J. B. Rhine Father of Modern Parapsychology Conducted experiments at Duke University using Zener Cards to show ESP exists.

Zener Cards Circle Cross Wavy lines Square Star Deck of 25 cards that had one of five symbols on the cards The symbols are Circle Cross Wavy lines Square Star

ESP Not Considered Science Why? No repeatable experimental evidence No tools to measure ESP No biological explanation Rather, ESP considered pseudoscience

Rhine Experiment

Do some people have mental powers beyond the 5 senses?

Experimental Procedures Work in groups of 3. One student will be the “transmitter”, one the “receiver”, & one the “recorder”. The Transmitter will attempt to mentally send the image on to the Receiver The Receiver says what image they receive Receiver does NOT see the cards at any time!!!!! Recorder writes down whether Receiver is correct or incorrect on the Receiver’s lab paper Continue until 15 images have been transmitted Switch roles until each student has a turn as the Receiver DATA 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
