虚拟现实技术的进步使得能够创建与真实环境(RES)相比具有显著高视觉保真度的虚拟环境(VE)。在这项研究中，我们使用一个高保真的VE来检验交替的VE和RE经历造成的两种影响：“上下文相关的遗忘”和“来源监控错误”。前者的效应是，在VES中学习的记忆在VES中比在RES中更容易回忆，而在RES中学习的记忆在Res中比在VES中更容易回忆。来源监控的错误是，在VES中学习的记忆很容易与在RES中学习的记忆混淆，使得辨别记忆的来源变得困难。我们假设VES的视觉保真度对这些效果负责，并使用两种类型的VE进行了实验：使用摄影测量技术创建的高保真VE和使用原始形状和材料创建的低保真VE。结果表明，高保真VE显著提高了临场感。然而，VES的视觉保真度水平对上下文相关遗忘和来源监控错误没有任何影响。值得注意的是，贝叶斯分析有力地支持了VE和RE之间的上下文相关遗忘的零结果。因此，我们认为语境依存性遗忘并不一定会发生，这将有助于基于VR的教育和培训。
Advances in virtual reality technology have enabled the creation of virtual environments (VEs) with significantly high visual fidelity when compared to real environments (REs). In this study, we use a high-fidelity VE to examine two effects caused by alternating VE and RE experiences: “context-dependent forgetting” and “source-monitoring errors.” The former effect is that memories learned in VEs are more easily recalled in VEs than in REs, whereas memories learned in REs are more easily recalled in REs than in VEs. The source-monitoring error is that memories learned in VEs are easily confused with those learned in REs, making discriminating the source of the memory difficult. We hypothesized that the visual fidelity of VEs is responsible for these effects and conducted an experiment using two types of VEs: a high-fidelity VE created using photogrammetry techniques and low-fidelity VE created with primitive shapes and materials. The results show that the high-fidelity VE significantly improved the sense of presence. However, the level of the visual fidelity of the VEs did not show any effect on context-dependent forgetting and source-monitoring errors. Notably, the null results of the context-dependent forgetting between the VE and RE were strongly supported by Bayesian analysis. Thus, we indicate that context-dependent forgetting does not necessarily occur, which will be helpful for VR-based education and training.
