The "Digest" has been issued annually except for combined editions for the years 1977-78, 1983-84, and 1985-86. Its primary purpose is to provide a compilation of statistical information covering the broad field…

Two experiments involving 46 seventh graders, 28 undergraduates and 28 seventh graders examined developmental and individual differences in students' revising for meaning. Results of both experiments suggested that knowing error location (having it pointed out) may focus less sophisticated writers, like middle school students, too narrowly and may…

Investigated different age groups' knowledge of developmental norms of children. Collected data from 280 midwestern university students through a questionnaire. Results showed that knowledge of normal development was both over- and underestimated regardless of age of student or year in school. (BH)

To study graphic representation in different cultures, 1,279 children, adolescents, and university students from English, Hebrew, and Arabic language cultures produced graphic representations of spatial, temporal, quantitative, and preference relations in three experiments. Findings are discussed in relation to subjects' age and language culture.…

This paper argues that instructors of child development should use literature to supplement theory and research in their courses. It is argued that literature elucidates psychological concepts with real life examples while deepening students' appreciation for the complexity and diversity of human development. Particularly effective in achieving…

Maintains that medical growth charts that have been created by pharmaceutical companies can be utilized to demonstrate a variety of statistical concepts in psychology.

Investigates the changing voices of boys in the fifth and sixth grades. Categorizes their voices by J. M. Cooksey's changing voice stages and uses his criteria for determining stages (highest and lowest pitches sung, overall range, and pitch of the speaking voice). Results indicate an earlier voice change than previous research. (CMK)

Six experiments involving 279 2- to 5-year-old children, 52 undergraduates, and 16 adults examined the interaction of perception and language in the development of magnitude marking of size, loudness, and achromatic color. Results suggest converging interactions between perception and language for size and loudness and antagonistic interactions…

A stratified random sample of 82 subjects, from 4 to 25 years of age, was used to examine relationships between intransitivity of paired-comparison relationships and age of subjects. Results indicate a floor level, at 6 to 7 years of age, below which response intransitivity increases significantly. (TJH)

Compares the reading and comprehension ages of children who were in Reading Recovery at age 6 to those in a comparison group as they enter their fifth and sixth years in school. Reports that the ex-Reading Recovery children were 12 and 13 months superior in terms of reading and comprehension ages, respectively. (CMK)
