Studying Psychosis Using Brain Waves

Psychosis is defined as a disruption in one’s experience with reality, whereby an individual develops implausible beliefs, confusing speech or hallucinations. It is a highly distressing mental disorder, which can disrupt a person’s daily life and normal functioning.

Our research group aims to measure changes in the brain’s electrical signals during various tasks. We are trying to understand the distinct changes in activity that occur in individuals who are at clinical high-risk for psychosis compared to healthy individuals. We are also interested in understanding these changes in cannabis users.

Our study will last approximately 3 to 4 hours, during which the participant will complete:

  1. Interviews and questionnaires about medical and psychiatric symptoms
  2. Cognitive tests of language and memory
  3. An EEG test, where we will measure brain waves while participants complete cognitive tasks, and watch and listen to short videos.

We are looking for volunteers who meet the following criteria:

  • age between 16-35 years
  • have learned English before age 5
  • no alcohol or drug problem (excluding cannabis)
  • no current or past neurological conditions

You will receive compensation for your participation.
