| Abstract: | A theory relating aggression and the pitch of vocalizations [Ohala, 1983, 1984] predicts that the expression of anger in humans should have a low pitch; however, experimentally anger is found to have a high pitch. A possible resolution of this discrepancy is that there are two different prosodic expressions of anger, one with low pitch and one with high pitch. To investigate this possibility, 27 different expressions of the phrase “Don't do that” were tape-recorded. Subjects first rated how angry each utterance sounded and then categorized each utterance as expressing either frustration, threat, disgust, advice, or emotional neutrality. Some utterances were rated as angry and categorized as frustration; other utterances were also rated as angry, but categorized as threat. Frustration correlated with higher fundamental frequency (F0). Threat did not correlate with lower F0, but it correlated with lower perceived pitch. |
