Executive function (EF) is a term used to describe the processes responsible for purposeful, goal-directed behavior and has been described as the "air traffic controller" or "CEO" of the brain. EFs are an important factor in overall quality of life, including school and job success. EFs are measured predominately through two…

The background to this study are the difficulties facing the majority of Greek pupils in understanding chemistry concepts and, therefore, performing well in the National Examinations. The aim was to explore the problems and to suggest ways in which the situation might be improved. Working with 105 Greek pupils aged 15 to 16, the first stage of the…

The literature reveals a marked decline in performance on the Visual Reproduction subtest with increasing age. Both level of education and intelligence seemed to exert a substantial influence on performance which may be significant in clinical evaluations. (Author)

The relation of domain knowledge to achievement, and changes in this relation that occur with age and type of memory task, are discussed. First, different mechanisms through which domain-specific knowledge relates to strategy use in memory tasks are summarized. Then, empirical evidence that indicates direct effects of the knowledge base on memory…

This study examined the effects of socio-economic status (SES) and categories of learning when holding ethnicity constant. Seventy-two subjects were randomly selected from two socioeconomic levels; 36 each from middle and low socioeconomic status. Fourth and fifth grade children were used. Three hypotheses were tested: (1) positive correlations…

A new regression-based logic strategy is presented for comparing cognitive profiles of children developing reading skills at different rates. Results with 907 children support the phonological-core variable-difference model of reading disability, with the degree of aptitude-achievement discrepancy unrelated to unique cognitive trade-offs of…

Assessed the relative availability of Piagetian formal reasoning concepts at different ages in adulthood and examined performance patterns on standardized intelligence tests, logical reasoning, immediate memory span, and personality measures. Results indicated that although the elderly students' performances were generally adequate, their scores…

Discusses a study that examined the role of four cognitive factors (formal reasoning ability, prior knowledge, field dependence/independence, and memory capacity) on achievement in chemistry as measured by tests of lab application, chemical calculations, and content knowledge. Reports the significance of prior knowledge and formal reasoning…

The relationships between classroom performance and five possible predictor variables were studied. The ways in which these variables relate to performance in a classroom learning situation were examined, with the hypothesis that attributional style and motivation would be the best predictors of classroom performance. The variables were: (1)…
