To examine multimodal spoken word-in-sentence recognition in children.
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.
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.
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.
研究儿童多模态单词句子识别。
进行了两项实验。在实验 1 中,评估了可使用多模态句子识别材料的最小年龄。在实验 2 中,检查了词汇难度和呈现模态的影响,以及正常听力儿童和植入人工耳蜗儿童的重测信度和效度。
使用设备至少 1 年的最小年龄为 3.25 岁的正常听力儿童和植入人工耳蜗的儿童,年龄不到 4 岁,能够完成多模态句子测试。两个组在所有模态中都能更准确地识别词汇简单的单词,而不是词汇难的单词,尽管在仅听觉模态中效果最大。两个组都显示出视听整合,在视听模态中获得的分数最高,其次是仅听觉模态和仅视觉模态。句子中单词的识别与孤立单词的识别相关。初步结果表明重测信度为中等至良好。
结果表明,可以使用为本次研究开发的材料评估儿童的视听单词句子识别。随着进一步的开发,这些材料有望成为听力损失儿童多模态句子识别的测试。
