The primary aim of the article was to define the relation between semantic satiation effect, hiperactivation of semantic network and language disorders in schizophrenia. The author presents a classification of pathological linguistic phenomenon in schizophrenia based on an access to the form and meaning of the words criterion, discusses the associational activation hypothesis which predicts that the main source of language disorders in schizophrenia is the disturbances of activation process in semantic network. In the article the attempt was made to extend this hypothesis to the results of research on semantic satiation effect. Semantic language disorders in schizophrenia could be explained as a result of hyperactivation of semantic network whereas formal language disorders are based on the effect of temporary loss of meaning of words.Semantic satiation effect should be taken into account as a possible couse of formal language disorders in schizophrenia.
