The perceptual-linguistic stimulus distinction for auditory stimuli was examined with 35 trainable and severely retarded (age 8 to 20) and 31 nonretarded (age 3 to 5) students. Retarded and nonretarded students performed similarly on auditory-perceptual stimuli. Nonretarded students performed significantly better than did retarded students on…

Studied the social judgments of children aged 10-15 in Trinidad and in Canada. Ten-year-olds assigned significantly more persons to the positive poles of dimensions. Mid-adolescents applied positive poles of dimensions to persons approximately 62 percent of the time. Discussed findings in terms of developmental implications. (Author/RC)

In a series of experiments, young children were asked to compare the quantities of classes of objects under two conditions: (1) when one of the classes of objects is a subordinate of the other (the traditional class-inclusion problem), and (2) when the terms refer to exclusive sets but different levels of generality.

Analyzes mother and child speech in free play conversation for different semantic and syntactic categories. Based on the study of changes taking place over time in children's use of semantic categories, argues against the hypothesis that the mother's speech is gradually adjusted to the child's performance.

Reviews the formation of space, time, and measurement concepts in children with respect to Piagetian developmental levels and presents some teaching methods to help promote these concepts. (SK)

Describes William Perry's scheme of intellectual development, focusing on the first five stages or positions collectively termed "ways of knowing." Suggests applications of this scheme for science teaching. (DS)

A view is presented that there are people with inborn mathematical talent, and that people with such talent need to receive the best instruction possible. (MP)

The use of interpersonal skills can greatly enhance the learning process, not only by reducing stress, but also by significantly increasing cognitive growth in students. The authors review these findings and discuss their application to teaching in the clinical area. (CT)

The purpose of this study was to identify potential sources of individual and group differences affecting formal thought, and to examine the relationship between the performance of college students on a specific formal operational task and their performance on other cognitive measures identified as possible sources of individual differences.

After some preliminary doubts about Kohlberg's method of assessing moral reasoning, six claims of his "stage-structural" theory are criticized: (1) that the stages constitute structural wholes; (2) their invariant sequence; (3) their cultural universality; (4) their logical necessity; (5) increasing cognitive adequacy; and (6) increasing…

Examines cues which guide the discovery of simple cause-effect relations, beginning with the properties (suggested by Hume) of temporal precedence, covariation and contiguity; explores variables which can influence simple causal judgments; and discusses developmental evidence regarding inference principles associated with causal schemata.…

Several programs deemed good for preschoolers are reviewed, including some that require the child and parent to work the keyboard simultaneously. (MP)

This inquiry had two aims: to assess children's ability to interpret maps in geography; to relate the assessed ability to maturity of thought as proposed by Peel, general intelligence, and age. It was found that performance on four tests depended more on intelligence than on maturity of thought or age. (Author/SJL)

The physical education curriculum offers children an alternative means of communication. It also has the potential to give children a sense of personal worth and control which establishes a basic foundation for self development. (JN)

Presented are findings from numerous studies in terms of a theory which integrates the theoretical position of Piagetian developmental psychology with the concept of the learning set proposed by Harlow. This integrated theory, called the metaset, is offered as a new approach to explaining the efforts of childhood bilingualism. (NQ)
