当我们注视某人时，我们会结合联合收割机关于他们头部朝向和眼睛偏离的信息来判断他们的注视方向。然而，当我们不直接看人，而是用我们的周边视觉时，这些联合收割机是如何结合的，这一点仍然是未知的。鉴于周边视觉有助于引导未来的注意力，了解我们如何感知他人的目光是决定他们未来行动的关键。为了检验这一点，我们要求参与者对头部转向不同方向的面部进行注视方向分类，并使用中央视觉或周边视觉进行观察。我们报告说，头部方向的权重增加在周边，其中面向前方的头部被归类为“直接”在更广泛的眼睛偏差比中央时。当周边的头部转动，“直接”的反应的数量下降，所有的目光偏差，没有一致的左，右的反应向头部旋转。对于中央呈现的头部，头部方向通常会排斥感知到的注视方向，我们发现反应没有一致的变化，这表明这种影响在周边减少。这不仅仅是外围空间分辨率较差的结果，其他影响，如拥挤和注视或头部方向的先验，可能也起作用。
When looking at someone, we combine information about their head orientation and eye deviation to judge their direction of gaze. What remains unknown, however, is how these cues combine when we are not looking directly at the person, but rather are using our peripheral vision. Given that peripheral vision helps direct future attention, understanding how we perceive other people's gaze is key to determining their future actions. To examine this, we asked participants to categorize gaze direction in faces whose heads were turned in different directions, and which were viewed using either central or peripheral vision. We report that the weight given to head orientation increases in the periphery, in which forward-facing heads were categorized as "direct" over a wider range of eye deviations than when viewed centrally. When peripheral heads were turned, the number of "direct" responses fell for all gaze deviations with no consistent shift in left-right responses toward the head rotation. For centrally presented heads, head orientation typically repulsed the perceived direction of gaze, and our finding of no consistent shift in responses indicates that such effects are reduced in the periphery. This is not simply the result of poorer spatial resolution in the periphery-other influences, such as crowding and priors for gaze or head direction, may play a role.
