我们经常接触到视觉场景中存在的多个对象，因此注意选择是必要的，以便有选择地对相关信息做出反应。通过在空间中定向注意力，可以基于对象所占据的位置来选择对象。在本文中，我们回顾的证据表明，注意力可以在空间中定位内源性的基础上，中央线索，预测的相关位置，或外生性，自动触发的视觉刺激（周边线索）的显着属性。基于这两种类型的线索，在定向过程中观察到的几种分离导致了这样的结论：它们并不代表触发同一种注意机制定向的两种模式，而是它们以不同的方式调节加工。我们提出了一个理论框架，根据该框架，内源性预测线索通过定向注意促进目标加工，从而放大在出席的位置处理。相反，除了注意定向，周边呈现的差异线索可能会触发额外的线索-目标事件整合和事件分离过程，以不同的方式调节加工，从而导致线索效应，专门由周边线索触发。
We are quite often exposed to multiple objects present in the visual scene, thus attentional selection is necessary in order to selectively respond to the relevant information. Objects can be selected on the basis of the location they occupy by orienting attention in space. In this paper, we review the evidence showing that attention can be oriented in space either endogenously, on the basis of central cues, predictive of the relevant location, or exogenously, automatically triggered by the salient properties of visual stimuli (peripheral cues). Several dissociations observed between orienting on the basis of the two types of cues have led to the conclusion that they do not represent just two modes of triggering the orienting of the very same attentional mechanism, but rather they modulate processing differently. We present a theoretical framework according to which endogenous predictive cues facilitate target processing by orienting attention, thus amplifying processing at the attended location. In contrast, apart from attentional orienting, peripherally presented discrepant cues might trigger additional cue-target event-integration and event-segregation processes, which modulate processing in a different way, thus leading to cueing effects that are exclusively triggered by peripheral cues.
