Facing temptation: The neural correlates of gambling availability during sports picture exposure

Nowadays, sports betting has become increasingly available and easy to engage in. Here we examined the neural responses to stimuli that represent sporting events available for betting as compared to sporting events without a gambling opportunity. We used a cue exposure task in which football (soccer) fans (N = 42) viewed cues depicting scheduled football games that would occur shortly after the scanning session. In the “betting” condition, participants were instructed to choose, at the end of each block, the game (and the team) they wanted to bet on. In the “watching” condition, participants chose the game they would prefer to watch. After the scanning session, participants completed posttask rating questionnaires assessing, for each cue, their level of confidence about the team they believed would win and how much they would enjoy watching the game. We found that stimuli representing sport events available for betting elicited higher fronto-striatal activation, as well as higher insular cortex activity and functional connectivity, than sport events without a gambling opportunity. Moreover, games rated with more confidence towards the winning team resulted in greater brain activations within regions involved in affective decision-making (ventromedial prefrontal cortex), cognitive inhibitory control (medial and superior frontal gyri) and reward processing (ventral and dorsal striatum). Altogether, these novel findings offer a sensible simulation of how the high availability of sports betting in today’s environment impacts on the reward and cognitive control systems. Future studies are needed to extend the present findings to a sample of football fans that includes a samilar proportion of female and male participants.     

Prevalence and correlates of gambling among 16 to 19-year-old adolescents in Norway

There is evidence that young people are at high risk of developing gambling disorders. The prevalence and correlates of gambling among youth therefore merit closer study. During spring 2004, a sample of 1,351 boys and girls (aged 16–19 years) from 151 high-school classes (clusters) participated in an internet survey about gambling. The response rate was 69.8%. The instruments used in the survey were the Hospital Anxiety and Depression Scale, the Alcohol Use Disorders Identification Test and the Massachusetts Adolescent Gambling Screen, in addition to questions about demography. Controlling for the design effect, the estimated prevalence rate was 2.5% for pathological gambling and 1.9% for problem gambling. In all, 7.3% of the boys and 0.6% of the girls fulfilled the criteria for pathological or problem gambling. The results of item analysis of the DSM-IV subscale of MAGS provide support for differential item functioning between boys and girls. A multiple logistic regression analysis revealed that gender (male: OR = 9.09), depression (OR = 9.23), alcohol abuse (OR = 3.62), and dissociation (OR = 1.96) were related to problem and pathological gambling. These results support the view that gambling disorders are best understood as part of an addictive behavior spectrum ( Jacobs, 2000 ).     

Feedback related brain activity in a gambling task: A temporal analysis of EEG correlates

Lucchiari, C. & Pravettoni, G. (2010). Feedback related brain activity in a gambling task: A temporal analysis of EEG correlates. Scandinavian Journal of Psychology 51, 449–454. The pattern of neural correlates of feedback processing has been the subject of a number of studies, using both neuroimaging and electrophysiological recordings. A complex functional network was found to be activated after a choice in order to process a feedback and sustain an adaptive behavior. However, many aspects of this network are still unclear and further research is needed to better understand this process. We conducted an EEG study using a simple gambling task. Twenty three subjects participated to the study. We analyzed both EEG power spectrum and ERP components evoked by presentation of a feedback signal (money gain or loss) during a simple gambling task. Our data confirmed that a negative ERP component is present about 270 ms after feedback, particularly relevant following a choice with negative outcome. Furthermore, the theta and delta oscillatory activity seem to be correlated to a dynamic decision‐making process within specific cortical networks. In particular, theta activity showed a valence dependent development between 150 and 350 ms post‐feedback onset. Differently from previous studies (Cohen, Elger & Ranganath, 2007; Marco‐Pallares, Cucurell, Cunillera et al., 2008), we did not find any valence effect in beta range. However, our data are consistent with Christie and Tata (2009) , probably due to the nature of the gambling task used in both studies. In conclusion, our data, in line with some prior findings showed that the feedback related response is correlated to a complex pattern of cortical activation probably mediated by theta and delta activity.     

