Examines the development of grapheme-phoneme conversion ability in normal and reading-age matched dyslexic readers. Thirty-six normal readers (mean age 9.5 years) and 18 children diagnosed dyslexic (mean age 12.1 years) served as subjects. (MP)

Two experiments examined developmental changes in reasoning about intensive quantities--predicting mixture intensity of pairs of liquids with different intensities of red color. Results showed that cognitive averaging in this domain developed late and slowly. Predominating up to 12 years was an extensivity bias, a strong tendency to use rules that…

The current work examined age differences in the classification of novel object images that vary in continuous dimensions of structural shape. The structural dimensions employed are two that share a privileged status in the visual analysis and representation of objects: the shape of discrete prominent parts and the attachment positions of those…

A study consisting of two experiments attempted to further adapt the visual preference procedure for determining children's meaningful phonological perception. In the first experiment, 1-year-olds were presented with auditory stimuli (words) and screens containing paired color photographs of the object described by each word and of an unusual…

THE AMERICAN OPTICAL (AO) COMPANY'S SIGHT SCREENER, A PORTABLE BINOCULAR INSTRUMENT DESIGNED FOR MASS VISION TESTING, WAS EVALUATED AT THE UNIVERSITY OF MARYLAND READING AND STUDY SKILLS LABORATORY TO DETERMINE ITS CAPACITY TO IDENTIFY STUDENTS NEEDING PROFESSIONAL EYE EXAMINATIONS PRIOR TO READING INSTRUCTION. DATA FROM 106 PROBATIONARY FRESHMEN,…

THIS PROJECT ANALYZED A LONGITUDINAL READING PROGRAM FOR IDENTIFICATION OF GROWTH IN ABILITIES, AND THE RELATIONSHIP BETWEEN TESTS. APPROXIMATELY 60 PUPILS FROM CONTROL AND EXPERIMENTAL CLASSES RECEIVED INTENSIVE READINESS TRAINING IN VISUAL PERCEPTION, AUDITORY DISCRIMINATION, AND LANGUAGE SKILLS. ALL WERE TESTED AT 25-MONTH INTERVALS. ANALYSES…

Using Kleinfeld's review of Inuit possible cognitive strengths as framework, reviews 28 studies published since 1973 on cognition (broadly defined to include studies of visual/social perception, cognitive style, concrete/formal operational ability, language abilities, cognitive strengths) among Native North Americans. Identifies weaknesses of…

Results reaffirm the notion that retarded individuals are less adept at recognizing familiar forms haptically than visually. (Author)

Adults' ability to track a moving target was examined in two experiments in order to compare their performance with that of very young infants. Results indicated that (1) adults'"overshoot" errors resembled those reported for young infants; and (2) adults had problems tracking a moving target which unexpectedly changed direction. (Author/DB)

Presents a review of the literature dealing with the theory of the naming of colors. A comparison is made between the names of colors in Italian and Dutch, discussing the differences between languages in terms of the influence of the sociocultural context. (61 references) (CFM)

The relation between perceptual organization and categorization processes in 3- and 4-month-olds was explored. The question was whether an invariant part abstracted during category learning could interfere with Gestalt organizational processes. A 2003 study by Quinn and Schyns had reported that an initial category familiarization experience in…

Lip movements were examined across several repetitive speaking conditions (speech alone and speaking concurrently with a linguistic, cognitive, or visuomotor challenge task) in 20 young adults. Performance in these nonspeech activities was also compared between isolated tasks and concurrent speech conditions. Linguistic challenges resulted in…

The vast majority of work on the processing characteristics of poor readers has been conducted with readers of English. In this article we report on results that outline the processing characteristics of poor readers of the Korean alphabetic-syllabic script, "Hangul." Three groups of readers (10 good readers, 10 poor readers and 9 poor readers…

This study attempts to investigate the role of sensorimotor impairments in the reading disability that characterizes dyslexia. Twenty-three children with dyslexia were compared to 22 control children, matched for age and non-verbal intelligence, on tasks assessing literacy as well as phonological, visual, auditory and motor abilities. The dyslexic…
