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. / Thesis (M.Sc.)-University of Durban-Westville, 1992.
