S. Sulzbacher et al., CROSSED DOMINANCE AND ITS RELATIONSHIP TO INTELLIGENCE AND ACADEMIC-ACHIEVEMENT, Developmental neuropsychology, 10(4), 1994, pp. 473-479
Measures of handedness have long been utilized as part of the neuropsy
chological assessment due to evidence that hand preference is related
to cerebral dominance for language. Many lateral dominance examination
s also include measurement of eye, ear, and/or foot preference, presum
ably for assessment of crossed laterality. Although a reliable relatio
nship between crossed laterality and intelligence or achievement has n
ot been demonstrated, the assumption that crossed eye/foot or eye/hand
dominance predicts poor intelligence or achievement persists. In the
present study, a group of 93 normal children between the ages of 2 and
8 years old were followed longitudinally. No relationship was found b
etween crossed laterality and intelligence or achievement.
