Research Interests

The focus of my research is on the interactions between attention, memory, and mood. Some of my studies use sad mood inductions to explore these interactions (an NSERC-supported research program), whereas others examine attention and memory in depressed individuals and individuals vulnerable to depression (research funded by the Canadian Institutes of Health Research). My graduate students and honours thesis students are always collaborators in this research. We use eye gaze tracking in many of these studies to examine attention to emotional information over extended intervals (e.g., Newman & Sears, 2015; Soltani et al., 2015; Sears, Newman, Ference, & Thomas, 2011; Sears, Thomas, LeHuquet, & Johnson, 2010). We also investigate the interpretation biases associated with depression and depressed mood (e.g., Bisson & Sears, 2007; Sears, Bisson, & Nielsen, 2011; Stea, Lee, & Sears, 2013). Visit the Cognition and Emotion Lab website for more information.

For Students

Each year I consider applications from students interested in our graduate programs (MSc and PhD). If you are interested in pursuing graduate studies under my supervision please contact me well in advance of the December application deadline to discuss research opportunities. Undergraduate students interested in the honours program and possible honours thesis projects should contact me in the fall session (January 23 is the deadline for applications to the honours program). For students interested in Psychology 499 (Research Experience in Psychology), you can contact me anytime to discuss possibilities, but remember that you will need to register for the course prior to the fall or winter session registration deadline. 

To date I have supervised 18 graduate student theses (14 MSc and 4 PhD) and 20 honours thesis students (BA/BSc). I have been a member of the thesis supervisory committee of 58 MSc/PhD students (not including my own students). My graduate and undergraduate trainees are always coauthors on my publications and they have had good success winning Tri-Council scholarships (NSERC, CIHR, SSHRC). You can learn more about my lab, my graduate students, honours students, and our research activities by visiting the Cognition and Emotion Lab.
