Welcome to ZENER, the original ESP Test.
This is the extrasensory perception test, excactly as it was originally invented and conducted by the perceptual psychologist Karl Zener in the early 1930s.
▶The test:
Open Zener and browse between a deck of cards made up of five simple symbols:
◆ A hollow circle
◆ A Greek cross
◆ Three vertical wavy lines
◆ A hollow square
◆ A hollow five-pointed star
The person conducting the test (sender) freely chooses a card and concentrates on its symbol. The person being tested for extrasensory perception (receiver) tries to determine which card he/she has selected.
