Investigates word identification in Arabic and basic cognitive processes in reading-disabled (RD) and normal level readers of the same chronological age, and in younger normal readers at the same reading level. Indicates significant deficiencies in morphology, working memory, and syntactic and visual processing, with the most severe deficiencies…

Several experiments involving 150 college students and adults provide evidence for top-down lexical to phonemic activation in auditory word processing. Results indicate that lexical activation can cause the perceptual process to synthesize a highly functional phonemic code. (SLD)

This paper discusses studies of visual dyslexia, the nature of visual processes involved in word recognition, and the contribution of visual memory to word recognition. The paper concludes that, though defects in the physiological aspects of visual processing can lead to reading difficulties, evidence does not indicate the existence of visual…

Three experiments used a visual fixation technique to examine whether toddlers interpret speech continuously. Found that 24-month-olds had delayed responses when a competing distractor picture's label overlapped phonetically with the target at onset, but not when the pictures' labels rhymed, showing that children monitored speech stream…

Judgments of frequency for targets (old items) and foils (similar; dissimilar) steadily increase as the number of times a target is studied increases, but discrimination of targets from similar foils does not steadily improve, a phenomenon termed registration without learning (D. L. Hintzman & T. Curran, 1995; D. L. Hintzman, T. Curran, & B. Oppy,…

Variability in talker identity and speaking rate, commonly referred to as indexical variation, has demonstrable effects on the speed and accuracy of spoken word recognition. The present study examines the time course of indexical specificity effects to evaluate the hypothesis that such effects occur relatively late in the perceptual processing of…

Two aspects of word reading were investigated in two word-naming experiments: the identification of the constituent letters of a word and the processing of letter-order information. Both experiments showed qualitative differences between children with low vision and sighted children, but no quantitative or qualitative differences within the group…

The purpose of this study was to investigate the issue of age-limited learning effects on visual lexical decision in normal and pathological aging, by using words with different frequency trajectories and cumulative frequencies. We selected words that objectively changed in frequency trajectory from an early word count (Thorndike, 1921, 1932;…

Reading comprehension scores from the Wechsler Individual Achievement Tests, the Gates-MacGinitie Reading Test, and the Gray Oral Reading Test were examined in relation to measures of reading, language, and other cognitive skills that have been hypothesized to contribute to comprehension and account for comprehension differences. In a sample of 97…

One hundred forty-four subjects received 4 Brown-Peterson trials with recall triads from a common encoding category. Items on three trials were from a common subset, while on the fourth, the subset was shifted or not, and a cue was presented or not. The cue influenced response generation, a shift improved recall. (CHK)

The object of this investigation was to demonstrate whether or not the predictabilities of the individual letters of words influence recognition of a word. The results indicate that letter predictability influences both accurate word recognition and letter recognition. (DE)

An experiment was carried out to determine how the memory search of a two-clause complex sentence in immediate memory is carried out. An item-recognition task was performed with 32 native English-speaking, right-handed adults who listened to eight two-clause complex sentences presented to the left ear, each immediately followed by a probe word…

Based on a master's thesis (Klorman, 1967) submitted to the University of Wisconsin, and supported by National Institute of Mental Health grant 2 T1 MH-5363-18.

An integrated, three-dimensional cognitive model of reading comprehension was used to investigate the relationship between Piagetian theory (classificational reasoning abilities that emphasize the tacit use of metalinguistic concepts), and reading acquisition (word recognition and reading comprehension). Twenty-four second and third grade remedial…

To develop a coherent description of the knowledge and processes involved in skillful word recognition, a study was devised in which 16 adults participated in four related experiments. The purpose of the first experiment was to examine some basic aspects of the processing of words, pseudowords, and nonwords and to discover basic differences in…
