Direct And Indirect Treatment Effects In Multilingual People With Aphasia, Aviva Lerman

Dissertations, Theses, and Capstone Projects

Background: Successfully assessing and treating aphasia in multilingual people requires a detailed understanding of the mechanisms underlying language processing in the multilingual population, and the potential impairments to those mechanisms. The balance between spreading activation of language processes via treatment and controlling interference of competing items within the lexico-semantic networks appears to be a key factor in determining whether treatment effects generalise within and across languages in multilingual people with aphasia (Kiran, Sandberg, Gray, Ascenso, & Kester, 2013).

This balance can be exploited through treatment, which, if carefully chosen, should maximise potential within- and cross-language generalisation. One treatment that has …

Caring For Persons With Autism Spectrum Disorder: A Toolkit For Audiologists, Melanie Rosenthal

Dissertations, Theses, and Capstone Projects

As the symptoms of Autism Spectrum Disorder (ASD) can mimic those of hearing loss, an audiologic evaluation is often a component of the differential diagnostic process. These audiologic evaluations can be complicated by social communication deficits, as well as sensory issues demonstrated by individuals with ASD. Typical testing procedures may need to be adapted, as well as multiple appointments may be needed, to obtain sufficient audiologic information. Although there is an abundance of literature suggesting that alternative approaches (i.e. visual schedules, social stories) should be utilized in the audiologic evaluation, there has yet to be a comprehensive toolkit for audiologists …
