New Investigator Grant: “A Novel Approach for Investigating the Neurobiological Basis of Gambling Using a Rodent Analogue of the Iowa Gambling Task”

Principal Investigator: Catharine A. Winstanley, Ph.D., University of British Columbia
Awarded $57,500 in 2006

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.

“Neuropsychological Correlates of Pathological Gambling”

Principal Investigator: Donald W. Black, MD, Professor of Psychiatry, Carver College of Medicine, University of Iowa
Awarded $172,500 in 2006

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.

New Investigator Grant: “Gambling Patterns and Problems: A Longitudinal Study of Change in Gambling Patterns in a College Student Sample”

Principal Investigator: Anna E. Goudriaan, Ph.D., University of Amsterdam
Awarded $57,436 in 2006

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.

“Dopaminergic Neurotransmission and Cognitive Bias in Pathological Gambling”

Principal Investigator: Jakob Linnet, Ph.D., Aarhus University Hospital, Denmark
Awarded $149,185 in 2006

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.
