A neuropsychological assessment designed to measure decision-making, impulsivity, and risk activity in an individual. In the problem, participants are presented with a series of bets associated with red and blue boxes. They need to choose one of the boxes, deciding whether to bet on a particular color, based on their perception of the probability that a particular color will be chosen. The problem has two main components: the probabilistic reasoning phase, where the participant estimates the probability of an outcome, and the decision phase, where they bet on that outcome. CGT is particularly useful for assessing executive function and impulsive decision-making in people with conditions such as attention deficit hyperactivity disorder (ADHD), addiction, and frontal dementia. The test helps to understand how a person balances between reward sensitivity and risk avoidance, and helps clinicians understand how a person’s cognitive and emotional systems affect their decision-making behavior.
