整体加工是面部加工的一个标志，可以通过复合面部效应来衡量：当一张脸的上半部分与一张新的下半部分对齐时，成年人很难识别出它，除非整体加工因两半部分错位而中断。就像识别面部身份一样，当面部被倒置时，整体处理会受损。为了获得一个更精确的测量方向油整体的脸处理的影响，我们管理的复合脸任务的成年人在每个七个方向。在实验I（方向随机混合）和实验2（方向受阻）中，复合面效应随旋转呈线性下降。我们的结论是，整体处理是调整到直立的脸，减少脸偏离直立，并成为微不足道的，一旦脸达到一个侧面的方向。我们提出了一个层次模型的人脸感知，在整体处理的线性下降的基础上，在其他方面的人脸感知的质的变化。
Holistic processing, a hallmark of face processing, can be measured by the composite face effect: adults have difficulty recognising the top half of a face when it is aligned with a new bottom half, unless holistic processing is disrupted by misaligning the two halves. Like the recognition of facial identity, holistic processing is impaired when faces are inverted. To obtain a more refined measure of the influence of orientation oil holistic face processing, we administered the composite face task to adults at each of seven orientations. In both experiment I (in which orientations were randomly intermixed) and experiment 2 (in which orientations were blocked), the composite face effect decreased linearly with rotation. We conclude that holistic processing is tuned to upright faces, diminishes as faces deviate from upright, and becomes insignificant once faces reach a sideways orientation. We propose a hierarchical model of face perception in which linear decreases in holistic processing underlie qualitative shifts in other aspects of face perception.
