The Existence,Mechanism of Action and Epistemological Significance of Early Vision
Vision is an important ability for individuals to understand the world,and the information obtained through vision is a necessary condition for knowledge formation.The authenticity and objectivity of visual informa-tion closely affect the reliability of knowledge.Discussions about vision mainly focus on the division of the visual process.One perspective views it as holistic,while the other perspective divides it into early vision and later vision stages.However,there has been ongoing debate about the existence of the early vision stage due to its very brief duration.In recent years,clinical cases of visual agnosia,the mechanism of attentional selection and experimental evidence from behavioral science have all demonstrated the objective existence of the early vision stage,which can help individuals make rapid reflexive responses under specific circumstances.The existence of the early vision stage has had profound implications for knowledge formation,the interpretation of mind-body relationships and the un-derstanding of the external world by individuals.
