Multichannel Communication: The Impact of the Paralinguistic Channel on Facial Expression of Emotion.
Brideau, Linda B.; Allen, Vernon L.
A study was undertaken to examine the impact of the paralinguistic channel on the ability to encode facial expressions of emotion. The first set of subjects, 19 encoders, were asked to encode facial expressions for five emotions (fear, sadness, anger, happiness, and disgust). The emotions were produced in three encoding conditions: facial channel alone, facial channel plus paralinguistics, and facial channel plus mouthing. The second set of subjects, 60 decoders, were shown silent videotapes of encoders' facial expressions. Decoders' accuracy in detecting the intended emotions was used as an index of communication accuracy. The results indicated that access to the paralinguistic channel had both facilitative and inhibitory effects on accuracy of communication by the facial channel. The direction of the effect was dependent on the emotion encoded. In addition, it was found that the impact of paralinguistics on the facial channel was due to the systematic face movements concomitant to talking rather than to the production of appropriate vocal intonations. It was suggested that facial movements inhibited emotions expressed in the upper half of the face, but facilitated emotions expressed in the lower half of the face. (Author/RL)
