Abstract
266 Ss were given seven different kinds of familiarization training with complex stimuli, each having only one discriminating attribute. Those familiarized with the stimuli used during PA learning had fewer learning errors than the controls. Although a significant over-all effect also was noted, sub-comparisons revealed that differential reinforcement of the discriminating stimulus cue, during familiarization, was superior to reinforcement of non-discriminating cues only with the control stimuli. The corresponding result with the learning stimuli was in the same direction, however, and no interaction was noted. The former result supported certain other predifferentiation studies; the latter findings were harder to explain, but were tentatively attributed to asymptotic conditions.
