Research in progress on some unresolved issues regarding the relationship of cognitive development and language acquisition is reported, especially the relationship between conservation of length and knowledge of relevant comparative dimensional adjectives. Much further investigation is recommended and possible educational implications are…

Educable mentally retarded (EMR) children were presented an item selection task to assess their sensitivity to orthographic structure in printed English words. Analyses of performance indicated that EMR children do acquire implicit knowledge of orthographic rules and that this ability is related to the development of reading skills. (Author)

Research concerning cerebral asymmetry and its effect on scholastic achievement, reading disabilities, learning disabilities, and linguistic competence is reviewed in an exploration of brain hemisphere-specific etiologies of dyslexia. (CJ)

Studied adults (ages 20-79) presented with two types of problem-solving tasks: a typical task used in problem-solving research, and a task composed of practical daily life problems. Results indicated that developmental function depends on the type of problem presented, while performance on abstract problems may decrease with age. (Author)

Investigates adolescents' perceptions of impressions held about them by important others, focusing on cross-sectional differences from early to late adolescence in the structure of social self-conceptions, on differences between parental and peer social self-conceptions and between individual and social self-conceptions, and on adolescents'…

Imitation by infants functions in two ways: (1) to help the individual understand a puzzling event, and (2) to indicate mutuality with another person. Although changes in cognitive understanding influence the course of imitation, the occurrence of imitation in specific situations may be governed by the interplay of the two functions that imitation…

Children's abilities to judge "who is older" without using size as a cue were studied. Five-year-olds were better able to discriminate age than four-year-olds but were not equal to adults. No significant sex differences were found. (Author/RD)

Three experiments were conducted to examine children's use of multiplying and proportionality rules in judgments of area. In the first two experiments, 7- through 8-year-olds were asked to judge the area of rectangles. In the third, 8- through 11-year-olds were tested on ratio of a rectangle compared to a horizontal line. Results indicated…

The hypothesis that overall-similarity relations structure both adults' and children's classifications of heterogeneous objects (objects that differ in a variety of ways) was supported in two experiments. When objects varied simultaneously on many dimensions, adults and children constructed classifications that maximized within-category similarity…

Describes project SWING (Starting With Individual Growth), a comprehensive preschool education program for children at risk of a wide range of learning or social difficulties. (Author/RH)

Depressed outpatients received treatment focusing on interpersonal skills, cognitions, or pleasant events. Patients received immediate treatment or delayed treatment. All treatment modalities significantly alleviated depression. All patients improved on most dependent variables, regardless of whether variables were directly addressed in treatment.…

Four-year-olds succeeded in making comparisons between sets of objects when comparison questions called for comparing set with set or subset with subset. However, when comparison questions called for comparing set with subset, the children failed to complete such tasks successfully. (Author/DB)

Summarizes research done in the 1950s, early 1960s, and mid-1970s about how children and adolescents think about economic related ideas. Economic reasoning develops in a stage-like manner similar to Piagetian stages of cognitive development, becoming more abstract, other-directed, and flexible with increasing age. (RM)

A hierarchical factor solution was obtained from a psychometrized battery of Piagetian-type tasks individually administered to 660 kindergarten children. The first two levels of factors included Piagetian theoretical entities. A third level factor was identified as a g. The association of Piagetian tasks with academic achievement was through the g…

Proposes the cognitive developmental paradigm for developing and teaching career development courses in secondary schools. Proposes the major Piagetian constructs of interaction, equilibration, assimilation, and accommodation as a means of intervening in both the structure and function of the career thinking of adolescents.
