About Dr Suzanne Stewart

Suzanne joined the Department of Psychology in September 2012 after conducting post-doctoral research with the “Early Detection and Intervention Evaluation for people at high-risk of psychosis-2” (EDIE-2) and the “Manchester Self-Harm Project” (MaSH) at the University of Manchester.


Suzanne teaches research methods to both first year (PS4005) and second year (PS5015) students and supervises research dissertations for both undergraduates (PS6001) and postgraduates (PS7112). She is co-module leader on the Psychopathology (PS6007) and Research Dissertation (PS6001) modules.


Suzanne’s research interests lie in the areas of social cognition and clinical psychology. In the past, she has conducted research into theory of mind, alignment, and insight in psychosis as well as therapeutic interventions for both individuals with psychosis and those who are at risk of developing psychosis. 

She is also interested in social cognition in both healthy and clinical populations and is currently working with colleagues on publishing further results from the EDIE-2 trial. Other ongoing projects involve embodied cognition; the influence of emotional inferences in reading on the perception of facial emotions; the links between adult theory of mind, fiction reading, and childhood fantasy play; the connections between theory of mind, cognition, emotional intelligence, and lie detection; and media influences on body image and satisfaction.
