【摘要】：目的:本研究通过三个平行的行为学实验研究,分别探讨阳性阴性症状、面孔表情呈现方式、当前情绪状态与康复期精神分裂症患者面孔表情类别知觉的关系,从而发现影响患者面孔表情类别知觉的因素,丰富精神分裂症患者社会认知方面的理论。从而为患者社会功能的康复提供实证研究资料,以期进一步在干预患者的面孔表情类别知觉方面打好基础。方法:(1)调查研究:在研究一中,采用自编一般资料调查问卷刻画了康复期精神分裂症患者的一般情况,用阳性阴性症状量表调查了患者的精神状况,并通过此量表将精神分裂症患者分为高分组和低分组,从而比较不同组别患者与正常对照组在面孔表情类别知觉上的差异。(2)实验研究:在三个研究中,均采用行为学实验的研究方法,通过控制患者的阳性阴性高低分、面孔表情呈现方式和情绪诱发的性质,对患者和正常对照组的面孔表情界限及表情类别反应斜率进行比较,找出患者在面孔表情类别知觉上的差异。结果:(1)在阴性阳性症状与面孔表情类别知觉的关系研究中,阳性症状高、低分组与正常对照组,在面孔表情类别界限及反应斜率上的差异均没有统计学意义(p0.05)。阴性症状高、低分组与正常对照组相比较,在面孔表情类别界限上差异显著,具有统计学意义(p0.05);在反应斜率上差异不显著,没有达到统计学意义(p0.05)。(2)在面孔表情呈现方式对面孔表情类别知觉的影响研究中,两组在类别界限上的被试类型主效应不显著F(1,140)=2.43,p=0.12,面孔表情呈现方式在类别界限上的主效应显著F(1.63,227.76)=99.26,p0.001,被试类型与面孔表情呈现方式间的交互作用显著F(1.63,227.76)=18.72,p0.001;两组在反应斜率上的被试类型主效应显著F(1,140)=17.70,p0.001,面孔表情呈现方式在反应斜率上的主效应显著F(2,280)=7.20,p=0.001,被试类型与面孔表情呈现方式间的交互作用不显著F(2,280)=1.10,p=0.335。(3)在情绪诱发性质对面孔表情类别知觉的影响研究中,两组在类别界限上的被试类型主效应不显著F(1,108)=2.35,p=0.128,情绪诱发性质在类别界限上的主效应显著F(1.50,162.14)=59.49,p0.001,被试类型与情绪诱发性质间的交互作用显著F(1.50,162.14)=36.33,p0.001;两组在反应斜率上的被试类型主效应显著F(1,108)=10.06,p=0.002,情绪诱发性质在反应斜率上的主效应显著F(2,216)=6.80,p=0.001,被试类型与情绪诱发性质间的交互作用边缘显著F(2,216)=2.90,p=0.057。结论:对于康复期精神分裂症患者,其面孔表情类别知觉的实验研究具有以下结论:(1)阴性症状会影响患者的面孔表情类别知觉,主要影响表情类别界限。阴性症状越严重,患者越容易将模糊的表情分类为悲伤而非高兴。(2)面孔表情呈现方式会影响患者的面孔表情类别知觉。在类别界限方面,当观察完整面孔时,患者分类高兴、悲伤表情的面孔表情类别知觉与常人类似;当观察下半部分面孔时,患者容易将模糊的表情分类为高兴;当观察上半部分面孔时,患者容易将模糊的表情分类为悲伤。说明患者在面孔信息不完整的条件下,对模糊表情的分类具有明显的障碍。在反应斜率方面,在三种面孔表情呈现方式下,患者组的反应斜率均显著小于正常对照组,说明其对类别界限的敏感度比正常人差。且在观察上半部分面孔时反应斜率显著小于其他呈现方式下的反应斜率,患者对眼部的类别界限最不敏感。(3)情绪诱发性质更容易影响正常人的面孔表情类别知觉,对患者的面孔表情类别知觉影响相对较小。在类别界限方面,在中性和正性情绪诱发条件下,患者的类别界限类似于正常人;在负性情绪诱发条件下,患者更容易将模糊不清的面孔表情识别为具有高兴的表情。患者在三种情绪诱发条件下,类别界限均比较接近,而正常对照组均相互分离。在反应斜率方面,患者的反应斜率并不随情绪诱发性质的改变而改变。
[Abstract]:Objective: To explore the relationship between positive negative symptoms, facial expression, current emotional state and facial expression category perception in schizophrenic patients at convalescence, and to find out the factors that affect the perception of facial expressions and to enrich the social cognition of schizophrenic patients through three parallel behavioral studies. It provides an empirical study for the rehabilitation of the social function of the patient in order to further improve the perception of the facial expressions of the patients. Method: (1) research: in the first study, the general information questionnaire was used to describe the general situation of schizophrenic patients in the recovery period, and the positive negative was negative. The symptom scale investigated the mental status of the patients and divided the schizophrenic patients into high and low groups by this scale, and compared the differences in the perception of facial expressions in different groups of patients and the normal control group. (2) experimental study: in the three studies, the methods of using behavioral experiments were used to control the patients. The positive negative high and low score, the expression pattern of face expression and the character of emotional induced, compare the facial expression boundary and the expression category response slope of the normal control group, and find out the difference in the perception of the facial expression category. (1) the positive symptoms are positive in the relationship between the negative positive symptoms and the facial expression category perception. There was no statistical significance (P0.05) on the difference between the facial expression category boundaries and the response slope. The negative symptoms were higher and the lower group was significantly different from the normal control group. The difference was statistically significant (P0.05) in the face expression category boundaries (P0.05); there was no significant difference in the response slope, and no statistical