Subjects were first, third and fifth graders of high, low, and average status who were observed during recess. Results suggested the need for additional consideration of contextual factors for a more complete understanding of the entry process. Prior findings from laboratory analogue research appeared to replicate in naturalistic conditions. (RH)

Notes that Grusec and Goodnow's model of discipline encounters as context for children's internalization of parental values seems best suited for middle childhood and adolescence. Suggests that processes such as social referencing, sensitivity to standard violations, emergence of self, and self-regulation may be important antecedents and signs of…

Ancient philosophers, such as Plato and Euclid, believed in an extramission theory of visual perception, which held that there are emissions from the eyes during the act of vision. Three studies, comparing college and elementary school students, found a decrease over age in the belief in extramission and an increase in the belief that vision…

Investigated effects of object reinstatement on event recall by 6- and 9-year olds'. Subjects were interviewed either 10 days and again 10 weeks after an event, or only 10 weeks after an event. Interviewing included free recall, prompts, and questions. Found that age, delay, and object reinstatement all affected amount and accuracy of recall. (JW)

Measures of vocabulary, phonological memory, nonverbal intelligence, and reading were taken from 80 children at ages 4, 5, 6, and 8 years. Comparisons revealed a significant shift in the causal underpinnings of the relationship between phonological memory and vocabulary development before and after age five. (Author/LB)

Mothers in Argentina, France, Japan, and the United States were observed interacting with their 5- and 13-month-old infants. Maternal speech was classified into expressions concerning affect and information. Mothers in all cultures used both classifications with their infants and spoke to older infants more than younger infants. (BC)

One study compared maternal-infant interactions in two samples: Gusii mothers in Kenya and suburban Boston mothers. A second study examined the relationship between mother-infant interaction and maternal educational attainment in Cuernavaca, Mexico. Found that maternal responsiveness was influenced by the mother's cultural background and school…

A total of 30 kindergarten and second, fourth, and sixth grade students from Taiwan and the United States were asked to make category inclusion and typicality judgments for 6 categories. Findings suggested that cultural familiarity with instances plays an important role in the development of category knowledge. (RH)

Examined children's visual self-recognition. Lower-SES maltreated children did not differ from lower- or middle-SES comparison children in the development of self-recognition. Differences between the samples in the quality of affective reactions to mirror self-images were observed. (BC)

Analyzed "if" sentences in conversations in the homes and preschools of four-year-old children. Parents and teachers used "if" more often than did children. Children and parents did not differ in the proportion of "ifs" that had the linguistic properties of a conditional premise. (BC)

Used a cross-sectional natural language database to investigate the parent-child conversations of 3-, 4-, and 5-year olds. Found that 4-year-olds and, to a greater extent, 5-year olds reliably used explicit contrastives. All the children regularly elicited mentalistic responses from their parents and, in some cases, these parental responses were…

Concepts of human differences were studied among 5th and 11th graders in the United States, Japan, and China. Relative to their peers, more American students noted differences in appearance/attractiveness and material resources; more Japanese noted various physical features, and more Chinese noted specific behaviors. With increasing age, Americans…

Used cross-sectional life span data from normative sample for Woodcock-Johnson Psycho-Educational Battery to examine independence of age-related cognitive changes in childhood and adulthood. Found that majority of age-related differences were shared across different cognitive variables and were well predicted by individual differences in…

Collected data on twins' performance on 13 cognitive variables measured three times at three-year intervals. Twins were monozygotic or dizygotic pairs reared together or apart and were in six cohorts ranging in age from 41 through 84 years. Found stable mean cognitive performance across time on eight measures for the younger cohorts, and…

Four studies with kindergarten through fifth graders and adults examined the development of reasoning about the origins of psychological traits. Results suggested an age-related increase in the tendency to distinguish among different psychological traits, and that over time, individuals come to believe that psychological traits are determined…
