Previous meta-analyses highlight the role of executive functions (EF), encompassing working memory, task-switching, and inhibition, in reading comprehension, but have not demarcated its role in decoding, defined as use of orthographic patterns to access oral pronunciations. According to the dual-route model, decoding involves parallel activation…

This study aimed to investigate the relationship between different components of active visuospatial working memory and math ability in young children. In a longitudinal study, we compared the contributions of active visual and spatial working memory (WM) tasks in early math performance at two times: the beginning of the first class of primary…

This study explored factors that are associated with calculation development among 176 children at-risk for learning difficulties. Data were collected on working memory, language, non-verbal reasoning, processing speed, decoding, numerical competence, incoming calculation, SES, and gender at the beginning of 1st grade and on calculations over 4…

Three groups of fourth graders who differed on a metamemory pre-test were compared on five working memory tasks to explore the relationship between metamemorial knowledge, total processing space (M-space) and working memory span performance. Children in each group received three versions of each task on concurrent days. It was hypothesized that…

To find predictive relations between measures taken in infancy and later scores on intelligence tests, a study was made that measured in the infant those cognitive processes examined later in life. Operant conditioning tasks were employed which required 3-, 7-, and 11-month-old infants to execute some response to produce an environmental…

Described in the context of a computer simulation are highlights of a program of research focusing on the storage of mathematics problem solving information in young children's memory and the development of such knowledge structures in older children. Specifically discussed are the problem size effect, the network nature of the memory…

This study examined the effect of three aspects of the testing context--physical privacy, anonymity, and offers of help from a tester--on children's expectations. Performance of 96 11-year-old boys and girls on a pictorial recall memory task in a simulated test was evaluated. The subjects were divided into eight different groups varying on the…

Self-report research has inconclusively linked complaints of poor memory functioning, memory performance, and intellectual ability with depression in older adults. In order to investigate more conclusively the correlation between these variables as well as to investigate the effect of age differences, 159 older adults (49 young-old, aged 55-70; 60…

The present study was designed to test how well the measures of the cognitive constructs of M-space, cognitive style, and short-term storage space (STSS) could predict the amount of practice needed to induce successful problem solving behaviors, the ability to transfer behaviors to different contexts, and the readiness to abandon unsuccessful…

A proposal to formulate nomothetic theories -- general statements or scientific laws -- in a way to allow for an immediate test of individual differences is presented. The need for such a proposal is cited in recent developments in structural model building in the area of memory called information processing and in the concern to bring individual…

There is a current trend towards maintaining dementia patients at home and postponing institutionalization as long as possible. Previous research has suggested that frequency of help and support received by the caregiver is more predictive of burden than memory or behavior problems of the patient. Burden and distress were investigated using a…

Many tests which attempt to produce intelligence quotient or mental age scores for children rely on time taken to complete the task for a valid result to be obtained. A number of tests were carried out with both Down's Syndrome and normal children (128 Down's Syndrome; 162 normal) in order to determine (1) relative abilities to complete the tasks…

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)…

Data were gathered, using pre and posttests and interviews, on the learning of individual students during a seven-week unit on a science topic (conservation) in a fourth grade classroom. Case studies of the learning experiences of each child, based on recordings and detailed observations of all class activities, were used to predict student…
