Employing a child-centered approach to the growth and development of children from birth to age 16, this book describes in detail the personal, social, and intellectual development of children as they progress from infancy through adolescence. It contains anecdotes and examples that capture the unique qualities of each age and stage of child…

Explores age differences (6 to 22 years of age) in conceptions about the nature of the skills required by verbal and nonverbal (abstract) intelligence tests. (HOD)

With specific attention to appropriate teaching strategies, the author defines a developmental stage theory of children's interest in and psychological uses for knowledge. The four stages are: mythic (up to approximately age 9/10); romantic (ages 9/10 to 15/16); philosophic (ages 14/15 to 20/21); and ironic (adult). (SJL)

In an incidental memory task, second, sixth, and tenth-grade students performed three orientating tasks on different subsets of items in a list of common nouns. In one condition (EPA), children judged words on the Evaluative, Potency and Activity dimensions of the semantic differential. In another condition (EEE) children made phonetic judgments.…

Raw scores on WISC-R subtests and the verbal, performance, and full scale IQ scales were correlated with age separately for White and Black males and females. The relationship between age and intelligence test performance was constant across race and sex and supports the construct validity of the WISC-R. (Author/RD)

This paper reviews studies in which scores on Piagetian tests of logical thought were correlated with IQ, mental age (MA) and chronological age (CA), and examines the possible effects of the size of the age range and mean age of subjects on these correlations. The data included 44 groups of subjects obtained from 36 studies in which Piagetian and…

Confirmatory factor analysis of data from a portion of a long-term study provided evidence for two components of math anxiety for 298 male and 266 female 6th through 12th graders. The components related to negative affective reactions and cognitive aspects. Age and gender differences were significant. (TJH)

This study of 28 girls (ages 2-19) with Rett Syndrome found profound handicaps in the intellectual and adaptive areas, according to standardized tests. Subjects seemed capable of learning some self-help skills at a basic level. The Cattell Mental Age was significantly negatively correlated with chronological age. (JDD)

This report presents results from three research studies that were designed to explore both the definition and the structure of the adaptive behavior construct. The first study investigated the structure of adaptive behavior as a function of age, developmental level, and type of handicap through an exploratory factor analysis of both the…
