Upright faces are thought to be processed holistically. However, the range of views within which holistic processing occurs is unknown. Recent research by McKone (2008) suggests that holistic processing occurs for all yaw-rotated face views (i.e., full-face through to profile). Here we examined whether holistic processing occurs for pitch, as well as yaw, rotated face views. In this face recognition experiment: (i) participants made same/different judgments about two sequentially presented faces (either both upright or both inverted); (ii) the test face was pitch/yaw rotated by between 0° and 75° from the encoding face (always a full-face view). Our logic was as follows: if a particular pitch/yaw-rotated face view is being processed holistically when upright, then this processing should be disrupted by inversion. Consistent with previous research, significant face inversion effects (FIEs) were found for all yaw-rotated views. However, while FIEs were found for pitch rotations up to 45°, none were observed for 75° pitch rotations (rotated either above or below the full face). We conclude that holistic processing does not occur for all views of upright faces (e.g., not for uncommon pitch rotated views), only those that can be matched to a generic global representation of a face.
正立的面孔被认为是整体处理的。然而，整体处理发生的视角范围尚不清楚。最近 McKone（2008）的研究表明，整体处理发生在所有的偏航旋转的面部视图（即，从正面到侧面）。在这里，我们研究了对于俯仰，以及偏航，旋转的面部视图是否发生整体处理。在这个人脸识别实验中：（i）参与者对两个连续呈现的面孔（都是直立的或都是倒置的）进行相同/不同的判断；（ii）测试面孔相对于编码面孔以 0°到 75°的俯仰/偏航角度旋转（始终是正面视图）。我们的逻辑如下：如果特定的俯仰/偏航旋转的面部视图在直立时被整体处理，那么这种处理应该会被倒置破坏。与先前的研究一致，对于所有的偏航旋转视图都发现了显著的面孔反转效应（FIE）。然而，虽然在俯仰旋转 45°以内发现了 FIE，但在 75°的俯仰旋转时没有观察到（旋转超过或低于正面）。我们得出结论，整体处理不会发生在正立面孔的所有视图上（例如，对于不常见的俯仰旋转视图不会发生），而只会发生在那些可以与面孔的通用全局表示匹配的视图上。
