Trends in the Study of Out-of-Body Experiences: An Overview of Developments Since the Nineteenth Century
Carlos S. Alvarado, Institute for Parapsychology, Box 6847, College
Station, Durham, NC 27708
A review of conceptual and research trends in the literature on out-of-body
experiences is presented to the period of mid-nineteenth century to
1987. The discussion emphasizes psychological, psychiatric, and parapsychological
publications. The material shows recurrent topics, but there are also
some differences, particularly regarding more detailed conceptual discussions
and a higher frequency of research projects in recent times. Systematic
research and testable theories have been presented mainly in the last
two decades. This may be related to the revival of interest in cognitive
variables and altered states of consciousness in psychology during the
same time period.
