视觉表象生成系统及其影响因素

视觉表象是在记忆基础上产生的类似知觉的信息表征, 也是人们在日常生活中不可或缺的心理活动之一。本综述介绍了该领域中比较有影响力的表象计算理论模型, 并进一步归纳了视觉表象生成系统的成分及其对应的神经基础。分析结果强调了初级视觉皮层作为“视觉缓冲器”是生成表象的主要机能结构, 以“视觉缓冲器”为基础的表象生成系统的机能受多重因素影响。本综述有助于对视觉表象生成系统形成全面的认识, 促进视觉表象实质的进一步研究。

The system of visual imagery generation and its effect factors

Visual mental imagery is defined as the representation of visual information in human brain without external sensory stimuli, which plays an essential role in most of human’s mental activities. In this paper, we reviewed a theoretical computational model of visual mental imagery and summarized the essential components of visual imagery generation system with its corresponding neural basis. This paper highlights that the great importance of primary visual cortex in visual imagery process as it works as a “visual buffer” for generating visual information mentally. Factors that affect the production of visual mental imagery were also outlined. By offering a comprehensive understanding model of the processing of visual mental imagery, this paper may facilitate the further researches on visual mental imagery.
