This study investigates speech and attention abilities in older adult speakers and individuals with brain injuries such as stroke or traumatic brain injury. The purpose is to understand how these conditions affect language and attention. A brain injury is any harm to the brain that can affect how a person talks, thinks, or pays attention. Aphasia is a condition that affects a person's ability to communicate, often occurring after a brain injury.
Participants will take part in two sessions. During these sessions, they will speak about topics provided by the researchers and complete tests to assess their attention. The first session lasts 90 minutes, and the second session, which occurs about 10 days later, lasts 60 minutes.
- Who can participate: Participants must be native English speakers. Individuals with a brain injury and language problems for at least 6 months, aged 18 and older, are eligible. Typical adult speakers aged over 45 with no cognitive issues or brain injuries can also participate.
- Study details: Participants will engage in speaking tasks and attention tests during two sessions.
- Study Visits: The study requires 2 visits.
