The number of children and adolescents accessing the Internet as well as the amount of time online are steadily increasing. The most common online activities include playing video games, navigating web sites, and communicating via chat rooms, email, and instant messaging. A theoretical framework for understanding the effects of Internet use on…

It is argued that an area of linguistic research ripe for exploration is how the speaker actually makes use of linguistic knowledge in the production or reception of utterances. It is proposed that speech production is a lexically driven rather than semantically driven process and that the speaker's procedural competence is lexico-syntactic in…

Paivio's Dual Coding Theory has received widespread recognition for its connection between visual and aural channels of internal information processing. The use of only two channels, however, cannot satisfactorily explain the effects witnessed every day. This paper presents a study suggesting the presence a third, kinesthetic channel, currently…

This paper discusses a model of information storage and retrieval, the k-d tree (Bentley, 1975), a binary, hierarchical tree with multiple associate terms, which has been explored in computer research, and it is suggested that this model could be useful for describing human cognition. Included are two models of human long-term memory--networks and…

Soviet neuropsychologist Sokolov's notions of tonic and phasic orienting responses and of defense responses are examined for relevance to individual information processing. The phasic orienting response provides an index to attention and to information demands generated by the cerebral cortex. The sum of orienting responses elicted by a message…

An experimental context designed to directly affect discourse processing by inducing subjects to generate inferences involving text content was compared to a context in which subjects simply listened to and recalled the content of a text. Context did effect the amount of inferred and overgeneralized semantic information in subjects' text recalls.…

This research furthers our understanding of the relationship between an organismic factor, "cognitive style," and performance on concept learning and information processing tasks. These results, obtained from students in grades six, eight, and 10, indicate that not only do "high analytical" type students perform better on this…

A framework for viewing human text comprehension, memory, and recall is presented that assumes patterns of abstract conceptual relations are used to guide processing. These patterns consist of clusters of knowledge that encode prototypical co-occurrences of situations and events in narrative texts. The patterns are assumed to be a part of a…

In contrast to conventional information storage and retrieval systems in which a body of knowledge is thought of as an indexed codex of documents to which access is obtained by an appropriately indexed query, this interdisciplinary study aims at an understanding of what is "knowledge" as distinct from a "data file," how this knowledge is acquired,…

An experimental study of the efficiency of human information processing is based on the Bayesian model for simple hypothesis testing with fixed binomial sampling. Each of 60 subjects is analyzed with separate ANOVAs focusing on two efficiency variables. Sample size and critical value are also analyzed. Subjects show very different utilization of…

Explains that the concept of message discrimination was originally developed as a means of determining actual units of content that individuals extract from encounters with mass media and describes the relationship between message discrimination and the two related concepts of systematic information availability and knowledge.

The aim of this paper is to attempt to develop a neuropsychological theory of attention which is compatible with contemporary theories of human information processing. (Author/RK)
