In accordance with TalkBank rules, any use of data from this corpus must be accompanied by at least one corpus reference. If none is given, please use the primary AphasiaBank reference:

The Unfamiliar Objects task requires participants to view images of objects and generate questions to determine the purpose of the object. Pictures of these objects are located here.
The participants' questions were transcribed in CHAT and coded (on a coding tier in the transcript) using a portion of Stivers & Enfield’s question-response coding scheme (2010). Specifically, questions were coded as either polar (positive or negative), alternative, or content (who, what, when, where, and why).
Some of the RHD and neurologically healthy participants are from the RHDBank database and did this task as part of the standard discourse protocol. Their files have the name "minga" or "nazareth" in them. The others did this task as part of another study and have numerical filenames such as 101". Videos are available for RHDBank participants only. The media file links given above are the full RHDBank discourse protocol recordings. The transcripts are time-linked to the media files and will play the relevant section.
Demographic data and other test results are available for the participants who did this as part of the RHDBank protocol. Those spreadsheets are located here at the Demographics Collection link and the Test Results Collections link.
