An expert in the polygraph and biocommunication, Cleve Backster related details of his research into electrical responses in plant life. His studies indicate that plants can sense human intent in a kind of "primary perception" that he compared to ESP. For instance, in experiments with bean sprouts --one group of sprouts was praised, the second group ignored, and the third sent negative thoughts-- the praised group grew much faster, he reported.
An experimenter can influence the results of a study. The studies which showed plants preferred classical music might've been the result of experimenter bias against rock music, he said. Backster's first plant experiment took place in 1966, and he's now spent over 40 years on this type of research, which he conducts out of a former DEA lab in San Diego, in an under-funded fashion.
He also discussed his work with the polygraph, and noted that newer polygraph equipment incorporates the use of a camera in its readouts.
Cleve Backster is the founder of the Backster Research Foundation and currently teaches at the Backster School of Lie-Detection. He is also on the teaching faculty at the California Institute for Human Science and serves on the advisory board at the Institute of HeartMath.
Cleve is an international speaker on the subject of Biocommunication and has been a professional observer of human psycho-physiological tracings since 1948. Since 1966, Cleve has conducted extensive research related to observed electrical responses in plant life and at a cellular level in other living organisms. His research into what has been called "The Backster Effect" has attracted world-wide attention.
