Research Interests

  • Discrimination in the law
  • Legal decision-making
  • The influence of race, gender, and other extralegal information on juror 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


Dr. Maeder became a faculty member of the Institute of Criminology and Criminal Justice in 2008.  She is also cross-appointed in the Department of Psychology. Dr. Maeder studies the role of psychology in the law and legal decision-making, particularly with respect to juries and public policy.  Her current research projects include studying the effects of extralegal information (e.g., race and racialization, gender, and pre-existing attitudes) on juror and jury decision-making, legal decision-making in NCRMD trials, and lay conceptions of punishment.  She is the director of the Legal Decision-Making Lab at Carleton, and her work has been funded by SSHRC (Social Sciences and Humanities Research Council of Canada) and APLS (American Psychology-Law Society).