Health-related behaviours and their correlates in a general population sample of 45-year old women

Abstract

Preventive strategies for menopausal women to reduce the risks for osteoporosis and cardiovascular disease has been the focus of considerable attention, but understanding of mid-aged women's behavioural risk factors for these diseases is meagre. The current study describes a range of health-related behaviours and their psychosocial correlates, in a sample of 45-year old women, recruited from five general practices and assessed by postal survey (N=106, response rate 60%). Results suggest that health promotion for this group might best focus upon increases in regular exercise, calcium intake and breast awareness, and decreases in cigarette and caffeine consumption. The behaviours assessed were generally not inter-related. However, several associations were identified between behaviours and health and psychosocial variables. The main ones were the association between menopausal status and smoking, and the relationship between body weight, self-esteem and physical exercise. It is argued that the menopause transition can be an opportunity for preventive work.     

Brown on Mackie: Echoes of the Lottery Paradox

In “The possibility of morality,” Phil Brown considers whether moral error theory is best understood as a necessary or contingent thesis. Among other things, Brown contends that the argument from relativity, offered by John Mackie—error theory’s progenitor—supports a stronger modal reading of error theory. His argument is as follows: Mackie’s is an abductive argument that error theory is the best explanation for divergence in moral practices. Since error theory will likewise be the best explanation for similar divergences in possible worlds similar to our own, we may conclude that error theory is true at all such worlds, just as it is in the actual world. I contend that Brown’s argument must fail, as abductive arguments cannot support the modal conclusions he suggests. I then consider why this is the case, concluding that Brown has stumbled upon new and interesting evidence that agglomerating one’s beliefs can be epistemically problematic—an issue associated most famously with Henry Kyburg’s lottery paradox.     

Complexity effects on the children's gambling task

The children's gambling task (CGT [Kerr, A., & Zelazo, P. D. (2004). Development of “Hot” executive function: The children's gambling task. Brain and Cognition, 55, 148–157]) involves integrating information about losses and gains to maximize winnings when selecting cards from two decks. Both cognitive complexity and control (CCC) theory and relational complexity (RC) theory attribute younger children's difficulty to task complexity. In CCC theory, identification of the advantageous deck requires formulation of a higher-order rule so that gains and losses can be considered in contradistinction. According to RC theory, it entails processing the ternary relation linking three variables (deck, magnitude of gain, magnitude of loss). We designed two less complex binary-relational versions in which either loss or gain varied across decks, with the other held constant. The three closely matched versions were administered to 3–5-year-olds. Consistent with complexity explanations, children in all age groups selected cards from the advantageous deck in the binary-relational versions, but only 5-year-olds did so on the ternary-relational CGT.     

Criminal Attempts and the Penal Lottery

In most penal systems, success is punished more than failure. For example, murder is punished more severely than attempted murder. But success or failure is often determined by luck. It thus appears that punishment is allotted on the basis of arbitrary factors. The problem of criminal attempts is the question of how to best resolve this apparent tension. One particularly sophisticated attempt at resolution, first developed by David Lewis, holds that such differential punishment is not unjust when understood as a natural penal lottery. What is most interesting about this view is that it does not appear to involve a commitment to resultant moral luck. I argue that the natural penal lottery fails to deliver justice. Upon analysis, it carries the same implication that it sought to avoid—namely, a commitment to resultant moral luck. I then argue that there can be, in principle, no penal lottery that delivers justice, natural or otherwise.     

The impact of comorbidity on the management of pathological gambling

A 30-year-old woman with severe pathological gambling and cyclothymia presented to our program with no previous history of pharmacologic or psychotherapeutic treatment. Pathological gambling is an impulse -control disorder not otherwise specified (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) in which comorbidity is common, particularly with substance abuse, obsessive-compulsive disorder and mood disorders. As described in this case, pathological gamblers with bipolar comorbidity may be effectively treated with mood stabilizers such as lithium. After receiving 10 weeks of lithium treatment, the patient showed improvement in both gambling behavior and affective instability. The identification of specific subtypes among patients with pathological gambling may be relevant to the choice of pharmacologic treatment.

