Welcome to Anxiety Studies

Why study anxiety?

Anxiety is a normal response that is necessary to our survival. Anxiety orients us to danger and prepares our bodies to either challenge or escape it. Anxiety can also motivate us to take action, such as when we realize we have an important deadline, and it can give us a bit of a thrill, such as when we ride a roller coaster or play a fast-paced competitive game. Our world would be more dangerous if we were unable to become anxious.

But for some people, anxiety is the norm, not the exception, and their fears make it hard for them to meet family, work, and social obligations. The Anxiety Studies Division seeks to understand anxiety better so we can better help people who suffer from it.

Who are we?

We are full-time faculty members in the University of Waterloo’s Department of Psychology who have a shared interest in understanding the development and persistence of anxiety problems. Currently, the Anxiety Studies Division includes Dr. Christine Purdon and Dr. David Moscovitch, the graduate students they supervise, and the research assistants who work for them.
