گذر از محدودیت تخصص انسان در ادراک صورت: شناسایی و ابراز عواطف و خطا به عنوان تابعی از زاویه ارائه، زمان ارائه و احساسات

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 (100 ms) 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 faces were viewed for only 100 ms, sad faces and angry faces were most often misidentified as neutral faces.
