P. Gosselin et G. Kirouac, DECODING FACIAL PROTOTYPES IN EXPRESSIVE EMOTIONAL REPERTORIES, Canadian journal of experimental psychology, 49(3), 1995, pp. 313-329
This study examined the recognition of the facial prototypes comprised
in the expressive emotional repertory proposed by Ekman and Friesen (
1978a) and by Wiggers (1982). The prototypes were shown to 74 decoders
who had to rate the intensity of the emotion or emotions being portra
yed. The results indicated that the majority of the prototypes, except
those of fear and disgust, clearly signaled the predicted emotion. Th
e various prototypes related to the same emotion were found to differ
in their signal value, some of them being better recognized and more s
pecific than others. Some prototypes of fear and disgust were found to
signal mixed rather than pure emotions. The results also revealed tha
t the level of recognition of emotional expression varies according to
the encoder which suggests that interindividual differences in facial
anatomy influence the perception of emotion.
