Why do people process emotional information differently? Are there individual differences in the way that emotional information is attended to and remembered that increase one’s vulnerability to mood disorders? Are there individual differences that help protect one from mood disorders? How can cognition researchers distinguish between typical and atypical attention and memory for emotional information? My research is focused on answering these and related questions.

Many of our studies examine attention and memory biases in depressed, never depressed, and depression-vulnerable individuals, using eye gaze tracking to measure attention to emotional stimuli (e.g., Fernandez, Quigley, Dobson, & Sears, 2022; Newman, Quigley, Fernandez, Dobson, & Sears, 2019). We also use mood inductions and priming procedures to study interactions between attention, memory, and mood, in younger and older adults. My graduate students and honours thesis students are always collaborators in these studies. I also pursue research on attention and memory biases associated with body image and eating disturbances (with Kristin von Ranson), and research on cognitive and affective factors in disordered gambling (with Daniel McGrath). Visit the Cognition and Emotion Lab website for more information.

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 November application deadline to discuss opportunities. Undergraduate students interested in the honours program and possible honours thesis projects should contact me early in the fall session (the deadline for applications to the honours program is in January). For students interested in Psychology 499 (Research Experience in Psychology), you can contact me anytime to discuss possibilities. 

To date I have supervised 22 graduate students (MSc/PhD) and 28 honours thesis students (BA/BSc). My graduate and undergraduate trainees are always co-authors on our lab's publications and they have had good success winning Tri-Council scholarships (NSERC, CIHR, and 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.
