戴在手腕上的振动触觉反馈被认为是一种很有前途的干预措施,可以在应激源事件中减少状态焦虑。然而,目前的工作主要集中在振动触觉刺激的持续传递上,这带来了习惯于反馈的潜在缓解效果的风险。为了减少交流恐惧,本文研究了在公共演讲任务中对振动触觉反馈的即时管理。我们评估了两种类型的振动触觉反馈传递机制,并将其与受试者之间设计的对照进行了比较-一种在随机时间点提供刺激,另一种在生理反应增强的时刻提供刺激,这由皮肤电活动的变化决定。这些干预的结果表明,在高生理唤醒期间实施的振动触觉反馈改善了干预早期的应激相关生理测量(如心率)和自我报告的应激注释,并有助于提高公共演讲任务中的声音稳定性,但这些影响随着时间的推移而减弱。在随机时间点上提供振动触觉反馈似乎会总体上恶化与压力相关的措施。
Wrist-worn vibrotactile feedback has been heralded as a promising intervention for reducing state anxiety during stressor events. However, current work has focused on the continuous delivery of the vibrotactile stimulus, which entails the risk of habituation to the potentially relieving effects of the feedback. This paper examines the just-in-time administration of vibrotactile feedback during a public speaking task in an effort to reduce communication apprehension. We evaluate two types of vibrotactile feedback delivery mechanisms compared to a control in a between-subjects design – one that delivers stimulus over random time points and one that delivers stimulus during moments of heightened physiological reactivity, as determined by changes in electrodermal activity. The results from these interventions indicate that vibrotactile feedback administered during high physiological arousal improves stress-related physiological measures (e.g., heart rate) and self-reported stress annotations early on in the intervention, and contributes to increased vocal stability during the public speaking task, but these effects diminish over time. Delivering the vibrotactile feedback over random points in time appears to worsen stress-related measures overall.
