TASK
Cambridge Gambling Task
A behavioral task intended to measure risky decision making by subjects. A token is hidden under one of six boxes that are each one of two colors.Different trials have different ratios between box colors(3:3,4:2,5:1).On each trial,participants choose a color on which to bet.The color with the higher probability (more boxes) is associated with lower potential gains and lower potential losses of points than is the color with lower probability.
