Studied developmental changes in optional shift discriminations using kindergartners, second graders, sixth graders, and college students. (DR)

A schema is best understood as a statistically defined concept. Schematic concept formation consists of abstracting the common elements or properties of a defined class in a schema. Thereafter, both discrimination and retention are facilitated, since only deviations from the schema need be processed for any particular class exemplar. In the…

A study was initiated with 60 blind children (kindergarten through grade 2) in order to validate the order of a sequence of tactual discrimination tasks leading to the use of braille and the Optacon. Ss were tested with tasks designed for the readiness level (discrimination of large solid geometric shapes, flat puzzle pieces, embossed dot…

This study examined variables related to problem-solving approaches of young children, using the theoretical framework provided by Zigler and his collaborators in their work on outerdirectedness. Four aspects of outerdirectedness were examined: developmental trends, effects of different types of reinforcement, effects of task difficulty, and pride…

THE DEUTSCH INTERVENTION MODEL IS BASED ON THE THEORY THAT ENVIRONMENT PLAYS A MAJOR ROLE IN THE DEVELOPMENT OF COGNITIVE SKILLS AND OF FUNCTIONAL USE OF INTELLECTUAL CAPABILITIES. DISADVANTAGED CHILDREN HAVE INTELLECTUAL DEFICITS WHICH MAY BE OVERCOME BY USE OF MATCHED REMEDIAL MEASURES. LANGUAGE SKILLS AND MOTIVATION CAN BE IMPROVED BY TEACHING…

Piaget's model of children's conceptual learning and development was compared with Klausmeier's Conceptual Learning and Development (CLD) model in a longitudinal study. The CLD model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known…
