The globalizability of temporal discounting.

Economic inequality is associated with preferences for smaller, immediate gains over larger, delayed ones. Such temporal discounting may feed into rising global inequality, yet it is unclear whether it is a function of choice preferences or norms, or rather the absence of sufficient resources for immediate needs. It is also not clear whether these reflect true differences in choice patterns between income groups.

The effects of alcohol on sequential decision-making biases during gambling.

Rationale: Gambling and alcohol use are recreational behaviours that share substantial commonalities at a phenomenological, clinical and neurobiological level. Past studies have shown that alcohol can have a disinhibiting effect on gambling behaviour, in terms of bet size and persistence.

Objectives: This study was conducted in order to characterise how alcohol affects biases in judgment and decision-making that occur during gambling, with a focus on sequential decision-making including the gambler's fallacy.

Role Reversal: The Influence of Slot Machine Gambling on Subsequent Alcohol Consumption.

Experimental studies examining the relationship between alcohol use and gambling have focused predominantly on alcohol's influence on gambling behavior. There has been little consideration of the reverse pathway: whether gambling influences subsequent alcohol use. Two experiments examined whether gambling and gambling outcomes (i.

Let me take the wheel: Illusory control and sense of agency.

Illusory control refers to an effect in games of chance where features associated with skilful situations increase expectancies of success. Past work has operationalized illusory control in terms of subjective ratings or behaviour, with limited consideration of the relationship between these definitions, or the broader construct of agency. This study used a novel card-guessing task in 78 participants to investigate the relationship between subjective and behavioural illusory control.

Microstructural white matter changes in the corpus callosum of young people with Bipolar Disorder: a diffusion tensor imaging study.

To date, most studies of white matter changes in Bipolar Disorder (BD) have been conducted in older subjects and with well-established disorders. Studies of young people who are closer to their illness onset may help to identify core neurobiological characteristics and separate these from consequences of repeated illness episodes or prolonged treatment. Diffusion tensor imaging (DTI) was used to examine white matter microstructural changes in 58 young patients with BD (mean age 23 years; range 16-30 years) and 40 controls.

Pathways to alcohol-induced brain impairment in young people: a review.

Classically, disorders associated with 'alcohol-related brain damage' (ARBD) occur as a result of chronic excessive alcohol misuse and confer significant physical and psychological disability to the individual as well as to the community. These phenotypes are often difficult to detect at early stages and therefore early intervention and treatment is limited. It remains unresolved as to whether there are neurobiological markers of the early stages of such brain damage in young 'at-risk' drinkers, who probably experience 'alcohol-induced brain impairment' prior to the onset of ARBD, per se.

Effects of acute alcohol consumption on executive cognitive functioning in naturalistic settings.

Laboratory studies have demonstrated that acute alcohol intoxication can disrupt performance on neuropsychological tests of executive cognitive functioning such as the Wisconsin Card Sorting Test (WCST). However, the generalizability of such findings to typical self-regulated alcohol intake in social settings can be questioned. In the present study, 86 young adults were recruited at Australian bars to perform a computer version of the WCST.
