Lexical disorders in
aphasia: A single case in the connectionist model of G.S. Dell (Magisterarbeit)
The
master thesis (Magisterarbeit, supervised by Liedtke/Huber, RWTH Aachen
University) presents an aphasiological single case study. The person with
aphasia received model-based lexical therapy with increasing cueing hierarchies
based on the connectionist model of Gary Dell and colleagues. For the first
time, the method of decreasing/vanishing cues - originally established in the
learning/memory domain - was introduced to the SLT research area and its
significance highlighted (p. 70), and the advantage of the Dell model for
therapy planning was empirically examined. The thesis introduces and reviews
diagnosis and therapy in cognitive neuropsychology, model-based naming
disorders in aphasia, the variety of cueing techniques, the diagnosis in the
connectionist Dell model and the analysis of error types. The empirical part of
the thesis investigates error types in the course of therapy and the effect of
semantic versus phonological cueing-therapy.
