Understanding the intentional relations in others' actions is critical to human social life. Origins of this knowledge exist in the first year and are a function of both acting as an intentional agent and observing movement cues in actions. We explore a new mechanism we believe plays an important role in infants' understanding of new actions:…

The increased prevalence of autism has created an increased challenge for teachers to incorporate specialized teaching strategies to address the unique educational and behavioral challenges facing children diagnosed with autism. Providing teachers with educational training opportunities will promote such learning. In the academic world,…

Effectiveness of a video self-modelling (VSM) intervention was examined with primary schoolchildren who attended a full-time special education programme for pupils with social emotional and behavioural difficulties and who exhibited inappropriate behaviour during small-group reading instruction. A randomised multiple-probe baseline design was used…

In the first of two experiments, we demonstrate the spread of a novel form of tool use across 20 "cultural generations" of child-to-child transmission. An experimentally seeded technique spread with 100% fidelity along twice as many "generations" as has been investigated in recent exploratory "diffusion" experiments of this type. This contrasted…

To study infant imitation of actions modeled by the mother and by an unfamiliar female, 36 infants ages 12, 17, and 22 months were observed. Imitation was found to vary with the type of action modeled and to increase with the age of the child. (BJD)

Experiment One results indicated that reciprocal imitation is not necessarily reciprocal, but is generalizable. Experiment Two showed that subsequent imitation effects, whether from observing others imitate or from being the target of the imitation, result from a process of imitation of imitativeness.

Attempts to identify deficits in object knowledge specific to the autistic syndrome. Examines the correspondence between sensorimotor and play behaviors and language in mentally retarded and normal children. Determines whether these correspondences are different for autistic, mentally retarded, and normal children.(Author/AS)

Studied the imitation behavior of thirty 14- to 18-month-olds using peer and adult models in an elicited imitation paradigm. Indicated significant memory for 3-step behavior sequences both immediately after modeling and 1 week later compared with baseline performance. Found that children in the peer model group outperformed children in the adult…

This study investigated the effect of singing within the elementary school music classroom on (1) students' preference for one of two performances of the same song and (2) students' ideas of "correct" performance. Seventy-five third and fourth graders were concurrently involved in separate experimental groups. One group was taught to sing…

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…
