Attempts to validate the basic constructs of a theory of cognitive switching developed from human performance literature and signaled stopping research. Presents data which display behavioral traces of the ways people organize television news into their information-processing system. (JMF)

Discusses the scope of information science, problems involved, and the areas of research needed for development. In particular, the processes occurring in thinking, memory, and knowledge are considered as they arise in the production and receipt of information. (Author/RAA)

In a task designed to separate perceptual processes from memory, reading-disabled 12-year-olds showed no perceptual deficits as compared to their peers. However, they exhibited major deficiencies in memory skills, appearing to suffer from a basic information-processing deficiency. (Author/CS)

Discusses the Peirce On-line Resource Testbed (PORT), a digital archive of primary data. Highlights include knowledge processing testbeds for digital resource development; Peirce's pragmatism in operation; PORT and knowledge processing; obstacles to archive access; and PORT as a paradigm for critical control in knowledge processing. (AEF)

Discusses computational studies of learning in artificial neural networks and findings that may provide insights into the learning abilities of the human brain. Describes efforts to test theories about brain information processing, using artificial neural networks. Vignettes include information concerning how a neural network represents…

Asks whether theories of knowledge representation provide a basis for the development of theories of knowledge structuring in instruction. Discusses codes of knowledge, surface versus deep structures, semantic networks, and multiple memory systems. Reviews research on teaching, external representation of cognitive structures, hierarchical…

This article examines the principles of information processing and the ways in which they can both facilitate and interfere with the language comprehension and production performance of children with language impairment. The clinical implications of these notions for assessment and intervention with children are discussed. (Author/CR)

Examined changes from age 7 to 82 years in processes responsible for preparation and interference control underlying alternation between two tasks. Found a U-shaped function for switch costs, with larger costs for young children and older adults. Age-related variance in task-switching performance was partially independent from age-related variance…

Objective: To evaluate the effectiveness of a social cognitive intervention program for Dutch aggressive boys and to compare it with a social skills training and a waitlist control group. Method: A randomized, controlled treatment outcome study with 97 aggressive boys (aged 9-13 years) was presented. An 11 session group treatment, a social…

Event-related potential (ERP) studies have shown that emotional stimuli elicit greater amplitude late positive-polarity potentials (LPPs) than neutral stimuli. This effect has been attributed to arousal, but emotional stimuli are also more semantically coherent than uncategorized neutral stimuli. ERPs were recorded during encoding of positive,…

Interest regarding neural information processing in autism is growing because atypical perceptual abilities are a characteristic feature of persons with autism. Central to our review is how characteristic perceptual abilities, referred to as "perceptual signatures," can be used to suggest a neural etiology that is specific to autism. We review…

This research considers how distinct news frames work in combination to influence information processing. It extends framing research grounded in prospect theory (Tversky & Kahneman, 1981) and attribution theory (Iyengar, 1991) to study conditional framing effects on associative memory. Using a 2 x 3 experimental design embedded within a…

The purpose of this article is to review and critique each of the research studies published in this special issue. We will critique each article, derive one or more instructional design heuristics based on the findings for each study, and provide recommendations for extending particular lines of research. Three suggestions are provided concerning…

The most salient characteristic of the psychopath is the propensity to engage in maladaptive and inappropriate behavior of all sorts, including antisocial and criminal actions. Consequently, there is considerable interest--particularly in the field of criminology--in determining what sorts of treatment interventions are likely to be effective in…
