A series of tests of dimensional understanding showed that there was a hierarchical sequence, with three year olds able to handle less complex tasks than four year olds. (Editor)

This article (1) discusses the progression of children's thought from realism to objectivity, to reciprocity, and to realitivity; and (2) describes seventeen types of explanations children give to explain the causality of physical occurrences in the world. (SB)

Despite its failings, Herrnstein and Murray's "The Bell Curve" is valuable for emphasizing cognition as significantly affecting human performance and social achievement; acknowledging human differences; and offering a frightening depiction of contemporary American society. The authors err in reducing intelligence to a stable, immutable…

Elderly men (N=18) and elderly women (N=18) were assigned to three treatment conditions: feedback, practice, or control. Subjects were post-tested on measures of spatial egocentrism, fluid intelligence, perceptual speed, and volume conservation. The effect of feedback was to improve scores on spatial egocentrism, but this influence did not…

Presents a study which assessed preschool children's understanding of "front,""back," and "side" through a variety of tasks. A developmental sequence is defined. (ED)

Described is an empirical and rational inquiry into the formation of a small set of special or geometrical concepts of young children. The approach taken by the author is to attempt to specify intellectual growth in one particular area, a child's acquisition of diagonality, in such a way as to be representative. That is, to give a clean portrayal…

Suggests that although Piaget's psychological theory is developmental and dialectical in a general way, the lack of a developed philosophical basis leads to the subordination of a dialectical approach to static, anti-dialectical concepts. Hegel's theory of interaction and contradiction is examined to show that dialectical theory has a precise…

Explored the relationship between cognitive development and perceptions of environmental press using the Allen (l983) Paragraph Completion Instrument and a version of the Classroom Environment Scale by Moos and Trickett (l974). Persons functioning at varying levels of cognitive development (dualism, multiplicity, late multiplicity, and relativism)…

Describes the initial validation of a new instrument and comprehensive rating manual designed to enhance the accuracy of measurement of the Perry scheme. (Author)

Five measures of intellectual level (IQ, MA, teachers' estimates of intelligence, level of object permanence, and representation of causality) were correlated with effectance variables and with each other for 42 quadraplegics (one to 12 years). Results reveal some relationship between intellectual level and effectance, although cognitive ability…

The author presents a series of programmed exercises designed to help teachers develop the skills necessary to incorporate Piaget's concepts of child intellectual development into effective classroom use. (MB)

Reviewed is research concerning cognitive development of entering college students; the implications for teaching biology and evaluating instructional materials are discussed. (SL)
