In this study, we examined to what extent orthographic skills, phonological processing, oral vocabulary, and word memory accounted for variance in reading comprehension among upper-elementary school children with and without dyslexia. The tasks came from the Tests of Dyslexia (TOD). Data from 753 participants (typically developing n = 575;…

Speech, reading, and writing are the basic forms of linguistic communication. Therefore, it is very important to diagnose any problems with them as early and completely as possible, particularly in children with special needs. One of the methods that focuses primarily on the diagnosis and therapy of such learning difficulties is the one developed…

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…

Cognition-related brain responses to meaningful and meaningless figures were registered in 5-year-old kindergarten children who either had been subtyped as being at-risk of developing an L- or P-type dyslexia (LAL versus LAP) or who were not at-risk. While identifying, naming, or categorizing pictures, event-related potentials (ERP) were…

It is suggested that reading is not a unitary process, but the acquisition of a succession of skills. Different retarded readers may break down at different stages in the acquisition of these. Each disability type may be associated with a particular type of deficiency in conceptual thinking. (Author/SJL)

Elementary and middle school children (n=105) completed measures of reading achievement and cognitive abilities. Factor analysis produced three empirically and theoretically derived factors, auditory processing, visual processing/speed, and memory. Together the three factors combined predicted 61 to 85% of the variance associated with different…

The rationale and development of a new series of motion picture tests of perceptual abilities of young children are described, and preliminary data regarding their reliability and validity are presented. The data suggests that the film tests are promising new perceptual measurement instruments. (MS)
