Abstract
Two groups of children (30 normal readers and 30 problem readers) were given a series of manual dexterity tasks to establish hand proficiency, and a perceptual task. There was no difference in incidence of handedness vs undifferentiated handedness between the two groups, and this factor was unrelated to the scores on the perceptual task. However, children with reading problems made significantly more perceptual errors than normal readers. The results were discussed in terms of research on laterality and ambilaterality in children with reading problems.
