This study reveals significant differences in the organization of play between the sexes. The primary difference concerns the complexity of the social setting in which play occurs. (Author/AM)

Four features of early adolescent friendship have received the greatest attention in the literature: intimacy of conversations, friends' responsiveness to each other's needs and desires, the degree of similarity or complementarity between friends, and the stability of friendships over time. Each of these features and its potential effect on the…

Tests the ability of 43 children, ranging in age from 20 months to 40 months, to discriminate between pictures of boys and girls and male and female adults. Compares children who passed this gender-task with those who failed it on three behaviors most often categorized as sex-typed: toy choice, aggression, and peer playmate selection. (HOD)

Observed play of 52 toddlers with a set of socially stereotyped masculine, feminine, and neutral toys in a day care setting over 14 months to (1) determine the age at which toddlers consistently exhibit sex-stereotyped toy choices in a natural setting and (2) investigate relation of parents' expectations and the children's own knowledge of gender…

Examined effects of presentation of a peer-in-need stimulus to preschool children in real versus hypothetical contexts, with results indicating a significantly higher incidence of helping behavior in real situations. Nature of helping response as a preoperational reaction to concrete contextual cues is verified. (Author/DST)

A survey of 222 grade school children indicates that sex differences in emotional response to failure might further explain the fact that boys have learning difficulties more often than girls, and that girls' relatively more advanced cognitive development is thought to partially account for the situation.

This study analyzes the Object Categorization Test (OCT) and the Picture Categorization Test (PCT) to provide (1) psychometric analysis of the tests, (2) substantive analysis detailing variation in performance level as a function of age, race, class, and sex, and (3) normative data yielding frequencies of various score patterns. Data was taken…

Examines research which suggests that children's developing knowledge about traditional gender roles has a substantial influence on how children process information pertaining to gender. Evidence also shows that as children attain gender constancy, their behaviors become especially responsive to gender-related information. (Author/RWB)

Investigated the role of behavioral style and cognitive performance as predictors of cognitive development in extremely low-birth-weight children assessed at age 2 and again at age 4. Found stability of cognitive performance from 2 to 4 years of age; this as well as behavior style and orientation-engagement predicted subsequent cognitive…

This study examines the degree to which young children are influenced by the familiarity of an adult participant in their pretend play with toys which vary in resemblance to highly prototypical objects (e.g., cup-like cups or doll-like dolls). A group of 29 children, mean age 21 months, was divided into two experimental groups balanced by sex; 15…

Development in general, and sex-role behavior in particular, is influenced by both biological and environmental factors. However, the coalescence of these factors around the child's growing social cognitive abilities is the critical factor in the development of sex role behavior. (Author/EB)

The development of perceptual, cognitive, and affective perspective taking and empathy was investigated in 96 kindergarten through third-grade children. Cognitive perspective taking was found to increase between second and third grades. Affective perspective taking, in situations controlling for the likelihood of the subjects' projecting their own…

Empirical research on the role of school recess is reviewed. Effects of child-level and school-level variables on recess behavior and the impact of recess on classroom behavior and social and cognitive competence are discussed. It is concluded that recess has important educational and developmental implications. (SLD)

Claims that despite recent efforts to eliminate sex inequities in education, schools continue to provide numerous inputs into the child's gender stereotyping system. Reviews research on sex differences in teacher attitudes, classroom and peer interactions, instructional practices, and other school experiences central to gender schemata…

The purpose of this study was to determine the relationship of method of presentation, grade level, sex, and achievement within grade and sex to the various bases upon which children of low socioeconomic background classify geometric concepts. Two tasks were administered to 96 subjects in the fifth, eighth, and eleventh grades--32 at each grade…
