Aim: Address the dearth of knowledge about the professional workforce charged with preventing and treating problem gambling through a survey that will help form a strategy for the design and development of an evidence-based curriculum for delivery to gambling treatment professionals.

Aim: Develop and test a novel model of gambling behavior in rats based on the Iowa Gambling Task (IGT) to determine if the rat IGT (RIGT) is a valid model of gambling behavior and whether damage to the orbitofrontal cortex (OFC) and basolateral amygdala (BLA) increases risky decision-making in keeping with data from human studies.

Aim: Test the hypothesis that persons with a gambling disorder will perform more poorly on measures of executive function (e.g., decision-making), attention and impulsivity, but that general intelligence and memory will not differ.

Aim: Analyze gambling patterns, changes over time in gambling patterns, at-risk gambling and gambling problems in sample of 2,470 college students, thus filling the need for longitudinal studies on sub-clinical gambling problems.

Aim: Test the hypothesis that pathological gamblers have a lower dopamine concentration and a higher dopamine release during gambling compared with healthy controls; that other factors, such as personality traits such as sensation seeking, influence the dopamine release during gambling; and, that dopamine binding potential and occupancy are associated (directly or indirectly) with cognitive bias of gambling performance.
