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…

As age and grade increased, recall on all tasks increased; subjects in grades three to six were also seen to have a fully developed Iconic Memory, while only sixth graders had a functionally developed Immediate Memory. (KR)

This paper discusses how children form concepts; the diversity of concepts that are influenced by social processes; factors that affect concept formation; and behavioral techniques that have been effective in improving the instructional capabilities of parents and teachers. (Author/AM)

Inferential questions were found to elicit longer responses than factual questions, reflecting complexity and the use of higher cognitive processes. (MKM)

This experiment was designed to determine whether children's inability to discriminate mirror-image oblique lines is a function of encoding in memory the left-right orientation or the degree of slope of an oblique line. (Author/SB)

Twenty subjects at each of four age levels (8, 10, 12, and 18) rated linguistic units of prose passages in terms of their importance. Third- and fifth-grade subjects did not differentiate items in terms of their relative importance to the text and at all ages such judgments were related to recall. (Author/JMB)

It was hypothesized that Piaget's argument on behalf of the reorganization of cognitive processes would gain empirical support from a color/form, matching similar objects problem for 52 6-year-olds from a variety of socioeconomic backgrounds. (Author/MS)

A series of three experiments was conducted to verify the hypothesis that age differences in paired-associate learning proficiency across adolescence stem from the development of increasing eleaborative propensity. (Author/JMB)

The Neuro-Cognitive Education Project (NEP), a cognitive reeducation program for the head-injured child, was evaluated. Results indicated differential increases on certain measures of adaptive functioning among the intervention group but little improvement in cognitive functioning. (DB)

Examines Kail's argument that similarity in developmental speed-of-processing curves for name retrieval and mental rotation indicates that performance on a wide range of cognitive tasks is constrained by growth of a central limiting mechanism. Results suggest that operation of this mechanism is neither sufficient nor necessary to generate the…

Examines developmental change in 4- 7- and 10-month-old infants' perceptions of correlations among attributes to determine whether relational information plays a role in abilities ranging from the perception and recognition of a simple pattern to the formation of a category. (HOD)

Tests children for the effects of prior knowledge on the amount of learning that occurs after a training period focusing on either number skills or logical operations. No relationship existed between the amount children learned and their pretraining knowledge or the amount learned and their developmental level. (Author/BB)

Examines kindergartners' and second graders' knowledge of concept attribute importance and the children's use of this knowledge to categorize. (HOD)

Describes four experiments that examined the ability of second- and fifth-grade children and college adults to use "extra-list" cues to retrieve episodic information from memory. Shows that effective cue use varied with both the "match" of cue and event classification, and with the associative structure of permanent memory.…

A program is described that is designed to improve the cognitive planning abilities and social skills of students nine to 16 years old with behavior problems. Students learn the cognitive planning sequence of stop, plan, do, and check. (CL)
