【摘要】：在現(xiàn)實(shí)生活中,人們?yōu)榱诉_(dá)到自己的目的往往會(huì)需要實(shí)施欺騙,這就需要人們對自身真實(shí)的情感和感受進(jìn)行壓抑和隱藏。然而,這些被壓抑和隱藏的真實(shí)感受有時(shí)會(huì)以一種非�？焖俚拿娌勘砬榈男问奖槐磉_(dá)出來,這種表情被稱之為微表情。由于表達(dá)了人的真實(shí)意圖,微表情成為了檢測謊言和危險(xiǎn)意圖的有力行為線索。然而,微表情的表達(dá)速度很快,人很難準(zhǔn)確識(shí)別微表情。已有的研究表明在普通表情識(shí)別過程中面部反饋信息是進(jìn)行表情識(shí)別一種有效的內(nèi)在線索。作為人類面部表情的一種特殊形式,研究者目前并不了解面部反饋在微表情識(shí)別過程中的作用。對這一問題的回答,將加深研究者對微表情識(shí)別過程的理解,為微表情在臨床、司法及反恐等領(lǐng)域的應(yīng)用提供理論基礎(chǔ)。 本研究探討面部反饋在微表情識(shí)別中的作用,共包括兩個(gè)實(shí)驗(yàn)。在實(shí)驗(yàn)1中,研究者通過增強(qiáng)面部肌肉運(yùn)動(dòng)阻抗的方式,研究了增強(qiáng)面部反饋對微表情識(shí)別過程的影響。在實(shí)驗(yàn)2中,研究者通過抑制嘴部的面部肌肉運(yùn)動(dòng)的方式,研究了抑制面部反饋對微表情識(shí)別過程的影響。 研究結(jié)果顯示,增強(qiáng)面部反饋能提高被試對悲傷的微表情以及短持續(xù)時(shí)間條件下(50ms)的快樂的微表情的識(shí)別準(zhǔn)確率,但不能提高被試對驚訝、憤怒、厭惡和恐懼的微表情的識(shí)別準(zhǔn)確率。除此之外,研究結(jié)果還表明,抑制面部反饋降低了被試對驚訝的微表情以及中等持續(xù)時(shí)間條件下(150ms)的厭惡的微表情的識(shí)別準(zhǔn)確率,但不影響對悲傷、憤怒、恐懼、快樂的微表情的識(shí)別準(zhǔn)確率。這些研究結(jié)果部分支持了情緒知覺的仿真模型。這提示,在微表情識(shí)別過程中,人會(huì)自發(fā)地對知覺到的微表情進(jìn)行模仿,并能利用模仿得到的面部反饋信息來幫助進(jìn)行微表情識(shí)別。這一過程與人類識(shí)別普通表情的過程類似,提示微表情與普通表情可能具有相同的識(shí)別機(jī)制。 本研究深化了研究者對微表情識(shí)別過程及其機(jī)制的研究,為微表情研究在實(shí)踐領(lǐng)域的應(yīng)用奠定了理論基礎(chǔ)。
[Abstract]:In real life, people often need to cheat in order to achieve their own purpose, which requires people to suppress and hide their true feelings and feelings. These repressed and hidden feelings are sometimes expressed in the form of a very fast facial expression, which is called a microemoji. Microexpressions become powerful behavioral cues for detecting lies and dangerous intentions. However, microexpressions express quickly, It is very difficult for people to recognize microexpressions accurately. Previous studies have shown that facial feedback is an effective internal clue for facial expression recognition, which is a special form of human facial expression. Researchers do not understand the role of facial feedback in the process of microfacial expression recognition. The answer to this question will deepen researchers' understanding of the process of microfacial expression recognition. Judicial and anti-terrorism applications provide a theoretical basis. This study explored the role of facial feedback in microfacial expression recognition, including two experiments. In experiment 1, the researchers enhanced the movement impedance of facial muscles. The effect of enhanced facial feedback on the process of microfacial expression recognition was studied. In experiment 2, the effect of facial feedback inhibition on the process of microfacial expression recognition was studied by inhibiting facial muscle movement in the mouth. The results showed that increased facial feedback increased the recognition accuracy of sad microexpressions and happy microexpressions in a short duration of time, but did not improve the participants' anger and surprise. In addition, the results of the study showed that inhibition of facial feedback reduced the recognition accuracy of subjects for surprised microexpressions and disgust at medium duration (150 Ms). But it does not affect the accuracy of recognition of microexpressions of sadness, anger, fear, happiness. These results partially support the simulation model of emotional perception. This suggests that in the process of microfacial expression recognition, People spontaneously mimic perceived microexpressions, and can use the imitated facial feedback to help them recognize microexpressions. This process is similar to the human process of recognizing ordinary expressions. It suggests that microfacial expression may have the same recognition mechanism as ordinary expression. This study deepens the research on the process and mechanism of microfacial expression recognition, and lays a theoretical foundation for the application of microfacial expression research in the field of practice.
