Abstract: A key element of the distinction between explicit and implicit cognitive functioning is the presence or absence of conscious awareness. The neuropsychological disorders of brain-injured patients offer the probability to discuss the “pure” abruption of explicit/implicit processing. Through the study about the blindsight, hemi-neglect and agnosia, it is indicated that the implicit processing is intact but the explicit processing is impaired, and it is showed that the implicit and the explicit processing have different neural basis. But what is the possible neural basis of this distinction and the nature of the abruption is waiting for the further studies. The reverse impairment of implicit/explicit processing in neuropsychological disorders of visual perception is a domain that not put up

Key words: explicit, implicit, abruption, neuropsychological disorders
