Task assessing probabilistic weather prediction (Knowlton, Squire, & Gluck, 1994). On each trial, participants view between one and four visual cues and must predict a binary outcome (“sunshine” or “rain”). After they make their response, feedback is given as to whether their choice was correct or not, and then the next trial occurs. Each combination of visual cues has a particular probability associated with it relating to the weather outcome. The chart on the right shows the probability of sunshine or rain for five example combinations of cues (1 = present, 0 = absent).
