The study was conducted on patients diagnosed with schizophrenia. It is concerned with the analysis of speech disorders (referred to as schizophasia in this experimental group) and selected cognitive functions. The study is divided into two parts. The first one contains conversations with patients on topics relating to their most immediate environment. They served as a basis for the evaluation of two aspects: lingustic phenomena according to N. Andreasen’s The Scale for the Assessment of Thought, Language and Communication, as well as grammatical, semantic and syntactic disorders according to A. Czernikiewicz’s Krótka Skala Oceny Schizofazji [Short Scale of Schizophasia Evaluation]. The second part is concerned with the assessment of the functioning of selected cognitive processes, i.e. semantic fluency and short-term memory. The results obtained have been divided into quantitative and qualitative analyses.The quantitative analysis of the first part has demonstrated that the most frequent linguistic phenomena among patients with schizophasia are: excessive attention to detail, digressiveness, illogicality. Apart from that, patients had the greatest difficulties with pragmatic coherence of their utterances (90% of the sampled patients). The study of selected cognitive functions has demonstrated that patients diagnosed with schizophrenia fared worse in semantic fluency and short-term memory tests. However, it is the qualitative analysis that turned out to be the most interesting element of the study. It identified some interesting phenomena in cognitive functions, which cannot be found in the control group. They are connected with excessive abstraction, specific parts of speech, neologisms, numerous perseverations, interjecting loose associations and changing the plot of a story. There is a relation between the appearance of some linguistic phenomena and the results of cognitive functions tests carried out on the experimental group. Although the general correlation between these two aspects is not high enough to be considered statistically relevant, in the most severe cases, the appearance of linguistic phenomena during the testing of cognitive functions proves that schizophasia-type disorders considerably affect semantic fluency and short-term memory.
