A model of relationships among the cognitive components of working memory, representation, metacognition, and performance implicated in the acquisition and transfer of the LOGO computer language was developed and tested with 48 second graders. The respective contributions of each component vary with the transfer task. (SLD)

Models of working memory were compared in 2 experiments as means of explaining variance in the comprehension of 95 skilled and 80 learning-disabled readers from grades 4 through 7. Results suggest that learning-disabled children's working memory problems are functionally related to higher order processes and not memory alone. (SLD)

Reviews research on the nature of attention and memory and proposes a model of the relationship between them during second-language acquisition complementary to Schmidt's noticing hypothesis and oppositional to Krashen's dual-system hypothesis. The article maintains that differential performance on implicit and explicit learning and memory…

The present study investigated the working memory abilities of children with attention deficit/hyperactivity disorder (ADHD) as measured by the Stanford-Binet Intelligence Scales, Fifth Edition (SBV). In a retrospective causal-comparative design, the archival data of 46 ADHD children were compared to 59 nondiagnosed children. The ADHD children…

This study indicates that the way in which stories are presented to children (verbal versus pictorial) makes little or no difference in the children's comprehension or recall of the stories. Ninety-six kindergarten and second grade children either looked at a series of pictures (and were told they formed a story) or listened to the story through a…

The study of ability factors in young children has passed the stage of demonstrating that separate factors exist, the effort now being devoted to systematic identification of measurable abilities. This study was designed to confirm some of the tentative abilities demonstrated in other studies and to extend the exploration into memory processes and…

This book synthesizes information from a range of scientific disciplines, including neuroscience, developmental psychology, and psychiatry, to explore the idea that the mind emerges at the interface of interpersonal experience and the structure and function of the brain. Each chapter explores a major domain of human experience. Following an…

Orthogonally manipulated three word characteristics in Dutch and English--word imageability; word frequency; and cognate status--and obtained similar data patterns for three groups of bilinguals different from one another in second-language fluency. Findings indicate that "concept mediation" is a universal process in translating words…

Discusses content learning versus process learning, describes process learning with computer-based simulations, and highlights an empirical study on the effects of process learning with problem-oriented, computer-managed simulations in technical vocational education classes in West Germany. Process learning within a model of the cognitive system…

Reviews studies on the representation of words and their meanings in bilingual memory. The roles of the following variables in bilingual memory organization are discussed: the level of proficiency in the second language (L2), the strategy of learning the L2, the interval between previous and current use of L2, and the L2 learning environment. (43…

In 2 experiments, the authors tested whether the classical modality effect--that is, the stronger recency effect for auditory items relative to visual items--can be extended to the spatial domain. An order reconstruction task was undertaken with four types of material: visual-spatial, auditory-spatial, visual-verbal, and auditory-verbal.…

We examined underlying mechanisms for comprehension differences across expository and narrative text while controlling for factors confounded in the extant literature. Fourth grade students (n=32) read both an expository and a narrative text, and completed both a local comprehension assessment, and a global retelling assessment for each text.…

Purpose: This study examined the cognitive demands of 2 selection techniques in augmentative and alternative communication (AAC), direct selection, and visual linear scanning, by determining the memory retrieval abilities of typically developing children when presented with fixed communication displays. Method: One hundred twenty typical children…

In this paper the theory that human thinking proceeds according to the computer model, or symbol manipulation, is reviewed and challenged. The research used as subjects five highly rated tournament chess players who "thought aloud" during a chess game to provide tape recorded protocols of decisions made while playing. These protocols…

Limitations of the retrieval strategy dimension of Siegler's (1982, 1984) distributions-of-associations model of young children's estimation of sums are delineated, an alternative model is described, and findings of two studies designed to test key assumptions of the models are reported. In Study 1, kindergarten children with normal IQ and no…
