David Yaden

David B. Yaden, PhD, studies the measurement and experimental manipulation of mental states called altered states of consciousness. These mental states are often among the most transformative and meaningful moments in people’s lives, yet little is known about how they are triggered, the neurophysiological processes that underlie them, or how they impact the beliefs and behavior of those who have them. His research is currently focused on the therapeutic potential of psychedelic substances for mood and substance use disorders. His scientific research and scholarly writing generally aim to provide a quantitative and empirical 21st-century update to William James’s classic book on the topic, The Varieties of Religious Experience, using: 1) psychometric instruments, 2) computational linguistic analysis, 3) neuroimaging, 4) non-invasive brain stimulation, and 5) psychopharmacology. Psychopharmacologist Roland R. Griffiths, PhD is his previous Postdoctoral advisor. He previously studied with neuroscientist Andrew B. Newberg, MD and completed his doctoral training with psychologist Martin E. P. Seligman, PhD at the University of Pennsylvania. He has authored over 40 scientific and scholarly publications and edited two books that provide a scientific perspective on practices and experiences traditionally associated with religion/spirituality: Rituals and Practices in World Religions and Being Called. His research has been covered by The New York Times, The Wall Street Journal, The Washington Post, New York Magazine, Scientific American, CNN, BBC, and NPR.
