The thesis is aimed at the issue of developmental dysphasia in
terms of linguistic levels. It is divided into one theoretical
and one practical part. The theoretical part consists of three
main chapters which deal with the definition of developmental
dysphasia, the symptomatology of developmental dysphasia in
terms of linguistic levels and the therapy of developmental
dysphasia.
The first chapter is focused in detail on definition and
terminology, etiology, diagnosis and academic success of
students with developmental dysphasia. The second chapter
analyses more closely the different linguistic levels in terms
of symptomatology of the impaired communication abilities. The
third chapter is dedicated to the development of vocabulary,
speech development with a focus on grammar and syntax, the
development of pronunciation, the auditory perception and the
integration of the individual into the collective, including
the role of the family.
The practical part was implemented in the form of qualitative
research on a selected group of six boys of preschool age. Its
main objective was to analyze the developmental dysphasia in
terms of language levels. Case studies of individual boys were
carried out. Transcriptions were made from the audio
recordings. The results of the research were analyzed and
proposals were drawn for the practice.
