Reported are research findings that (1) illustrate the importance of primary spatial orientation for children's and adults' use of symbolic spatial skills and (2) indicate the importance of the distinction between primary and secondary spatial orientation. At least two major ways exist in which humans gather and use spatial information. The…

Discusses the use of visual media as symbol systems that gather, package, and convey knowledge. Media's different and often unique symbol systems are looked at as potentially serving as cultivators of mental abilities. Forty-nine references are provided. (Author/CHC)

Three experiments examined the relation between language acquisition and other symbolic abilities in 18- and 26-month old infants. Infants' ability to learn either words or symbolic gestures as names for object categories were compared across age groups. Findings indicated that infants at both ages learned novel words as symbols for object…

The review surveys theories and models of human development and extrapolates from these to form a composite sketch of the "typical" deaf adolescent. Theories of J. Piaget are examined and the major stages of cognitive development he proposed are summarized. Implications of concepts of disequilibrium and restructuring of cognitive schemas…

Five papers are presented from a 1982 conference on "Developmental and Clinical Aspects of Young Children's Play." In the first paper ("Cognitive Characteristics of Young Children's Play,") S. Rogers summarizes J. Piaget's theories on developmental stages, discusses the relationship of practice play to learning, and then…

This theoretical paper deals with a comparison of the structure and content of primary and secondary thought processes. While secondary processes (cognitive thinking) are effectively dealt with and taught in schools, there is little or no relating to the primary processes (affective thinking). This is due in part to teachers' own difficulties in…

This paper examines the interrelationship between children's acquisition and use of symbols and the development of imaginative play. The paper focuses on the use of pretend play as an expression of the child's capacity for symbolic functioning and as an index of intellectual development. The first section of the paper reviews developmental changes…

This collection of conference abstracts focuses on new directions for research on mental representation and early language development. One page summaries are provided on the following topics: Mental Representation and Initial Language Learning, by Lorraine M. Nicolich; Critical Issues in Language and Cognitive Development, by Roberta Corrigan;…

This paper discusses six aspects of current practice in mathematics instruction of elementary school children: (1) use of symbolization, (2) use of models, (3) consideration of child development, (4) "logical" vs. "natural" approaches, (5) individualization, and (6) diagnosis and prescription. The author argues that symbols are frequently…

Despite considerable work concerning relationships between cognition and language in the second year of life, these relationships remain obscure. Clarification depends on resolution in at least three major areas. First, studies should be expanded beyond the scope of cognitive prerequisite models that have been difficult to conceptualize and that…

To assess the importance of visual attributes relative to acoustic and semantic attributes in children's encoding, a 64-item recognition test was administered to first- and sixth-grade children. Recognition items were linedrawings of simple objects accompanied by aural labels. By manipulating the picture, label, and referent in various…

In a study of mathematics learning, taking a rule-oriented approach, students were taught to trade objects of type A for objects of types B and C. Children ranging from ages 7 to 9 were given rules for converting A to B and B to C and were then presented with the task of converting A to C. Of the 30, 6 succeeded. Of the 24 who failed, half were…

This paper examines sixth-grade children's thinking related to solving ratio and proportion problems before these children had received any instruction in the domain. It explores unitizing and norming, one of the processes identified by both content analyses (Behr, Harel, Post, & Lesh, 1990); Harel, Behr, Post & Lesh, 1990) and research in…
