To investigate differences in executive functioning between deaf children with cochlear implants (CIs) and normal-hearing (NH) peers. The cognitive effects of auditory deprivation in childhood may extend beyond speech-language skills to more domain-general areas including executive functioning.
Executive functioning skills in a sample of 53 prelingually deaf children, adolescents, and young adults who received CIs prior to age 7 years and who had used their CIs for ≥7 years were compared with age- and nonverbal IQ-matched NH peers and with scale norms.
Despite having above average nonverbal IQ, the CI sample scored lower than the NH sample and test norms on several measures of short-term/working memory, fluency-speed, and inhibition-concentration. Executive functioning was unrelated to most demographic and hearing history characteristics.
Prelingual deafness and long-term use of CIs was associated with increased risk of weaknesses in executive functioning.
研究植入人工耳蜗的聋童与正常听力（NH）同龄儿童之间执行功能的差异。儿童时期听觉剥夺的认知影响可能不仅限于言语语言技能，还包括更广泛的领域，包括执行功能。
对 53 名在 7 岁之前接受人工耳蜗植入并使用人工耳蜗 ≥7 年的语前聋儿童、青少年和年轻人样本的执行功能技能进行比较，与年龄和非言语智商匹配的 NH 同龄人和量表标准进行比较。
尽管他们的非言语智商高于平均水平，但 CI 样本在几项短期/工作记忆、流畅性-速度和抑制-浓度的测量中，得分低于 NH 样本和测试标准。执行功能与大多数人口统计学和听力史特征无关。
语前聋和长期使用人工耳蜗与执行功能薄弱的风险增加有关。
