However, the poor performance by clinical populations can arise from at least three different sources in this task. While bottom-up decision making-related brain activity may be enhanced, these findings suggest that reward evaluation may be compromised in heavy alcohol users. This task has been used in numerous neuropsychological studies showing impaired decision making after orbitofrontal cortex damage [86,87] see also Chapter Two disadvantageous decks provide immediate large rewards but also substantial money losses.

The Iowa gambling task is a decision-making task that has been used in an fMRI study of binge drinkers and showed that heavy alcohol users make more disadvantageous decisions on the task than nonusers Xiao et al.

Progress in Brain Research, The task involves four virtual card decks represented on a computer screen. The object of the game is to win money, and when a card is drawn the result may be to add or subtract. The four decks are not created equal. Adolescent heavy alcohol use may be associated with immature decision-making abilities that lead to maladaptive risk taking. Significantly, elevated insular and amygdalar response was present in binge drinkers during the task compared to controls, and insular response was positively related to drinking problems and urgency scores, a measure of impulsive behavior driven by negative emotions.

These findings, similar to altered insular white matter volume in heavy alcohol users, may indicate that bottom-up affect-driven decision making may be related to risky behaviors, such as binge drinking.

A comparison of current binge drinkers and controls that identified brain areas that best differentiated the two groups via a machine learning analysis found that ventromedial PFC and inferior frontal gyrus activity were reduced during reward anticipation and consumption in binge drinkers compared with controls Whelan et al.

The Iowa gambling task IGT is a psychological task thought to simulate real-life decision making. Later, it has been referred to as the Iowa gambling task and, less frequently, as Bechara's Gambling Task. A recent review listed more than papers that made use of this paradigm. Participants are presented with 4 virtual decks of cards on a computer screen.

They are told that each deck holds cards that will either reward or penalize them, using game money. The goal of the game is to win as much money as possible.

The decks differ from each other in the balance of reward versus penalty cards. Thus, some decks are "bad decks", and other decks are "good decks", because some decks will tend to reward the player more often than other decks. Most healthy participants sample cards from each deck, and after about 40 or 50 selections are fairly good at sticking to the good decks. Patients with orbitofrontal cortex OFC dysfunction, however, continue to persevere with the bad decks, sometimes even though they know that they are losing money overall.

Concurrent measurement of galvanic skin response shows that healthy participants show a "stress" reaction to hovering over the bad decks after only 10 trials, long before conscious sensation that the decks are bad.

In another test, patients with ventromedial prefrontal cortex VM dysfunction were shown to choose outcomes that yield high immediate gains in spite of higher losses in the future. The Iowa gambling task is currently being used by a number of research groups using fMRI to investigate which brain regions are activated by the task in healthy volunteers [7] as well as clinical groups with conditions such as schizophrenia and obsessive compulsive disorder.
