Learning, rendered in an implicit (unconscious) or explicit (conscious) way, is a crucial part of our daily life. Different factors, like attention or motivation, influence the transformation from implicit to explicit memory. Via virtual reality a lively and engaging surrounding can be created, whereby motivational processes are assumed to be a vital part of the transition from implicit to explicit memory. In the present study, we tested the impact of an enriched virtual reality compared to two conventional, non-enriched 2D-computer-screen based tasks on implicit to explicit memory transformation, using an audio-visual sequential association task. We hypothesized, that the immersive nature of the VR surrounding enhances the transfer from implicit to explicit memory. Notably, the overall amount of learned sequence pairs were not significantly different between experimental groups, but the degree of awareness was affected by the different settings. However, we observed an increased level of explicitly remembered pairs within the VR group compared to two screen-based groups. This finding clearly demonstrates that a near-natural experimental setting affects the transformation process from implicit to explicit memory.
学习,无论是内隐(无意识)的还是外显(有意识)的,都是我们日常生活的重要组成部分。不同的因素,如注意力或动机,影响着从内隐记忆到外显记忆的转化。通过虚拟现实可以创造一个生动和吸引人的环境,在这个环境中,动机过程被认为是从内隐记忆到外显记忆转化的重要组成部分。在本研究中,我们使用视听序列联想任务,测试了与两种传统的非丰富 2D 计算机屏幕任务相比,丰富的虚拟现实对从内隐到外显记忆转化的影响。我们假设,虚拟现实环境的沉浸式特性增强了从内隐到外显记忆的转移。值得注意的是,实验组之间学习的序列对的总数没有显著差异,但不同设置会影响意识程度。然而,我们观察到,与基于屏幕的两个组相比,虚拟现实组中明显记住的序列对的数量有所增加。这一发现清楚地表明,接近自然的实验环境会影响从内隐到外显记忆的转化过程。
