Ouija Board The ouija also known as a spirit board or talking board, is a flat board marked with the letters of the alphabet, the numbers 0–9, the words "yes", "no", occasionally "hello" and "goodbye", along with various symbols and graphics. It uses a planchette (small heart-shaped piece of wood or plastic) as a movable indicator to spell out messages during a séance. Participants place their fingers on the planchette, and it is moved about the board to spell out words. "Ouija" is a trademark of Hasbro,[1] but is often used generically to refer to any talking board.
Paranormal and supernatural beliefs associated with Ouija have been criticized by the scientific community and are characterized as pseudoscience. The action of the board can be most easily explained by unconscious movements of those controlling the pointer, a psychophysiological phenomenon known as the ideomotor effect.
