Jamie I. D. Campbell (1952-2022)

Jamie Campbell, professor emeritus at the University of Saskatchewan, passed away September 12, 2022. After a few years on the road as keyboard player in a rock group, Jamie received his B.A. from Queen’s University (1979) and Ph.D. from the University of Waterloo (1985). His Ph.D. work on arithmetic (Campbell, 1987) set a standard for comprehensive and detailed experimentation in the emerging field of numerical cognition. Subsequently, he completed a postdoc at Carnegie Mellon University, followed by an appointment at the University of Western Ontario. In 1990, Jamie moved to the University of Saskatchewan where he remained until his retirement in 2021. Jamie published many empirical papers that combined methodological rigour with a concern for conceptual replication. He also made important theoretical contributions. For example, his seminal work on the architectures of numerical cognition (Campbell, 1994) greatly influenced theorizing in the field. The encoding-complex view of numerical cognition (Campbell & Clark, 1988; Campbell & Epp, 2004), the network-interference theory of arithmetic (Campbell, 1995), research on cognitive arithmetic across cultures (Campbell & Xue, 2001), and work on retrieval-induced forgetting in arithmetic (e.g., Campbell & Thompson, 2012) will continue to influence research into the future. Most recently, his work was focussed on procedural versus retrieval solutions for arithmetic problems (Campbell et al., 2021; Chen & Campbell, 2019). Jamie was a gifted teacher, mentor, and colleague. He was unfailingly generous with his time. He regularly attended and presented at conferences, especially Psychonomics, and the Canadian Society for Brain, Behaviour and Cognitive Science (CSBBCS). The mathematical cognition community broadly, and especially those of us within Canada, will greatly miss his insightful contributions, dry humour, and warm presence. He is survived by his life-partner, Professor Valerie Thompson.
