In our daily perception of facial expressions we depend on our ability to generalize across the various ways in which they may appear. Previous research has been inconclusive about when perceptual constancy applies. Using a psychophysical measure (Borg CR100 scale) the present study aimed to further investigate perceptual constancy of emotional facial expressions varying in size. Seventy- one (42 female) participants rated the intensity and valence of facial expressions. The results showed that the perceived intensity of the emotional facial expression was dependent on the size of the face. Furthermore, a face-gender facial expression interaction revealed perception of angry males more intense than angry females and happy females as more intense than happy males. To conclude, applying psychophysical measures the present study raises important considerations regarding constancy of the perceived intensity of emotional facial expression.
