Introduction:
There are substantial differences in speech recognition performance of adult cochlear implant (CI) recipients. This study investigated the effects of cognitive function on speech recognition in CI recipients.
Methods:
The verbal working memory of 36 adults with unilateral CIs was tested using digit span tests. Attention and inhibition abilities were assessed by using the Stroop test (both congruent and incongruent tasks). Speech recognition in noise was measured using the Turkish matrix test.
Results:
A moderate negative correlation was observed between the critical signal-to-noise ratio obtained via speech recognition in noise test and the digit span test scores (backward and digit span total scores). There was no correlation between Stroop test scores and speech recognition in noise in CI recipients.
Conclusion:
The findings indicated that verbal working memory correlated well with speech recognition outcomes in adult CI recipients and that higher working memory capacity led to better speech recognition performance in noise.
