Research interests

Glenn Hartelius’ research focuses on development of constructs and processes that are key to transpersonal psychology. Based on an analysis of literature, his research with colleagues (Hartelius et al., 2022) identified states of consciousness as the central construct of the transpersonal area, yet the scientific study of these states has been hampered by limits in how reliably they can be measured. Glenn uses the more current term, global cognitive states, and has pioneered a method for describing and measuring meditative states based on the associated attentional stance—an advance that offers many new opportunities for research on transpersonal phenomena such as meditation. His most recent paper uses empirical methods to identify the attentional stances likely associated with vipaśyanā and śamatha, two states associated with the Buddhist practice of mindfulness. Glenn is also part of a team that has received funding from the Canadian government for the study of psychedelic therapies utilizing ketamine and psilocybin with First Nations communities, with treatment to be applied not in medical clinics, but in the context of community, culture, and ceremony.
