據(jù)2月27日的《科學(xué)》雜志報道說，當(dāng)另外一個人的行為給你留下“口中一種不好的味道”,，你是否想到它所揭示的是遠(yuǎn)比一個生動的比喻要更多的內(nèi)涵？一項對表達(dá)厭惡時面部肌肉的新的研究表明,，這一表達(dá)道德判斷的習(xí)語可能有著深層的生物學(xué)根源,。
根據(jù)Hanah Chapman及其同事的實驗披露，一種味道不佳的飲料,、一張令人厭惡的照片以及在游戲中遭遇的不公平對待等都會通過提唇肌而使人的上唇翹起及鼻子皺縮,。研究人員說，這一研究提供了某些第一次提出的直接證據(jù),，即人類的道德系統(tǒng)至少有部分是建立在更為古老的進(jìn)化適應(yīng)基礎(chǔ)之上的,。Paul Rosin、Jonathan Haidt和 Katrina Fincher在一篇相關(guān)的Perspective 中對這些發(fā)現(xiàn)進(jìn)行了討論,。（生物谷Bioon.com）

In Bad Taste: Evidence for the Oral Origins of Moral Disgust
H. A. Chapman,1* D. A. Kim,1 J. M. Susskind,1 A. K. Anderson1,2*
In common parlance, moral transgressions "leave a bad taste in the mouth." This metaphor implies a link between moral disgust and more primitive forms of disgust related to toxicity and disease, yet convincing evidence for this relationship is still lacking. We tested directly the primitive oral origins of moral disgust by searching for similarity in the facial motor activity evoked by gustatory distaste (elicited by unpleasant tastes), basic disgust (elicited by photographs of contaminants), and moral disgust (elicited by unfair treatment in an economic game). We found that all three states evoked activation of the levator labii muscle region of the face, characteristic of an oralnasal rejection response. These results suggest that immorality elicits the same disgust as disease vectors and bad tastes.
