Research Interests

My research examines individual differences in cognition, attention, and memory that are associated with mood and anxiety disorders, aging, and body image and eating disturbances. In the lab we often use sad mood inductions or priming procedures to study interactions between attention, memory, and mood (an NSERC-supported research program). One focus of our research is attention and memory biases in depressed individuals and individuals vulnerable to depression. My graduate students and honours thesis students are always collaborators in this research. We use eye gaze tracking in many of our studies to examine individual differences in attention to emotional stimuli (e.g., Sears et al., 2019; Speirs, Belchev, Fernandez, Korol, & Sears, 2018; Newman & Sears, 2015). 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 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. 

I have supervised 19 graduate student theses and 22 honours thesis students (BA/BSc). I have been a member of the thesis supervisory committee of 60 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 thesis students, and our research activities by visiting the Cognition and Emotion Lab.
