Reports three experiments conducted to investigate factors controlling performance of nonreinforced verbal imitation. (WY)

The stimulus-familiarization-effect (SFE) paradigm, a reaction-time (RT) task based on a response to novelty procedure, was modified to assess response for novelty, ie., a response-reinforcement sequence. The potential implications of attention for reinforcement theory and learning in general are discussed. (Author/CS)

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…

Color and form preferences of kindergarten, first and third grade Ss were tested using standard two-dimensional geometric forms. (Author)

Study attempts to clarify the attentional versus perceptual learning functions of presence of the discriminative stimuli during delay. (Authors)

Results indicate that the RCR (rehearsal-of-the-correct-alternative response) plays an important role such that when the RCR is inhibited, performance is reduced. (Authors/CB)
