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.
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.
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.
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.
成人人工耳蜗（CI）使用者的言语识别表现存在显著差异。本研究旨在探究认知功能对 CI 使用者言语识别的影响。
采用数字跨度测试评估 36 名单侧 CI 使用者的言语工作记忆，通过斯特鲁普测试（一致和不一致任务）评估注意力和抑制能力。采用土耳其矩阵测试测量噪声下的言语识别。
噪声下言语识别测试的临界信噪比与数字跨度测试（顺背和总得分）结果呈中度负相关。CI 使用者的斯特鲁普测试得分与噪声下的言语识别无相关性。
研究结果表明，言语工作记忆与成人 CI 使用者的言语识别结果密切相关，较高的工作记忆能力导致噪声下更好的言语识别表现。
