Balloon Analog Risk Task

Basic Characteristics

  • Description

The Balloon Analog Risk task is a computer based assessment of risk taking behavior. A subject uses a computer mouse click a balloon pump that inflates a balloon on the screen. Participants are not given any detailed information about the probability of the balloon exploding. Each pump of the balloon without its' explosion places money into a money reserve. Should the subject pop their balloon they lose all money and another balloon appears. At any time during a trial the subject can click "collect money" and transfer all money from a temporary bank account to a permanent account where a new total is updated. Subjects are informed that the objective of the task is to get the largest amount of money possible while avoiding balloon explosions.
