Abstract
This study examined the relations between impulsivity and decision-making as assessed by the Iowa Gambling Task (IGT). A total of 73 nonclinical adolescents were administered self-report measures for trait impulsivity and the Wisconsin Card Sorting Test (WCST) to assess cognitive impulsivity. We found significant correlations between trait impulsivity and WCST performance among adolescents exhibiting poor performance on the IGT, and no such correlations for those adolescents performing well on the IGT. We recommend that researchers should assess performance on the IGT at the individual level in terms of learning.
