Audience‐perceived anxiety patterns of public speakers

Abstract

Gray's neurological theory of anxiety (1982, 1990; Gray & McNaughton, 2000) predicts that state anxiety will decrease with continuous exposure to a fear arousing stimulus. Previous studies of psychological and physiological state anxiety patterns during public speaking have reported a pattern of progressively decreasing anxiety levels consistent with this phenomenon, known as habituation. In the current report, the extent to which the state anxiety behaviors of speakers conform to the habituation pattern is examined. In the first of two studies, 30 novice speakers presented informative speeches to audiences of 18 to 20 fellow students. These speeches were videotaped and replayed in their entirety for observers (N=30) who rated the severity of each performer's speech anxiety behaviors. In the second study, each videotaped presentation was divided into one‐minute segments and presented in random order to a new set of observers (N=25). Procedures in the second study were designed to control for rater expectations that state anxiety would decline over time. Overall, behavioral measures of public speaking state anxiety displayed a continually declining pattern associated with habituation.
