Iowa Gambling Task Purchase

• The original IGT was conducted to identify individuals with damage to the ventromedial prefrontal cortex (Bechara et al. 1994) and has since been used as a base for further research into the causes and implications the damage has; the successful replication therefore supports the use of this task within the understanding of the damage.

Iowa Gambling Task (IGT) The Iowa Gambling experiment was created to determine the nature of impairment in decision making (Bechara et al., 1994). The neuroimaging techniques implemented within the framework of the IGT experiment allow for real-time monitoring of neural processes lying at the core of the decision-making process. Humans: the Iowa Gambling Task 1.1 Developing a simulation of real-life decision-making When it was designed by Bechara and colleagues in the early 90s (Bechara et al., 1994), the IGT was meant to be a tool to specifically test impairements of decision-making in a controlled labo-ratory setting.

Iowa Gambling Task Bechara 1994 Movie

A decision task designed to simulate real-life decision-making. On each trial the decision maker chooses a card from one of four decks, each choice resulting in a fixed gain of $100 for any card from two of the decks or $50 for any card from the other two, although the decision maker is not told this. For some cards, the decision maker also suffers a loss. Losses total $1,250 for every ten cards in two of the decks and $250 for every ten cards in the other two. These gains and losses are arranged so that two of the decks yield substantial expected losses and the other two substantial expected gains over every run of 10 cards, but there are sharp differences between short-term and long-term payoffs, small losses occurring relatively frequently in some decks and larger but less frequent losses occurring in others. The task was introduced by the Canadian neuroscientist Antoine Bechara (born 1961) and published with three colleagues in the journal Cognition in 1994, where it was shown that people with damage to the prefrontal cortex, in contrast to neurologically undamaged participants in their control group, performed badly, failing to consider the future consequences of their actions and being guided only by immediate prospects.
