我们调查了在场景中的注意力的部署是否可以更好地解释视觉显着性或认知相关性。在两个实验中，参与者在场景照片中寻找目标物体。这些物体出现在语义上合适的位置，但在场景中并不明显。搜索是快速和有效的，参与者更有可能寻找目标，而不是突出的区域。这种差异在第一次注视时就很明显，无论参与者是否熟悉搜索目标的视觉形式。在大多数试验中，显著区域没有固定。在两个实验中，观察到所有24名参与者的关键效应。我们概述了一个认知相关性框架来解释场景中注意力和固定的控制。
We investigated whether the deployment of attention in scenes is better explained by visual salience or by cognitive relevance. In two experiments, participants searched for target objects in scene photographs. The objects appeared in semantically appropriate locations but were not visually salient within their scenes. Search was fast and efficient, with participants much more likely to look to the targets than to the salient regions. This difference was apparent from the first fixation and held regardless of whether participants were familiar with the visual form of the search targets. In the majority of trials, salient regions were not fixated. The critical effects were observed for all 24 participants across the two experiments. We outline a cognitive relevance framework to account for the control of attention and fixation in scenes.
