汉语母语者视听双通道言语知觉的特点及发展研究

以30名小学二年级学生2、4名小学五年级学生和29名大学一年级学生为被试,运用McGurk效应研究范式对汉语母语者视听双通道言语知觉的表现特点、发展趋势等问题进行了探讨,三个年龄阶段被试均接受纯听和视听两种条件下的测查,被试的任务是出声报告自己听到的刺激。结果发现:(1)汉语为母语的二年级小学生、五年级小学生和大学生在自然听力环境下的单音节加工中都受到视觉线索的影响,表现出了McGurk效应;(2)二年级小学生、五年级小学生和大学生受视觉言语影响的程度,也就是McGurk效应的强度没有显著差异,没有表现出类似英语母语者的发展趋势。该结果支持了McGurk效应"普遍存在"的假说。

The Characteristics and Development of Audiovisual Speech Perception in Native Chinese Speakers

Using the McGurk paradigm,the present study explored the characteristics and developmental trends of audiovisual speech perception of Chinese children and adults.30 primary school students in Grade 2,24 students in Grade 5,and 29 freshmen were requested to repeat the monosyllable presented in the audiovisual and audio-only modality.The results showed that speech perception were significantly affected by the visual cues for all the subjects,but the magnitude of influence showed no age difference.This results support the hypothesis that "McGurk effect is linguistic universal".
