Individual Performances in a Single‐cue Probability Learning Task

B jörkman , M. Individual performances in a single‐cue probability learning task. Scand. J. Psychol . 1969, 10 , 113–123. —Inference behavior was studied in a 2 times 2 cue‐criterion task. Fifty subjects were distributed on five conditions varying in cue validity and base rate. They were studied individually with respect to four cognitive strategies: matching, maximizing, double matching and differential maximizing. The utilization coefficients of the average subject had a tendency to ‘overshoot’ when the cue validity was high and to ‘undershoot’ when the validity was low. Double matching and differential maximizing were the most common strategies. Cognitive activity is interpreted as a compromise between various type performances.
