A combined lexical and segmental therapy approach in a participant with pure alexia

ABSTRACTBackground: Pure alexia is characterized by effortful left-to-right word processing, leading to a pathological length effect during reading aloud. Results of previous therapy outcome research suggest that patients with pure alexia tend to develop and maintain an adaptive sequential reading strategy in an effort to cope with their severe deficit and at least master a slow and laborious reading mode.Aim: We applied a theory-based, strategy-driven and eye-movement-supported therapy approach on HC, a participant with pure alexia. Our intention was to help optimizing his very persistent sequential reading strategy, while concurrently facilitating fast parallel word processing.Methods & Procedures: Therapy included a systematic combination of segmental and holistic reading as well as text reading components. Exposure duration and font size were gradually reduced. Following a single case experimental reading design with follow-up testing, we assessed reading performance at four testing points focusing on...
