Three experiments examined preschoolers' and adults' understanding of distinctive semantic functions of adjectives and count nouns. Found that 4-year olds and adults, but not 3-year olds, who heard the adjective version (e.g., "a blue bird") were more likely than those who heard the count noun version ("a bluebird") to choose…

Three studies used illustrated stories to examine preschoolers' understanding of emotional changes when memories of past events were cued by objects in the current environment. Found substantial development between 4 and 6 years in understanding the influence of mental activity on emotions. The strength and consistency of this knowledge was…

Examines the meaning of reaction time (RT) and the possibility that it may predict other cognitive and motor skills in the first year of life. Considers two competing models that specify the information-processing components underlying RT performance. Describes the neural data needed to definitively choose between the models and considers…

Focuses on three main issues emerging from studies of conceptual development: (1) young children's naive theories of the world; (2) how innate constraints in conceptual development work; and (3) how innate and sociocultural constraints are integrated. Maintains that early development of core domains of thought (naive psychology, physics, and…

Investigates the cognitive development of a group of counselor education students (N=43) during their training and also assesses the relationship of cognitive development to actual counseling behavior. Results indicate small incremental gains in counselor cognitive functioning over the course of training. Findings suggest a need to emphasize…

Comparison of elementary grade students with (N=42) or without (N=42) learning disabilities (LD) on their logical-mathematical structures of thought found that, though both groups generated grouping relationships, children with LD tendered to generate solutions showing less coordinated structures of thought. For both groups, scores on the…

Outlines Piaget's late ideas on categories and morphisms and the impact of these ideas on the comprehension of the inclusion relationship and the solution of arithmetic problems. Reports a study in which fourth through sixth graders were given arithmetic problems involving two known quantities associated with changes rather than states. Identified…

The educator's job is, in part, to reorient the student toward the truth and to encourage further cognitive development. Book VII of Plato's "Republic" outlines a curriculum that can orient the student toward truth. The curriculum outlined by Plato still forms the basis of much liberal arts education. (SLD)

Presents a brief history of the development of written language as a means of communication and discusses the characteristics of reading and how this latter activity contributed to the growth of subjectivity. (36 references) (CK)

Two studies of development of spatial representation with two dimensions found that children as young as five years use the same two independent dimensions in fine-grained spatial coding of location in a circle as adults use--radius and angle. The adult pattern, where angle as well as radius is coded hierarchically, emerges by nine years. (HTH)

Examined bias in reasoning in adults and in children, ages five through nine years, by presenting story or videotape true/false messages. Found that adults made judgments contaminated by their own background knowledge abut the believability of the message more frequently than did children. (ET)

Two marble-and-ramp experiments investigated whether a simple-to-embedded-rules account can explain changes in children's causal reasoning. Results indicated that the same difference between three- and four-year olds in the prediction experiment appeared in the action experiment, suggesting that the same rules may underlie causal action as well as…

Compared two-month old's abilities to detect changes in word order for sequences spoken as a well-formed sentence versus two unrelated, but well-formed, sentence fragments. Results suggest that infants are able to remember the order of spoken words when they are embedded within the coherent prosodic structure of a single well-formed sentence. (HTH)

Measured cognitive processing time, imagery skill, and spatial memory span of 128 children and adults, ages 8 to 20 years. Found that performance on spatial memory span tasks was largely predicted by imagery skill, which in turn was strongly linked to processing time; age was much less of a predictor in both cases. (EAJ)

Argues that high school physics should be grounded in motivating contextual activities and connected to a philosophically and historically valid theoretical structure. Explains the large context problem approach and its effect on generating questions and problems. (DDR)
