为了进行有效的视觉搜索，视觉注意力必须被适当地引导到目标上。以前的研究表明，当搜索对象的空间配置或对象身份重复时，可以迅速将注意力引导到目标上。这种现象被称为语境线索。在这项研究中，我们研究了学习空间配置、物体身份以及两者的组合对视觉搜索的影响。结果表明，即使在空间构型和物体同一性完全相关的情况下，被试也能学习空间构型的背景，但不能学习物体同一性的背景(实验1)。另一方面，当只重复物体同一性时，可以观察到同一性学习的效果(实验2)。此外，在一些实验中，当每个背景都是预测目标的相关线索时，观察到配置学习和身份学习的相加效应(实验3)。参与者只能学习与目标位置相关的语境(实验4)。这些发现表明，当多个语境是多余的时，语境学习会选择性地发生，这取决于目标位置的可预测性。
To conduct an efficient visual search, visual attention must be guided to a target appropriately. Previous studies have suggested that attention can be quickly guided to a target when the spatial configurations of search objects or the object identities have been repeated. This phenomenon is termed contextual cuing. In this study, we investigated the effect of learning spatial configurations, object identities, and a combination of both configurations and identities on visual search. The results indicated that participants could learn the contexts of spatial configurations, but not of object identities, even when both configurations and identities were completely correlated (Experiment 1). On the other hand, when only object identities were repeated, an effect of identity learning could be observed (Experiment 2). Furthermore, an additive effect of configuration learning and identity learning was observed when, in some trials, each context was the relevant cue for predicting the target (Experiment 3). Participants could learn only the context that was associated with target location (Experiment 4). These findings indicate that when multiple contexts are redundant, contextual learning occurs selectively, depending on the predictability of the target location.
