In the 1930's, J. B. Rhine and Karl Zener from the Duke University Psychology Department designed a deck of 25 cards to test for ESP. The deck consisted of five cards of each symbol: Star, Circle, Wave, Square, and Cross. This on-line test uses only 10 cards created using a random number generator.

Since there are only 5 different symbols, the chance of guessing any one card is 1/5 (20%). On average, you should be able to guess two symbols for the 10 cards displayed. The significance level is calculated using a two-tailed statistical t Test. The term "not significant" means that the results do not differ substantially from what would be expected by chance.
