Objective: A critical issue in research related to the Iowa gambling task (IGT) is the use of the alternative factors expected value and gain–loss frequency to distinguish between clinical cases and control groups. The IGT is now considered an appropriate task to predict behavioral disorders in various clinical populations. In the mid-1990s, a task was designed to mimic real life decision-making in the laboratory. The researchers compared the decisions made by 17 healthy controls and 8 patients with lesions in their vmPFCs during the Iowa Gambling Task. The Iowa Gambling Task (IGT) is one of the most extensively used decision-making tasks and is a computer based card game developed to characterize the neurological basis for deficits in decision-making in patients with lesions to the vmPFC and otherwise normal in terms of IQ, measures of impulsivity, working memory, and basic.

Although most SDIs are impaired on the IGT, there is a subgroup of them who perform normally on this task. Very few studies have employed the IGT in functional magnetic resonance imaging (fMRI) investigations, in part, because the task is cognitively complex. Support for the hypothesis comes from observing healthy participants’ ability to make long-term advantageous decisions on a task called the Iowa gambling task (IGT; Bechara et al.

The participant needs to choose one out of four card decks (named A,B,C, and D). (), henceforward referred to as the Iowa gambling task (IGT), participants must select, on each trial, a card from one of four decks ()On every card, participants win some play money. The Iowa Gambling Task was developed to characterize deficits in decision making shown by some clinical patients. Several reinforcement-learning (RL) models were recently proposed to refine the qualitative and quantitative inferences that can be made about these processes based on IGT data. However, it is not clear how basic task properties such as the frequency and magnitude of rewards and losses affect choice behavior in drug users and even in healthy players. g. , prefer options with positive long-term outcome), hence questioning its basic assumptions.
