Expressing Emotion

We communicate emotion nonverbally through affect displays—intentional or unintentional nonverbal behaviors that display actual or feigned emotions (Burgoon et al., 1996). In everyday interactions, affect displays are presented primarily through the face and voice. Intentional use of the face to communicate emotion begins during late infancy, when babies learn to facially communicate anger and happiness to get what they want (Burgoon et al., 1996). Unintentional affect displays begin even earlier. Infants in the first few weeks of life instinctively and reflexively display facial expressions of distress, disgust, and interest. As adults, we communicate hundreds, if not thousands, of real and faked emotional states with our faces.

People also use vocalics to convey emotions. Consider how you communicate love through your voice. What changes do you make in pitch, tone, volume, and speech rate? How does your “loving” voice differ from your “angry” voice? Most people express emotions such as grief and love through lowered vocal pitch, and hostile emotions such as anger and contempt through loudness (Costanzo, Markel, & Costanzo, 1969). Pitch conveys emotion so powerfully that the source of the sound (human voice or other) is irrelevant, and words aren’t necessary. Researcher Klaus Scherer (1974) mimicked voice patterns on a music synthesizer and had listeners judge the emotion conveyed. Participants strongly associated high pitch with emotions such as anger, fear, and surprise, and they linked low pitch with pleasantness, boredom, and sadness.
