【摘要】：目的了解精神分裂症患者注意障碍的认知神经心理学特征。通过线段等分试验证实精神分裂症患者是否存在单侧空间注意障碍，而通过情绪面孔嵌合试验进一步探讨精神分裂症患者在不同情绪面孔识别干扰下是否存在空间注意障碍。通过以上两种试验方法探讨精神分裂症患者在注意偏向上是否存在相关性，并为临床注意偏向的筛查提供一种新方法。方法试验对象为32例门诊及住院精神分裂症患者和32名年龄、性别、文化程度及简易精神状态量表（Mini-mental state examination，MMSE）评分等相匹配的健康人。线段等分试验：两组被试要求标出20cm长度线段的主观中点，观察线段的偏移值和偏移率。情绪面孔嵌合试验：两组被试要求观察由中性面孔、正性情绪面孔（喜）和负性情绪面孔（怒、恐）构成的嵌合图形组，并按键选择这些嵌合图形中情绪程度较深的一张，据此计算出偏移率。同时比较上述两种试验结果是否存在相关性。结果在线段等分试验中，线段长度为20CM，两组的偏移值及偏移率均为负值，但精神分裂症组的偏移率较正常对照组高，差异有统计学差异（Z=-3.56，P0.01）。在情绪面孔嵌合试验中，两组在本顿面孔识别试验中的差异无统计学意义（P0.05）。在情绪为喜的面孔嵌合试验中，精神分裂症组的偏移率均比对照组高，差异有统计学意义（Z=-2.04，P 0.01）；精神分裂症组与对照组的情绪（喜）面孔嵌合和线段等分之间偏移率正相关（r=0.68，P 0.01）；而在情绪为怒和恐的嵌合面孔试验中，患者组的偏移率与对照组比较，差异无统计学意义（P0.05）。结论精神分裂症患者在正性情绪（喜）面孔嵌合试验和线段等分试验中均表现为注意明显左偏，提示患者右侧空间注意受损，可能与左侧脑半球功能障碍有关，，并且上述两种试验正相关。两组被试在负性情绪（怒，恐）的嵌合面孔试验中的差异无统计学意义，提示患者可能对于负性情绪面孔识别上存在一定障碍；
[Abstract]:Objective To investigate the cognitive neuropsychological characteristics of attention deficit in patients with schizophrenia .

Methods Thirty - two patients with schizophrenia and 32 patients with schizophrenia and 32 age , sex , culture degree and Mini - mental state examination ( MMSE ) were divided into two groups .

Results In the line segment and the like , the line segment length was 20CM , the offset values and the offset rate of the two groups were negative , but the deviation rate of the schizophrenia group was higher than that of the normal control group ( Z = - 3.56 , P0.01 ) . There was no significant difference between the two groups ( P0.05 ) in the experiment of emotion face chimerism . In the emotion - pleasing face chimerism test , the deviation rate of the schizophrenia group was higher than that of the control group ( Z = - 2.04 , P 0.01 ) ;
There was a positive correlation between schizophrenia group and control group ( r = 0.68 , P 0.01 ) .
Compared with the control group , there was no significant difference between the patients ' group and the control group ( P0.05 ) .

Conclusion There is no significant difference between the positive emotion ( xi ) face fitting test and the line segment in schizophrenic patients , which suggests that the right space of the patient is damaged and may be related to the left hemisphere dysfunction , and the two tests are positive . The difference between the two groups is not statistically significant in the fitting face test of negative emotion ( anger , fear ) , and it is suggested that the patient may have a certain obstacle to the negative emotion facial recognition ;
