Abstract
OBJECTIVE: To examine differences between two versions of the Iowa Gambling Task (IGT). METHOD: A total of 282 undergraduate students completed one of two versions of the IGT: the original version from 1994 (n = 132), or the 2007 version available through Psychological Assessment Resources (PAR) (n = 150). RESULTS: PAR (2007 version) IGT participants decided more advantageously (i.e., selected more from the small immediate reward but long-term positive/gain decks than the large immediate reward but long-term negative/loss decks) than original IGT participants during Trials 21-60. This difference was likely due to fewer Deck B selections by the PAR IGT participants during the early (Trials 1-40) and later (Trials 41-100) trials. CONCLUSIONS: The PAR IGT may result in a greater ability to make future-oriented, advantageous decisions more quickly than on the original IGT. Implications for future assessment of decision-making impairments in clinical and research settings are discussed.
