Composite Happy Face

Caption

This composite image shows a happy face as it was originally photographed (left) and the same photo retouched to emphasize changes in color. Researchers at The Ohio State University found that people are able to correctly identify other people's feelings up to 75 percent of the time -- based solely on subtle shifts in blood flow color around the nose, eyebrows, cheeks or chin. The study demonstrates a never-before-documented connection between the central nervous system and emotional expression in the face.
