Research Interests

  • Discrimination in the law
  • The influence of race/racialization, gender, and other extralegal information on juror and jury decision-making
  • The Not Criminally Responsible by Reason of Mental Disorder (NCRMD) defence – effects of education, attitudes toward mental illness, and punishment orientation on jurors’ decisions
  • Lay conceptions of punishment

Dr. Maeder’s scholarship explores social psychological principles in the criminal legal system. Her research projects include investigating jury racial composition on deliberations and decisions in trials involving racialized accused, examining the efficacy of jury instructions, identifying sources of bias in NCRMD (Not Criminally Responsible on account of Mental Disorder) trials, and determining the reasons that people punish. With training in law and psychology, her work scrutinizes the interplay of systemic and individual factors in perpetuating discrimination in the legal system.

She is the director of the Legal Decision-Making Lab at Carleton, and a member of the Data Justice Lab. Her work has been funded by SSHRC (Social Sciences and Humanities Research Council of Canada), APLS (American Psychology-Law Society), and CBA (Canadian Bar Association).
