【摘要】：情緒面孔是最常見(jiàn)的視覺(jué)刺激,通常傳遞著非常重要的社會(huì)信息,這些信息有助于人們?cè)谏鐣?huì)交往中較快地推測(cè)他人的行為意圖。面孔情緒變化是指同一個(gè)人的面部表情從一種情緒變化到另一種情緒,比如,從中性情緒變化到生氣情緒。在面孔情緒變化的研究中,大量的研究考察了個(gè)體對(duì)中-生面孔情緒變化的識(shí)別,但對(duì)生-中面孔情緒變化(從生氣表情變化到中性表情)的研究較少。社交焦慮障礙也被稱為社交恐懼癥,是指?jìng)�(gè)體在社交情境或人際交流中感到持久的害怕和不安,并主動(dòng)采取回避的一種社交行為。目前已有大量的研究考察了社交焦慮個(gè)體對(duì)靜態(tài)情緒面孔的識(shí)別,但是對(duì)社交焦慮個(gè)體識(shí)別面孔情緒變化的研究還相對(duì)較少。因此,本研究運(yùn)用ERP技術(shù)首先考察個(gè)體對(duì)中-生和生-中面孔情緒變化的識(shí)別,然后在此基礎(chǔ)之上考察社交焦慮個(gè)體對(duì)以上兩種基本面孔情緒變化的識(shí)別。當(dāng)前研究的意義不僅有助于研究者從新的視角考察個(gè)體對(duì)面孔情緒變化的加工,同時(shí)有助于進(jìn)一步明晰高社交焦慮個(gè)體的認(rèn)知加工過(guò)程和發(fā)病機(jī)制,并為社交焦慮的干預(yù)工作提供直接的理論依據(jù)。當(dāng)前研究的實(shí)驗(yàn)材料包括8張房屋圖片和78段面孔情緒變化視頻,其中每種情緒變化類型各26段視頻,男女各一半。實(shí)驗(yàn)采用了S1-S2范式,實(shí)驗(yàn)任務(wù)是讓被試觀看三種情緒變化的視頻并判斷前后兩段視頻中的人是否是同一個(gè)人。實(shí)驗(yàn)一以25名大學(xué)生被試為研究對(duì)象,考察這些被試對(duì)中-生和生-中面孔情緒變化的識(shí)別,而實(shí)驗(yàn)二以13名高和14名低社交焦慮被試為研究被試,探究他們對(duì)不同類型(中-生和生-中面孔情緒變化)面孔情緒變化的識(shí)別。研究得出三個(gè)主要結(jié)論:(1)高社交焦慮個(gè)體在識(shí)別生-中面孔情緒變化時(shí)所誘發(fā)的P200波幅顯著小于其在識(shí)別情緒不變化時(shí)所誘發(fā)的波幅,而低社交焦慮個(gè)體卻未表現(xiàn)出這種差異,這一結(jié)果表明高社交焦慮個(gè)體在識(shí)別面孔情緒變化時(shí)表現(xiàn)出加工缺陷。(2)高低社交焦慮被試在識(shí)別生-中面孔情緒變化時(shí)所誘發(fā)的N170波幅顯著大于其對(duì)中-生情緒變化的識(shí)別,這表明高低社交焦慮被試在識(shí)別生-中這種情緒變化時(shí),更傾向采用特征加工的方式。(3)個(gè)體在生-中面孔情緒變化條件下的反應(yīng)時(shí)顯著快于中-生面孔情緒變化。此外,個(gè)體在識(shí)別生-中面孔情緒變化條件的P100潛伏期顯著的短于中-生的情緒變化。這些結(jié)果表明個(gè)體可以更準(zhǔn)確、更迅速地識(shí)別生-中情緒變化,對(duì)其表現(xiàn)出識(shí)別偏向。
[Abstract]:Emotional faces are the most common visual stimuli that usually convey very important social messages. This information helps people to speculate more quickly on the behavioral intentions of others in social interactions. Facial emotional change refers to the change of facial expressions from one emotion to another, for example, From neutral emotion to angry emotion. In the study of facial emotion change, a large number of studies have examined the individual recognition of middle-born facial emotion change, But less research has been done on the mood changes in the libido to neutral faces. Social anxiety disorder, also known as social phobia, refers to the persistent fear and uneasiness of an individual in a social situation or interpersonal communication. At present, a large number of studies have examined the recognition of static emotional faces by individuals with social anxiety, but there are relatively few studies on the recognition of emotional changes of faces by individuals with social anxiety. In this study, ERP technique was used to investigate the recognition of facial emotion changes in middle and middle faces. On the basis of this, we investigate the recognition of the two basic facial emotion changes by the individuals with social anxiety. The significance of the current research is not only helpful for the researchers to examine the processing of the changes in the facial emotions from a new perspective. It also helps to further clarify the cognitive process and pathogenesis of individuals with high social anxiety. The current research materials include 8 pictures of houses and 78 videos of facial mood changes, including 26 videos for each type of mood change. The experiment used S1-S2 paradigm. The task of the experiment was to ask the subjects to watch three kinds of video of mood changes and determine whether the person in the two videos was the same person. In experiment one, 25 college students were selected as the subjects. These subjects were investigated to identify the emotional changes of middle and middle faces. In experiment two, 13 subjects with high social anxiety and 14 subjects with low social anxiety were selected as subjects. This study explored their recognition of different types of facial mood changes (middle-born and born-middle-face mood changes). Three main conclusions were drawn: 1) the P200 induced by high social anxiety individuals in identifying the birth-middle facial mood changes. The amplitude is significantly smaller than the amplitude induced by the identification of unchanged emotions, Individuals with low social anxiety did not, however, show this difference. The results showed that the individuals with high social anxiety showed processing defects in identifying the change of facial emotion.) the amplitude of N170 induced by high and low social anxiety was significantly larger than that of recognition of the change of emotion in middle and middle face. This indicates that the subjects with high and low social anxiety tend to adopt the method of feature processing when they recognize the emotional changes in life and middle face.) the response time of individuals under the condition of changing emotion of life and middle faces is significantly faster than that of middle faces. In addition, the change of emotion of middle and middle faces is much faster than that of high and low social anxiety. The P100 incubation period of the individual in the condition of recognizing the change of the emotion between the born and the middle face is significantly shorter than that in the middle one. These results show that the individual can recognize the change of the emotion more accurately and rapidly and show the recognition bias towards it.
