Study Details

Measuring Language Between People with Aphasia and Neurotypical Adults

(IRB#: IRB_00149485)

The study's purpose is to measure event-related potentials (ERPs) of people with aphasia or neurotypical adults. Aphasia is when a person may be unable to speak well after a brain injury such as a stroke and head trauma. Neurotypical is when a person has standard brain functions such as the ability to speak or write without much effort. An ERP is a brain response to when a person may feel, think, speak, write, and move. An ERP is measured through an electromagnetic encephalogram (EEG). An EEG is a cap worn on top of the head with electrodes attached to the cap. The electrodes are a safe way to allow a small amount of electricity to measure a persons brain activity. Participants will read sentences while having their brain activity measured with an EEG. This study will help us better understand language challenges and develop effective ways of language recovery for people with aphasia. Participants will receive $10 an hour for in-person participation at a University of Utah clinic or online using a computer or phone.
