Alison Chasteen is a Full Professor in the Department of Psychology at the University of Toronto and a social psychologist with specialized training in aging and cognition. She studies stereotyping, prejudice, and stigma from both the perceiver's and the target's perspectives.

Alison Chasteen received her BA from Kalamazoo College and her Ph.D. from Washington University in St. Louis. She completed a post-doctoral fellowship at the University of Michigan before joining the University of Toronto. She joined the Department of Psychology at the University of Toronto in 1999 and was awarded tenure and promoted to Associate Professor in 2005. In 2015, she was promoted to the rank of Full Professor. Professor Chasteen has previously served as the Graduate Chair of the Tri-Campus Graduate Department of Psychology (2018-2021), and prior to that appointment as the Acting Graduate Chair and Acting Graduate Director. Professor Chasteen was appointed Acting Associate Dean, Unit-Level Reviews, effective July 1, 2022.

Dr. Chasteen is a Fellow of the Gerontological Society of America as well as of the Society for Experimental Social Psychologists. She and her students have developed a well-validated measure for assessing ageist attitudes toward older people (Cary, Chasteen, & Remedios, 2017), as well as another measure for assessing older adults' feelings of age-based stigma (Kang & Chasteen, 2009). As part of a CIHR-funded Catalyst Grant, Dr. Chasteen and colleagues demonstrated that older adults' negative views of aging impact not only their cognitive self-perceptions and function but also their self-perceptions of hearing ability and performance (Chasteen et al., 2015). This was the first study to specify the role that older people's age stereotypes and feelings of age stigma play in multiple modalities of their lives.

Dr. Chasteen's current work focuses on better understanding older adults' experiences of ageism in daily life across numerous contexts.
