The facial feedback hypothesis, rooted in the conjectures of Charles Darwin and William James, is that one's facial expression directly affects their emotional experience. . Specifically, physiological activation of the facial regions associated with certain emotions holds a direct effect on the elicitation of such emotional states, and the lack of or inhibition of facial activation will ...
The development of FACS tools for different species allows the objective and anatomical study of facial expressions in communicative and emotional contexts. Furthermore, a cross-species analysis of facial expressions can help to answer interesting questions, such as which emotions are uniquely human. [21]
The second study dealt with facial expressions (shown in black-and-white photographs) and vocal tone (as heard in a tape recording) and found that the relative contributions of the two communication channels had a ratio of 3:2. Mehrabian combined the results of these two studies to derive the ratio 7:38:55 for the relative importance of words ...

For example, it presents communication as a one-way process and not as a dynamic interaction of messages going back and forth ...
