摘　　要：为探讨听障学生汉语语句唇读理解能力和唇读面部加工方式,本研究采用视频-图片匹配范式并结合眼动技术,考察小学、初中、高中听障学生的语句唇读理解能力和唇读面部加工方式。结果发现,小学和初中听障学生语句唇读理解正确率显著高于高中听障学生,表明小学和初中听障学生语句唇读理解能力更强。在眼动指标上,小学和初中听障学生的社会协调分数显著高于高中听障学生,小学和初中听障学生的眼部净注视时间比例、净注视点个数比例、平均瞳孔尺寸显著高于高中听障学生,高中听障学生口形净注视时间比例和净注视点个数比例显著高于小学听障学生。这表明听障学生唇读理解面部加工呈现整体加工方式,支持社会协调模式,但小学和初中听障学生整体加工效率更高,眼部和口部并行加工能力更强。This study employed the video picture matching paradigm and eye movement technology to investigate the Chinese sentence speechreading comprehension ability and facial processing of hearing-impaired students in primary,junior high and senior high schools.The results showed that the accuracy rate of speechreading comprehension of primary and junior high school students was significantly higher than that of senior high school students,which indicates that hearing-impaired students in primary and junior high schools had higher speechreading comprehension ability.In terms of eye movement indices,the Social Turning Score,the IA Dwell Time,IA Fixation,and Average Fix Pupil Size in the eye region were significantly higher in primary and junior high school students than in senior high school students,while the IA Dwell Time and IA fixation in the mouth region were significantly higher in senior high school students than in primary school students.The results showed that the hearing-impaired students all presented a global processing pattern in speechreading,which supported the Social Turning Pattern.However,the hearing-impaired students in primary and junior high schools had higher global processing efficiency and higher parallel processing ability in the eye and mouth regions.
