非言语声音和言语声音表征关系的研究

摘要

Objective To study the relationship between representations of verbal sound and non-verbal sound in the brain.Methods 39 patients with brain injury and 39 healthy volunteers were recruited in this study. They were tested with the sound-verification task (a non-verbal sound test) and the sound attribute judgment task (a verbal sound test). The software developed by Crawford and Garthwaite was used for data analysis. Results Group analysis revealed a positive correlation between the verbal sound test and non-verbal sound test. As for case analysis, some patients were impaired in the comprehension of verbal sound test, but normal in the comprehension of non-verbal sound test. In contrast, some patients were impaired in the comprehension of non-verbal sound test, but normal in the comprehension of verbal sound test. Conclusion Verbal sound and non-verbal sound are represented independently in the brain. In the process of language rehabilitation of aphasia, attention should not only be paid to verbal sound training, but also to non-verbal sound training.%目的 研究在汉语背景下,非言语声音和言语声音在大脑中的表征关系.方法 对39例脑损伤患者和39例正常对照组进行声音-图片核证测验和声音属性判断,采用Crawford和Garthwaite的分离软件对患者的数据进行分析.结果 群组分析显示,患者在言语声音理解测验和非言语声音理解测验的成绩显著正相关;个体分析显示,部分患者表现出非言语声音理解正常,言语声音理解损伤;部分患者则表现出言语声音理解正常,非言语声音理解损伤.结论 在汉语背景下,言语声音和非言语声音在大脑中是独立表征的.失语症患者的语言康复过程中,不仅要重视言语声音的训练,还要重视非言语声音的训练.
