Scientific Reports發(fā)表了對“獅尾狒狒”（“舊世界”猴子的一種）快速面部模仿(RFM)的觀察結(jié)果,。這種快速的,、自動的反應(yīng)此前已在人類和猩猩中觀察到,，但沒有在非猿靈長類動物中觀察到,，而這項研究表明,，另一種靈長類動物也能夠進行這種復(fù)雜的情緒交換,。
RFM是一種快速的,、無意識的反應(yīng),，在其中一個個體模仿另一個個體的面部表情。RFM在人類中普遍存在,，它似乎反映了一個人能夠體察他人情感的能力,，而且它也在猩猩中被觀察到。鑒于RFM被認為在社會互動中所具有的重要性,，Giada Mancini,、Pier Francesco Ferrari 和 Elisabetta Palagi研究了該現(xiàn)象是否也存在于“獅尾狒狒”(Theropithecus gelada)，重點是研究在玩耍性質(zhì)的互動中所做出的面部表情,。作者發(fā)現(xiàn),，“獅尾狒狒”在玩耍時會表現(xiàn)出RFM，而RFM根據(jù)個體之間在遺傳和情緒上的親近程度的不同而變化,。最高水平的RFM和最快的反應(yīng)時間見于母親與其嬰兒之間的互動中,。
這些結(jié)果顯示,，人類RFM的演化起源有可能源自我們靈長類近親早期的母-嬰關(guān)系。（生物谷Bioon.com）

Rapid Facial Mimicry In Geladas
Giada Mancini,Pier Francesco Ferrari& Elisabetta Palagi
Rapid facial mimicry (RFM) is an automatic response, in which individuals mimic others' expressions. RFM, only demonstrated in humans and apes, is grounded in the automatic perception-action coupling of sensorimotor information occurring in the mirror neuron system. In humans, RFM seems to reflect the capacity of individuals to empathize with others. Here, we demonstrated that, during play, RFM is also present in a cercopithecoid species (Theropithecus gelada). Mother-infant play sessions were not only characterized by the highest levels of RFM, but also by the fastest responses. Our findings suggest that RFM in humans have homologous not only in apes, but also in cercopitecoids. Moreover, data point to similarities in the modality in which mother-infant synchronous behaviours are expressed among primates, suggesting a common evolutionary root in the basic elements of mother-infant affective exchanges.
