The sex difference in dichotic listening: multiple negative findings.
Verbal dichotic listening tests were administered to 477 normal, right-handed adults in five consecutive experiments. None of the five separate analyses yielded a significant sex difference in degree of ear asymmetry, nor was a significant difference found when data were pooled. Supplemental analyses provided some evidence of a sex difference among subjects without familial sinistrality. Nonetheless, subjects' sex accounts for a very small proportion of the total variance in ear asymmetry.
