Studied gender effects on false belief development among children ages 2 to 6 years. Found a slight advantage for girls on false belief task performance in both datasets that was apparent in younger but not older children. Language ability could be controlled only in a small subsample and cannot be ruled out as a mediator to this effect. (JPB)

Examined age and gender differences regarding the nature, meaning, and function of cherished possessions. Among the significant differences found were that younger children were egocentric in meanings assigned to cherished possessions, whereas older children held social relationships meaningful; females favored items to be contemplated, while…

Examines influences of peer relations on the development of social and cognitive competence. Discusses implications of differences in boys' and girls' play styles for cognitive skills and the development of intimacy. Notes that gender segregation is initiated and maintained within the peer group. (BAC)

Sex differences in the behavior of infants may have the potential for eliciting differential treatment from adults, regardless of whether or not adults consciously intend to encourage sex-differentiated behavior. The role of biologically-based sex differences in partially determining cognitive development is discussed. Availability information is…

The authors bring together findings from research dealing with the effects of father absence in children's development. (WY)

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…

The objectives of this study were (1) to observe and describe the social quality and the cognitive type of spontaneous play exhibited in a group of 20 children in a child care setting during two age periods, toddler (14-30 months) and preschool (30-48 months), and (2) to chart the developmental trends using a model of play complexity derived from…

This document reports a study investigating the effects of father absence on measures of cognitive, social, and motivational development in infancy. The sample included 54 black infants, 27 of whom were classified "father-absent." This classification was based on two indices, (1) a dichotomy of father-absent or father-present based on…

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…

This study was undertaken to determine the relative contribution of age, sex, and three stimulus features (board shape, block arrangement, and block shape) to perceptual accuracy on 39 board/block adaptations of Piaget's three-mountain task. (Author/SB)

To investigate the development of preschoolers' social-cognitive play behaviors, ten preschoolers (two, three and four years old) were observed in their classrooms on 15 occasions by a time-sampling schedule. Social-cognitive behavior coding (Parten and Smilansky) indicates that children's play became more social as they grew older. (Author/PN)

A study of 700 children (ages 5-12) investigated whether children's conceptions of and expectations of friendship are determined by chronological age or by mental age. Results found children of differing intellectual abilities pass through the five conception stages of friendship at different ages and at different rates. (Contains 4 references.)…

This longitudinal study examined the interrelationship between sex of the child and sex of the parent on the expression of attachment behaviors during the child's first 2 years. Special consideration was given developmental changes in the attachment structure and the relationship of attachment to cognitive development. Ten boys and 10 girls were…

The relationship between understanding of friendship and asociality was examined in 91 girls and 104 boys, ages 9 to 17 years. Understanding friendship was significantly related to age and sex. Difficulty in understanding components of friendship appears to be one correlate of boys' delinquent tendencies. (Author/BS)

This study aimed to assess cognitive and behavior correlates of young children's interest in computers. Computer users tended to be older and exhibited significantly higher levels of cognitive maturity than nonusers. Other findings are discussed. Results suggest there are important cognitive underpinnings for computer involvement by preschoolers.…
