This study examined differences in performance on a visual-search task between dysphonetic dyslexic children and three other groups of youngsters (other dyslexic, brain-damaged, and normals) on measures of cerebral dysfunction and cerebral organization. Subjects were required to match a centrally located design to an identical image, yielding a measure of cerebral dysfunction, i.e., latency. Cerebral organization of the diagnostic groups was studied by measuring the conjugate lateral eye movements of each child. Prior research suggests that initial direction of lateral eye movement on a cognitive task is indicative of lateralized cerebral activation. Analysis indicated that the dysphonetic dyslexics group, as predicted, differed significantly on latency from the normal and brain-damaged groups but not from the other dyslexic group. The dysphonetic dyslexic group differed significantly from all other groups on the measure of cerebral organization.
