PRISM Lab

Welcome to the PRISM (Psychological Research in Investigative Science and Methodology) lab! The PRISM lab is located in the Department of Psychology at Carleton University. The director of the lab is Dr. Kirk Luther.

The goal of our lab is to conduct research that has meaningful impact on real-world practices and advances psychological theory within the forensic field. Our current areas of research include:

1. Improving Investigative Interviewing Practices. The successful resolution of criminal investigations and security threats is fundamentally linked to obtaining high-quality information via investigative interviews. Although substantial progress has been made, researchers and practitioners continue to seek new ways to enhance the quality and quantity of information elicited from interviewees. Our research within this area involves developing new tools and testing existing techniques to enhance information elicitation. We are also exploring ways to advance culturally-sensitive interviewing practices.

2. Cold Case Investigations. We are committed to uncovering the mysteries behind cold cases to advance research and investigative practices. Our research explores the critical questions of Why do cases go cold? and What factors impact the solvability of a cold case? We examine the procedural, resource-related, and evidentiary factors that lead to stalled investigations. Additionally, we study what prompts cases to be reopened, focusing on technological advancements, shifts in investigative priorities, and the impact of new evidence or insights. Our work also delves into the factors that influence the solvability of cold cases, aiming to identify best practices for investigators and highlight strategies to enhance case outcomes. By bridging academic research and real-world application, we strive to support law enforcement and contribute to justice for victims and their families.

3. Advancing Legal Literacy: Protecting Adults and Youth During Police Interrogations. Comprehension of legal rights is an applied problem that spans across social, cognitive, and developmental psychology. When arrested by the police, adults and youth are afforded a set of legal rights (e.g., Right to Silence, Right to Legal Counsel). It is essential that detainees comprehend these rights so they are able to exercise them and make informed decisions during their interactions with police.
