New study challenges the standard scientific view of emotion perception

"Visual scenes, voices, bodies, other faces, cultural orientation, and even words shape how emotion is perceived in a face, calling into question the still-common assumption that the emotional state of a person is written on and can be read from the face like words on a page."

So does that mean that simple tests of reading facial expressions, such as Baron-Cohen and team's Reading the Mind in the Eyes Test, have limited relevance to real-world emotion perception?
