Tachypsychia (Paperback)

High Quality Content by WIKIPEDIA articles! Tachypsychia is a neurological condition that alters the perception of time, usually induced by physical exertion, drug use, or a traumatic event. It is sometimes incorrectly referred to by martial arts instructors and self defense experts as the Tachy Psyche effect. For someone affected by tachypsychia, time perceived by the individual either lengthens, making events appear to slow down, or contracts, objects appearing as moving in a speeding blur. It is believed that tachypsychia is induced by a combination of high levels of dopamine and norepinephrine, usually during periods of great physical stress and/or in violent confrontation.
