Abstract

Neurocognitive Mechanisms of Impaired Decision Making in Pathological Gambling

Highlights

Power et al (2012) used functional magnetic resonance imaging to investigate the neural systems underpinning the decision making performance of pathological gamblers (PG) and nongamblers on the Iowa Gambling Task (IGT: Bechara et al, 1994)
A commentary on Neural correlates of pathological gamblers preference for immediate rewards during the Iowa Gambling Task: an functional magnetic resonance imaging (fMRI) study by Power, Y., Goodyear, B., and Crockford, D. (2012)
Two of the decks result in frequent immediate high gain, but produce high-magnitude losses of differing frequencies depending on the deck, leading to a cumulative long-term loss (“risky decks”)
