Investigates expression of part-whole semantic relation by children 3 to 12 years old and indicates that older children prefer its use significantly more often. The part-whole semantic relation was also observed to take several linguistic forms, such as partitive, spatial, and possessive. Age, experimental task format, or type of experimental…

A group of young and elderly females were tested on a paired-associate task. The results indicated that older individuals made more intrusion errors on the CVCs high in AV on the Glaze norms but low on the Archer norms. (Author)

Two studies compare cognitive maps generated by first and fifth graders and college students. One study utilized a triangulation task, the other two used imagined situations. A practical methodology for such studies is introduced and a way of conceptualizing cognitive map development is suggested. (MS)

This study was undertaken to determine the relative contribution of age, sex, and three stimulus features (board shape, block arrangement, and block shape) to perceptual accuracy on 39 board/block adaptations of Piaget's three-mountain task. (Author/SB)

Field trips are a regular part of many programs for young children. Field trips can serve a variety of purposes, such as exposing children to new things or helping children to see familiar things in new ways. The purpose of this study was to learn the meaning children gave to a field trip. Cameras were made available to each of the children in a…

This report discusses the outcomes of a study that examined 216 comparably aged children and adolescents (ages 2-18) with fragile X or autism to determine whether longitudinal change in cognitive ability and adaptive behavior was similar in the two groups. Results found decreases in Intelligence Quotient scores in young children with fragile X as…

Assesses the relative importance of synonymity and antonymity for memory encoding of words for second and sixth graders. Also, the variable of association strength is investigated for both groups through the presentation of false-recognition stimuli. (DP)

Suggests that the information integration processes used by adults to form judgments are also used by children. (ST)

An extension of discrimination-learning theory based on the inhibition of stimulus intensity was proposed and supported as a mechanism of cognitive development. Among 48 normal and 37 educable mentally retarded children the predominant category of transistional children conserved at a low level of stimulus intensity but failed to conserve at a…

In a schematic concept formation task, second and fifth graders were required to sort 60 computer-generated, 8-sided polygons into two classes. The results indicated that age differences in schematic concept formation are due more to the efficiency of information use than to differences in strategy or the selection of information to be used.

One hundred sixty sibling pairs from two child families were sampled for sibling interaction behaviors as they relate to measures of categorization style. The study provides additional evidence of the importance of a child's siblings to his cognitive development. (Editor/RK)

Studies based on an analysis of one species of learning and transfer task, the transposition problem, in terms of two ways in which the experimenter's and the child's definition may differ. (Author)

Results indicated that Piagetian developmental level significantly predicted problem-solving performance, whereas level of field independence did not appear to clarify individual differences in a meaningful way. (Author)

A theoretical framework stemming from the evolutionary psychology of Herbert Spencer, along with two experiments with young children as subjects, are presented. (Authors)
