The purpose of this research is to determine how best to represent information in AAC systems for people with moderate/severe/profound chronic aphasia. The researcher hypothesized that people with moderate/severe/profound chronic aphasia will use AAC systems more efficiently and effectively when information is represented through personally-relevant highly contextualized pictures rather than iconic symbols or non-personally relevant contextualized pictures. Data was collected from eight participants with moderate/severe/profound chronic aphasia. Results from eight participants indicated, that people with moderate/severe/profound chronic aphasia prefer and identify personally relevant highly contextualized pictures with greater accuracy than iconic symbols or non-personally relevant contextualized pictures
