The amount of social pretend play in free-play sessions of small groups of five to seven year olds, and the symbolic features of this play, were noted. Conservation, verbal symbol substitution, and role-playing skills, were assessed as measures of cognitive symbolic skill. Results provide no evidence that these social class differences reflect…

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

Over 1000 out of 4000 preschoolers observed conserved identity of matter over time and roughly two-thirds of the 1000 also conserved equivalence. Follow-up showed no correlation between kindergarten conservation abilities and grade one math performance but significant correlations between equivalence conservation by end of kindergarten and grade…

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)

To investigate whether children who had been in a bilingual instructional program for three years or less would have some cognitive advantages over those in monolingual programs, 96 (50 percent male, 50 percent female) first to third graders from Edmonton (Alberta) were tested in 1979. The children in bilingual programs outperformed their…

The cutoff method was used on longitudinal data in more than one content domain in a study attempting to determine whether the effects of schooling are general or limited. Conservation of number, an informally acquired skill, and mental addition, a formally acquired skill, were evaluated among older kindergarten children, younger 1st-grade…
