The Cambridge Gambling Task226, 227 is a computerized task wherein subjects are asked to place bets on the location of a hidden token. Unlike in other tasks, the odds of guessing correctly are presented to the subject explicitly by varying the ratio of colors among “boxes” that may contain the token, and subjects are free to choose the size of their wager. Common outcomes measured include the speed of decision-making, frequency of making less probable choices, risk tolerance (the mean wager), and risk adjustment (the degree to which subjects vary their wager size based on the parametrically varied explicit odds).
