Two experiments were designed to detect frustration phenomena hitherto only observed in subhuman animals, frustration being defined as the omission of the response item after a correct anticipation in a partial reinforcement schedule. (Authors)

Affect arousing and energizing properties of positive and negative reinforcing stimuli were investigated. Subjects received positive evaluations (PE), similar attitudes (SA), dissimilar attitudes (DA) or negative evaluations (NE) presented on slides. Pre- and post-slide semantic differentials were filled out by each subject. All subjects then…

Results indicate that responses are not organized per se, but that response grouping is mediated by stimulus categories. (Author)

Reinstatement is the increased retention of previously learned behavior. (MB)

The effects of aural and pictorial elaborative prompts were estimated separately for response and associative phase components of children's noun-pair learning. Indices of response learning revealed equivalent effects among prompt conditions whereas measures of associative learning demonstrated substantial performance facilitation as a function of…

Results support the importance of the passage of time during learning as the crucial factor affecting high-arousal recall. (Author/MB)

Purpose of this experiment was to investigate the relationship between stimulus recognition and various learning conditions which were designed to affect both stimulus encoding and associative learning in a paired-associate task. (Authors)
