Semantyka leksykalna w badaniach nad zaburzeniami należącymi do spektrum autyzmu
Lexical semantics in the research on autism spectrum disorder

Summary/Abstract: The article deals with the problem of lexical semantics disorders in autism spectrumdisorder (ASD). In the introduction, it is pointed out that semantics is analysedless frequently than pragmatics in ASD research. Having attempted to explain thisdisproportion, the author emphasises the need for further research into semanticsin ASD. Then, the concepts of lexical ability, semantic ability, lexical competence andsemantic competence are discussed refering it to people with ASD. The important roleof the qualitative aspect in research is indicated. The article characterizes two perspectivesof research on semantics in ASD – descriptive and explanatory. It is highlighted that people with ASD demonstrate considerably diverse language skills. Arguments areprovided in favour of undertaking research into lexical semantics as beneficial for speechtherapy theory and practice. It is postulated to take into account all linguistically andculturally relevant features of lexemes. The issues that should be addressed in futureresearch are: multiple semantic variations in vocabulary, paradigmatic and syntagmaticrelations, references to the ways words mean. The author hypothesizes which groupsof lexemes may be especially interesting as material for research on lexical semantics inASD. She also mentions the problem of applying linguistic theories (structural linguistics,cognitive linguistics) in speech therapy.
