High-level adaptation effects reveal important features of the neural coding of objects and faces. View-adaptation in particular is a highly useful means of characterizing how depth rotation of the face is represented and therefore, how view-invariant recognition of the face may be achieved. In the present study, we used view adaptation to determine the extent to which depth rotations of a face are represented in an image-based or object-based manner. Specifically, we dissociated object-based axes from image-based axes via a 90° planar rotation of the adapting face and observed that participants' responses pre- and post-adaptation are most consistent with an image-based representation of depth rotations of the face. We discuss our data in the context of previous results describing the impact of planar rotation on related aspects of face perception.
高级适应效应揭示了物体和面部神经编码的重要特征。特别是视图适应，是一种非常有用的手段，可用于表征面部深度旋转是如何被表征的，因此也可用于了解如何实现面部的视图不变识别。在本研究中，我们使用视图适应来确定面部深度旋转在基于图像或基于物体的方式中被表征的程度。具体而言，我们通过使适应面部进行90°平面旋转，将基于物体的轴与基于图像的轴区分开来，并观察到参与者在适应前后的反应与基于图像的面部深度旋转表征最为一致。我们在先前描述平面旋转对面部感知相关方面影响的结果背景下讨论我们的数据。
