We studied developmental trends in 5 important reasoning tasks that are critical components of the operational definition of rational thinking. The tasks measured denominator neglect, belief bias, base rate sensitivity, resistance to framing, and the tendency toward otherside thinking. In addition to age, we examined 2 other individual difference…

There are two major hypotheses concerning the developmental trends of processing speeds. These hypotheses explore both local and global trends. The study presented here investigates the effects of people's different knowledge on the speed with which they are able to process information. The participants in this study are gifted children aged 9,…

The expansion of digital technologies and the rapid changes they undergo through time face users with new cognitive, social, and ergonomic challenges that they need to master in order to perform effectively. In recent years, following empirical reports on performance differences between different age-groups, there is a debate in the research…

Research on children's concepts of intelligence has not considered how children conceptualise specific thinking skills. This study extends previous research on the development of children's concepts of intelligence and produces novel data on children's understandings of effective thinking and thinking skills. Seventy-five children were sampled…

Reviews developmental literature on cognitive gender differences; and compares past and present trends in gender differences, by age, from standardizations of the Wechsler Intelligence Scales and the California Achievement Tests. Decreases are found in gender differences for adolescents but not for adults. Implications are discussed. (SLD)

Recent investigations have demonstrated greater variance in change in intellectual performance between different generations or age groups than is true for generalized developmental change across chronological age. Such findings have led to a careful investigation of certain environmental factors which might account for such change. A new…

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…