No-loss gambling shows the speed of the unconscious

This paper investigates the time it takes unconscious vs. conscious knowledge to form by using an improved "no-loss gambling" method to measure awareness of knowing. Subjects could either bet on a transparently random process or on their grammaticality judgment in an artificial grammar learning task. A conflict in the literature is resolved concerning whether unconscious rather than conscious knowledge is especially fast or slow to form. When guessing (betting on a random process), accuracy was above chance and RTs were longer than when feeling confident (betting on the grammaticality decision). In a second experiment, short response deadlines only interfered with the quality of confident decisions (betting on grammaticality). When people are unaware of their knowledge, externally enforced decisions can be made rapidly with little decline in quality; but if given ample time, they await a metacognitive process to complete. The dissociation validates no-loss gambling as a measure of conscious awareness.     

Health at work in the British National Health Service: A counselling response

This article outlines the historical context that led to an employee counselling service in an NHS Trust in the North East of England being established. It describes the process of implementation and development of the Service. It evaluates the Service using data collated from those using the Service and also client evaluation reports. It critically analyses the data collated from use of the Service after two years. The paper concludes that one of the key issues of the 'Health at Work in the NHS' Initiative--that of staff support--is continuing to be appropriately addressed through the presence of the Service. Although the future of the service is uncertain due to mergers within the Health Trust, indicators still show that staff value and benefit from the Service.     

"It Could Be Us!": Cognitive and Social Psychological Factors in UK National Lottery Play

This study examines the cognitive and social psychological factors underlying UK National Lottery play. A total of 384 respondents were asked about their own lottery playing behaviours, their knowledge of lottery odds and their beliefs about the role of skill, chance, luck and optimism in lottery play. Using hypothetical scenarios, respondents were also asked to rate the likelihood of winning the lottery jackpot (matching all six numbers) with number combinations reflecting different levels of apparent randomness, previous matches, near misses and prize size manipulations. Frequency of lottery play was found to be positively correlated with age, income, Instants scratchcard play, gambling on horse/greyhound racing, the football pools, and bingo as well as with beliefs about skill, luck and optimism. Frequency of lottery play was negatively correlated with general education and estimate of relative win likelihoods based on the perceived randomness of number combinations. Planned contrasts revealed that compared to individual (non‐syndicate) players, syndicate lottery players played more regularly and gambled more on the football pools. Results are discussed in the light of current cognitive theories surrounding the misperception of probability and their relation to lottery play and in the need for future models to recognise the social factors inherent in syndicate‐based lottery participation.     

Affective guidance in the Iowa gambling task

It has been suggested that affective states can guide higher level cognitive processes and that such affective guidance may be particularly important when real-life decisions are made under uncertainty. We ask whether affect guides decisions in a laboratory task that models real-life decisions under uncertainty. In the Iowa gambling task (IGT), participants search for monetary payoffs in an uncertain environment. Recent evidence against an affective guidance interpretation of the IGT indicates a need to set a standard for what counts as evidence of affective guidance. We present a novel analysis of IGT, and our results show that participants’ galvanic skin response (GSR) reflects an affective process that precedes and guides cognition. Specifically, prior to participants’ knowledge of the optimal strategy, their GSRs are significantly higher when they are about to select from a bad deck, relative to a good deck, and this difference in GSR is correlated with a behavioral preference for the good deck.     

A simple model for the utility of gambling

A model of the utility of gambling is presented in a modified von Neumann-Morgenstern format. Axioms imply a utility function that preserves preferences between sure things and between gambles. The addition of a utility of gambling term to the expected utility of a gamble preserves preference comparisons between gambles and sure things. Aspects of the utility of gambling are noted, and comparisons are made to standard concepts of risk attitudes.The author is indebted to Joseph Sani for valuable discussions on the topic of this paper.
