Roles and Responsibilities

The project members consisted of Rachel Shatto and Mara Goodman. Both authors contributed to

the production of this thesis and to furthering the research in long-term aphasia recovery. The majority of

the project was completed in collaboration, however for some sections one student assumed the majority

of the responsibility. The data from our research were interpreted with assistance from our thesis advisor

Dr. P¨¦lagie Beeson.

I, Rachel Shatto, was responsible for the extensive literature review which made up the

introduction of our thesis. This included performing an exhaustive search of the literature for articles

relevant and comparable to the research we did here. Dr. Beeson also assisted in the literature review

process. The written discussion/interpretation portion of our analysis was also my responsibility. I

elaborated on the meaning of our data and compared our research to the findings of others. Collaboration

between Mara Goodman and I was necessary for the final editing and building cohesion in the paper.

Abstract

Aphasia is an acquired language impairment associated with damage to the languagedominant hemisphere. In this study, aphasia recovery outcomes were examined from 73

individuals who participated in aphasia treatment over extended periods of time. Aphasia

quotient (AQ) scores attained from the Western Aphasia Battery (WAB) were used as

measurement of language change as well as classification of severity for all individuals. Across

all participants, language performance improved an average of +5.62 AQ points over about four

years. The slope of the recovery curve for the entire population was positive and significant.

When participants were examined relative to aphasia severity, those in the moderate category

showed the most improvement over time with an average increase of 11.68 AQ points. Age at

the time of aphasia onset was a significant predictor of improvement in language performance as

measured by the WAB, suggesting that younger individuals have a better prognosis for continued

improvement over the years following the event. The findings from the study indicated that

many individuals continue to improve even at relatively long times post onset, and that

significant language gains can be made regardless of the amount of time passed, especially when

the recovery process is not complicated by the effects of advanced age.
