Central auditory processing performance of male and female stutterers and nonstutterers was compared on a battery of central auditory tests. Thirty stutterers (15 male and 15 female) with a mean age of 23.10 years (17.2-31 years) comprised the experimental group, and 30 nonstutterers (15 male and 15 female) with a mean age of 22.2 years(17-32 years) comprised the control group. The test battery included dichotic (DCV test, ssw test, eST) and monotic (SSI-ICM test, ARLT) tests. Stutterers performed significantly poorer than nonstutterers on various parameters of individual tests. The stutterers' performance on the test battery was varied : 8(26.6%) stutterers passed all tests in the battery; 7(23.3%) failed dichotic tests only; 15(50%) failed dichotic and monotic tests of which 2(6.6%) failed monotic tests. Pass/fail rates indicated that although 15 (50%) nonstutterers failed the battery 22(73.2%) stutterers failed. This result confirmed that stutterers performed significantly differently from nonstutterers on the test battery( X?= 19.87 , df=l; p<0.05). Male/famale comparisons for nonstutterers indicated no significant differences (p>0.05) on individual tests except on the ARLT where males obtained longer latencies than females. Pass /fail rates on the test battery confirmed no statistically significant (X~= 0.133 , df=l; p> 0.05) performance differences between male and female nonstutterers. For stutterers, although male performance was poorer than female performance on various parameters of individual tests ,the performance differences were not significant (p>0.05). However, pass/fail performance on the test battery indicated that significantly more males (13) than females (9) failed the test battery ( X2 = 8.66 df=l, p<0.05). The results are discussed in terms of the literature and theoretical and clinical implications are presented and discussed.
