Aviezer, Trope, & Todorov (2012) Had People Identify the Emotions

Aviezer, Trope, & Todorov (2012) had people identify the emotions expressed in photographs of tennis players who had either just won or lost a match. What property of combined emotion expressions (that is, whole-person expressions involving both the face and body) did they reveal?

A) At extreme intensity levels, the face reveals a lot more about the valence of an emotion expression than does the body
B) Naturalistic emotion expressions are unpredictable and difficult to recognize, so perceivers always have to rely on contextual information from the environment
C) The body is always more informative than the face in revealing whether a person is feeling positive or negative, suggesting emotion science's focus on the face is misguided
D) At extreme intensity levels, positive and negative emotions are nearly indistinguishable on the face, so cues from the body can help indicate the valence of the expresser's feelings
