Associations Between Delay Discounting and Risk‐Related Behaviors,Traits, Attitudes,and Outcomes

Delay discounting—preference for immediate, smaller rewards over distal, larger rewards—has been argued to be part of the “generality of deviance”, which describes the co‐occurrence of various forms of impulsive and risky behaviors among individuals. Some studies have linked laboratory‐measured delay discounting to behaviors, traits, attitudes, and outcomes associated with risk, but these associations have been inconsistent. Furthermore, many of these studies have been conducted with exclusively undergraduate samples, or in samples offering low statistical power. In a large community sample (n = 328) diverse in age and socioeconomic status, we examined associations between two measures of behavioral delay discounting (single‐shot and canonical k‐parameter estimation) and behavioral risk‐taking, personality traits associated with risk, domain‐specific risk attitudes, gambling and problem gambling, antisocial behavior, and criminal outcomes. In addition, we explored whether a novel response time latency measure of delay discounting explained variance in these risk‐related outcomes. Results indicated that behavioral delay discounting was consistently associated with all variables related to impulse control: high trait impulsivity, low trait self‐control, risk‐averse attitudes toward financial investment, risk‐prone attitudes toward gambling and health/safety risks, gambling and problem gambling, antisocial conduct, and criminal outcomes. Latency‐measured delay discounting was inconsistently associated with behavioral delay discounting and risk‐related measures. Together, results suggest that delay discounting is associated with poor impulse control consistent with a generality of deviance account. Copyright © 2016 John Wiley & Sons, Ltd.     

澳门人少涉赌是规避风险还是规避后悔？

是风险规避还是后悔规避左右人们的冒险行为？基于风险行为跨领域特殊性,本研究假设：决策者是规避风险还是规避后悔具有领域特异性。本研究选取有涉赌经验的澳门居民为样本,以其参与13种博彩的次数为指标考察其真实风险行为。结果验证了上述假设,风险规避说或后悔规避说都不能单独解释个体的风险倾向,个体是风险规避、后悔规避,或二者皆有,取决于其所处的具体风险情境类别。该发现有助于加深对风险行为特征的认识,亦可为预防及应对问题赌博提供启发和指导。     

Cognitive-behavioural treatment of pathological gambling in individuals with chronic schizophrenia: a pilot study

The current study aimed to test the clinical effectiveness of a cognitive-behavioural program (CBT) specifically adapted for pathological gamblers with chronic schizophrenia, carried out in a naturalistic setting of community Mental Health Centres. Forty-four pathological gamblers with chronic schizophrenia were assigned either to a standard drug therapy for schizophrenia (control group) or to cognitive-behavioural therapy for pathological gambling plus a standard drug therapy for schizophrenia (experimental group). Psychological treatment comprised a 20-session program including psychoeducation, stimulus control, gradual exposure and relapse prevention. Therapeutic success was defined as abstinence or the occurrence of only 1 or 2 episodes of gambling during the follow-up period. While the patients treated in the experimental group showed a rate of success of 73.9%, only 19% of the participants belonging to the control group gave up gambling at the 3-month follow-up. The CBT group also did better than the control group in the number of gambling episodes and in the amount of money spent on gambling. However, the improvement of the experimental group was weaker at the 6- and 12-month follow-up. These findings support the beneficial effects of CBT as adjunctive therapy for patients with dual diagnoses (schizophrenia and pathological gambling).     

Development of hot and cool executive function during the transition to adolescence

This study examined the development of executive function (EF) in a typically developing sample from middle childhood to adolescence using a range of tasks varying in affective significance. A total of 102 participants between 8 and 15 years of age completed the Iowa Gambling Task, the Color Word Stroop, a Delay Discounting task, and a Digit Span task. Age-related improvements were found on all tasks, but improvements on relatively cool tasks (Color Word Stroop and Backward Digit Span) occurred earlier in this age range, whereas improvements on relatively hot tasks (Iowa Gambling Task and Delay Discounting) were more gradual and occurred later. Exploratory factor analysis indicated that performance on all tasks could be accounted for by a single-factor model. Together, these findings indicate that although similar abilities may underlie both hot and cool EF, hot EF develops relatively slowly, which may have implications for the risky behavior often observed during adolescence. Future work should include additional measures to characterize more intensively the development of both hot and cool EF during the transition to adolescence.     

Derived transformation of children's pregambling game playing

Contemporary behavior-analytic perspectives on gambling emphasize the impact of verbal relations, or derived relational responding and the transformation of stimulus functions, on the initiation and maintenance of gambling. Approached in this way, it is possible to undertake experimental analysis of the role of verbal/mediational variables in gambling behavior. The present study therefore sought to demonstrate the ways new stimuli could come to have functions relevant to gambling without those functions being trained directly. Following a successful derived-equivalence-relations test, a simulated board game established high- and low-roll functions for two concurrently presented dice labelled with members of the derived relations. During the test for derived transformation, children were reexposed to the board game with dice labelled with indirectly related stimuli. All participants except 1 who passed the equivalence relations test selected the die that was indirectly related to the trained high-roll die more often than the die that was indirectly related to low-roll die, despite the absence of differential outcomes. All participants except 3 also gave the derived high-roll die higher liking ratings than the derived low-roll die. The implications of the findings for behavior-analytic research on gambling and the development of verbally-based interventions for disordered gambling are discussed.     

