Michael Anthony Thalbourne (24 March 1955 – 4 May 2010, Adelaide, South Australia) was an Australian psychologist who worked in the field of parapsychology.
His books include: A glossary of terms used in parapsychology (2003),[3][4] The common thread between ESP and PK (2004), and Parapsychology in the Twenty-First Century: Essays on the future of Psychical Research (2005).
In the 1990s he wrote on the concept of transliminality; his early work suggesting that this could be a trait linking such personality variables as belief in the paranormal, creative personality, mystical experience and psychopathology led him to describe this as a "common thread" linking these variables.
Thalbourne also collaborated on empirical research projects with Erlendur Haraldsson,[11] and developed the Australian Sheep-Goat Scale, a measure of the extent to which a person believes in the paranormal.
He published a scale to assess the kundalini experience with the world-renowned expert on panic attacks, Bronwyn Fox.
