摘要
目的探讨精神分裂症患者汉字内隐记忆受损特征。方法对符合入组标准的精神分裂症患者40例及正常对照32例,选取高频、低频以及象形、非象形汉字,进行残词补笔测验,记录比较反应时和正确率。结果精神分裂症组旧词与新词任务反应时比较,差异具有统计学意义(P<0.01)。两组间总体残词补笔正确率及反应时指标比较,差异有统计学意义(P<0.01)。重复测量的方差分析显示:在象形性任务反应时结果中组别存在主效应(F=10.21,P<0.05),正确率结果显示组别存在主效应(F=7.96,P<0.05),未发现象形性主效应及二者的交互效应;在字频任务中,反应时结果字频存在主效应(F=19.90,P<0.05),组别存在主效应(F=16.53,P<0.05)。正确率结果显示,字频存在主效应(F=22.40,P<0.05),组别存在主效应(F=7.39,P<0.05)。结论精神分裂症患者存在汉字知觉驱动下的内隐记忆受损,不同词频之间反应时与正确率变化幅度与正常人未见差异。
Objective To explore the characteristics of implicit memory impairment of Chinese characters in schizophrenia patients.Methods A word stem complement test was carried out in 40 cases of schizophrenia and 32 cases of normal controls,including high frequency and low frequency,pictographic and non-pictographic Chinese characters.The reaction time(RT)and the accuracy were recorded and compared between two groups.Results In schizophrenia group,there was significant difference in RT between the old and the new word task(P<0.01).In the overall word stem complement task,there was significant difference in RT and accuracy between two groups(P<0.01).In the pictographic task,the main effect of group was found on RT results(F=10.21,P<0.05)and accuracy results(F=7.96,P<0.05).The main effect of pictography was not found in the word frequency task,the main effect of the word frequency was found on RT results(F=19.90,P<0.05),and the main effect of group was found on RT results(F=16.53,P<0.05).At the same time,the main effect of the word frequency was found on accuracy results(F=22.40,P<0.05),and the main effect of group was found on accuracy results(F=7.39,P<0.05).Conclusion The implicit memory of schizophrenia driven by Chinese character perception is damaged.In different word frequency,there is no difference in the amplitude of RT and accuracy between schizophrenia patients and normal controls.
