By balancing the spacing effect against the effects of recency and frequency, this paper explains how practice may be scheduled to maximize learning and retention. In an experiment, an optimized condition using an algorithm determined with this method was compared with other conditions. The optimized condition showed significant benefits with…

Psychological researchers should deal with the concrete stimulus-response principles of learning on which behavior is based, and study behaviors that are representative of real life behaviors. The present research strategy has come from two faulty ideas: first, a concern with underlying, inferred mental processes, rather than with actual tasks or…

Twenty-seven kindergarten children were trained on two different double classification matrix tasks in an attempt to determine whether the tasks were hierarchically related. Prior behavior analyses of the tasks suggested that the two tasks shared many components, but that the more complex task had in addition components not included in the simpler…

Studies the effects of anger arousal, displays of aggression, and pain cues on later interpersonal aggression. The hypothesis that symbolic aggression has a cathartic effect is contradicted by the results. Bibliography, table, and graphs. (JB)

The study found that concordance between a rule and a recent model's behavior was most effective in leading to acceptance of the rule, despite a tendency for the subject's to adopt lenient self-reinforcement criteria when given an opportunity to do so. (JB)

Suggests that adults are quicker to learn to match the performance of a model similar to themselves in attitude if he is competent. Similarity of the model interferes with rate of learning if he is incompetent. Tables, graph, and bibliography. (RW)

This paper describes the results of some same-college-age peer tutoring experiments. It is based on a theoretical model that calls for greater satisfaction and performance to result from being assigned the role of tutor than of tutee, and under equitable (status-congruent) rather than inequitable conditions. Same-sex tutoring pairs were formed of…

Examines the effects of the presence and absence of nurturance on children exposed to a model who either verbalized the importance of charity or who acted in a charitable manner. Data suggest that performance has a much greater effect than verbalization, with only nurtured females being affected in the latter condition. Tables and bibliography.…

One threat to the internal validity of coached-client analogue research provided a stimulus for this study of verification of experimental control of role performance. The study contrasts the judgments regarding one client's role performances which are made by both trained and untrained observers. The conclusion is that trained observers yield…
