D. Stephen Lindsay is a cognitive psychologist in the field of memory, and a professor of psychology at the University of Victoria (UVic), British Columbia.
Lindsay became a faculty member at UVic in 1991, previously teaching at Williams College and completing a post-doctoral fellowship with Larry Jacoby at McMaster University.
In his dissertation he initially set out to investigate the impact of imagining contrary-to-truth hiding places on children's memory for the actual spatial location of objects.
He became interested in Johnson's ongoing work on reality monitoring (the process of distinguishing between memories of external, physically experienced events versus those originating from internal sources such as imagination and thought).
[6] This led to work on the broader issues of source monitoring - how people decide where a given memory comes from, whether from own experience, a television broadcast, a story told by a friend etc.
