Attention shapes what we see and what we act upon by allocating limited resources to certain parts of visual display in a selective and adaptive manner. While most previous studies in visual attention mainly focused on the attentional distribution over space or features, recent studies have revealed that temporal dynamics also plays a crucial function in visual attention. This paper reviews the representation, function and neural mechanism of temporal dynamics in visual attention from the following four aspects: (1) Tracking dynamic structure of external stimulus by attention; (2) Intrinsic dynamic characteristics of attention; (3) Time-based multiple object representation; (4) Relationship between visual dynamics and classical attentional phenomena. We propose that the dynamic structure and temporal organization are fundamental to visual attention, and the research on it might provide new solutions to many unresolved issues in visual attention research.
注意力通过以一种选择性和适应性的方式将有限的资源分配到视觉显示的某些部分，塑造了我们所看到的以及我们据此采取的行动。虽然之前大多数关于视觉注意力的研究主要集中在注意力在空间或特征上的分布，但最近的研究表明，时间动态在视觉注意力中也起着关键作用。本文从以下四个方面综述视觉注意力中时间动态的表征、功能和神经机制：（1）通过注意力追踪外部刺激的动态结构；（2）注意力的内在动态特征；（3）基于时间的多对象表征；（4）视觉动态与经典注意力现象之间的关系。我们认为动态结构和时间组织是视觉注意力的基础，对其研究可能为视觉注意力研究中许多未解决的问题提供新的解决方案。
