Attentional consequences of (i) mere onset of a peripheral visual cue, and (ii) encoding spatially predictive, landmark features of that cue were studied in two experiments. Target location was associated with landmark features of peripheral cues. Cue onset elicited both attention capture (Experiment Two) and inhibition of return (Experiment One) effects. In both experiments, attentional effects of landmark features of the cues were observed early in practice, and diminished with time on task. Contrary to hypotheses based on models that liken attention to a moving spotlight or zoom lens, in both experiments attentional effects of landmark features were confined to the location where the cue was presented. To explain this, we enlist the concept of attentional priority maps, and propose that visual encoding causes attentional priorities to be updated via alternative input routes and mechanisms. We suggest that onset cueing effects are associated with retinotectal ‘spatial indexing’, which registers the location, but not the attributes of new stimuli, while landmark cueing effects are associated with interaction between spatial indexing and dorsal stream visual processing of attentionally relevant landmark features.

(i)仅仅是外围视觉线索的开始，以及 (ii) 编码空间预测性地标特征的注意后果在两个实验中研究了那个线索。目标位置与外围线索的标志性特征相关。提示开始引起注意捕获（实验二）和返回抑制（实验一）效果。在这两个实验中，线索的标志性特征的注意力效应在实践的早期就被观察到，并随着任务的时间而减弱。与基于将注意力比作移动聚光灯或变焦镜头的模型的假设相反，在两个实验中，地标特征的注意力效应都局限于提示出现的位置。为了解释这一点，我们引入了注意力优先级图的概念，并提出视觉编码导致注意力优先级通过替代输入路径和机制进行更新。
