title: Handedness and spatial ability in children: further support for Geschwind's hypothesis of "pathology of superiority" and for Annett's theory of intelligence.
abstract: Spatial ability of 60 left-handed and 60 right-handed school children was investigated using a battery of nine tasks. The results do not agree with Levy's (1969, 1976) theory predicting spatial inferiority of left-handed individuals. Instead, higher performance by left-handed children provided further support for Annett's (Annett & Manning, 1989) theory on intelligence and for Geschwind's (Geschwind & Galaburda, 1985) hypothesis of "pathology of superiority." The distinction of left-handed and right-handed individuals into familial and nonfamilial groups appeared to be psychologically equivocal according to our results.
