O Iowa Gambling Task. Uma revisão crítica
TLDR
This paper conducted a literature review by comparing IGT versions, different performance assessment measures, and changes to procedures including feedback, spatial randomization of decks, number of trials, the number of cards per deck, instructions, payment, and rewards and punishments.Abstract:
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. On basis of this analysis, we conclude that different versions of the task, changes in application procedures and different measures used to assess the task have an impact on performance, thereby affecting comparison among studies and generalization of results. Finally, we offer suggestions to define adequate procedures.read more

TL;DR: Examination of older adults' decision-making on the Iowa Gambling Task highlights that older adults are able to move from the initial uncertainty, when the possible outcomes are unknown, to decisions based on risk,When the outcomes are learned and may be used to guide future adaptive decision- making.

Prospect theory: an analysis of decision under risk
Daniel Kahneman,Amos Tversky +1 more
TL;DR: In this paper, the authors present a critique of expected utility theory as a descriptive model of decision making under risk, and develop an alternative model, called prospect theory, in which value is assigned to gains and losses rather than to final assets and in which probabilities are replaced by decision weights.

Insensitivity to future consequences following damage to human prefrontal cortex
TL;DR: Using a novel task which simulates real-life decision-making in the way it factors uncertainty of premises and outcomes, as well as reward and punishment, it is found that prefrontal patients are oblivious to the future consequences of their actions, and seem to be guided by immediate prospects only.

Deciding Advantageously Before Knowing the Advantageous Strategy
TL;DR: The results suggest that, in normal individuals, nonconscious biases guide behavior before conscious knowledge does, and without the help of such biases, overt knowledge may be insufficient to ensure advantageous behavior.
