Objective: A critical issue in research related to the Iowa gambling task (IGT) is the use of the alternative factors expected value and gain–loss frequency to distinguish between clinical cases and control groups. When the IGT has been used to examine cases of Internet addiction (IA), the literature reveals inconsistencies in the results.

Predictors of decision-making on the Iowa Gambling Task: Independent effects of lifetime history of substance use disorders and performance on the Trail Making Test.

Brain Cogn. 2007 Oct 15;

Authors: Barry D, Petry NM

Poor decision-making and executive function deficits are frequently observed in individuals with substance use disorders (SUDs), and executive deficits may contribute to poor decision-making in this population. This study examined the influence of lifetime history of an alcohol, cocaine, heroin, or polysubstance use disorder on decision-making as measured by the Iowa Gambling Task (IGT) after controlling for executive ability, demographic characteristics, and current substance use. Participants (131 with lifetime history of SUD and 37 controls) completed the IGT and two neuropsychological tests: the Trail Making Test and the Controlled Oral Word Association Test. Control participants performed significantly better than those with a lifetime SUD history on the IGT, but performance on the neuropsychological tests was comparable for the two groups. A lifetime SUD diagnosis was associated with performance on the IGT after controlling for covariates, and Trail Making Test performance was associated with IGT performance in both SUD and control participants.

The Iowa gambling task (IGT) is a psychological task thought to simulate real-life decision making.It was introduced by Antoine Bechara, Antonio Damasio, Hanna Damasio and Steven Anderson,^[1] then researchers at the University of Iowa. It has been brought to popular attention by Antonio Damasio (proponent of the somatic marker hypothesis) in his best-selling book Descartes' Error.^[2]

The task was originally presented simply as the Gambling Task, or the 'OGT'. Later, it has been referred to as the Iowa gambling task and, less frequently, as Bechara's Gambling Task.^[3] The Iowa gambling task is widely used in research of cognition and emotion. A recent review listed more than 400 papers that made use of this paradigm.^[4]

Task structure[edit]

Participants are presented with four 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.

Common findings[edit]

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.^[5] By contrast, patients with amygdala lesions never develop this physiological reaction to impending punishment. In another test, patients with ventromedial prefrontal cortex (vmPFC) dysfunction were shown to choose outcomes that yield high immediate gains in spite of higher losses in the future.^[6] Bechara and his colleagues explain these findings in terms of the somatic marker hypothesis.

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.

Critiques[edit]

Although the IGT has achieved prominence, it is not without its critics. Criticisms have been raised over both its design and its interpretation. Published critiques include:

• A paper by Dunn, Dalgliesh and Lawrence^[4]
• Research by Lin, Chiu, Lee and Hsieh,^[8] who argue that a common result (the 'prominent deck B' phenomenon) argues against some of the interpretations that the IGT has been claimed to support.
• Research by Chiu and Lin,^[9] the 'sunken deck C' phenomenon was identified, which confirmed a serious confound embedded in the original design of IGT, this confound makes IGT serial studies misinterpret the effect of gain-loss frequency as final-outcome for somatic marker hypothesis.
• A research group in Taiwan utilized an IGT-modified and relatively symmetrical gamble for gain-loss frequency and long-term outcome, namely the Soochow gambling task (SGT) demonstrated a reverse finding of Iowa gambling task.^[10] Normal decision makers in SGT were mostly occupied by the immediate perspective of gain-loss and inability to hunch the long-term outcome in the standard procedure of IGT (100 trials under uncertainty). In his book, Inside the investor's brain,^[11]Richard L. Peterson considered the serial findings of SGT may be congruent with the Nassim Taleb's^[12] suggestion on some fooled choices in investment.
