我们的视觉系统对环境中的噪音高度敏感。在一个人以前的经验中很重要的位置通常在搜索过程中优先考虑，即使观察者可能没有意识到学习。在这项研究中，我们通过对目标空间概率的偶然学习来描述空间注意力的引导，并考察了内源性提示和概率提示之间的相互作用。参与者在干扰物（L）中寻找目标（T）。目标通常位于屏幕的一个区域而不是其他区域。我们发现当目标出现在高频区域而不是低频区域时，搜索RT更快。当显示器上有更多的项目时，这种差异会增加，这表明概率线索引导空间注意力。额外的数据表明，就其本身而言，概率线索和内源性线索（例如，预测目标位置的中心箭头）在引导注意力方面同样有效。然而，当两种线索同时出现时，概率线索在很大程度上被消除了。因此，虽然附带学习和内源性线索都能有效地引导注意，但内源性线索优先于附带学习。
Our visual system is highly sensitive to regularities in the environment. Locations that were important in one’s previous experience are often prioritized during search, even though observers may not be aware of the learning. In this study we characterized the guidance of spatial attention by incidental learning of a target’s spatial probability, and examined the interaction between endogenous cuing and probability cuing. Participants searched for a target (T) among distractors (L’s). The target was more often located in one region of the screen than in others. We found that search RT was faster when the target appeared in the high-frequency region rather than the low-frequency regions. This difference increased when there were more items on the display, suggesting that probability cuing guides spatial attention. Additional data indicated that on their own, probability cuing and endogenous cuing (e.g., a central arrow that predicted a target’s location) were similarly effective at guiding attention. However, when both cues were presented at once, probability cuing was largely eliminated. Thus, although both incidental learning and endogenous cuing can effectively guide attention, endogenous cuing takes precedence over incidental learning.
