Implicit contextual cuing refers to the ability to learn the association between contextual information of our environment and a specific target, which can be used to guide attention during visual search. It was recently suggested that the storage of a snapshot image of the local context of a target underlies implicit contextual cuing. To make such a snapshot, it is necessary to use peripheral vision. In order to test whether peripheral vision can underlie implicit contextual cuing, we used a covert visual search task, in which participants were required to indicate the orientation of a target stimulus while foveating a fixation cross. The response times were shorter when the configuration of the stimuli was repeated than when the configuration was new. Importantly, this effect was still found after 10 days, indicating that peripherally perceived spatial context information can be stored in memory for long periods of time. These results indicate that peripheral vision can be used to make a snapshot of the local context of a target.

外围视觉在隐式上下文提示中的作用。

隐式上下文提示是指了解我们环境的上下文信息与特定目标之间的关联的能力，可用于在视觉搜索过程中引导注意力。最近有人建议，存储目标本地上下文的快照图像是隐式上下文提示的基础。要制作这样的快照，必须使用外围视觉。为了测试周围视觉是否可以作为隐式上下文提示的基础，我们使用了隐蔽的视觉搜索任务，其中要求参与者在固定注视十字的同时指示目标刺激的方向。重复配置刺激时的响应时间比配置新时的响应时间短。重要的是，这种效果在10天后仍然存在，指示外围感知的空间上下文信息可以长时间存储在内存中。这些结果表明，外围视觉可用于制作目标局部背景的快照。
