心理学研究的一个重要问题是，在实验室中进行的实验或基于这些实验的理论如何与人类在日常生活中的表现相关联。沉浸式虚拟现实（VR）允许在增加生态有效性的情况下控制刺激和条件。本研究的目标是完成传统范式的转移，评估注意力和分心沉浸式VR。为了进一步提高生态效度，我们探索了注意力的影响，日常的物体作为刺激，而不是简单的字母。参与者在虚拟厨房的台面上的干扰物中寻找目标。目标干扰辨别力是不同的，并显示伴随着一个周边侧翼，是一致或不一致的目标。反应时间较慢时，目标干扰辨别力低，当侧翼不一致。在第二个实验中，刺激以二维形式呈现在计算机屏幕上。该研究成功地将传统的范式和操作转化为沉浸式VR，并为未来VR中的注意力和分心研究奠定了基础。此外，我们提供了一个大纲，未来的研究，应使用VR的功能，在传统的实验室研究中不可用。
An important issue of psychological research is how experiments conducted in the laboratory or theories based on such experiments relate to human performance in daily life. Immersive virtual reality (VR) allows control over stimuli and conditions at increased ecological validity. The goal of the present study was to accomplish a transfer of traditional paradigms that assess attention and distraction to immersive VR. To further increase ecological validity we explored attentional effects with daily objects as stimuli instead of simple letters. Participants searched for a target among distractors on the countertop of a virtual kitchen. Target–distractor discriminability was varied and the displays were accompanied by a peripheral flanker that was congruent or incongruent to the target. Reaction time was slower when target–distractor discriminability was low and when flankers were incongruent. The results were replicated in a second experiment in which stimuli were presented on a computer screen in two dimensions. The study demonstrates the successful translation of traditional paradigms and manipulations into immersive VR and lays a foundation for future research on attention and distraction in VR. Further, we provide an outline for future studies that should use features of VR that are not available in traditional laboratory research.
