接受人工耳蜗植入（CI）的听力损失儿童的不同听觉体验可能会影响词汇和概念信息的整合。在这里，我们测量了事件相关电位在CI使用儿童（n = 29，平均年龄= 81个月）和典型的听力儿童（n = 19，平均年龄= 75个月）的词-图片启动任务，而他们看到的视听词启动和图片的目标，语义一致或不一致。在两组中，语义相关性在图片开始后300- 500 ms调制ERP幅度，表明N400语义效应。关键的是，CI使用儿童的反应，不相关的对显着比听力儿童的反应更消极。组间差异反映在与P2反应相关的较早150- 275 ms时间窗内。目前的研究结果表明，注意和/或策略的差异影响语义处理，并有助于N400组之间观察到的差异。
Differential auditory experiences of children with hearing-loss who receive cochlear implants (CIs) may influence the integration of lexical and conceptual information. Here we measured event-related potentials during a word-picture priming task in CI-using children (n = 29, mean age = 81 months) and typically-hearing children (n = 19, mean age = 75 months) while they viewed audiovisual-word primes and picture targets that were semantically congruent or incongruent. In both groups, semantic relatedness modulated ERP amplitude 300–500ms after picture onset, signifying an N400 semantic effect. Critically, the CI-using children’s responses to unrelated pairs were significantly more negative than hearing children’s responses. Group differences were mirrored in an earlier 150–275ms time window associated with a P2 response. The present findings suggest attentional and/or strategic differences impact semantic processing and contribute to the N400 differences observed between groups.
