【摘要】：抑郁癥是一種比較常見的精神疾病,具有較高的患病率。抑郁癥患者對(duì)社交過程中他人面部表情的微弱變化不能正確識(shí)別并作出反應(yīng),這一缺陷可能與抑郁癥患者明顯的社交障礙有關(guān)。抑郁癥患者存在面部表情識(shí)別障礙(Kohler,Hoffman,Eastman,Healey,Moberg,2011),社交缺陷是抑郁癥形成和持續(xù)的重要原因(JoormannGotlib,2006),而情緒性面部表情加工受損可能會(huì)導(dǎo)致社交缺陷。研究抑郁人群(即單相和雙相抑郁癥)情緒過程的行為文獻(xiàn)指出,與健康控制相比,抑郁被試表現(xiàn)出中斷的情緒加工,由較弱的表現(xiàn)和/或延遲的反應(yīng)潛伏期為指標(biāo)。然而當(dāng)前的研究大多數(shù)集中在重度抑郁患者,對(duì)具有抑郁傾向患者對(duì)情緒刺激的反應(yīng)偏向和敏感性不能進(jìn)行一個(gè)很好的預(yù)測(cè)作用,不能確定在抑郁傾向患者進(jìn)行面孔加工時(shí)出現(xiàn)缺陷的信息加工位置,當(dāng)前的研究采用的實(shí)驗(yàn)材料和研究范式并沒有得出一個(gè)統(tǒng)一的結(jié)果。因此,本實(shí)驗(yàn)采用漸變的面孔刺激和類別知覺實(shí)驗(yàn)范式,考察和正常人群相比,抑郁傾向大學(xué)生的面部表情反應(yīng)偏向和敏感性的差異。本研究包括三個(gè)實(shí)驗(yàn):實(shí)驗(yàn)一抑郁傾向大學(xué)生對(duì)漸變的面部表情的反應(yīng)偏向和對(duì)變化的知覺敏感性。實(shí)驗(yàn)二在實(shí)驗(yàn)一的基礎(chǔ)上探討對(duì)在漸變的面部表情產(chǎn)生偏差的抑郁傾向大學(xué)生對(duì)漸變的純粹面部表情的反應(yīng)偏向知覺敏感性。實(shí)驗(yàn)三抑郁人群面部表情類別知覺的ERP研究,分析抑郁組和控制組在40%、70%和100%的情緒性表情上的N2和P3波的波幅和潛伏期差異。結(jié)果如下:1.抑郁組和控制組在辨別憤怒-悲傷和高興-悲傷的表情連續(xù)體時(shí)都表現(xiàn)出對(duì)靠近悲傷表情原型的高的正確率,但兩組之間的差異并沒有顯著。利用從中性表情漸變到完全情緒性表情的連續(xù)體將憤怒-悲傷表情連續(xù)體分離開來,發(fā)現(xiàn)和控制組相比,抑郁組在辨別類內(nèi)的憤怒表情對(duì)時(shí)表現(xiàn)出更高的正確率,說明兩組在憤怒表情辨別上存在顯著差異,和控制組相比,抑郁組對(duì)憤怒表情更敏感。2.在識(shí)別任務(wù)中,和控制組相比,抑郁組表現(xiàn)出對(duì)負(fù)性面孔刺激的反應(yīng)偏向,避免對(duì)高興表情的識(shí)別,并且在憤怒-悲傷表情連續(xù)體上表現(xiàn)出對(duì)憤怒表情的反應(yīng)偏向,但是在敏感性上兩組沒有表現(xiàn)出差異。在中性-表情連續(xù)體中抑郁組也表現(xiàn)出同樣的反應(yīng)偏向:和控制組相比,在中性-憤怒連續(xù)體中,抑郁組更多把模糊表情識(shí)別為憤怒,而在中性-高興表情連續(xù)體中則更多把模糊表情識(shí)別為中性,避免識(shí)別為高興。3.在識(shí)別反應(yīng)時(shí)上,無論是表情-表情連續(xù)體還是中性-表情連續(xù)體,對(duì)靠近連續(xù)體類別界限處的反應(yīng)時(shí)都會(huì)顯著增大,證明了類別界限的存在,但組間差異不顯著。4.腦電實(shí)驗(yàn)證明,N2和P3的波幅受到漸變表情的強(qiáng)度影響,對(duì)微弱的(40%)情緒性表情反應(yīng)不敏感,而兩組被試都被完全的(100%)情緒表情誘發(fā)出更大的ERP成分的波幅。在不同強(qiáng)度的悲傷和憤怒表情上,抑郁組都表現(xiàn)出比控制組更大的N2和P3波幅,而對(duì)高興表情則沒有明顯地表現(xiàn)出這種差異,說明抑郁組對(duì)負(fù)性表情更加敏感。N2和P3成分的潛伏期則沒有顯著差異,說明兩組被試在加工情緒表情時(shí)發(fā)生的認(rèn)知階段是一致的。
[Abstract]:Depression is a common mental disease, with high incidence of depression. A slight change not in the process of social people's facial expressions recognition and response, this defect may be related to the social disorder of depression. Depression has obvious facial expression recognition disorder (Kohler, Hoffman, Eastman, Healey. Moberg, 2011), social defect is an important reason for the formation of depression (JoormannGotlib, 2006), and the processing of emotional facial expression may lead to impaired social defects. Study on depression group (i.e. unipolar and bipolar depression) emotional process behavior literature pointed out that compared with healthy control subjects showed emotional depression interrupt processing, by the weak performance and / or delayed response latency as the index. However, most studies focused on patients with severe depression, depression tendency With a good prediction effect on bias in response to emotional stimuli and sensitivity can not, cannot determine the defect information processing position of face processing in depression patients, the present study used the experimental materials and the research paradigm does not draw a unified results. Therefore, this experiment using gradient