Abstract	Neuropsychological research and schizophrenia research are research areas in close proximity, but in some aspects they differ in conception. The following suggestions are made with an awareness of both similarities and differences between the two research fields. From the perspective of 'applying neuropsychological research to schizophrenia research', the following three points are proposed: 1. a 'paradigm shift' is needed to be able to diagnose schizophrenia on neuroimaging, rather than just increasing the diagnostic accuracy; 2. use the principle of 'double divergence' for clinical-anatomical correlations; 3. be careful in interpreting the neural basis of psychological states influenced by social factors. On the other hand, from the perspective of 'applying schizophrenia research to neuropsychology', the following three points are proposed: 1. use global indicators in a generous way, 2. take a bold step in 'understanding', and 3. focus on the patient and life perspectives.
