聋人和听力读者对口语音素有不同的获取途径，这可能会影响书面语的表征和识别。我们使用事件相关电位( = )考察了聋人和听力正常成年人(共n个ERPs)在词汇判断任务中对480个英语单词词汇特征的反应。混合效应回归模型的结果表明：(A)视觉复杂性对聋人和听力读者产生相反方向的小效应，(B)相似的频率效应，但对聋人读者更早地移动，(C)正字法邻域密度对听力读者的影响更显著，以及(D)对聋人读者的具体性效应更明显。我们建议听力读者具有视觉单词表征，这种视觉表征与语音表征更紧密地结合在一起，从而产生更大的邻里密度的词汇中介效应。相反，聋人读者对其他信息来源的权重更大，导致更大的语义中介效应和对低水平视觉变量的反应改变。
Deaf and hearing readers have different access to spoken phonology which may affect the representation and recognition of written words. We used ERPs to investigate how a matched sample of deaf and hearing adults (total n = 90) responded to lexical characteristics of 480 English words in a go/no-go lexical decision task. Results from mixed effect regression models showed (a) visual complexity produced small effects in opposing directions for deaf and hearing readers, (b) similar frequency effects, but shifted earlier for deaf readers, (c) more pronounced effects of orthographic neighbourhood density for hearing readers, and (d) more pronounced effects of concreteness for deaf readers. We suggest hearing readers have visual word representations that are more integrated with phonological representations, leading to larger lexically-mediated effects of neighbourhood density. Conversely, deaf readers weight other sources of information more heavily, leading to larger semantically-mediated effects and altered responses to low-level visual variables.
