Purpose: Assists in the evaluation of decision making mediated by the prefrontal cortex.
Age: 18 through to 79 years
Admin: Individual
Time: 15-20 minutes to administer and score
Sample Reports:
The IGT originally developed to assist in detecting decision-making impairment in patients with prefrontal cortex damage, is a computerised assessment that is carried out in real time and resembles real-world contingencies. Specifically, the task allows examinees to select cards from four decks displayed on-screen. Examinees are instructed that the selection of each card will result in winning money but that, every so often, a card selection also will result in losing money. Examinees are told to attempt to accumulate as much money as possible.

Special Features
  • Several optional settings can be customised by the examiner prior to administration, including:
    - Intertrial interval
    - Number of trials (i.e., card selections)
    - Type of currency
    - Starting amount of money
  • Two export formats are available, enabling flexibility with data management.
  • Import features enable the user to import data from previous versions of the IGT.


Evidence provided by a number of research studies suggests that the IGT is a valid measure. Specifically, the IGT has been used in studies examining decision-making capacity in a variety of populations, including:

  • Focal brain lesions
  • Intact older adults
  • Substance addiction
  • Pathological gambling
  • Schizophrenia
  • Obsessive-compulsive disorder
  • Anorexia nervosa
  • Obesity
  • Chronic pain
  • ADHD
  • Aggression disorders
  • Affective disorders
  • Huntington's disease
