Iowa gambling task

From Psy3242

The Iowa Gambling Task was created by A. Bechara, H. Damasio, D. Tranel, and A. R. Damasio (1997) of the University of Iowa. It was designed to examine emotion and cognition interaction in decision making.

The Iowa Gambling Task requires the participant to choose cards from four different decks. Each card has a different amount of money on it and can either result in a gain of profit or a loss. Two of the decks, the green and red, have low monetary rewards but lower losses. These are called the advantageous decks. The other two decks, yellow and blue, have high rewards but even higher losses. The IGT is fixed so that if a person picks cards from the advantageous decks, profit will be made, and if the person picks from the disadvantageous decks, the results are monetary deficits. Most participants begin the task by picking cards from the disadvantageous deck, with the high rewards and even higher losses. After a few trials, the participant should see the pattern of loss and begin choosing from the the green and read advantageous decks.

Studies done on the Iowa Gambling Task show differences between age and sex. A study done by Wood, Busemeyer, Coling, Cox, and Davis (2005) indicated that both older and younger adults perfom well on the IGT, but have different means of doing so. Older adults (65-88 yrs.) depend on accrate representations of wins and losses depicted through the IGT. Young adults (18-34 yrs.) rely on the learning from the task and memory.
