Neuropsychological Characteristics of Verbal and Non-Verbal Fluency in Schizophrenia Patients

Verbal and non-verbal fluency tests engage complex cognitive processes and executive functions in patients. As a result, the interpretation of their results is often complicated and requires special competences. The tests are popular neuropsychological tools used for assessment of verbal memory, executive functions, visual-spatial abilities and psychomotor speed in patients with mental and neurological disorders. The aim of this paper is to discuss diagnostic tools used for measuring both types of fluency (verbal and non-verbal), test interpretation methods, as well as their usefulness in clinical diagnostics and scientific research.
