When someone observes another individual suddenly shifting gaze, the observer's attention automatically and rapidly orients to the same location. Such gaze cuing of attention has properties similar to those of exogenous cuing. We investigated whether gaze cuing is also like exogenous cuing in that it is observed for both spatial and object-/head-centered frames of reference. That is, when the face that produces the gaze cue is presented on its side, tilted 90 degrees from upright, will attention be simultaneously directed to where the eyes would have been looking if the face had been presented upright and toward the actual spatial direction of gaze? It is demonstrated that gaze cues do indeed orient attention in both spatial and object-centered frames, that these effects are of similar magnitude, and that such orienting is relatively rapidly computed.
当有人观察到另一个人突然转移目光时，观察者的注意力会自动且迅速地转向同一位置。这种注意力的目光提示具有与外源性提示相似的特性。我们研究了目光提示是否也与外源性提示一样，在空间和以物体/头部为中心的参照系中都能观察到。也就是说，当产生目光提示的脸以侧面呈现，与直立状态倾斜90度时，注意力是否会同时指向如果脸呈直立状态时眼睛所看的方向以及实际的目光空间方向？结果表明，目光提示确实能在空间和以物体为中心的参照系中引导注意力，这些效应的大小相似，而且这种引导是相对快速计算出来的。
