Abstract: | The theoretical, procedural, analytic, and interpretive components of Poulson's (1983, Journal of Experimental Child Psychology, 36, 471–489) study were considered in an effort to clarify the distinction between social reinforcement and social elicitation. Contrary to Poulson's contention, DRO was not, and cannot by definition be, a control for reinforcement. More importantly, the speciestypical, social nature of the infant probably reflects the collaborative influence of elicitation and reinforcement. By carefully unravelling these two interacting processes, future conditioning studies might specially enhance our knowledge of early social development. |
