Believer or skeptic, how methods of spiritual communication came about is an interesting subject. Here we look at beliefs of days gone by and the methods used to protect or communicate.

Quick guide Zener cards

Originally, tests for ESP were conducted using a standard deck of playing cards, now most testing of telepathy and precognition is done using Zener cards or ESP (extra sensory perception) cards. Designed by Dr Karl Zener in the early 1930’s.

Over the years Zener cards have had many incarnations. The early cards were produced onto wafer thin pieces of paper, when it was discovered that receivers were able to identify what was on the cards by looking at the back of them, they were changed so that cheating in this manner wouldn’t happen.

Now they are a circle, a star, three wavy lines, a square and a plus sign. There are 25 cards in a pack, five of each design.

You probably recognize these cards from "Ghostbusters."

At the very beginning of the film, parapsychology professor and ladies man Dr. Peter Venkman uses Zener Cards to test two university students. In a comedy turn, he enrages one volunteer who apparently is more psychically gifted than the other, forcing the student to leave Dr. Venkman alone with the other candidate, an attractive young lady.

O.k. this is how they work, the sender and receiver are separated so there can be no communication other than telepathically. The sender is asked to project the image on the card into the receivers mind. The receiver has to draw or verbally express the first card that pops into their minds. Chance says that the receiver should get a 20 per cent success rate ( 1 out of 5 ), so parapsychologists are looking for a consistent rate, higher than 20 per cent to prove the existence of telepathy.
