One solution to the problem of getting expert knowledge into expert systems would be to endow the systems with powerful learning procedures that could discover appropriate behaviors by observing an expert in action. A promising source of such learning procedures can be found in recent work on connectionist networks, which are massively parallel…

Investigates ability of nine-month-old infants to imitate simple actions with novel objects. Looks at both immediate and deferred imitation. Findings show that imitation in early infancy can span wide enough delays to be of potential service in social development. (Author/RWB)

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…
