The divergent predictions of 2 models of dual-task performance are investigated. The central bottleneck and central capacity sharing models argue that a central stage of information processing is capacity limited, whereas stages before and after are capacity free. The models disagree about the nature of this central capacity limitation. The…

The model of a single central bottleneck for human information processing is critically examined. Most evidence cited in support of the model has been observed within the overlapping tasks paradigm. It is shown here that most findings obtained within that paradigm and that were used to support the model are also consistent with a simple resource…

The computational model of question answering proposed by a computer program, QUALM, is a theory of conceptual information processing based on models of human memory organization. It has been developed from the perspective of natural language processing in conjunction with story understanding systems. The processes in QUALM are divided into four…

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…

Three outlines prepared by an ERIC Clearinghouse to assist in the classification of subject matter in the field of educational facilities. The first outline contains elements of the educational environment which are related to facilities. The second is concerned with the design, development and administration of those facilities. The third section…

The model as currently developed consists of three major aspects: contexting, operation, and memory. The contexting aspects of the model are concerned with the higher level cognitive behavior associated with selection of appropriate behavior, maintenance of goals-directedness, and evaluation of completed behaviors. The operational aspects of the…

Thirty-two students at the University of Oregon were tested to determine the effects of media on mental imagery and memory. The model incorporates a dual coding hypothesis, and five single and multiple channel treatments were used. (Author/JEG)

Suggests that the information processing model of writing developed by cognitive psychologists provides a construct for researchers to work with but has little to contribute to classroom pedagogy. (MM)

Looks at an alternative method to linear notes for organizing thoughts when preparing a talk or paper. This method displays the manner in which the relationships of a subject are organized and offers a format for displaying complex inter-dependencies in place of linear notes. (Author/MER)

Considers several recent information-processing models of sentence-picture matching to assess their implications for sentence processing. (Editor/RK)

The technique for examining the time course of information processing developed by D. E. Meyer et. al. (1988) is analyzed. Research is provided, which suggests that this new method gives important qualitative support to some stochastic models and quantitative support to the continuous diffusion model of information processing. (SLD)

Presents new methods for compressing bit matrices in large information retrieval systems which exploit possible correlations between rows of words and columns of documents. Three encoding methods are tested and compared--Shannon-Fano, arithmetic, and Huffman--and an appendix discusses binomial coefficients. (20 references) (LRW)

Reading is a process that bridges the distinction between perceptual and cognitive processes but the formalisms of the information processing approach to the study of reading apply most naturally either to models assuming a series of noninteracting stages of information processing or to a set of independent parallel processing units. This paper…
