Children who observed a very generous adult model sharing, later shared more than those who observed a very stingy model. The effects of vicarious reinforcement on the amount shared, delivered by either the experimenter or the model alone, were also demonstrated. (Authors)

Co-observer evaluations affected the imitation of older children when they were alone, but not that of younger children. (Author)

The theory of social comparison postulates that the tendency to compare one's performance to others' will decrease as a function of the discrepancy between the quality of one's own performance and that of the comparison person. (Author/MB)

Study was conducted to determine the effect a rule had on a child who was subsequently exposed to conforming or deviant verbalizations and/or behavior displayed by a televised peer model. (Author)

Live behavioral and televised behavioral models were the most effective, and live verbal models were the least effective. The effects of the deviant models were more stable over time than the effects of the conforming models. (Authors)

An investigation of immediate and delayed vicarious reinforcements upon children's imitative self-sacrificing behavior. (Author/MB)

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)

Relevance of cognitive and developmental variables to observational learning and imitation is also discussed. (Authors/MB)

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.…
