Plant Perception By: Avery Ockman What is it? • Theory that plant’s are sentient • Can perceive and react accordingly to stimuli such as: – Pain – Pleasure – Various emotions ~Plants reaction to music~ History • First documented by Dr. Gustav Theodor Fechner • In his book “Nanna” in 1848 – Plants are capable of emotions, just like humans or animals, and that one could promote healthy growth by showering plants with talk, attention, and affection. Further Reasearch • Sir Jagdish Chandra Bose in 1900 – Found that every part of a plant “appeared” to have a central nervous system and responded to a shock or spasm just as an animal muscle would – One visitor to his laboratory, the vegetarian playwright George Bernard Shaw, was intensely disturbed upon witnessing a demonstration in which a cabbage had violent convulsions as it boiled to death. • Also claimed plants could “feel pain and understand affection” based on potential variations in plants’ cell membrane. “The Backster Affect” • Research by Cleve Backster beginning in 1966. – Used a polygraph to conduct experiments. • Similar electrical patterns to a human emotional stimulus. Fire causing an upward pattern in the plant’s electrical resistance. Results • An overall better understanding of plant’s reactions to the environment. • Communication: – Botanicalls – Pet Plant – Midori-San Skepticism • Lack of concrete evidence. – Technologically impossible to measure. “Pseudoscience is a methodology, belief, or practice that is claimed to be scientific, or that is made to appear to be scientific, but which does not adhere to an appropriate scientific methodology.” Related Theories • Gaia Theory – Components of Earth are integrated to form an interacting system. • Earth as a single organism. – “A complex entity involving the Earth's biosphere, atmosphere, oceans, and soil; the totality constituting a feedback or cybernetic system which seeks an optimal physical and chemical environment for life on this planet. • Parapsychology – Investigating paranormal using the scientific method.
