One of the focal points of this study is the investigation of the relationship between rates and types of imitative responding and responsiveness to social reinforcement (approval). Subjects were 96 children (5 to 6 years old) equally divided according to sex and race (Negro and white). Findings indicate that: (1) it seems tenable to assume that a relationship between verbal imitation and socioeconomic level does exist, although the nature of the relationship and the relevance of other factors is still unclear; (2) it might be fruitful to maintain the distinction of verbal and motor imitation as separate classes of imitative responses; (3) it appears that there is a greater difference in the rates of responsiveness between white males and white females than between Negro males and Negro females; and (4) patterns of responsiveness are related to whether the social influencing agent is physically or symbolically presented to the subject. The results were interpreted as indicating the complexity of the multidimensional phenomena called responsiveness to social stimuli. (Author/TA)
