Past research results suggest that reliable identification of emotions conveyed by facial expressions can be made
either when faces are: (1) briefly glimpsed, or (2) viewed in profile. Of interest was whether such effects would
persist when perceivers encountered both manipulations, briefly (100ms) viewing 90-degree profile faces. Our
results show that expertise in emotion perception has limits: Identification accuracy of emotions conveyed by
facial expressions was poor when 90-degree profile views of faces were presented for only 100 ms, especially
for the emotions of sadness and anger. Our results also suggest that: (1) overall, observers can more accurately
perceive happiness in faces than they could perceive negative emotions, and (2) in relatively easy viewing
conditions, identification of faces displaying sadness and anger were most often confused, but when 90-degree
profile faceswere viewed for only 100ms, sad faces and angry facesweremost often misidentified as neutral faces.
