Perception is a process in which the subject perceives the world through the senses and makes a comprehensive judgment based on the relation-ship between the brain,the body and the surrounding environment.The discussion of whether the process of subject perception is penetrable focuses on whether the perceptual judgment contains a reasoning process,which can not be proved effectively either logically or in fact.According to the objectivity of perceptual phenomena,sensory experience and non-sensory experience are objective and holistic existence.Therefore,perceptual experience is a process of cognitive penetration.From the perspective of psychological immediacy,the process of the subject perceiving things is a direct and quick judg-ment at the sub-personal level,without reasoning process.According to the results of empirical,the judgment and recognition of perception are biased towards stable perceptual experience when encountering stimuli,which is a top-down and automatic comprehensive judgment process of excluding the subject to some extent.Perceptual experience has no fixed boundary,its boundary expands as our cognitive skills grow,and it is always reflected in the process of unconsciously using these skills for perceptual judgment,so,perception is penetrable.
