to gambling may need to incorporate a greater focus on FOMO (or the fear of missing out) as a motivational construct that may explain some of the observed patterns of behaviour, including riskier behaviours, on slot games. The implications of these observations for future research and harm minimisation are discussed.

Gambling along the schizotypal spectrum: The associations between schizotypal personality, gambling-related cognitions, luck, and problem gambling

Objective

Schizotypal personality (schizotypy) is a cluster of traits in the general population, including alterations in belief formation that may underpin delusional thinking. The psychological processes described by schizotypy could also fuel cognitive distortions in the context of gambling. This study sought to characterize the relationships between schizotypy, gambling-related cognitive distortions, and levels of problem gambling.

Methods

Analyses were conducted on three groups, a student sample (n = 104) with minimal self-reported gambling involvement, a crowdsourced sample of regular gamblers (via MTurk; n = 277), and an additional crowdsourced sample with a range of gambling involvement (via MTurk; n = 144). Primary measures included the Schizotypal Personality Questionnaire - Brief (SPQ-B), the Peters et al. Delusions Inventory (PDI-21), the Gambling Related Cognitions Scale (GRCS), and the Problem Gambling Severity Index (PGSI). Luck was measured with either the Belief in Good Luck Scale (BIGLS) or the Beliefs Around Luck Scale (BALS).

Results

Small-to-moderate associations were detected between the components of schizotypy, including delusion proneness, and the gambling-related variables. Schizotypy was associated with the general belief in luck and bad luck, but not beliefs in good luck. A series of partial correlations demonstrated that when the GRCS was controlled for, the relationship between schizotypy and problem gambling was attenuated.

Conclusions

This study demonstrates that schizotypy is a small-to-moderate correlate of erroneous gambling beliefs and PG. These data help characterize clinical comorbidities between the schizotypal spectrum and problem gambling, and point to shared biases relating to belief formation and decision-making under chance.

Protective Action and Risky Beliefs: The Relationship Between Religion and Gambling Fallacies

A number of studies have explored the relationship between religious beliefs and gambling (including gambling fallacies and gambling harm) but report seemingly contradictory findings. While some studies have found religious belief to be positively associated with gambling fallacies, others have found it to be a protective factor from gambling harms. One explanation for these differing effects is that gambling fallacies and metaphysical religious belief share properties of supernatural and magical thinking. Nevertheless, social support and moral strictures associated with religion might help protect against an unhealthy engagement with gambling. Using a multidimensional measure of religiosity, we hypothesised that only the supernatural facet of religious adherence would present a risk for gambling fallacies. We analysed two archival data sources collected in Canada (Quinte Longitudinal Study: N = 4121, M_age = 46, SD_age = 14, Female = 54%; Leisure, Lifestyle and Lifecycle Project: N = 1372, M_age = 37, SD_age = 17, Female = 56%). Using the Rohrbaugh-Jessor Religiosity Scale, we confirmed that the supernatural theistic domain of religion was a positive risk factor for gambling fallacies. However, participation in ritual (behavioural) aspects, such as churchgoing, was negatively associated with risk, and no effect was observed for the consequential (moral) domain. We conclude that multidimensional aspects in religious measures may account for conflicting prior findings.

Pathological Gambling, Gambling Disorder, and Problem Gambling Among the Chinese Ethnic Population Living in Western Countries: Is Culture a Sufficient Explanation for the Reported Excess Rates?

A significant gap remains in the understanding of the psychosocial and cultural factors and processes in the development and maintenance of pathological gambling, gambling disorder, and problem gambling among the Chinese ethnic population living in the Western countries. This narrative reviews papers on gambling and pathological gambling among the Chinese ethnic group in Western countries to provide a deeper understanding of the cultural and psychosocial factors and processes that lead to the development and maintenance of pathological gambling, gambling disorder, and problem gambling. The factors leading to development of problem gambling, which also carry distinctive cultural differences, include acculturation process among Chinese migrants to western countries, their social learning patterns in gambling, the patterns and motivation seen in Chinese gamblers, their gambling-related cognitive bias and distortions as well as barriers to their help-seeking behaviours. The collectivistic oriental culture may explain for intrafamilial development of gambling behaviour and this strong male authority in the traditional Chinese family set-up also reinforces this influence. The Chinese culture is associated with increased risk-taking behaviour. Superstitious thinking is more prevalent in the Chinese culture and this can be manifested in individuals' perceptions of fate and luck. Future research projects studying pathological gambling and ethnic minorities in the UK should seek greater understanding and improved management of this condition in a small but highly relevant population.

"Should've known better": Counterfactual processing in disordered gambling

Counterfactual thinking is a component of human decision-making that entails "if only" thinking about unselected choices and outcomes. It is associated with strong emotional responses of regret (when the obtained outcome is inferior to the counterfactual) and relief (vice versa). Counterfactual thinking may play a role in various cognitive phenomena in disordered gambling, such as the effects of near-misses. This study compared individuals with gambling disorder (n = 46) and healthy controls (n = 25) on a behavioural economic choice task that entailed choosing between two gambles, designed to measure counterfactual thinking. Participants provided affect ratings following both the obtained and the non-obtained outcomes. Choices were analyzed using a computational model that derived parameters reflecting sensitivity to expected value, risk variance, and anticipated regret. In the computational choice model, the group with gambling disorder showed increased sensitivity to anticipated regret, reduced sensitivity to expected value, and increased preference for high risk-variance gambles. On the affect ratings, the group with gambling disorder displayed blunted emotional sensitivity to obtained and counterfactual outcomes. Effect sizes of the group differences were modest. Participants with gambling disorder show wide-ranging alterations in decision-making processes and emotional reactivity to choice outcomes. Altered sensitivity to anticipatory regret in gambling disorder may contribute to the development of gambling-related cognitive distortions, and the influences of gambling marketing.
