实验心理学研究通常采用的方法大大简化了认知发生的现实世界条件。这种方法在分离认知过程方面取得了成功,但不能充分捕捉感知在复杂环境中的运作方式。反过来,现实世界的环境很少提供严格的科学实验所需的访问和控制。近年来,技术的进步为这些问题提供了解决方案,通过开发负担得起的高性能虚拟现实(VR)设备。VR在心理学上的应用正在迅速增加,但在目前的VR实验中,虚拟现实角色的真实感,以及他们在视觉上代表真实人物的程度,却被捕捉得很差。在这里,我们展示了一种用户友好的方法来创建逼真的真人化身,并提供了一系列的研究来展示他们的心理特征。我们展示了熟悉的人的头像的识别精度很高(研究1),复制了在现实世界的人脸匹配中通常观察到的熟悉优势(研究2),并展示了这些头像产生的相似空间与相同面孔的真实照片密切对应(研究3)。这些研究为在虚拟现实中进行视觉感知和社会认知的心理实验开辟了道路。
Experimental psychology research typically employs methods that greatly simplify the real-world conditions within which cognition occurs. This approach has been successful for isolating cognitive processes, but cannot adequately capture how perception operates in complex environments. In turn, real-world environments rarely afford the access and control required for rigorous scientific experimentation. In recent years, technology has advanced to provide a solution to these problems, through the development of affordable high-capability virtual reality (VR) equipment. The application of VR is now increasing rapidly in psychology, but the realism of its avatars, and the extent to which they visually represent real people, is captured poorly in current VR experiments. Here, we demonstrate a user-friendly method for creating photo-realistic avatars of real people and provide a series of studies to demonstrate their psychological characteristics. We show that avatar faces of familiar people are recognised with high accuracy (Study 1), replicate the familiarity advantage typically observed in real-world face matching (Study 2), and show that these avatars produce a similarity-space that corresponds closely with real photographs of the same faces (Study 3). These studies open the way to conducting psychological experiments on visual perception and social cognition with increased realism in VR.
