Serial data for 268 normal boys and girls were obtained and used to calculate predicted adult statures without using skeletal age. The data can be used to measure physical maturity in 5- to 15-year-old boys and 3- to 13-year-old girls without invasion of privacy or radiological techniques. (Author/PP)

Describes components contributing to memory development, including: (1) capacity or processing allocation features of the information processing system; (2) strategies or control processes for problem solving; and (3) knowledge or semantic features acquired through experiences. Empirical evidence is reviewed supporting the psychological reality of…

Discusses ambiguities in research that arise from the fact that chronological age reflects different components. Considers methodology, components of age as indices of different aspects of development, differential effects of experiences according to their timing, and maturational delay. (RJC)

Examined patterns of psychosocial development for white and African-American traditional-age undergraduate female college students (n=218). Differences were found by class level in measures of autonomy with seniors scoring higher than other classes and mature interpersonal relationship scores indicating a gradual increase. In a measurement of…

Interviews with parents of 87 preschool children within a year of a stuttering diagnosis found that onset tended to occur earlier than was previously thought and was sudden and/or severe in many cases; about twice as many boys as girls stuttered; and there was a positive relationship between severe stuttering and sudden onset.

Delaying school entry for a year is most often viewed as an opportunity for children to mature and develop critical academic, social and emotional skills prior to entering kindergarten. Many teachers view delayed school entry as a kindness to younger, less mature students who need more preparation for the rigors of formal academics in 1st grade.…

Purpose: The purpose of the paper is to compare the performance of distance-learning students in a Small Business Management (SBM) course with that of internal (on-campus) students, and to examine students' demographics and information processing systems for their moderating effects on performance of each student group.…

A suicide potential scale is constructed that fits the Guttman scale criteria. The mean suicide potential scores of various age groups support the cohort model with the exception of individuals 75 and older, where it appears that maturation factors play an important role in explaining suicidal behavior.

Data from the National Survey of Families and Households of 1988 were used to study the predictors of age at home leaving for three groups of home leavers: early, on-time, and late. Predictors vary by age of home leaving. The impact of family structure is strongest for early home leaving. (SLD)

Considered variations in pubertal timing, specifically age at menarche, and association with various antecedents, including heredity; weight and weight for height; stressful life events; family relations; absence or presence of adult male in household; and psychological adjustment, in 75 premenarcheal adolescent girls. Found complex interactions…

Three studies examined naturalistic concepts of moral maturity in young through older adults to develop a more comprehensive understanding of moral excellence than in dominant theories.

This paper examines and summarizes the findings of recent research literature on the effects of color versus black and white learning materials on academic achievement in order to determine if the effect of the color variable is significant enough to warrant the added expense of purchasing colored instructional materials for primary school…

Investigated beliefs about feeling the stares of an unseen other. Found that most adults and young children believed they could feel the unseen stares of another, and across age there were some increases in beliefs about the feeling. Participants believed that in order to feel stares, some cognitive maturity was required. (MOK)

This study examined implicit theories of immaturity among 345 Canadian sixth- and ninth-graders. Qualitative analysis of adolescents' descriptions of an immature peer revealed six foci to implicit theories of immaturity. The majority of adolescents' descriptions focused on childlike behaviors, silly/goofy behaviors, or on mean/hurtful behaviors.…
