This paper is a slightly revised version of a contribution to a symposium on the "Biosocial Aspects of Race," held in London, September, 1968; symposium was published in the "Journal of Biosocial Science," Supplement No. 1, July, 1969. (RJ)

Researchers investigated the effects of sex differences on the relationship between conservation ability and the reading and linguistic awareness of five-year-old children. Findings of this study and others consistently support the hypothesis that conservation ability correlates more highly with reading in girls than in boys. (Author/PP)

The performance of 114 New Zealand children of European and Polynesian descent on spatial relations tasks was examined, following their interaction with another child of either the same or different cognitive level. Nonconservers were found to benefit from interaction relative to no interaction more than were partial conservers. (AOS)

Concludes that J. Piaget's cognitive developmental theory may be used as a framework to understand reading in all children, while visual perception showed no relationship to any measure of reading. (FL)

Piaget's theories of cognitive development are applied to the college student and suggestions are given for helping students at different developmental stages. It is proposed that teachers provide experiences that promote cognitive conflict as a means of moving students into new stages. (MSE)

Discusses Piaget's notion of intelligence, characteristics of formal operational thought, and the relationship between formal thought and reading ability. (HOD)

Two studies dealing with length conservation and measurement indicate that caution needs to be used when one looks at and makes claims about children's cognitive ability and development with regard to conservation. (MP)

Seven-year-olds compared successively presented oblique lines which varied as to their position within a square display and their relation to the diagonal axis of the display. Children apparently encoded lines in terms of position and axis features. They used a categorical spatial representational system to compare oblique lines. (Author/RD)

Examined six- and eight-year-old children's use of contextual expectations to detect inconsistencies in story information and their ability to discriminate between information that resolved or was irrelevant to these inconsistencies. Results showed that six-year-olds frequently detected inconsistent events but that they failed to discriminate…

Described is a study which relates Piaget's theory of cognitive development to Lowenfeld's types of perceptual aptitude (i.e., visual v haptic orientation). General interpretations of questionnaire results from university students (N=312) are made that postulate a relationship linking incidence of perceptual and logical ability. (CS)

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…

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)

Results confirmed that children differentially use knowledge of results and suggested that any description of motor skill acquisition must account for the complex interaction between developmental level and the difficulty of the task at hand. (Author/DB)

The article focuses on models of the causal ascriptive processes in relation to the education of exceptional learners. The model the authors found most useful includes four dimensions of causal attributions, i.e., causes vary in the degree to which they are internal, volitional, mutable, and predictable. (PHR)
