title: Language lateralization as measured by dichotic VRT and recognition tasks.
abstract: A dichotic color-naming VRT task and a dichotic digits recognition task were administered. The first required the naming of five colors paired with their backward pronunciation: the second of five nonsimilar digits. Forty-eight right-handed male and female subjects were used, controlling for the factors of sex, handedness, and familial sinistrality. A highly significant left-ear advantage was obtained, suggesting that previous results of dichotic studies may only pertain to a limited class of phenomic stimuli. Results implicate different cerebral processes in the analysis of familiar and novel auditory and phenomic stimuli.
