An EEG Study of Auditory Perception in People with and without Schizophrenia

Research Question:
Are there differences in how the brain processes sounds in people with and without schizophrenia? If so, are these differences related to specific symptoms of schizophrenia, and can this knowledge help us develop better treatments?

Basic Study Information

The purpose of our study is to better understand how the brain processes sounds, including speech. We are investigating this in people with and without psychiatric conditions. One of our primary aims is to determine how these processes may relate to specific experiences and symptoms in conditions such as schizophrenia, schizoaffective disorder, and schizophreniform disorder, with the goal of using this knowledge to develop more effective treatments. In order to study how the brain processes sounds, we use a technique called electroencephalography, or EEG. For EEG, a person wears a comfortable elastic cap with sensors attached to it that are able to record brain activity. In these sessions, subjects listen to short audio clips while EEG is recording; this allows us to measure brain responses to sounds. This study also includes interviews about current and past psychiatric symptoms and treatment, as well as a few short tasks, questionnaires, and a hearing test. The study typically involves 4-5 visits, with each about 2-3 hours long. Subjects are paid $30 an hour, as well as a $30 bonus if they complete all study activities. Transportation costs are also covered, and free snacks are provided.
