Publication patterns of articles in "Adultspan" from 1999 to 2009 were reviewed. Author characteristics and article content were analyzed to determine trends over time. Research articles were analyzed specifically for type of research design, classification, sampling method, types of participants, sample size, types of statistics used, and…

This study examined the performance of middle aged and elderly adults on the Piagetian tests of class inclusion and multiple classification. (GO)

Determines patterns of differential human development in a longitudinal study of 417 male and 358 female college students ages 18 to 30. Findings suggest individuality in development is associated with significant qualitative individual differences that are best described on a cross-time basis. (BJD)

Formal and familiar materials were used to test Piagetian classification and formal operational abilities in two groups of educated adults: one group aged 30-38 and the other aged 57-82 years. Subjects did not show mastery of the tasks. Results suggest a new model of cognitive lifespan development. (Author/MS)

Although studies using recall tasks to measure memory typically report age-related declines in performance for older subjects, little is known about how these research results relate to performance in actual situations. A study was undertaken to determine whether years of experience in a domain of knowledge could compensate for age-related…

Laboratory education is discussed from three viewpoints: (1) as an instrument for adult resocialization, (2) as an educational challenge which promotes personal but not social reconstruction, and (3) as a value medium which operates against the intellectual and independence modes. Criticism is focused on what the laboratory education technique…

Few studies concerning siblings have taken a lifespan approach, i.e., studying sibling relationships from childhood to old age. To outline the developmental changes that occur in the quality of the sibling relationship during various periods of the life cycle and to test the feasibility of devising a coding system to identify such changes, 47…

The developmental trend from overall-similarity to dimensional-identity classifications is explained by a quantitative model. The model provides good qualitative fits to the extant data. Three experiments examining classifications in 120 2- to 8-year-olds and in 20 undergraduates support specific new claims of the model. (TJH)

A dual taxonomy is presented to reconcile two incongruous facts about antisocial behavior, that it shows impressive continuity over age, but its prevalence changes dramatically over age, increasing almost tenfold during adolescence. Studying delinquents earlier in life may yield more information about the causes and antecedents of antisocial…

On the premise that researchers, practitioners, and policy makers lack an extensive and systematic examination of the concerns of the aging, this monograph examines American social issues as a context for a functional definition of aging and a taxonomy for use in conducting research. Issues are examined with regard to aging and work in four areas…

This book describes and assesses the major theories of career choice and related research. The following are among the topics examined: history of vocational and career psychology (historical foundations; psychoanalytic conceptions of career choice; the Ginzberg, Ginsburg, Axelrad, and Herma theory; Tiedeman's developmental theory; recent history…

This symposium on adult learning and human resource development consists of three presentations. "Adult Learning Principles and Concepts in the Workplace: Implications for Training in HRD" (Margot B. Weinstein) reports on findings from interviews with restaurant employees who reported that training practices using adult learning…
