The process by which the facial expressions send messages to the brain about the basic emotion being expressed is called ________.

A) primary emotional processing
B) internal emotion work
C) facial feedback
D) body language

The process described in the question is called facial feedback, which refers to the way that our facial expressions can influence or "feed back" into our emotional experience. Through this process, the brain receives signals from the facial muscles and uses this information to help determine the basic emotion being expressed. Choice A is close, but refers more broadly to the overall processing of emotions, while choices B and D are not accurate descriptions of the specific process being discussed.
