The present study aims to understand children's behavior within classroom settings in terms of conditioning theories. It was designed based on grounded theory. Data were collected through participant observation and 98 children whose ages varied between 6 and 10 years were observed. Data were inductively analyzed. Findings indicated that…

This study aimed at investigating the similarities and differences between Vygotsky's perspectives on child language development with nativism and behaviorism. Proposing the idea of the Zone of Proximal Development, Vygotsky emphasized the role of collaborative interaction, scaffolding, and guided participation in language learning. Nativists, on…

The purpose of the current article is to highlight the importance of operant techniques in developmental research. Although many researchers employ operant techniques within their individual fields of study, the pervasive nature of these techniques is not often acknowledged in the general literature. The present article describes the history of…

Five adolescents with autism, 5 control participants, and 4 child controls received rewards for varying their sequences of responses while playing a computer game. In preceding and following phases, rewards were provided at approximately the same rate but were independent of variability. When reinforced, variability increased significantly in all…

Two experiments examined whether associating an imitation task with an operant task affected 6-month-olds' memory for either task. Results indicated that infants successfully imitated a puppet's action for up to 2 weeks only if the associated operant task (pressing a lever to activate a miniature train) was retrieved first. Follow-up study…

A study investigating the discrimination abilities of two crib-bound, cerebral palsied, profoundly retarded females demonstrates the importance of individual differences among such children and suggests that discriminative responding may be demonstrated by at least some profoundly retarded children, particularly if distributed practice is employed…

Age-related changes in mental flexibility, in the form of task switching, were assessed in 292 children (58-156 months old). Task switching was examined with a new task for young children, the Switch Task for Children (STC). The STC consists of two easy, comparable games and does not require reading skills, which makes it suitable for children…

Five children with autism and mental retardation learned to discriminate objects in response to spoken names or to match amounts to numbers with a combined blocking procedure. The procedure involved presenting the same spoken word until 10 consecutive correct responses occurred and keeping the left-right location of objects constant. (Contains…

In order to evaluate possibilities of fitting myoelectrically controlled prosthetic arms on infants, this study examined whether 32 infants (1-6 months) could learn to control environmental contingencies by means of contracting the forearm flexor muscle group. Results indicated that older subjects (age greater than 104 days) demonstrated learning,…

This overview reviews a program of interlinked cross-sectional and longitudinal investigations of the nature of cognitive development in infants and young children with Down's Syndrome. The research falls into three groupings: object concept studies, operant learning experiments, and IQ studies. Early results suggest a common learning style which…

Described is a 1972 workshop designed to train Pennsylvania personnel in assessing and programing for low functioning or difficult retardates. State legislation dealing with education of the retarded is reviewed. Considered are assessment techniques in the following areas: motor, communication, cognitive, and social-emotional development and…
