ABSTRACT
Correlations between tests were generally congruent with the laterality scores on the individual tests, but were seldom statistically significant. Data from the dichotic tests were a better indication of language laterality than handedness data. Even better prediction of language lateralization could be obtained when data on both handedness and the dichotic tests were used in a discriminant function analysis: Correct prediction was then achieved in 35 out of 37 cases, including 2 correctly assigned as bilateral. Several visual studies of gender effects use faces as stimuli, for which a right hemisphere advantage would be expected. Most work on the relation between handedness and perceptual lateralization concerns visual and auditory stimuli. In auditory tests of lateralization a variety of the relationships with handedness are reported. Several studies show, as with visual tests, that there is a reduced left hemisphere advantage in left handers.
