To the best of our knowledge, the genetic foundations that guide human brain development have not changed fundamentally during the past 50,000 years. However, because of their cognitive potential, humans have changed the world tremendously in the past centuries. They have invented technical devices, institutions that regulate cooperation and…

Students' thinking about the relation between effort and ability can influence their motivation, affect, and academic achievement. Students sometimes think of effort as inversely related to ability (such that people with low ability must work harder than people with high ability) and other times think of effort as positively related to ability…

Developmental contextualism focuses on changes in fused relations between developing people and their changing contexts. Research on cognitive training in the aged years provides evidence about plasticity throughout life because it alters developmental trajectories through revised person-context relations. The studies in the current issue support…

Ten possible sources of individual and developmental differences in memory span--rehearsal, grouping, chunking, retrieval strategies, item identification, item ordering, capacity, susceptibility to interference, search rate, and output buffer--were examined in a review of the literature. Speed with which presented items can be identified emerged…

Reviews literature on hemispheric specialization. Argues that foundations of hemispheric specialization are present very early in life and that children's greater ability to recover functions following brain injury suggests developmental changes in brain organization. (CMG)

Discusses metacognitive and associative models of children's strategy discovery and use. Contends that models based on only one type of mechanism cannot entirely account for observed variability and constraint revealed by microgenetic studies of children's strategy change. Proposes a new model of children's strategy development in which…

Because developmental theories of Vygotsky, Piaget, and Bandura are far more complex than much of the empirical work based on them, researchers have concentrated on relatively narrow aspects of each man's ideas, in the process magnifying the differences between them. Nevertheless, basic differences do exist in each theorist's conceptualization of…

Notes that moral decisions include both moral concepts and factual beliefs. Considers possible sources of variation in factual beliefs and presents research into children's and adults' thinking about practices based on factual beliefs different from their own. Discusses how individuals take these differences into account when judging the seemingly…

Lev Vygotsky maintained that historical and cultural aspects of development started from the point at which humans could first be distinguished from apes. It is critical to consider the dialectical relationship between the individual and the cultural environment in which the child actively masters cultural behavior. Interaction with others…

If human cognitive development advances through a series of broad and general stages, then the child's mind at any developmental point should seem consistent and similar across situations in its maturity level and general style. However, there appear to be factors and conditions that promote homogeneity and heterogeneity in the child's cognitive…

In response to Leonard (EC 600 867), two aspects of language development are identified in which the discrepancies between domains of language and/or cognitive development often observed in specific language impairment children occur naturally as a consequence of individual variation in rate of development together with relative independence of…

Presents a brief overview of research and developments in the study of formal operations thought since 1972 along with some speculations concerning future research directions. (Author/MP)

Initial research on maternal reminiscing style established clear and consistent individual differences that vary along a dimension of maternal elaboration and that are related to children's developing autobiographical skills. More recent research has linked maternal elaborative reminiscing to strategic memory development, language and literacy…

To foster individual development, educators must seek the gifts in every child, in those not demonstrating academic abilities as well as in the most brilliant. Instead of stifling thinking, creativity, and interest development, educators must encourage these behaviors. Currently, a big discrepancy exists between the child's potential and what…

Mental abilities can be analyzed at four levels: composite tasks, subtasks, components, and metacomponents. Each level of analysis reveals something about the structure and content of mental abilities responsible for intelligent performance. (Author/WI)
