Ear differences in children at two years of age

Twenty-six children (13 boys and 13 girls) aged from 21 to 35.5 months were presented with a dichotic test of recognition of familiar words. There was no significant ear difference on average, however, a clear right-ear preference did emerge in children of right-handed parents. This contrasted with the tendency toward a left-ear preference that was exhibited by children with at least one left-handed parent.
