【摘要】：目的:研究汉语听写障碍儿童在形音跨通道捆绑过程中的视觉和听觉跨通道优势。方法:以听写障碍儿童21名,正常发展儿童21名为被试。采用变化检测范式,以几何图形为视觉刺激材料,以单音节男声为听觉刺激材料,通过考察两组儿童在探测形音跨通道不一致、视觉单通道不一致、听觉单通道不一致三种条件下的正确率,探索听写障碍儿童与正常发展儿童在形音捆绑过程中的跨通道整合优势以及视觉或听觉单通道的优势效应。结果:听写障碍儿童在视听跨通道加工条件下显著地低于正常发展儿童,在视觉单通道条件下两者差异不显著,在听觉单通道条件下两者差异达到边缘显著。结论:听写障碍儿童的形音捆绑缺陷来自于跨通道本身的缺陷。正常听写儿童可能具有听觉单通道加工优势。听写障碍儿童在形音捆绑加工中有和正常听写儿童相同的视觉通道优势,但有可能在听觉通道中不占优势。
[Abstract]:Objective: to study the visual and auditory cross-channel advantages of Chinese dictation disorder children in the process of cross-channel binding. Methods: 21 children with dictation disorder and 21 children with normal development were enrolled in this study. Using geometric figure as visual stimulus material and monosyllabic male sound as auditory stimulus material, the correct rates of two groups of children were investigated under three conditions of detecting cross-channel inconsistency, visual single-channel inconsistency and auditory single-channel inconsistency. To explore the advantages of cross-channel integration of dictation children with normal development in the binding process of shape and sound and the dominant effect of visual or auditory single channel. Results: dictation in children with audiovisual cross-channel processing significantly under the conditions of audiovisual cross-channel processing. Lower than the normal development of children, There was no significant difference between the two under the condition of single visual channel. Under the condition of single auditory channel, the difference between the two is significant. Conclusion: the defect of shape and sound binding of dictation children comes from the defect of cross-channel itself. The normal dictation children may have the advantage of auditory single-channel processing. Disabled children have the same visual channel advantages as normal dictation children. But it may not be dominant in the auditory pathway.
