The results were as follows： 1. In the study with words, they answered to 38.93 ±8.78 (53.40%) out of 72 words of the dichotic listening test, either correctly or incorrectly； the number of correct answers was 31.51 ±10.30(42.90%) and that of incorrect ones was 7.41 ±4.30 (10.52%) words. 2. In the above study of dichotic listening, both the scores of total answers and correct answers were significantly higher in female than in male (P<.005). 3.
