【摘要】：目的:本研究通過(guò)三個(gè)平行的行為學(xué)實(shí)驗(yàn)研究,分別探討陽(yáng)性陰性癥狀、面孔表情呈現(xiàn)方式、當(dāng)前情緒狀態(tài)與康復(fù)期精神分裂癥患者面孔表情類別知覺(jué)的關(guān)系,從而發(fā)現(xiàn)影響患者面孔表情類別知覺(jué)的因素,豐富精神分裂癥患者社會(huì)認(rèn)知方面的理論。從而為患者社會(huì)功能的康復(fù)提供實(shí)證研究資料,以期進(jìn)一步在干預(yù)患者的面孔表情類別知覺(jué)方面打好基礎(chǔ)。方法:(1)調(diào)查研究:在研究一中,采用自編一般資料調(diào)查問(wèn)卷刻畫(huà)了康復(fù)期精神分裂癥患者的一般情況,用陽(yáng)性陰性癥狀量表調(diào)查了患者的精神狀況,并通過(guò)此量表將精神分裂癥患者分為高分組和低分組,從而比較不同組別患者與正常對(duì)照組在面孔表情類別知覺(jué)上的差異。(2)實(shí)驗(yàn)研究:在三個(gè)研究中,均采用行為學(xué)實(shí)驗(yàn)的研究方法,通過(guò)控制患者的陽(yáng)性陰性高低分、面孔表情呈現(xiàn)方式和情緒誘發(fā)的性質(zhì),對(duì)患者和正常對(duì)照組的面孔表情界限及表情類別反應(yīng)斜率進(jìn)行比較,找出患者在面孔表情類別知覺(jué)上的差異。結(jié)果:(1)在陰性陽(yáng)性癥狀與面孔表情類別知覺(jué)的關(guān)系研究中,陽(yáng)性癥狀高、低分組與正常對(duì)照組,在面孔表情類別界限及反應(yīng)斜率上的差異均沒(méi)有統(tǒng)計(jì)學(xué)意義(p0.05)。陰性癥狀高、低分組與正常對(duì)照組相比較,在面孔表情類別界限上差異顯著,具有統(tǒng)計(jì)學(xué)意義(p0.05);在反應(yīng)斜率上差異不顯著,沒(méi)有達(dá)到統(tǒng)計(jì)學(xué)意義(p0.05)。(2)在面孔表情呈現(xiàn)方式對(duì)面孔表情類別知覺(jué)的影響研究中,兩組在類別界限上的被試類型主效應(yīng)不顯著F(1,140)=2.43,p=0.12,面孔表情呈現(xiàn)方式在類別界限上的主效應(yīng)顯著F(1.63,227.76)=99.26,p0.001,被試類型與面孔表情呈現(xiàn)方式間的交互作用顯著F(1.63,227.76)=18.72,p0.001;兩組在反應(yīng)斜率上的被試類型主效應(yīng)顯著F(1,140)=17.70,p0.001,面孔表情呈現(xiàn)方式在反應(yīng)斜率上的主效應(yīng)顯著F(2,280)=7.20,p=0.001,被試類型與面孔表情呈現(xiàn)方式間的交互作用不顯著F(2,280)=1.10,p=0.335。(3)在情緒誘發(fā)性質(zhì)對(duì)面孔表情類別知覺(jué)的影響研究中,兩組在類別界限上的被試類型主效應(yīng)不顯著F(1,108)=2.35,p=0.128,情緒誘發(fā)性質(zhì)在類別界限上的主效應(yīng)顯著F(1.50,162.14)=59.49,p0.001,被試類型與情緒誘發(fā)性質(zhì)間的交互作用顯著F(1.50,162.14)=36.33,p0.001;兩組在反應(yīng)斜率上的被試類型主效應(yīng)顯著F(1,108)=10.06,p=0.002,情緒誘發(fā)性質(zhì)在反應(yīng)斜率上的主效應(yīng)顯著F(2,216)=6.80,p=0.001,被試類型與情緒誘發(fā)性質(zhì)間的交互作用邊緣顯著F(2,216)=2.90,p=0.057。結(jié)論:對(duì)于康復(fù)期精神分裂癥患者,其面孔表情類別知覺(jué)的實(shí)驗(yàn)研究具有以下結(jié)論:(1)陰性癥狀會(huì)影響患者的面孔表情類別知覺(jué),主要影響表情類別界限。陰性癥狀越嚴(yán)重,患者越容易將模糊的表情分類為悲傷而非高興。(2)面孔表情呈現(xiàn)方式會(huì)影響患者的面孔表情類別知覺(jué)。在類別界限方面,當(dāng)觀察完整面孔時(shí),患者分類高興、悲傷表情的面孔表情類別知覺(jué)與常人類似;當(dāng)觀察下半部分面孔時(shí),患者容易將模糊的表情分類為高興;當(dāng)觀察上半部分面孔時(shí),患者容易將模糊的表情分類為悲傷。說(shuō)明患者在面孔信息不完整的條件下,對(duì)模糊表情的分類具有明顯的障礙。在反應(yīng)斜率方面,在三種面孔表情呈現(xiàn)方式下,患者組的反應(yīng)斜率均顯著小于正常對(duì)照組,說(shuō)明其對(duì)類別界限的敏感度比正常人差。且在觀察上半部分面孔時(shí)反應(yīng)斜率顯著小于其他呈現(xiàn)方式下的反應(yīng)斜率,患者對(duì)眼部的類別界限最不敏感。(3)情緒誘發(fā)性質(zhì)更容易影響正常人的面孔表情類別知覺(jué),對(duì)患者的面孔表情類別知覺(jué)影響相對(duì)較小。在類別界限方面,在中性和正性情緒誘發(fā)條件下,患者的類別界限類似于正常人;在負(fù)性情緒誘發(fā)條件下,患者更容易將模糊不清的面孔表情識(shí)別為具有高興的表情�；颊咴谌N情緒誘發(fā)條件下,類別界限均比較接近,而正常對(duì)照組均相互分離。在反應(yīng)斜率方面,患者的反應(yīng)斜率并不隨情緒誘發(fā)性質(zhì)的改變而改變。
[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.
