In this study, 48 third-grade children learned a successive, two-choice discrimination under one of three conditions: (1) immediate reinforcement (IM), (2) 10-second empty delay (ED), and (3) 10-second delay with the discriminative stimuli in view of S (FD). The performances of groups IM and FD were only marginally different, and were both…

The effects of meaningfulness of the stimulus materials and the presence or absence of contextual cues on problem-solving behavior were investigated. Third-graders (N=80) were randomly assigned to one of four conditions and their performance in a series of discrimination problems was observed. Subjects in Conditions I and II responded to stimuli…

Competence in action perception seems to be achieved very early in life. Because research has indicated that competent perceivers of action must be able to discriminate breakpoints in behavior, then recognition memory for breakpoints should be superior to that for nonbreakpoints at all ages where competence in action perception exists. Two studies…
