视觉搜索过程中的眼跳及其机制

该文对视觉搜索过程中的眼跳及其时间进程、神经机制及相关的理论与模型等方面研究进行了回顾。发现内外源性眼跳得到了研究者的普遍关注，对眼运动记忆、返回抑制及眼跳时间进程的研究尚存在分歧。关于眼跳的神经机制，额叶眼动区与上丘分别被认为是眼跳的关键区与指令发出者。尽管不同的眼跳理论与模型对眼跳现象给出了各自的解释，但都不尽完善，尚需对这些理论进行整合或者提出新的解释模型。文章还对未来的研究进行了展望

The Saccades and Its Mechanism in the Process of Visual Search

his paper holds a retrospective and global view on several aspects regarding the saccades in the process of visual search, including of its timing process, its nerve mechanism, and related theory and model as well. The research found that most attentions are paid to the endogenous saccades and exogenous saccades. But there are many disagreements in the research of eye movement memory, inhibition of return (IOR) and saccades timing process. As far as the nerve mechanism of saccades is concerned, it’s said that the frontal eye fields (FEF) and superior colliculus (SC) are the sensitive area and instruction senders of saccades respectively. Although different theory and model have different explanations respectively, all these explanations cannot be ideal. As a result, to modify and integrate these theories and propose a new one becomes urgent and necessary. At last, this paper put forward to a direction for future research
