中文摘要：

注意离散性是注意间歇性地采集外界信息的特性。文章综述了视觉注意离散性的4种实验范式：（1）车轮错觉范式，刺激强度大、实验条件少、被试任务量小，较旱地证实了视觉注意的离散性；（2）视觉探测范式，同时观察了被试的行为表现与电生理信号，确定了视觉注意离散性与神经振荡的关联；（3）线索靶子范式和视觉搜索范式，通过系统地变化SOA大幅提高了行为数据的时间分辨率，直观地探测到注意离散性调制的行为振荡。

英文摘要：

The spotlight of attention is intrinsically rhythmic, which discretely sample a single or multiple objects. This phenomenon is called discrete attention. Here we summarized four paradigms used to investigate discrete attention in visual domain. In the wagon-wheel illusion paradigm, motion direction illusion is experienced. This paradigm is adopted to demonstrate the discreteness of attention. In the visual detection paradigm, participants are asked to detect the near-threshold stimuli, which is used to investigate relationship between neural oscillation and discrete attention. In the high time-resolved cue-target paradigm, a target occurs after a varying interval following a peripheral cue; while the target is embedded among distracters in the visual search paradigm. These two paradigms are developed to vividly show behavioral oscillation patterns.
