Global and Local Evaluations of Public Speaking Performance in Social Anxiety

Abstract

Differences in the relative use of global and local information (seeing the forest vs. the trees) may explain why people with social anxiety often do not benefit from corrective feedback, even though they pay close attention to details in social situations. In the current study, participants high (n = 43) or low (n = 47) in social anxiety symptoms gave a series of brief speeches, and then self-rated their speaking performance on items reflecting global and local performance indicators (self-assessment) and also received standardized performance feedback from an experimenter. Participants then completed a questionnaire asking how they thought the experimenter would rate their performance based on the feedback provided (experimenter assessment). Participants completed the self- and experimenter assessments again after 3 days, in addition to a measure of postevent processing (repetitive negative thinking) about their speech performance. Results showed that, as hypothesized, the High SA group rated their performance more negatively than the Low SA group. Moreover, the High SA group's ratings of global aspects of their performance became relatively more negative over time, compared to their ratings of local aspects and the Low SA group's ratings. As expected, postevent processing mediated the relationship between social anxiety group status and worsening global performance evaluations. These findings point to a pattern of progressively more negative global evaluations over time for persons high in social anxiety.

Research Highlights

► Individuals with social anxiety use global and local information differently in evaluating their social performance. ► Socially anxious participants' global performance ratings became more negative over time, compared to local ratings. ► Post-event processing mediated the relationship between social anxiety and worsening global performance evaluations.

Participants

A total of 48 high social anxiety (High SA) participants and 49 low social anxiety (Low SA) participants completed the study in exchange for course credit or payment. All participants completed a set of preselection measures, including the Social Interaction Anxiety Scale (SIAS) and the public-speaking item from the Social Phobia Scale (SPS) that reads, “I get tense when I speak in front of other people” (Mattick & Clarke, 1998). Those who scored less than or equal to three-quarters of a

Sample Characteristics

As determined by preselection, social anxiety groups differed on SIAS scores; High SA: M = 42.73, SD = 11.08; Low SA: M = 6.82, SD = 2.27; t(88) = 21.73, p < .001, d = 4.63. As expected, the High SA group also reported more fear of negative evaluation on the BFNE (M = 41.42, SD = 9.52) than the Low SA group (M = 30.05, SD = 8.64), t(88) = 5.94, p < .001, d = 1.27. In addition, the High SA group reported more social performance anxiety on the SPS (M = 26.35, SD = 12.58) than the Low SA group (M = 8.63, SD = 6.30), t(88) = 8.56, p < 

Discussion

This study was conducted to examine global and local evaluations of public-speaking performance in socially anxious and nonanxious individuals and to investigate how these evaluations change over time. Consistent with much previous research and our hypotheses, socially anxious individuals generally rated themselves as having performed worse on a public-speaking task than nonanxious individuals. Further, although the High SA group did not rate their global speaking performance as worse than

    Taken together, results suggest that the relationship between post-event and anticipatory processing is complex and further nuanced by level of measurement (e.g., momentary versus averaged) or assessment period (e.g., within or across days). Though participants higher in trait social anxiety symptoms reported engaging in more post-event processing on average the day following Speech 1, post-event processing was unrelated to change in performance appraisals, which contrasted with our hypotheses and the findings from Cody and Teachman (2011). Trait social anxiety symptoms were also unrelated to change in performance appraisals.

    However, this explanation is unlikely, since research indicates that objective speech performance ratings are comparable for those with and without SAD (Rapee & Lim, 1992; Voncken & Bögels, 2008). Instead, a more likely explanation is that individuals with SAD appraise their performance more negatively (and inaccurately) compared to non-clinical individuals (Cody & Teachman, 2011; Rapee & Lim, 1992), making them more inclined to ruminate afterwards, as predicted by the Clark and Wells (1995) model of social anxiety. Indeed, it has been shown that the degree of post-event rumination one week after a social event is strongly predicted by the perceived performance following the event (Abbott & Rapee, 2004).

    Participants then underwent positive CBM-I training (45 minutes long), and then after 5 minutes completed the assessment procedure (10 minutes long) as detailed above. Finally, participants completed a behavioral avoidance task (adapted from Cody & Teachman, 2011) in the form of an impromptu speech. Participants were informed that they would give a recorded speech educating their peers about recent health care reforms in this country, and that they had up to 5 minutes to speak.
