A new study has found that brain activity in response to pictures of angry or neutral faces may predict the helpfulness of cognitive behavioral therapy for social anxiety.

Researchers at the Massachusetts Institute of Technology (MIT) recorded participants' brain activity in response to seeing angry or neutral faces as well as negative or neutral scenes. People with social anxiety reacted much more strongly to the faces in general than to the scenes, but they also showed more reduced symptoms with therapy if they reacted strongly to the angry faces in particular. Their brain activity predicted the helpfulness of their therapy better than their answers did on the commonly used Liebowitz Social Anxiety Scale (LSAS).
