由于听力损失，植入人工耳蜗（CI）的成年人会自我报告执行功能（EF）技能比听力正常（NH）的同龄人差，这些EF技能与语音识别任务的表现有关。EF是指一组负责目标导向活动中行为和情绪调节的高阶神经认知技能，并且已发现CI儿童的EF比其NH年龄匹配的同龄人更差。此外，越来越多的证据表明，神经认知技能，包括一些EF技能，有助于通过CI识别语音的能力。入组了30名患有CI的舌后唇腭裂成年人和42名年龄匹配的NH成年人。参与者和他们的配偶或重要的其他人（告密者）完成了有效的自我报告或告密者报告的EF，执行功能的行为评定量表-成人（BRIEF-A）。CI用户的语音识别技能进行了评估，在安静的句子识别的几个措施。NH同行进行了测试，识别相同的语音刺激的噪声声码版本。CI用户自我报告的EF任务的转移和任务监测的困难。在CI用户，语音识别的措施与几个自我报告的EF技能。目前的研究结果提供了进一步的证据表明，神经认知因素，包括特定的EF技能，可能会下降与听力损失，以及这些EF技能有助于语音处理退化的听力条件下。
As a result of their hearing loss, adults with cochlear implants (CIs) would self-report poorer executive functioning (EF) skills than normal-hearing (NH) peers, and these EF skills would be associated with performance on speech recognition tasks. EF refers to a group of high order neurocognitive skills responsible for behavioral and emotional regulation during goal-directed activity, and EF has been found to be poorer in children with CIs than their NH age-matched peers. Moreover, there is increasing evidence that neurocognitive skills, including some EF skills, contribute to the ability to recognize speech through a CI. Thirty postlingually deafened adults with CIs and 42 age-matched NH adults were enrolled. Participants and their spouses or significant others (informants) completed well-validated self-reports or informant-reports of EF, the Behavior Rating Inventory of Executive Function – Adult (BRIEF-A). CI users’ speech recognition skills were assessed in quiet using several measures of sentence recognition. NH peers were tested for recognition of noise-vocoded versions of the same speech stimuli. CI users self-reported difficulty on EF tasks of shifting and task monitoring. In CI users, measures of speech recognition correlated with several self-reported EF skills. The present findings provide further evidence that neurocognitive factors, including specific EF skills, may decline in association with hearing loss, and that some of these EF skills contribute to speech processing under degraded listening conditions.
