Auditory asymmetry and strength of manual preference reexamined

Strong left- and right-handers, and moderate left- and right-handers administered a dichotic listening words test exhibited right ear advantages in direct proportion to their utilization of the right hand on 11 unimanual task. Strong left-handers exhibited a left ear advantage, and moderate left-handers failed to show laterality. Strong right-handers showed the largest right ear advantage. A brief review of the literature demonstrates that this trend is a consistent finding. One discrepant but often cited report (Dec, 1971) must be regarded with skepticism.