Aggressive behaviour in adult slot machine gamblers: an interpretative phenomenological analysis

A growing number of studies have reported a link between gambling and aggressive behaviour. The aim of this study was to contextualize objective findings of a previous observational study regarding slot machine gambling and aggressive behaviour (Parke & Griffiths, Psychological Reports, 95, 109–114, 2004). Interpretative Phenomenological Analysis was applied using the Idiographic Case Study method. The data revealed three superordinate themes regarding slot machine gambling‐induced aggression (i.e. Competitive Advantage Reduction, Self‐esteem Reduction, and Cognitive Regret). Within these superordinate themes, subordinate themes emerged identifying how environmental factors and structural characteristics of slot machine gambling, along with the consequences of losing, produced aggressive behaviour. It is concluded that gambling‐induced aggression is a manifestation of the underlying conflict of engaging in dysfunctional behaviour while consciously acknowledging its detrimental effects.

A new spin on losses looming larger than gains: asymmetric implicit associations from slot machine experience

Kahneman and Tversky's prospect theory states, among other things, that losses loom larger than gains. As much research as this simple idea has generated, key questions remain. How fundamental is the losses‐looming‐larger effect: will it emerge under more minimal circumstances than previously tested and will it manifest in implicit associations? And how does the actual experience of predominant losses or gains affect the losses‐looming‐larger effect? In two experiments employing non‐traditional methods, participants experienced slot machine spins in which symbols were paired with gain, loss, and neutral outcomes. After experiencing these pairings, participants took Implicit Association Tests (IATs). In Experiment 1, implicit associations formed by the minimal experience of the slot machine were lopsided: negative associations with the loss symbol were stronger than positive associations with the gain symbol. In addition, it was found that the extent to which losses loomed larger depended on the context of the slot machine experience, with losses looming implicitly larger than gains most when they were fewer in number (participants experienced a net‐gain) and least when they were the predominant outcome (participants experienced a net‐loss). Finally, in Experiment 2, a potential artifact was ruled out and a replication obtained by showing that slot machine losses implicitly loom larger whether conceptualized from the perspective of a casino player or a casino owner.

Gambling behavior and gambling problems in Norway 2007

In Norway, legalized gambling is pervasive, easily accessible and socially accepted, particularly the participation in national lotteries. We conducted a stratified probability sample study during January–March 2007 (age group 16–74 years, N  = 3,482, response rate 36.1%) to assess gambling behavior and prevalence of problematic gambling by the NORC Diagnostic Screen (NODS). Overall, 67.9% of the study population had been engaged in past-year gambling and 0.7% were past-year problematic gamblers (NODS score 3+). Male gender, low educational level, single marital status, and being born in a non-Western country were variables positively associated with problematic gambling. Past-year problematic gamblers indicated the slot machine (34.6%) and Internet gambling (26.9%) as the most important games, while most non-problematic gamblers pointed out the lotteries (62.3%) as the most important game. The prevalence of self-reported sleeping disorders, depression and other psychological impairments was significantly higher among problematic gamblers. Gambling problems affect people's lives in multiple ways.     

Personality factors as predictors of pathological gambling

The aim of this study was to investigate the relationship between different personality variables and pathological gambling (PG). The NEO-FFI and measures of impulsivity and sensation-seeking were administered to a sample of pathological gamblers (n = 90) and to a contrast group of non-pathological gamblers (n = 66) matched on sex and age. Gender, age, education level and the personality variables were entered into crude and adjusted logistic regression analyses with PG-status as the dependent variable. The results showed that educational level and all personality variables were significant predictors of PG in the crude analyses, however only four of the 12 significant predictor variables (Neuroticism, Openness, Impulsivity, and need for Stimulus Intensity) remained significant in the adjusted analysis. All predictor variables accounted for 71% of the variance in PG-status. Clinical implications of the findings are discussed.     

Neurobehavioral evidence for the "Near-Miss" effect in pathological gamblers

The purpose of this translational study was twofold: (1) to contrast behavioral and brain activity between pathological and nonpathological gamblers, and (2) to examine differences as a function of the outcome of the spin of a slot machine, focusing predominately on the "Near-Miss"--when two reels stop on the same symbol, and that symbol is just above or below the payoff line on the third reel. Twenty-two participants (11 nonpathological; 11 pathological) completed the study by rating the closeness of various outcomes of slot machine displays (wins, losses, and near-misses) to a win. No behavioral differences were observed between groups of participants, however, differences in brain activity were found in the left midbrain, near the substantia nigra and ventral tegmental area (SN / VTA). Near-miss outcomes uniquely activated brain regions associated with wins for the pathological gamblers and regions associated with losses for the nonpathological gamblers. Thus, near-miss outcomes on slot machines may contain both functional and neurological properties of wins for pathological gamblers. Such a translational approach to the study of gambling behavior may be considered an example that gives life to B. F. Skinner's conceptualization of the physiologist of the future.
