Explored the relationship between age and intelligence test performance across race and evaluated the developmental progression of scores and construct validity of the Kaufman Assessment Battery for Children in a sample totaling 2,615 children. No significant race or sex differences were found, supporting the validity of the K-ABC. (JAC)

Proposes a developmental theory of sex differences in intelligence that states that the faster maturation and brain size growth in girls up to age 15 compensates for their smaller brain size so that sex differences in intelligence are very small. Discusses evidence that supports this theory. (SLD)

This study was undertaken to determine the progressive development in movement and movement patterns (coordinated movements of body parts used involuntarily to achieve an objective) of children 2- to 6-years-old, to identify general characteristics which may be studied for appraisal of growth and development, and to study variations in movement…

The present study examined relations between behaviors of mothers and children. The analysis of relations over time suggested that stimulating responsive maternal behavior influenced the child's intellectual development, whereas in the area of social relations the child's behavior influenced the mother.

A 13-part television series called "Freestyle" was designed to see if stereotypes about women and work could be changed and was targeted at fourth- through sixth-graders. "Freestyle's" effects were evaluated among more than 7,000 children in 7 cities who completed identical pre- and post-measures assessing sex-role beliefs,…

Examines perspectives on family influences on child development. Maintains that genetic and biological factors and parental actions/attitudes make important contributions to individual differences. Draws on research on gender differences and conduct disorders to illustrate that parental influence on individual differences within cultures has been…

Erik Erikson concluded that differences in the play constructions of young children are largely determined by psychosexual differences in the subjects and not by cultural influence. He suggested that additional observation of younger and older subjects could determine whether the differences were true for all ages or whether they were restricted…

Examination of 71 American Indian and 149 White children from grades three through six on an open self-description measure and a transformational measure of self-concept reveals differences between the groups on specific external, behavioral, and internal attributes of self-concept. (Author/BJV)

Study supports the hypothesis that boys and girls, at the time they enter school, do not show the sex-related patterns of fantasy that have been found to differentiate adult men and women. By the age of about 9, sexual differentiation in fantasy patterns is clearly evident. (Authors/CB)

Three experiments explore factors associated with the development of certain symbolic abilities (verbal, maplike, and mathematical) in 4-10 year old Negro and white children. The experimental tasks required a synthesis of concepts with symbolic stimuli. (MH)

Developmental record ratings were obtained for 200 institutionalized mentally retarded children (5-19 years old) over a three-year period. Results indicated that differences in measured intelligence are associated with differences in developmental behavior and that between the ages of 7 and 20 years the relationship is a linear one.

Investigates developmental change and gender differences in sympathy and personal distress reactions in children. Examines interrelations among indexes used to assess sympathy and personal distress. (PCB)

Investigates the representative frequencies of aggression of 43 children at the ages of 2 and 5 years. Dimensions of physical aggression at age 2 predicted dimensions of physical aggression at age 5. Frequency, initiations, and average length of aggression decreased between 2 and 5 years of age. (RJC)
