Research supported by U.S. Public Health Grant No. 293-60 to D.O. Hebb and Grant No. 298-3980 of the Medical Research Council of Canada to Virginia I. Douglas. Part of a PhD thesis submitted to McGill University (Friebergs, 1965).

The first major section of this report describes in detail an information-integration theory which seeks to explain how an organism selects information and integrates it with other information from the environment and from the organism's internal processes. The model treats information as a pattern of neural activity composed of a plethora of unit…

Concludes that skilled adult readers may use the meanings of words ahead of fixation to enrich their interpretation of a text or use those words more simply as markers to guide further eye movements to the location of the next useful fixation. (FL)

Reviews findings of recent television research and discusses two dominant issues: the nature and determinants of children's attention to television, and the amount and kind of content retained by different age groups. It is recommended that research on media effects incorporate age-related and individual difference factors. Nineteen references are…

Attention acts as the mind's "gatekeeper" by regulating and prioritizing the stimuli processed by the central nervous system. It is essential for cognitive performance, memory, and behavior, and we know that even slight deficiencies in attention compromise learning. Basic neuroscience research further indicates that attention consists of (fairly)…

Thirty grade 4 subjects were individually tested on a digit span test of working memory capacity (Case and Kurland) and the Reading Span Test (Daneman and Carpenter). The Reading Span Test was administered using sentences at a grade 2, grade 4, and grade 6 reading level. It was predicted that, as the decoding demands of the stimulus sentences in…

Two studies are described which were conducted at the University of Kansas Center for Research on the Influence of Television on Children to evaluate the effects of form and content independently on the social behavior of young children. In both studies, preschool children were observed during an unstructured play session in a laboratory room…

This study replicated Daneman and Carpenter's finding that the reading span test, as a measure of working memory storage and process functions, is predictive of performance on standard reading comprehension tests. It showed that reading span is related to the ability to draw inferences from, integrate, and encode text information. (Author/PN)

Concludes that children could attend to texts selectively when reading or listening to expository prose, and when reading, but not in listening to narrative prose. (FL)

This study examined the utility of the Planning, Attention, Simultaneous, Successive (PASS) theory of intelligence as measured by the "Cognitive Assessment System" (CAS) for evaluation of children with attention-deficit/hyperactivity disorder (ADHD). The CAS scores of 51 Dutch children without ADHD were compared to the scores of a group…

Until recently it has been possible only to measure the behavioral products of cognitive processing, e.g. reaction time. However, this is a rather indirect way of studying brain substrates of cognition. Psychophysiological techniques can be used to study the neural mechanisms of cognition. In this experiment brain electrical activity was measured…

A conceptual framework of attention can be organized around three functions of attention: determining how much capacity is to be deployed (attention allocation), for how long (attention maintenance), and to which potential information sources (attention direction). Within this framework, several critical distinctions can be made between processes…

This article explores evidence related to the idea that children with language impairments present co-occurring limitations in data-driven and conceptually driven processing. It concludes that together, these limitations contribute to a heightened sensitivity to increasing task demands in children with language impairments. Assessment and…
