空间情境提示效应及其机制

视觉环境中不变的空间布局信息能够引导观察者将注意快速指向特定的位置并促进对该位置上目标物体的识别,这种现象称为空间情境提示效应.在系统回顾以往研究的基础上,对空间情境提示效应的经典研究和实验范式,空间情境学习的性质、内容与过程,以及空间情境提示效应的产生机制和神经基础进行分析梳理.文章在最后总结了以往研究中存在的5个争议性的问题,并指出未来研究可以操纵研究材料和任务难度等关键变量来解决这些问题.

Spatial Contextual Cueing Effect and Its Mechanisms

Invariant spatial configuration of the visual environment can guide observer's attention to specific location and facilitates recognition of the target in it, which is called spatial contextual cueing effect. Based on the systematic review on the previous studies, the present article introduced the classical studies and experimental paradigms of spatial contextual cueing effect, characteristics, content and process of spatial contextual learning, analyzed the mechanisms and neural bases of this effect. Finally, the article carried on the summary of five controversial issues in the previous studies and pointed out that future research could manipulate some key variables, such as materials and task difficulties, to solve these problems.
