This study investigates the relationship between verbal fluency, nonverbal fluency, and discourse abilities in older adults with acquired brain injury. It also examines how education level, age, and activity levels affect these communication skills. An acquired brain injury is a condition where the brain is damaged after birth, affecting how a person communicates and performs everyday tasks.

Participants will be involved in activities that assess their verbal, nonverbal, and discourse skills. These activities are designed to understand how different factors influence communication abilities in older adults. The study does not include any treatment or medication.

• Who can participate: Participants must be older adults who are native English speakers. They should either have no history of acquired brain injury or have experienced a mild acquired brain injury. They must have normal vision and hearing, with or without correction. Exclusion criteria include a history of alcohol or substance abuse, dementia, psychiatric illness, or clinical depression within the past six months.
• Study details: Participants will engage in activities to assess their communication skills. The study will compare skills between those with and without a mild acquired brain injury. No payment will be provided for participation.
