We know that people with aphasia communicate better than they talk, but we do not have good tests to measure how well they communicate in conversation with others. The purpose of this study is to demonstrate that the test we are developing is correctly measuring what we intend to measure and that it consistently does a good job of measuring success in conversation. Participants will attend four 1-hour sessions over a period of approximately two weeks. All test sessions will be administered over Zoom. In the first two sessions, we will collect the usual measures of language and cognition, including descriptions of pictures. In the second two sessions, participants will view four short video clips, each lasting about 2.5 minutes. After each video, they will describe what they saw and heard to the SLP. After that, they will have a six-minute conversation with a familiar or unfamiliar conversation partner about what they saw and heard. Finally, the conversation partner will retell the story.
