title: Cognitive and nonverbal perceptual processing in dyslexics.
abstract: A sample of 33 dyslexic and 33 control children were compared on tasks involving visual matching with spatial transformation (VMST), tactual serial matching (TSM), visual sequential memory (VSM), and auditory sequential memory (ASM). Contrary to expectation, the dyslexics performed at the same level as controls on VMST. This result was not explicable as a floor or ceiling effect and was considered evidence that dyslexics do not suffer impairment in visual spatial transformation ability per se. Dyslexics were not significantly different on TSM, but were inferior to controls on VSM and ASM.
