Left-right Differences in the Perception of Melodies

Normal subjects were given two auditory tests, one consisting of spoken digits presented dichotically, the other of melodies presented dichotically. On the Digits test, the score for the right ear was higher than for the left (as previously established), and on the Melodies test the score for the left ear was higher than for the right. These findings were related to the different roles of the right and left hemispheres of the brain in verbal and nonverbal perception.
