Repetition is a central phenomenon of behavior, and researchers have made extensive use of it to illuminate psychological functioning. In the language sciences, a ubiquitous form of such repetition is "structural priming," a tendency to repeat or better process a current sentence because of its structural similarity to a previously experienced…

At some time during every fixation a decision is made to move the eyes, directing them to a new location in the stimulus array. To understand the eye movement control processes, three general hypotheses concerning the cognitive basis for deciding to move the eyes were investigated: the saccade (movement) initiation time is determined only on the…

Connectionist (parallel distributed processing) modeling provides a new way to approach the neurological study of language. This method focuses on the interplay between a computational model and the appropriate neurological, neuropsychological, and speech and language data, couched in connectionist mechanisms that map naturally to what is known of…

Discusses prevailing ideas of how children learn language and addresses the argument of rules versus analogies in learning to form the past tense of verbs. Cites cases involving connectionist models. (ML)

G. Wolford's perturbation model of letter identification is designed to account for identification errors of briefly presented characters. Its chief assumptions are that features are extracted in parallel, that some of these features become perturbed or mislocalized, and that mislocalizations are more likely to occur in the direction of the fovea…

This article reviews the work on patients who have undergone partial or complete brain bisection and addresses the concept of modularity from three different perspectives: (1) structure-function correlations; (2) modular components of cognitive processes; and (3) integration of modular processes. Several brain pictures and diagrams are presented.…

This study found that 30 children with reading disability (RD) performed more poorly than 30 children with normal reading achievement on tasks of serial rapid naming, verbal fluency, letter-based word retrieval, and articulatory speed. RD children had significantly longer reaction times and production durations on the serial naming task. Findings…

Two divergent views of linguistic ability in adulthood currently exist. One view maintains that verbal ability is preserved in old age, while the other view maintains that verbal ability declines, especially comprehension. To analyze the effects of semantic priming during sentence processing by 30 younger adults (mean age, 25 years) and 30 older…

Reviews cases which support the view that parts of the left hemisphere control languages, no matter how it is expressed, while right-side regions are involved only in skilled nonlinguistic movements and perceptions. Compares recent findings with previously held theories. (ML)

Presents results of an experiment seeking relationships between motor activities and more central language production processes. Concludes that the same motor program was used for occurrences of repeated morphemes in the experiment. Reports that nonrepeated morphemes were recovered from verbal memory while the preceding repeated morpheme was being…

The product of researchers' efforts to develop a computer processor which distinguishes between relevant and irrelevant information in the database, Spreading Activation Processor for Information Encoded in Network Structures (SAPIENS) exhibits (1) context sensitivity, (2) efficiency, (3) decreasing activation over time, (4) summation of…

This essay, the concluding section of a larger study, examines the present state of cognitive science and instructional theory as reflected in the study's earlier chapters. Cognitive analyses of tasks are reported in the broad domain of language comprehension and production (e.g., understanding, composing, and answering questions about texts). The…

Reviews the research on how readers or listeners construct mental models of the situation a writer or speaker is describing. Narrative components and spatial models are discussed. (YP)

A developmental study investigated the pictorial and linguistic main idea identification skills of 104 students in second, fifth, and eighth grades. In the pictorial task, the subjects studied a complete picture story and ranked the effectiveness of four separate main idea alternatives at capturing the meaning of the story. Following the same…

Readers as well as writers compose meaning. Using the same characteristics essential to effective writing--planning, drafting, aligning, revising, and monitoring--readers react creatively with the text. In response to the author's intention and their own knowledge base, they decide what they want to get from their reading. Constantly renegotiating…
