Tag clouds generated in social tagging systems can capture the collective knowledge of communities. Using as a basis spreading activation theories, information foraging theory, and the co-evolution model of cognitive and social systems, we present here a model for an "extended information scent," which proposes that both collective and individual…

A MODEL FOR THE ANALYSIS OF SPELLING BEHAVIOR WAS PRESENTED AND DESCRIBED AS REPRESENTING TOTAL SPELLING BEHAVIOR AS A FORM OF INFORMATION PROCESSING SYSTEM. THE MODEL REPRESENTS THE PROCESSING OF A NEED TO CORRECTLY SPELL A WORD THROUGH THE SEQUENCES OF VARIOUS PROCESSING CHANNELS TO THE WRITING OF THE WORD AND FEEDBACK FOR CORRECTION WHEN…

Presentation and criticism of pertinent work, plus the authors' own model. (Text is in French.) (DB)

Contends that redundancy increases information transmission and reception by (1) decreasing equivocation and error and (2) establishing memory traces and inhibiting forgetting. (PD)

Defines a "communicate"--the objectification of a subject's internal model of the object of reality by means of a certain set of physical signs--and examines its information value with relation to intelligent systems. (CWM)

The ways that children and adults use their limited cognitive processes in comprehending the complex input of a second language are discussed, and an information-processing approach to second-language learning is proposed and supported in a number of areas of second language research. Implications for research and teaching are examined. (MSE)

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…

One of man's most distinctive characteristics is the manner in which he stores and communicates information. Language has always been an important part of this process, but recently machines have begun to share the spotlight. This book presents a look at the role of language in the process of communication and man's relation, present and future,…

Six alternative models of the ways in which individuals accept and organize information from potential sources are proposed. Parameter estimates were obtained from experiments testing the effect of evaluations of performance upon an individual's conception of his own, and others', ability to perform specific tasks. Then the models were tested…

Most research on information utilization in judgment and decision making has followed two basic approaches: "regression" and "Bayesian." Each has characteristic tasks and characteristic information that must be processed to accomplish these tasks. There has been a tendency to work within a single approach with minimal communication between the…

Performance becomes degraded when the human processing system undergoes the stress of processing overload. Information processing models are often used to predict how performance will be affected. Single channel models hypothesize that information will either be lost in the queue or processed with delay. Single capacity models predict that for a…

This study is designed to help provide an understanding of the role semiosis plays in information processes. The object of study is the structure of various types of signs, and a determination of the relationship between sign structure and information properties. A review of the theory of sign structure is followed by an examination of syntactic…

In man-computer communication, the computer responds only as it is programed to respond. A human's response is more complicated because it depends on the "pre-programed" ways that humans process information. The three functions a man performs on received information are conservation (in which messages are retained whole), reduction (in which…

The theoretical and practical structure of a learning skills program based on an organization model is described. The first section of the paper deals with the description and implication of the program. Ideographic questioning and examination of a group of students and their study habits led to the development of an information processing model…
