The authors examined the processing of phonological and orthographic word representations among 17 dyslexic and 16 normal college-level readers using Event-Related Potential measures. They focused on 2 early components--the P200 and the P300. The results revealed P200 and P300 components of lower amplitude and later latency among dyslexic readers…

Deals with the problem of transcoding, that is, when in switching from one sign system to another relations must be created between corresponding structures in the different systems. The mechanisms of transcoding are examined for spoken and written speech, numeral words and figures, and tone symbols and musical notes. (SCC)

Work with patients with attentional deficits produced by posterior cerebral lesions has shown that such patients can identify words correctly even when they fail to report letters in nonwords contralateral to the lesion. Because of this, it has been assumed in cognitive neuropsychology that lesions do not produce new phenomena but instead provide…

The conference papers in this collection emphasize the theoretical significance of their authors' work in the areas of mathematical and cognitive psychology. Major topics considered include facilitation of problem solving; psychological differences among problem isomorphs; the process of understanding in problem solving; processing information for…

Describes an experiment measuring response latency which required subjects to make a word-nonword decision in response to a visually presented item. (AM)

This paper is a summary of research on the perceptual and memory processes related to reading, their developmental progress in children, and the reading abilities in adults. Reported among the results of the various studies are the following: (1) developmental changes in reading after second grade primarily improve speed of coding, (2) reading…

In order to determine whether there are developmental differences in the handling of the modality attribute 32 children from each of grades two and six and 32 college students were presented with a video-taped mixed-modality list of 32 first grade words. Subjects were asked to recall the words, to identify the presentation modality of each word on…

The central question of this report concerned the role of formal similarity in free recall of lists of trigrams and lists of three-letter word triads. Similarity was manipulated among trigrams by duplicating words. An initial study showed that lists of 16 letters were learned more rapidly than a list of 16 three-letter words. Therefore, in the…

The relationship between the effects of morphological complexity and associative production frequency was investigated in two experiments on sentence verification. The purpose of the study was to investigate how morphologically derived words are represented in memory. (Author/RM)

Two experiments, a shadowing task and a mispronunciation-detection task, were performed to investigate the interactions between the data-driven primary speech perception process and the knowledge-driven word recognition process in the comprehension of continuous speech. Results are applied to an active direct access model of word recognition.…

Given the currently numerous applications of word-nonword classification tasks in psychological research, the present study was designed to determine the relative influences of a large number of potentially important variables on response time in tasks of this sort. (Author/NCR)

The probability of recognizing a member of a word pair tested with the pair intact was shown to equal the probability of recognizing a single word plus the probability of recalling an unrecognized word. (Author/NCR)

Explores the recognition and memory of words by hearing and deaf children and finds evidence relevant to the reading difficulty experienced by the deaf. (FL)
