Reexamining the validity and reliability of the clinical version of the Iowa gambling task…
Over past decade, the Iowa gambling task (IGT) has been utilized to test various decision deficits induced by neurological damage or psychiatric disorders. The IGT has recently been standardized for identifying 13 different neuropsychological disorders.
Standard (default) Based on the standard Iowa gambling task described by Damasio et al. (1991). Fifty trials are completed using four decks. Two decks have small rewards and penalties, but lead to net gain over time. Two decks have large rewards and large

The Iowa Gambling Task and Risky Decision Making
In this case, the task is something called the Iowa Gambling Task (IGT). The IGT is a simple game where you win or lose money, and different people play the game with different strategies. I’m going to talk briefly about how the game works, what it tells us about how people make decisions and evaluate risk, and how the strategy you use might say something about how you make decisions.

The present study focuses on the role of frequency bias and expected value on the learning processes driving performance on the Iowa Gambling Task (IGT) in individuals between 5 and 89 years of age. As in previous studies, children performed poorly on the IGT, were increasingly influenced by frequency of losses during learning, and constantly changed their decisions. Decision-making strategies

O Iowa Gambling Task: uma revisão crítica
The Iowa Gambling Task (IGT) is a widely used task in the assessment of the decision-making ability. In this article, we conduct a literature review by comparing IGT versions, different performance assessment measures, and changes to procedures including feedback, spatial randomization of decks, number of trials, number of cards per deck, instructions, payment, and rewards and punishments.

· The Iowa Gambling Task (IGT) is one of the most common paradigms used to assess decision-making and executive functioning in neurological and psychiatric disorders. 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.

The Iowa Gambling Task (IGT) has become a remarkable experimental paradigm of dynamic emotion decision making. In recent years, research has emphasized the “prominent deck B (PDB) phenomenon” among normal (control group) participants, in which they favor “bad” deck B with its high-frequency gain structure—a finding that is incongruent with the original IGT hypothesis concerning
