NeuropsychologicalCharacteristics of Verbal and Non-verbal Fluency of SchizophreniaPatients

Schizophreniais a disease that affects a person’s ability to execute basicfunctions, affects their ability to speak and express themselvesfluently. The article: Tyburski, E., Sokołowski, A., Chęć, M.,Pełka-Wysiecka, J., &amp Samochowiec, A. (2014). NeuropsychologicalCharacteristics of Verbal and Non-Verbal Fluency in SchizophreniaPatients. Archivesof Psychiatric Nursing,tries to look at the correlation between brain activity and verbaland non-verbal fluency in Schizophrenia patients. The authors of thearticle also revisit earlier tests on the role of semantic fluency asa method, used to predict first-episode psychosis. The article looksat some of the tools used in measuring both verbal and non-verbalfluency and explores their importance in diagnosis and research ofSchizophrenia (Tyburski,Sokołowski, Chęć, Pełka-Wysiecka, &amp Samochowiec, 2014).

Theauthors have used a number of publications to support theirarguments. Most of the publications are journal articles that havebeen written by experts in the field of Neuropsychology. They alsoborrow from previously done research and studies that look at thetests used to measure verbal and non-verbal fluency. The article alsolooks at the possible results of the tests, and how the tests can beinterpreted (Tyburski et al., 2014). The authors also look at some ofthe factors that affect verbal and non-verbal fluencies. The casepresentation is perfect as the authors try as much as possible todraw conclusions using studies that have already been conducted. Theydo not make their own conclusions and are careful to cite anyinformation that they borrow from the works of other people. Thearticle is written to help medical practitioners in the diagnosis ofSchizophrenia by exploring the tests that can be used in diagnosingthe disease.

of key ideas

InNeuropsychology, fluency can be divided into verbal and non-verbal.Verbal fluency is further divided into expressive and perceptualfluency. Expressive fluency is further divided into verb, creative,rhyme, semantic, phonemic, abstract, affective, syntactic andassociative fluency. Nonverbal fluency can be divided into drawingand daily actions fluency. Drawing fluency can be further dividedinto spontaneous and arbitrary fluency. Executive function,psychomotor speed, verbal memory disorder and spatial visibility aresome of the factors that verbal and non-verbal fluency tests focuson. “Results obtained by means of the discussed methods can be usedto draw conclusions concerning the performance levels of verbalmemory, executive functions, spatial visual ability and psychomotorspeed” (Tyburski et al., 2014). In order to test for Schizophrenia,tests that involve giving tasks to particular parts of the brain areused. The brain regions that are usually tested include thepre-frontal cortex.


Thearticle explores the tests used to diagnose patients withSchizophrenia. The article can help nurses interpret the results ofthe various tests. It will also help them to establish which testsare effective since the article looks at some of the previously doneresearch on the diagnosis of schizophrenia. In addition, the articlewill further assist in research about schizophrenia and itsdiagnosis. It is important to note that more research still needs tobe done on the topic since the authors have not exhausted about thevarious tests, the efficiency of the tests and how to interpret theresults.
