| Summary: | The purpose of this study was to determine the effect of irrelevant cues on performance in a multiple-cue probability learning task with binary cues and events. Five hundred ninety-five subjects were assigned to 24 groups in a 4 (validity of relevant cue dimension) × 3 (number of irrelevant cue dimensions) × 2 (replications) factorial design and were run for 400 noncontingent trials. Analysis of the data indicates that (a) the number of irrelevant cues has an effect on performance which diminishes but does not disappear across trials; (b) there is an interaction between the number of irrelevant cues and the validity of the relevant cue, the resultant performance decrement being greatest for relevant cues of moderate validity. A cue selection hypothesis model consistent with the data is briefly outlined. |
