随着虚拟现实技术在日常生活中的广泛使用和应用，动态虚拟刺激越来越受到认知研究的关注。它们允许控制诸如凝视、表情和运动等特征，这可能有助于克服使用静态或控制不佳的真实刺激的局限性。然而，在使用虚拟刺激时，人们必须小心避免恐怖谷效应——现实刺激可能被认为是怪异的，并引起厌恶反应。同时，重要的是要确定对虚拟刺激的反应是否反映了对真实同物描述的反应。在当前的研究中，我们描述了一种具有逼真特征的非人类灵长类动物的新化身——“灵长类”的发展。作为验证的第一步，我们评估了猴子对这个化身图像的反应，并将其与真实的猴子图像和不真实的化身图像进行了比较。我们还比较了原始图像与这些图像的混乱和混淆版本之间的反应。我们测量了6只自由运动的长尾猕猴（Macaca fascularis）对图像的注视时间和3只恒河猕猴（Macaca mulatta）的眼动探索行为。两组人都表现出对原始图像的明显关注，而不是对混乱或混淆的图像。此外，我们还评估了逼真的虚拟形象是否会通过减少观看时间而产生恐怖谷效应，结果发现，在两组猴子中，猴子都无法区分真实、逼真或不真实的图像。这些结果为我们的虚拟形象在社会认知研究中的进一步发展提供了支持，更广泛地用于非人类灵长类动物的虚拟刺激认知研究。未来的研究需要阐明猕猴恐怖谷效应的不一致发现的来源，以阐明这种机制在人类中的根源。
Following the expanding use and applications of virtual reality in every-day life, dynamic virtual stimuli are of increasing interest in cognitive studies. They allow for control of features such as gaze, expression and movement, which may help to overcome limitations of using either static or poorly controlled real stimuli. In using virtual stimuli however, one must be careful to avoid the uncanny valley effect - where realistic stimuli can be perceived as eerie, and induce an aversion response. At the same time, it is important to establish whether responses to virtual stimuli mirror responses to depictions of a real conspecific. In the current study, we describe the development of a new avatar with realistic features for nonhuman primates, the ‘primatar’. As a first step towards validation, we assessed how monkeys respond to images of this avatar compared to images of real monkeys, and an unrealistic avatar. We also compared responses between original images and scrambled as well as obfuscated versions of these images. We measured looking time to images in six free moving long-tailed macaques (Macaca fascicularis) and eye movement exploration behaviour in three rhesus macaques (Macaca mulatta). Both groups showed more of such signs of overt attention to original images than scrambled or obfuscated images. In addition, we assessed whether the realistic avatar created an uncanny valley effect through decreased looking time, finding that in both groups, monkeys did not differentiate between real, realistic or unrealistic images. These results provide support for further development of our avatar for use in social cognition studies, and more generally for cognitive research with virtual stimuli in nonhuman primates. Future research needs to shed light on the source of the inconsistent findings for the uncanny valley effect in macaques, to elucidate the roots of this mechanism in humans.
