Virtual cognitions (VCs) are a stream of simulated thoughts people hear while emerged in a virtual environment, e.g. by hearing a simulated inner voice presented as a voice over. They can enhance people’s self-efficacy and knowledge about, for example, social interactions as previous studies have shown. Ownership and plausibility of these VCs are regarded as important for their effect, and enhancing both might, therefore, be beneficial. A potential strategy for achieving this is the synchronization of the VCs with people’s eye fixation using eye-tracking technology embedded in a head-mounted display. Hence, this paper tests this idea in the context of a pre-therapy for spider and snake phobia to examine the ability to guide people’s eye fixation. An experiment with 24 participants was conducted using a within-subjects design. Each participant was exposed to two conditions: one where the VCs were adapted to eye gaze of the participant and the other where they were not adapted, i.e. the control condition. The findings of a Bayesian analysis suggest that credibly more ownership was reported and more eye-gaze shift behaviour was observed in the eye-gaze-adapted condition than in the control condition. Compared to the alternative of no or negative mediation, the findings also give some more credibility to the hypothesis that ownership, at least partly, positively mediates the effect eye-gaze-adapted VCs have on eye-gaze shift behaviour. Only weak support was found for plausibility as a mediator. These findings help improve insight into how VCs affect people.

虚拟现实中自适应模拟内心声音对用户注视行为、所有权感知和合理性判断的影响

虚拟认知 (VC) 是人们在虚拟环境中听到的一系列模拟思想,例如通过听到作为画外音呈现的模拟内心声音。正如先前的研究表明的那样,它们可以提高人们的自我效能感和对社交互动等方面的了解。这些 VC 的所有权和合理性被认为对其效果很重要,因此增强两者可能是有益的。实现这一目标的一个潜在策略是使用嵌入在头戴式显示器中的眼动追踪技术将 VC 与人们的注视同步。因此,本文在蜘蛛和蛇恐惧症的预治疗背景下测试了这一想法,以检查引导人们注视的能力。使用受试者内设计进行了一项有 24 名参与者的实验。每个参与者都暴露在两种条件下:一种是 VC 适应了参与者的眼睛注视,另一种是它们不适应,即控制条件。贝叶斯分析的结果表明,与控制条件相比,在眼睛注视适应条件下报告了更多的所有权,并且观察到了更多的视线转移行为。与无中介或消极中介的替代方案相比,研究结果还为以下假设提供了更多可信度:所有权至少部分地正中介了适应视线的风险投资对视线转移行为的影响。作为调解人的合理性只发现了微弱的支持。这些发现有助于深入了解风险投资如何影响人们。一种是 VC 适应了参与者的眼睛注视,另一种是不适应,即控制条件。贝叶斯分析的结果表明,与控制条件相比,在眼睛注视适应条件下报告了更多的所有权,并且观察到了更多的视线转移行为。与无中介或消极中介的替代方案相比,研究结果还为以下假设提供了更多可信度:所有权至少部分地正中介了适应视线的风险投资对视线转移行为的影响。作为调解人的合理性只发现了微弱的支持。这些发现有助于深入了解风险投资如何影响人们。一种是 VC 适应了参与者的眼睛注视,另一种是不适应,即控制条件。贝叶斯分析的结果表明,与控制条件相比,在眼睛注视适应条件下报告了更多的所有权,并且观察到了更多的视线转移行为。与无中介或消极中介的替代方案相比,研究结果还为以下假设提供了更多可信度:所有权至少部分地正中介了适应视线的风险投资对视线转移行为的影响。作为调解人的合理性只发现了微弱的支持。这些发现有助于深入了解风险投资如何影响人们。贝叶斯分析的结果表明,与控制条件相比,在眼睛注视适应条件下报告了更多的所有权,并且观察到了更多的视线转移行为。与无中介或消极中介的替代方案相比,研究结果还为以下假设提供了更多可信度:所有权至少部分地正中介了适应视线的风险投资对视线转移行为的影响。作为调解人的合理性只发现了微弱的支持。这些发现有助于深入了解风险投资如何影响人们。贝叶斯分析的结果表明,与控制条件相比,在眼睛注视适应条件下报告了更多的所有权,并且观察到了更多的视线转移行为。与无中介或消极中介的替代方案相比,研究结果还为以下假设提供了更多可信度:所有权至少部分地正中介了适应视线的风险投资对视线转移行为的影响。作为调解人的合理性只发现了微弱的支持。这些发现有助于深入了解风险投资如何影响人们。正向调节眼睛注视适应的 VC 对视线转移行为的影响。作为调解人的合理性只发现了微弱的支持。这些发现有助于深入了解风险投资如何影响人们。正向调节眼睛注视适应的 VC 对视线转移行为的影响。作为调解人的合理性只发现了微弱的支持。这些发现有助于深入了解风险投资如何影响人们。
