A novel mobile technology application for individuals with primary progressive aphasia (PPA) was developed and evaluated as an AAC intervention. CoChat is a simulated social media app which creates lexical displays synthesized from a user’s self-generated photos, comments from social network contacts, device metadata, and a curated list of key words. CoChat was developed to support language co-construction and word finding skills during conversation. A single case design research study was implemented to evaluate CoChat. Ten adults with PPA engaged in five community­ based activities with an RA, taking one photo for each activity. Photos were immediately sent to a wizard who provided 10 comments about the picture. The app automatically surrounded each photo with10 words: six from the simulated social network; four from the language model as a suggestion word set. Participants then described the community activities to familiar partners in three conditions: conversations without technology, with photos only and with CoChat (10 relevant words surrounding a photo). Conversations were videotaped and analyzed for # of target words produced in each condition; # details understood by communication partner in each condition; participant and partner satisfaction with each condition. Initial results reveal that there is a trend toward increased lexical retrieval and partner understanding when CoChat is used during conversations. Results will be discussed in detail. This research takes an initial step toward the creation of adaptive language prostheses that augment lexical access and word use in PPA to improve conversation and functional outcomes even as skills are lost.
