Intraindividual variability (IIV) in cognitive speed, or moment-to-moment changes in ability, is a developmental phenomenon indicative of neurological integrity that increases gradually across adulthood. Past research has shown that IIV negatively covaries with cognitive performance, in which higher IIV at one occasion is associated with poorer…

Assessed adults (N=88) on tasks operationally defining short-term memory structural limitations and process abilities. Although a number of minor chronological age-related differences were noted between monaural and dichotic word list performances, the findings indicated both structural capacity and organizational strategy deficiencies over…

A developmental theory of adult intelligence is proposed called PPIK. The PPIK theory integrates intelligence as process, personality, interests, and intelligence-as-knowledge. Data from the study of knowledge structures are examined in the context of the theory and in relation to measures of content abilities. (SLD)

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

Examined age differences in self-ratings of present and projected past and future cognitive performance across cognitive domains. Findings from 151 adults in their 20s, 40s, 60s, and 80s revealed that performance on fluid/speeded intelligence, memory, and reasoning tasks followed progression of poorer performance with age. Found age differences in…

Evidence on the impact of noncognitive factors on the cognitive performance of young and older adults is reviewed. Cohort-associated modifiers, motive states, task and measurement factors, and environmental effects are related and account for age differences in cognitive performance. Areas of research pertinent to educational psychologists are…

This paper presents a model of cognitive development across the life span that is designed to integrate the diverse empirical evidence in the area of cognitive development in childhood and adulthood. Relevant research is reviewed in the relationships between performance and age, and the effects of training on performance. A model is then proposed…

The aim of this study was to investigate the strategies leading to test item responses in 60 young (20-25 years) and 60 middle-aged (35-40 years) adults, whose highest level of education had been either secondary, technical or university. Subjects were individually administered a 12 item test similar to Raven's Progressive Matrices, and were…

Leading educational psychologists address problems in adult development and learning in this book. "What Does Educational Psychology Know about Adult Learning and Development?" (M. Cecil Smith, Thomas Pourchot) is the introduction. "We Learn, Therefore We Develop" (Nira Granott) tackles the problem of distinguishing between…

This book, which incorporates information gathered through research in the United Kingdom and the United States, explores the nature and importance of learning throughout the human life cycle. The following are among the topics examined: (1) learning and third age education (the emergence of education for adults, third age education); (2) learning…
