This study examined (1) whether subjects of different ages tend to rely on different kinds of visual information when given a choice; and (2) whether the ability to use spatial and identity information accurately in a recognition task changes developmentally. (Author/SB)

The category item production task was used to obtain child norms and to investigate two alternative types of category bias reputedly shown by young children: (a) underinclusion of appropriate items; and (b) overinclusion of inappropriate items. Preschool and grade school children (n=144) were asked to produce verbal responses to four category…

The Bransford and Franks paradigm of linguistic abstraction was used to examine age differences in the nature of stored semantic information. (Author/SB)

This paper questions the assumption that a central processing deficit exists in the speed of performing mental operations by children as compared to adults. Two hypotheses are proposed and data are cited as evidence. (JMB)

Effects of advanced aging on hemispheric organization for linguistic processing was investigated with 24 geriatric subjects. Findings indicated that only the left hemisphere was used in language processing, suggesting that right hemispheric language processing ability is inhibited in the elderly. (Author/DB)

The hypothesis that, when trying to decide whether the person, stimulus, or circumstance is the cause of an event, individuals increasingly select schema-consistent information with increasing age was tested in 106 Turkish 9-, 12-, and 17-year-old subjects. (Author/RH)

Reports two studies of 3- to 12-year-old children's social decision making which were designed to demonstrate that previously shown age differences may result from development of the requisite information-processing capabilities and social-situational factors. Implications for the cognitive developmental influence upon social behavior are…

Examined effects of enforced organizational strategies on the memory of older adults for textual material. Young and old adults sorted scrambled sentences of a prose passage into the correct order. When older adults were required to make an in-depth analysis to sort material, their incidental memory for textual information was approximately equal…

Early developmental changes in children's understanding of causality were examined in two studies of three and five year olds' causal judgments. In both studies, children were asked to judge which of two stimuli caused an observed event across a series of problems providing a variety of alternative cues. (Author)

Discusses how youngsters learn to think in a recognizable adult fashion about political, social, and humanistic issues. Reports on research on the development of political attitudes over the course of adolescence. Concludes that the major difference between younger and older adolescents is the ability of the latter to think abstractly when…

Cognition in the elderly has been widely investigated, but there has been some disagreement concerning this phenomenon fostered in part by differences in instruments used, in data collection methods, and in analytic methods used. This study used Immediate and Delayed Recall data collected by the Health and Retirement Survey housed at the…

Portions of this paper were presented at the meetings of the Society for Research in Child Development, Santa Monica, California, March 1969. (MH)

A total of 120 children between four to eight years of age were administered four sets of visual perspective-taking tasks. Results supported the hypothesis that children's task competence would be a fraction of the number and type of spatial relationships embedded in the stimulus displays. (Author/MP)

Third- and fifth-grade children's abilities to make inferences in the context of reading and understanding a lengthy story were examined. The most critical result was that the younger, but not the older children, made fewer inferences when the component premises for an inference were located in separate paragraphs than when they occurred in the…

Two tasks were used to evaluate the relationship between concept usage and the organization of knowledge in semantic memory for 7-, 11-, 15-, and 18-year-old subjects. (JMB)
