Terms used to describe phenomena witnessed in psi testing. The decline effect is a term used to describe the diminishing of psychic ability when tested. The incline effect refers to an increase in ability.

Experiments to test psychic ability tend to show that the decline effect occurs more often than the incline effect. Some gifted individuals score highly consistently but many gifted test subjects, who have scored highly in the initial tests, report a loss of spontaneity and enthusiasm during a run of tests. This may be due to the fact that the perception of psi is a very subtle process and without feedback a subject has no way of judging his or her success. Another major factor is boredom as many tests involve repetitive tasks such as guessing numbers or cards.
