A term sometimes used synonymously with arousal. It refers to the vigour, vitality, and intensity with which the mind functions. It can be either positive or negative. When performers go from low to high levels of psychic energy they are said to become psyched-up; while those who go from high to low levels are psyched-out. As in arousal, there is an optimum level of psychic energy. See also inverted-U hypothesis.
