Notes that sorting is an early classification activity; as language develops, objects can be sorted by various attributes and described. Describes key experiences in this developmental sequence, and provides guidelines and specific suggestions for selecting for classroom use "attribute materials" designed to lead students to both…

Examined the nature of sociocognitive growth in 66 kindergarten and first-grade children by having pairs of children work together to solve spatial perspective-taking problems. Found that the entering performance composition of the dyads did not affect cognitive growth, whereas the construction of shared cognitive experiences in which children…

Analyzed the influence of a comprehensive program of nurse home visitation on the intellectual functioning of children born to women who smoked cigarettes during pregnancy. Found that comprehensive home-visitation services before and after delivery can offset the impairment in intellectual functioning associated with substantial maternal smoking…

This study evaluated the Bielefeld Developmental Test for Blind Infants and Preschoolers by comparing cognitive performance of blind and sighted children (ages three and four). Results indicated that even this test (with "blind-neutral" items) did not permit a fair comparative assessment, though it did prove suitable for within-group…

Reports results of 14 studies on children's knowledge about thinking. Suggests that preschoolers appear to know that thinking is an internal mental activity that can refer to real or imaginary objects or events. However, preschoolers are poor at determining when a person is and is not thinking. This shortcoming is considerably less evident in…

Reports on research that showed that preformal-operational fourth graders could indeed benefit from classroom writing instruction on the higher-order skill of persuasive writing. (SR)

Argues that Vygotsky's "zone of proximal development" (ZPD) can be redefined as a nonlinear dynamic model. Presents a mathematical reformulation that generates a variety of developmental patterns and has the capacity to show under which conditions unwanted or unsuccessful developmental paths may occur. Illustrates how this reformulation…

Notes that Halford's book does not really address children's own understanding but rather the psychologist's attempt to understand children from the outside. Discusses the five major sets of ideas at the core of Halford's explanations of capacity, complexity/dimensionality, development, and learning. Examines two arguments against Halford's…

Comments on Gauvain's discussion, in this issue, of the development of thinking from a sociocultural perspective, expanding her analysis by comparing research on apes who have developed in natural habitats with apes raised by humans in something resembling a human culture. Argues that the study of nonhuman primates can contribute to the emerging…

Examines children's comprehension and learning of expository texts on micro-, local-, and global-level processing skills. Finds a gradual increase in higher level processing skills with age. Notes that critical developmental patterns from nine-year olds onward took place in local- and global-level processing. Finds that developmental patterns were…

Investigates the relationship between cognitive abilities at age four and reading at age seven. Shows that reading ability was positively correlated with knowledge of grapheme-phoneme correspondence, visual memory, auditory sequential memory, and Draw-a-Man scores (intelligence). Suggests that cognitive deficits predate reading problems. (PA)

A study investigated the extent to which 210 college students' learning orientations were shaped independently and jointly by their academic and nonacademic experiences. Findings indicated that the two kinds of experience each made statistically significant and unique contributions to gains in intellectual orientation after controlling for…

Argues the good and the bad aspects of constructivism as revealed through the literature, and describes the framework of the three different dimensions constructivist writers fall into. The author also discusses the degree to which each dimension harbors various sociopolitical versus educational concerns. (GR)

Suggests that the ability to process narrative information is fundamental to understanding human psychological development. Notes that a culture's system of understanding and interpreting the world is carried mostly by stories and texts. Explores how narrative understanding can be modeled in Fuzzy Trace Theory by using the principles of this…

A conceptual framework of cognitive growth is sketched and a mathematical model of cognitive growth is presented with the conclusion that the most plausible model is a model of logistic growth with delayed feedback. The model is transformed into a dynamic systems model based on the logistic-growth equation. (SLD)
