Four studies examined 10- to 18-month-old infants' ability to detect and encode correlations among features in a motion event. Findings indicated that the youngest infants process static features in an event independently but do not process correlations among dynamic features; the oldest detect correlations between all three features when the…

The complex relationship between cognitive developmental research and children's science curricula is explored, focusing on the tendency to attribute shortcomings in performance to the child's age, the confounding of weak knowledge with developmentally based deficiency, and emphasis of stage-based constraints on children's thinking. (SLD)

A study of 86 children (ages 5-16) investigated the relationship between age, IQ, and preferences for novelty. Children with higher IQs spent significantly more time responding to novel items than lower-IQ children. Older children with high IQs showed the most interest in novel items. (CR)

Effects of type of prompt on the use of external strategies were examined with 272 children (ages 7-17) with or without mental retardation. A task requiring memory for object placement was performed under one of four conditions: no prompt, verbal prompt, physical prompt, verbal and physical prompt. Results suggested that strategy use by older…

The use of rules on nonverbal balance scale problems was studied among 5- to 19-year-olds. Latent class analyses indicated that children used rules, that different rules were used by children of different ages, and that both consistent and inconsistent rule use occurred. A model for the development of reasoning about the balance scale task was…

The study with noninstitutionalized organic and familial mentally retarded and borderline mentally retarded children (N=79) at 2 chronological age levels (mean ages 7 and 10) found no age differences in imitation behaviors in the organic low IQ group and more absolute imitation and recall behaviors in familial low IQ children. (Author/DB)

Forty-eight children aged four and six years listened to stories in which it would be appropriate for the protagonist to feel a negative emotion. Results indicated that six-year-olds were more accurate than four-year-olds in judging that real and apparent emotion would not coincide when the protagonist hid feelings. (RJC)

Examined the relation of infant attention and memory to later cognition in 45 full-term and 46 high-risk preterm infants. Findings indicated a substantial relation between infant visual recognition memory and later intelligence. (RJC)

Studied children's grasp of make-believe transformations they had seen enacted. Children indicated the pretend outcome by choosing a picture depicting no change or a picture depicting the pretend change. Older children chose correctly, even with the addition of a picture of an irrelevant transformation, but younger children did not. Autistic…

Examined how children's and adults' initial conceptions of objects and space influence predictions about the physical world, but lead the naive person to misconstrue a dynamic event. Found that participants proficiently anticipated where an oscillating screen would contact a hidden object, but underestimated the distance until contact.…

Studied frequency and style of help-seeking in 18- and 24-month olds observed at free play and problem-solving. Found that younger toddlers sought less help than older toddlers; both groups sought more help during problem solving than in free play. Older toddlers increased vocal help-seeking whereas younger toddlers sought help through vocal and…

Four experiments with children aged 5 through 12 tested the relationship between short-term memory (STM) and processing capacity. The results suggest that effects obtained with STM span do not provide clear indications of overall working memory development, because STM span and the processing space component of working memory entail distinct…

Examined age-related changes in visual selective attention--ability to resist interference--in children 5 to 12 years old and adults. The interference effect on stimulus evaluation did not discriminate between age groups; however, the interference effect on correct response activation showed a pronounced age-related reduction, suggesting a…

Recent experimental research is synthesized to identify distinctive biobehavioral characteristics of Down's Syndrome persons across their lifespan. It is argued that educational and other intervention programs have not demonstrated strong gains having significant durability or generalization. Recommended is an interactionist function-structure…

Judgments of similarity among mammals, including humans, were elicited from 7 and 10 year olds and adults. Results partially supported a consensus model of shared cultural knowledge. Patterns of deviation from the model appeared between children and adults because of the emergence of a primate category after age 10. (BC)
