All attempts to test people’s ESP abilities overlook the fact that ESP is an undeveloped function, so we have to learn how to use it to begin with, not just see how much ESP we can show. Psychologist Charles T. Tart applies basic principles of learning to this task to show how training under conditions of immediate feedback can enhance ESP ability. This highly readable book, originally published by the University of Chicago Press, is the theory and a comprehensive study suggesting the principles can work.
Charles T. Tart was an American psychologist and parapsychologist known for his psychological work on the nature of consciousness (particularly altered states of consciousness), as one of the founders of the field of transpersonal psychology, and for his research in parapsychology.
read this because I knew the author. it's a dry subject, mostly about specific studies and ideas for further study. not a self help book. you won't suddenly develop telekinesis by reading this. oh well... :-) but if you're looking to improve learning models related to psi this might be up your alley.
