Deaf children with cochlear implants (CIs) show poorer verbal working memory compared to normal-hearing (NH) peers, but little is known about their verbal learning and memory (VLM) processes involving multi-trial free recall.
Children with CIs were compared to NH peers using the California Verbal Learning Test for Children (CVLT-C).
Participants were 21 deaf (before age 6 months) children (6-16 years old) implanted prior to age 3 years, and 21 age-IQ matched NH peers.
Results revealed no differences between groups in number of words recalled. However, CI users showed a pattern of increasing use of serial clustering strategies across learning trials, whereas NH peers decreased their use of serial clustering strategies. In the CI sample (but not in the NH sample), verbal working memory test scores were related to resistance to the build-up of proactive interference, and sentence recognition was associated with performance on the first exposure to the word list and to the use of recency recall strategies.
Children with CIs showed robust evidence of VLM comparable to NH peers. However, their VLM processing (especially recency and proactive interference) was related to speech perception outcomes and verbal WM in different ways from NH peers.
与听力正常的同龄人相比，植入人工耳蜗（CI）的聋儿表现出较差的言语工作记忆，但对于他们涉及多次自由回忆的言语学习和记忆（VLM）过程知之甚少。
使用儿童加利福尼亚言语学习测试（CVLT-C）将植入人工耳蜗的儿童与听力正常的同龄人进行比较。
参与者为21名（6个月前失聪）在3岁前植入人工耳蜗的聋儿（6 - 16岁），以及21名年龄和智商匹配的听力正常的同龄人。
结果显示两组在回忆单词数量上没有差异。然而，植入人工耳蜗的使用者在学习试验中表现出越来越多地使用系列聚类策略的模式，而听力正常的同龄人则减少了对系列聚类策略的使用。在植入人工耳蜗的样本中（但在听力正常的样本中没有），言语工作记忆测试分数与对前摄干扰积累的抵抗力有关，并且句子识别与首次接触单词列表时的表现以及近因回忆策略的使用有关。
植入人工耳蜗的儿童表现出与听力正常的同龄人相当的VLM有力证据。然而，他们的VLM处理（特别是近因和前摄干扰）与听力正常的同龄人在不同方面与言语感知结果和言语工作记忆有关。
