公众演讲是给人留下好印象、有效交流思想和影响他人的一项至关重要的技能。然而，公共演讲焦虑(PSA)被列为最大的社交恐惧症。可穿戴设备和无处不在的虚拟现实(VR)接口的最新进步可以帮助测量和减少PSA。这项研究通过与个体生理和声学特征相关的生物行为标记物来量化PSA。通过自我报告和生物行为指标衡量虚拟现实(VR)训练对缓解PSA的效果。心理(如一般特质焦虑、个性)和人口统计(如年龄、性别、最高学历、母语)特质被视为生物行为指标与PSA之间的调节因素，以及衡量VR在缓解PSA方面的有效性的调节因素。这些衡量标准也被用作在基于群体的PSA模型中对参与者进行分层的分组标准。结果表明，这些性状对用所提出的基于组的模型来建模PSA具有重要意义，该模型的Spearman相关系数为0.55(<；inline-Formal>；<；Tex-Math notation=“LaTeX”>；$p<；0.05$<；/tex-math>；<；alternatives>；<；mml:math>；<；mml:mrow>；<；mml:mi>；p<；/mml:mi>；<；mml:mo>；<；<；/mml:mo>；<；mml:mn>；0<；/mml:mn>；<；mml:mo>；.<；/mml:mo>；<；mml:mn>；05<；/mml:mn>；<；/mml:mrow>；<；/mml:math>；<；inline-graphic xlink:href=“chaspari-ieq1-3048299.gif”/>；<；/alternatives>；<；/inline-formula>；)在实际结果和预测结果之间。结果进一步表明，系统地暴露在虚拟现实中的公开演讲可以在自我报告(<；内嵌公式；<；Tex-Math notation=“LaTeX”>；$p<；0.05$<；/tex-math>；<；alternatives>；<；mml:math>；<；mml:mrow>；<；mml:mi>；p<；/mml:mi>；<；mml:mo>；<；<；/mml:mo>；<；)方面缓解PSAMml:mn>；0<；/mml:mn>；<；mml:mo>；.<；/mml:mo>；<；mml:mn>；05<；/mml:mn>；<；/mml:mrow>；<；/mml:math>；<；inline-graphic xlink:href=“chaspari-ieq2-3048299.gif”/>；<；/alternatives>；<；/inline-formula>；)和生理学(<；内联公式>；<；TeX-MATH notation=“LaTeX”>；$p<；0.05$<；/tex-math>；<；alternatives>；<；mml:math>；<；mml:mrow>；<；mml:mi>；p<；/mml:mi>；<；mml:mo>；<；<；/mml:mo>；<；mml:mn>；0<；/mml:mn>；<；mml:mo>；.<；/mml:mo>；<；mml:mn>；05<；/mml:mn>；<；/mml:mrow>；<；/mml:math>；<；inline-graphic xlink:href=“chaspari-ieq3-3048299.gif”/>；<；/alternatives>；<；/inline-formula>；)指数。这项研究的发现将使研究者能够更好地了解PSA的前因和原因，并为PSA干预的个性化自适应反馈奠定基础。
Public speaking is a vital skill for making good impressions, effectively exchanging ideas, and influencing others. Yet, public speaking anxiety (PSA) ranks as a top social phobia. Recent advancements in wearable devices and ubiquitous virtual reality (VR) interfaces can help measure and mitigate PSA. This research quantifies PSA through bio-behavioral markers related to individuals’ physiological and acoustic characteristics. The effect of virtual reality (VR) training on alleviating PSA is measured through self-reported and bio-behavioral indices. Psychological (e.g., general trait anxiety, personality) and demographic (e.g., age, gender, highest education, native language) traits are examined as moderating factors between bio-behavioral indices and PSA, as well as moderating factors for measuring the VR effectiveness in mitigating PSA. These measures are also used as clustering criteria for stratifying participants in group-based models of PSA. Results indicate the significance of such traits to modeling PSA with the proposed group-based models yielding Spearman’s correlation of 0.55 (<inline-formula><tex-math notation="LaTeX">$p<0.05$</tex-math><alternatives><mml:math><mml:mrow><mml:mi>p</mml:mi><mml:mo><</mml:mo><mml:mn>0</mml:mn><mml:mo>.</mml:mo><mml:mn>05</mml:mn></mml:mrow></mml:math><inline-graphic xlink:href="chaspari-ieq1-3048299.gif"/></alternatives></inline-formula>) between the actual and predicted outcome. Results further demonstrate that systematic exposure to public speaking in VR can alleviate PSA in terms of both self-reported (<inline-formula><tex-math notation="LaTeX">$p<0.05$</tex-math><alternatives><mml:math><mml:mrow><mml:mi>p</mml:mi><mml:mo><</mml:mo><mml:mn>0</mml:mn><mml:mo>.</mml:mo><mml:mn>05</mml:mn></mml:mrow></mml:math><inline-graphic xlink:href="chaspari-ieq2-3048299.gif"/></alternatives></inline-formula>) and physiological (<inline-formula><tex-math notation="LaTeX">$p<0.05$</tex-math><alternatives><mml:math><mml:mrow><mml:mi>p</mml:mi><mml:mo><</mml:mo><mml:mn>0</mml:mn><mml:mo>.</mml:mo><mml:mn>05</mml:mn></mml:mrow></mml:math><inline-graphic xlink:href="chaspari-ieq3-3048299.gif"/></alternatives></inline-formula>) indices. Findings from this study will enable researchers to better understand antecedents and causes of PSA and lay the foundation for personalized adaptive feedback for PSA interventions.
