The article introduces an original VR-based experiment which explores context-dependent memory recall in humans. It specifically examines the recall of correct and falsely induced semantic memories. With the aid of VR head-mounted displays, 92 students of psychology were placed in a computer-generated indoor virtual environment and asked to memorize the presented lists of words. Afterwards, the participants were placed in the same indoor virtual environment or an alternative outdoor virtual environment and asked to recall the words. The number of correct and falsely induced words was then measured. On average, women recalled significantly more correct words from the list than men, regardless of the environmental context. Despite the assumptions, we did not observe a separate effect of exposure to different environments during learning and recall of material on memory performance. Likewise, we did not detect any effects of the learning context or biological sex in the case of the production of false memories. These results provide a novel insight into previous knowledge regarding the memory processes that occur in virtual environments. Although we failed to confirm the role of context in recalling learned material in general, we found a hint that this context might interact with specific memory processes of biological sexes. However, the design of this study only captured the effect of changing the environment during memory recall and did not address the role of specific context in remembering learning material. Further research is therefore needed to better investigate these phenomena and examine the role of biological sex in context-dependent memory processes.
这篇文章介绍了一项基于虚拟现实的原创实验，该实验探索了人类情境依赖记忆的召回。它特别考察了正确和错误诱导的语义记忆的召回。借助虚拟现实头戴式显示器，92 名心理学学生被置于计算机生成的室内虚拟环境中，并要求记住呈现的单词列表。之后，参与者被置于相同的室内虚拟环境或替代的室外虚拟环境中，并要求回忆单词。然后测量正确和错误诱导的单词数量。平均而言，女性从列表中回忆出的正确单词数量明显多于男性，而不论环境背景如何。尽管存在假设，但我们在学习和回忆材料时没有观察到不同环境暴露对记忆表现的单独影响。同样，我们在错误记忆的产生中也没有检测到学习环境或生物性别方面的任何影响。这些结果为我们提供了一个新的视角，了解在虚拟环境中发生的记忆过程的先前知识。尽管我们未能普遍证实环境在回忆所学材料方面的作用，但我们发现了一个暗示，即这种环境可能与生物性别的特定记忆过程相互作用。然而，这项研究的设计仅捕捉了在记忆回忆期间改变环境的效果，并未解决特定环境在记忆学习材料方面的作用。因此，需要进一步的研究来更好地调查这些现象，并研究生物性别在情境依赖记忆过程中的作用。
