在两组实验中，探讨了在眉毛垂直和头部垂直运动的情况下，根据男性和女性面部照片快速进行性别分类的方法。这些研究的指导思想是，面部的性别简单提示，即眼睑和眉毛之间的垂直距离，可以支持这样的决定，男性的这个距离比女性的小，并且可以通过降低酒量、低下头、抬起眼睛对着镜头来进一步缩短。性别分类机制如何考虑姿势的变化？眉头低低的男性面孔（实验 1）可以更快、更准确地进行分类（眉毛上扬的面孔几乎没有相应的“女性化”）。低头凝视也有类似的效果，但未能以简单的方式与低头互动（实验 2）。我们得出的结论是，根据面部图像对性别进行初步分类可能不涉及将面部图像归一化为表达姿势（眉毛运动和凝视方向）的规范状态（“大头照视图”）。对于头部姿势（未正面观察脸部时特征的相对位置），不能排除归一化。讨论了这些效应的一些感知机制及其功能含义。
The speeded categorisation of gender from photographs of men's and women's faces under conditions of vertical brow and vertical head movement was explored in two sets of experiments. These studies were guided by the suggestion that a simple cue to gender in faces, the vertical distance between the eyelid and brow, could support such decisions, in men this distance is smaller than in women, and can be further reduced by lowering the brews and also by lowering the head and raising the eyes to camera. How does the gender-classification mechanism take changes in pose into account? Male faces with lowered brews (experiment 1) were more quickly and accurately categorised (there was little corresponding 'feminisation' of raised-brow faces). Lowering gaze had a similar effect, but failed to interact with head lowering in a simple manner (experiment 2). We conclude that the initial classification of gender from the facial image may not involve normalisation of the face image to a canonical state (the 'mug-shot view') for expressive pose (brow movement and direction of gaze). For head pose (relative position of the features when the face is not viewed head-on), normalisation cannot be ruled out. Some perceptual mechanisms for these effects, and their functional implications, are discussed.
