title: Music affects learning of a braille-like task by sighted subjects.
abstract: 24 consistently right-handed male college students felt sets of four Braille symbols with either the right or the left index finger and identified by touch alone which two of the four symbols in each set were identical. During the task music was played to either the right ear, the left ear, both ears, or neither ear. Significantly fewer errors were made when the music was in the ear contralateral to whichever hand performed the task. The ipsilateral, binaural, and no-music groups did not differ significantly from each other. It is suggested that monaural music to the ear contralateral to the engaged hand led to reduced interhemispheric competition acting on the hemisphere controlling the hand. Such a facilitating effect may be of practical importance in tasks during which one hemisphere received the bulk of the task-related sensory input and/or processes the final order from the brain to the task-related muscles.
