Seventy second-grade children who had succeeded on pretests involving liquid conservation observed a nonconserving model and were subsequently retested. Regression to nonconservation was obtained only among some of the children who had been submitted to maximal pressure in the presence of an adult model. (Author/JMB)

Assessed the authenticity of conservation attainment through an observational learning paradigm. First grade children (N=60) were exposed to either a peer or adult model who was either present or absent during a series of tasks. No correlation was found between social influence and observational acquisition of conservation. (Author/JAC)

Appraises the respective contribution of initial competence and of imitation of modeled response in the observational learning of conservation among first grade children. (HOD)

A study was conducted to investigate the respective contributions of personal and social factors (initial competence and imitation of modeled responses) in children's observational learning of conservation. Subjects included 180 first-grade nonconservers from six schools attended by French-speaking middle class pupils. All subjects failed…

Documents cognitive processes mediating the observational learning of conservation. Findings suggest the presence of demand characteristics for high undifferentiated ratings under a public format of certainty appraisal. This contamination prevents valid monitoring of the course of cognitive rule processing. (RH)
