DART -- The Decisions about Risk Task
What is DART?
DART stands for the Decision about Risk Task. We have developed several interrelated versions of DART, but all versions of DART serve the same core function. DART is a computerized task that allows researchers to study people’s decision making under risk and/or uncertainty. It presents research participants with an abstract analogue of situations in which people learn about potential hazards via multiple ways, and then make decisions about how to behave—namely whether to take risks regarding those hazards. An important characteristic of DART is its flexibility for a researcher. The following are examples of key variables that can be manipulated within DART: the number of hazards, the probability of a hazard actually causing harm, the manner in which these probabilities are learned (via description or iterative experiences), the magnitude of harm that a hazard can inflict (potential loss), the potential benefits of risky choices (potential gains), the images used to represent the hazards, and the speed with which decisions must be made. Behavioral choices constitute the main dependent measure in DART, but subjective probabilities can also be solicited in varying forms.