of the face stimulation and categorical perception paradigm, study and compared the normal population, the difference of facial expression response of College Students Depression Tendency bias and sensitivity. This study includes three experiments: depression tendency of college students gradually become biased on the response to the change of facial expression perception sensitivity. In experiment two, the experiment on the basis of pure facial depression tendency of College students the deviation in the gradient of the facial expression of the gradient response bias sensitivity of perception. Experiment three depressed people face ERP study on facial expression of categorical perception, analysis of depression group and control group in 40%, 70% and 100% of the emotional expressions of N2 and P3 wave amplitude and latency differences. The results are as follows: 1. the depression group and the control group in identifying anger - sad and happy - sad expression have shown a continuum of high the correct rate of close to the sadness prototype, but the difference between the two groups was not significant. The neutral expression morphing into continuum completely emotional expressions will anger sadness continuum separated, find and control group, depression group in identifying in anger expression time showed a higher correct rate. Two there were significant differences in expression of anger discrimination, compared with the control group, depression group of angry.2. is more sensitive in a recognition task, compared with the control group, depression group showed bias to negative stimuli response, avoid The recognition of happy expression, and in anger sadness continuum showed bias to angry reaction, but in the sensitivity of the two groups did not show differences in expression. Neutral continuum in depression group also showed the same response bias: compared with the control group, in the neutral - anger continuum, depression group more fuzzy expression recognition for anger, while in neutral - happy expression is more fuzzy continuum expression recognition is neutral, avoid recognition as happy.3. in recognition of the reaction time, whether it is the expression - expression - expression or neutral continuum continuum, close to the boundaries of the continuum category will significantly increase the reaction time, proved category boundaries exist, but no significant difference between the groups of.4. EEG experiments show that N2 and P3 amplitude is affected by intensity gradient expression, the weak (40%) is not sensitive to emotional expressions and reactions, two Subjects were completely (100%) emotion evoked a ERP component of the larger amplitude. The different intensity of sad and angry expressions, the depression group exhibited greater than the control group N2 and the amplitude of P3, and of happy expression is not evident in this difference, that is not significant differences in depression group of negative expression was more sensitive to.N2 and P3 latency, two subjects cognitive stage occurred in the processing of emotional expression is consistent.