difference was reached. (P0.05). (2) in the study of the influence of face expression on the perception of facial expression category, the main effect of the two groups on category boundaries was not significantly F (1140) =2.43, p=0.12, and the main effect of face expression on category boundaries was F (1.63227.76) =99.26, p0.001, the type of subjects and the expression of face expression. The interaction between the two groups was significantly F (1.63227.76) =18.72, p0.001, and the main effects of the two groups on the reaction slope were significantly F (1140) =17.70, p0.001, and the main effect of the face expression pattern on the reaction slope was F (2280) =7.20, p=0.001, and the interaction between the trial type and the face expression pattern was not significantly F (2280) =1.10. 3) in the study of the influence of emotional evoked properties on the perception of facial expression categories, the main effects of the two groups on category boundaries were not significantly F (1108) =2.35, p=0.128, and the main effect of emotional evoked properties on category boundaries was significant F (1.50162.14) =59.49, p0.001, and the interaction between the type and the emotional evoked properties was significant F (1.50162.1). 4) =36.33, p0.001; the main effects of the two groups on the reaction slope were significantly F (1108) =10.06, p=0.002, the main effect of the emotional induced properties on the reaction slope was F (2216) =6.80, p=0.001, the interaction between the type and the emotional evoked properties was significantly F (2216) =2.90, p=0.057. conclusion: for schizophrenia patients in the rehabilitation period, The experimental research on the perception of facial expression category has the following conclusions: (1) negative symptoms can affect the perception of facial expression category, which mainly affects the category boundary of expression. The more serious the negative symptoms are, the more easy the patient is to classify the vague expression to sadness rather than happiness. (2) the expression of facial expression will affect the patient's facial expression category knowledge. In terms of category boundaries, when a complete face was observed, the patient was classified as happy, and the perception of the facial expression of the sad expression was similar to that of the ordinary person. When the lower part of the face was observed, the patient easily classified the vague expression to happiness; when the upper part of the face was observed, the patient classified the vague expression to sadness. Under the condition of incomplete information, there is an obvious obstacle to the classification of fuzzy expression. In the aspect of reaction slope, the response slope of the patient group is significantly less than that of the normal control group under the three facial expression presentation, indicating that the sensitivity of the group is worse than the normal person. And the reaction slope of the half face is significantly smaller. In other presentation, the patient has the most insensitivity to the category boundary of the eye. (3) emotional induced nature is more likely to affect the perception of the normal person's facial expression category, and the effect on the perception of the facial expression category is relatively small. In the category boundary, the category boundary category of the patient under the neutral and positive emotion induced conditions. It is similar to normal people; under the negative emotion induced condition, the patient is more likely to recognize the ambiguous face expression as a happy expression. The patient is close to each other under three emotional conditions, while the normal control group separates each other. Change and change.
