Highlights the findings of the study by Pollitt et al. in this monograph that nutritional supplementation has long-term consequences for cognitive development and that the relationship of nutrition to cognitive performance does not fit a main-effects model. Also reviews methodological and conceptual issues unresolved by the study; and discusses…

Responds to commentary on the Pollitt et al. study reported in this monograph. Posits that nutritional insults are sensitive to intervention. Discusses research methodology; methodological issues related to sex differences; the buffering influence of high SES and dietary supplementation against the adverse effects of poor diet and low SES,…

Research results from children's story writing suggest a strong male predominance and strong gender stereotypic thinking in young children. Discusses what it will take for young girls and boys to attain a more equitable view of gender. (Author/JOW)

Revealed that 6-month-old infants are unable to access either an original memory or a reactivated memory after lengthy intervals. Despite the fact that their memory processing is more rapid during encoding and retrieval than that of infants half their age, their facility for accessing an original or reactivated memory is weaker than that of such…

The ability of 31- to 36-month-old children to act in accordance with rules was assessed in 2 slightly different experiments using sorting tasks and knowledge tasks. Taken together, the results of both experiments imply a relatively rapid, age-related change culminating in the ability to systematically execute rules that require access to extant…

Studied 49 3 and 4 year olds in an examination of the effect of type of reward agent on children's discounting. Findings indicated that the combination of a negative valence and a particular social role accounted for the discounting of intrinsic interest. This suggests that social knowledge guides the application of the discounting schema. (SH)

Examines the epistemological bases of general education, arguing that current curricular models generate a static, absolutist vision of knowledge. Advocates a curriculum based on the processes of knowing and of learning skills and concepts--across all domains and disciplines--rather than on the knowledge base itself. (DMM)

The results of four studies involving three to seven year olds revealed that, by age three, some children (1) appreciated conservation of matter despite visual disappearance and the existence of invisible particles; and (2) made use of the particle concept to explain how a particle can continue to exist and maintain its properties despite visual…

In one experiment, most four to eight year olds overattributed knowledge to a preverbal baby who heard an informative message. In a second experiment, six and eight year olds acknowledged differences in babies' and adults' interpretations of a message that was not obviously informative. (BC)

Scottish further education lecturers trained 51 students in thinking skills using the Vygotsky-Leontiev-Luria activity theory. After 13 weeks, experimentals' test scores were better than those of 41 controls, but numbers were less than significant, possibly because of students' and teachers' negative beliefs and assumptions about their ability and…

In one task, preschoolers pretended to use common objects. Three- and four-year olds used gestures in which body parts represented the objects. Five-year olds used gestures that involved imaginary objects. In a second task, preschoolers were asked to imitate gestures modeled by the experimenter. Three-year olds could not imitate imaginary object…

In three experiments, children were asked whether animals, plants, and artifacts that had been damaged could heal through regrowth and whether a person could mend them. Four-year olds realized that both animals and plants could regrow and that artifacts had to be fixed by humans. Three-year olds were less knowledgeable than four-year olds. (MDM)

This study investigated the role of semantic analyzability in children's understanding of idioms with 80 children (kindergarten and grades 1, 3, and 4). Idioms varied in the degree that the meanings of their parts contributed to their figurative meanings. Findings indicated age differences with younger children better understanding the…

Examined a theoretical interpretation of recall as a system in which the influences of memory strength, episodic activation, and output interference must be balanced to maximize recall. Children never recalled stronger words before weaker words. As learning progressed, a weaker-stronger-weaker ordering of recalled words emerged. (BC)

Examined whether active participation in the setup of a trick significantly affected the performance of young (mean 40 months) and old (mean 45 months) 3-year olds on questions concerning individuals' ignorance of and false beliefs about a situation. Results suggest that even young 3-year olds have the ability to understand false mental states.…
