目的：考察儿童多通道口语句中词再认的特点。实验一评估了使用多通道句子识别材料的最小年龄。实验二考察了听力正常儿童和人工耳蜗植入儿童的词汇难度和呈现通道效应，以及重测信度和效度。结果：3.25岁的听力正常儿童和4岁以下使用人工耳蜗器至少1年的儿童能够完成多通道句子测试。在不同的通道中，两组人识别句子中词汇简单的单词比识别词汇困难的单词更准确，尽管最大的影响发生在仅听觉通道中。两组都表现出视听整合，在视听通道中得分最高，其次是纯听觉和纯视觉通道。句子中单词的再认与孤立单词的再认相关。初步结果表明，重测信度为一般到良好。结论：本研究结果表明，儿童视听单词-句子再认能力可以用本研究开发的材料进行评估。随着进一步的发展，这些材料有望成为听力损失儿童的多模式句子识别测试。
Purpose: To examine multimodal spoken word-in-sentence recognition in children.Method: Two experiments were undertaken. In Experiment 1, the youngest age with which the multimodal sentence recognition materials could be used was evaluated. In Experiment 2, lexical difficulty and presentation modality effects were examined, along with test-retest reliability and validity in normal-hearing children and those with cochlear implants.Results: Normal-hearing children as young as 3.25 years and those with cochlear implants just under 4 years who have used their device for at least 1 year were able to complete the multimodal sentence testing. Both groups identified lexically easy words in sentences more accurately than lexically hard words across modalities, although the largest effects occurred in the auditory-only modality. Both groups displayed audiovisual integration with the highest scores achieved in the audiovisual modality, followed sequentially by auditory-only and visual-only modalities. Recognition of words in sentences was correlated with recognition of words in isolation. Preliminary results suggest fair-to-good test-retest reliability.Conclusions: The results suggest that children's audiovisual word-in-sentence recognition can be assessed using the materials developed for this investigation. With further development, the materials hold promise for becoming a test of multimodal sentence recognition for children with hearing loss.
