Describes the components of, and theoretical/research bases for, learning cycle pedagogy, which is especially appropriate for the special needs of the middle-school student. Three stages of the learning cycle are exploration, conceptual invention, and expansion. (Author/MKR)

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…

Asserts that several of the assumptions underlying Noam Chomsky's and W. V. O. Quine's theories of language acquisition and development are misleading or false. It is argued, among other things, that children do not "acquire" language, but rather learn how to participate in the linguistic community surrounding them. (99 references) (MDM)

Comments on Moshman's discussion, in this issue, of reasoning as self-constrained thinking, arguing that differences in type of reasoning constraint probably reflect different knowledge bases but do not necessarily imply different processes. The fact that different tasks require different kinds of knowledge does not mean that different processes…

Acquisition of the novel name-nameless category (N3C) principle by 22 toddlers with Down syndrome was studied. Results indicated that the ability to fast map a new word to a category is not available at the start of lexical acquisition. Children who used the N3C principle had larger productive vocabularies than others and had begun to acquire new…

Notes advantages of using dynamic models to understand cognitive functioning: (1) they are specifically intended to represent changes that systems undergo as they evolve; (2) they can capture change in a continuous fashion; (3) they can account for development of behavior that appears orderly at times and disorderly at others, and (4) chaotic…

Reviews Karmiloff-Smith's "Beyond Modularity," suggesting that her work highlights phenomena that seem counter intuitive when regarded from current developmental frameworks, and advocates that understanding them requires more complex perspectives than can be supported by either extreme nativist or domain-general models of cognitive…

Presents findings concerning the role of symbolic play. Assumes that symbolic play has seven functions in the child's development: cognitive, creative, ordering, stimulative, social, expressive, and substitutive. Considers play as a phenomenon that prepares children's abilities through symbolic play. (BAC)

This study, based on a socio-constructivist approach, seeks to help children to develop the cognitive processes of decentration and anticipation. Analysis focuses on observation of children's behavior while playing ball in a group and then on the graphic representation of the actions drawn by the children after each play session. (Author/JKP)

This article reviews the evidence on the relationship between the two brain hemispheres and creative cognitive processes. It concludes that claims about creativity being "in" one or the other hemispheres represent an uncritical acceptance of naive pseudoscientific beliefs about the brain and brain function. (DB)

Four experiments tested three to six year olds' and adults' understanding of animals' growth changes. All subjects understood that animals get larger with age. Older children and adults, but not younger children, allowed for dramatic changes in the size and shape of animals over the animals' lifespans. (BC)

Children between three and five years of age engaged in a procedure in which a puppet competitor chose an object which the children preferred. Fewer than 30 percent of three year olds but more than 80 percent of five year olds knew how to conceal their preference from the competitor. (BC)

Tests and confirms hypothesis that a four-stage process exists in the understanding and use of synonyms, antonyms, and tautologies in children ages three to six. The results of this study challenge widely held theories on cognitive development. (45 references) (LET)

Two studies examined four- and five-month-old infants' behaviors of leaning forward toward, and reaching for, an object placed within or beyond their reach. Infants who did not lean forward showed a decline in reaching behavior when the object was placed beyond their reach. (MDM)

The home environment of nonadoptive and adoptive sibling pairs was assessed using the Home Observation for Measurement of the Environment when each sibling was one and two years of age. Correlations between home environment scores for nonadoptive siblings were greater than those for adoptive siblings. (BC)
