The Iowa Gambling Task (IGT) is one of the most common behavioral decision-making tasks used in clinical and research settings. Less-than-expected performance among healthy adults generates concerns about the validity of this task, and it is possible the particular scoring approach utilized could impact interpretation. We examined how performance patterns changed across several scoring approaches, utilizing a large, college student sample, both with ( n = 406) and without ( n = 1,547) a self-reported history of psychiatric or other diagnosis. Higher net scores were seen when participants selected decks with a low loss frequency than decks with high long-term outcomes; however, participants overall underperformed the IGT normative data sample. Receiver operating characteristic curves examining multiple scoring approaches revealed no threshold of impaired performance that both maximized sensitivity and minimized false positive rate on the IGT. Scoring approach matters in the determination of impaired decision making via the IGT in adults.

AbstractAlthough frontal patients show impaired decision-making on the Iowa Gambling Task (IGT), there has been no follow-up study to date to determine whether there is recovery of function over time. We examined neurological participants’ performance on repeated administrations of the IGT over the course of 6 years. We found that, while non-neurological participants showed considerable improvement due to practice effects on the IGT, patients with ventromedial prefrontal cortex (VMPFC) damage persisted in showing impaired performance on each retest. These results validate the clinical observations that VMPFC dysfunction does not appear to be subject to autonomous recovery over time in real-life. (JINS, 2012, 18, 1–4)
