The effect of manipulated success ratios on task preference

The hypothesis that success influences task preferences was tested by subjecting 230 Ss to three different success-failure reinforcement schedules and observing subsequent preferences for the tasks concerned. Success ratios of 85-15%, 70-30%, and 50-50% in tasks dealing with unpreferred stimuli were used. Results supported the hypothesis: the probability of change in task preference was greatest under high success reinforcement ratio conditions.
