Parity is one source of automatic reinforcement that increases the probability of verbal behavior that conforms to models provided by the verbal community. Parity as a conditioned reinforcer could explain the acquisition of grammar in the absence of direct, explicit reinforcement. This possibility has been explored in previous research on…

From early in life, children learn to perform actions on the objects in their environments. Although children learn from observing others' actions, actively engaging with the material to be learned can be important for learning. This study tested whether instruction that included opportunities for children to be active supported toddlers' action…

There has recently been a growth in interest in the use of video technology in the practice of educational psychologists. This research explores the effects of a video self-modelling (VSM) intervention on the behaviours of a child in mainstream education using a single case study design set within a behaviourist paradigm. VSM is a behavioural…

Young children learn from others' examples, and they do so selectively. We examine whether the efficacy of prior experiences influences children's imitation. Thirty-six-month-olds had initial experience on a causal learning task either by performing the task themselves or by watching an adult perform it. The nature of the experience was…

We investigated developmental changes in the level of information children incorporate into their imitation when a model executes complex, hierarchically organized actions. A total of 57 3-year-olds and 60 5-year-olds participated, watching video demonstrations of an "artificial fruit" box being opened through a complex series of nine different…

Tested a proposed developmental pathway for toddlers' mastery of skills in generating non-ritualized forms of cooperative coordinated action with peers. Studied nonverbal imitative acts among U.S. toddlers and toddlers of the Seltaman people of Papua New Guinea. Found that ready imitation of one another emerged during the same developmental period…

This ethnographic study examined one inclusive early-childhood setting over four weeks. Observations indicated that children with special needs regularly imitated behaviors, words, and skills of typically developing peers, more advanced peers with special needs, and teachers. Individualized interventions were regularly conducted within general…
