Maggie Toplak, Ph.D., C. Psych.

My training and research interests span cognitive science and clinical research. I am interested in studying individual differences in judgment and decision-making and cognitive abilities in typically developing samples and in developmental psychopathology. I graduated with a PhD from the School and Clinical Child Program, University of Toronto and I am registered as a clinical psychologist with the College of Psychologists of Ontario.


Current Graduate Students

Rachael Lyon

Rachael is a third year PhD student in the Clinical-Developmental Psychology Program. She is also in the Clinical Neuropsychology stream. Her master’s research investigated the extent to which executive function task performance and parent-ratings of ADHD symptomatology capture age related variance in a longitudinal sample of children and youth. Her dissertation focuses on the relationships among technology use, mental health and difficult behaviours in children with ADHD which will be used to develop a brief intervention to support parents. Rachael is completing her breadth comprehensive research project examining parent readiness for change in the I-InTERACT-North program at SickKids, an intervention for parents of young children with neonatal brain injury or congenital conditions. Her general research interests center around brain-behaviour relationships and treatment innovation in children and youth with neurodevelopmental and acquired brain disorders

Elizabeth Wanstall

Elizabeth is in the third year of her PhD in Clinical-Developmental Psychology. For her MA thesis, she examined an updated version of the Unstructured Performance Task (i.e., UPT-2) in a sample of typically developing children. Her dissertation research focuses on technology use and behaviours in children with ADHD, with the goal of developing a brief intervention to support parents. Broadly, Elizabeth’s general research interests are in the area of neuropsychological abilities in childhood illness and neurodevelopmental disorders.

Joshua Doidge

Josh is currently in the fifth year of his PhD. Josh’s clinical and research interests range across the developmental lifespan from childhood to adulthood. His dissertation involves examining adolescents’ uses and attitudes towards technology and how they relate to miserly processing tendencies. Josh’s dissertation will also involve exploring how miserly processing and technology relate to other areas of importance for adolescents including academic achievement and risk-taking. For his MA, Josh conducted a meta-analytic review of gender differences between Typically Developing samples and ADHD samples on delay of gratification and temporal discounting tasks across development.

Kaitlyn Butterfield

Kaitlyn is in the second year of her Masters degree. She is examining  subjective ratings of task difficulty, effort required, and affective experience on the Unstructured Performance Task (UPT-2) in a community sample of children. Her general research interests include pediatric neuropsychological disorders.
