The perception and passage of time during public speaking

Several studies have shown that anxious individuals experience a slower passage of time under threat conditioning. Anxiety-evoking situations have also been proposed to elevate arousal levels, which, in turn, alter one's time percept. However, the effect of social stressors on time perception remains significantly neglected. The current research aimed to investigate the impact of anxiety levels on time estimation and passage of time judgments during public speaking in healthy adults. Participants were recruited from a pool of students that had to give a presentation as part of a university course or their teaching duties. Following the presentation, they were asked to make retrospective time estimations on the duration of the latter, as well as to provide passage of time judgments. Self-reported questionnaires related to affective states, public speaking anxiety, and performance were also administered. Analysis showed that higher levels of public speaking anxiety predicted temporal overestimation and slower "feel" duration and passage of time. Moreover, the relationship between public speaking anxiety and passage of time was mediated by participants' mood states, which remained significant after -indirectly- controlling for fear of evaluation. Overall, our observations suggest that anxiety levels during public presentation significantly predict altered perception and experience of time. The latter can be explained by the speaker's mood status. Identifying the mechanisms that modulate timing under psychological stressors could complement our understanding regarding their impact on educational and social settings, as well as set the ground towards the development of early intervention and prevention strategies for those who suffer from stress-related disorders.
