Second graders were administered a two-choice discrimination task in which irrelevant dimensions were correlated .50, .75, or 1.00 with the 100 percent rewarded cue. Results indicate that learning was most impeded in the .75 condition and was most efficient in the 1.00 condition. These results support the Hypothesis Testing Theory of…

Fifteen autistic and 15 normal Ss were trained to respond to a card containing two visual cues. The children were further tested on the single cues in order to assess whether one or both stimuli had acquired control over their responding. (Editor/RK)

Major finding was that punishment presented in the same sensory modality as the reinforcement was superior to punishment presented in a different sensory modality from the reinforcement. (Author)

Data were interpreted as suggesting that incidental learning may not be cumulative over trials, but rather, may be due to memory of the last trial. (Author)

Results of these experiments are evaluated in conjunction with the hypothesis that frequency information is a dominant attribute in recognition decisions. (Author/MB)

Results indicate that for children in this study's age range orientation is a less salient discriminative cue than either size or color. (Author/MB)

Study found that stimulus presence during a delay of reinforcement interval enhanced performance, and to a large extent prevented the usual delay-produced decrement. (Authors)
