A phenomenon related to the study of perception and well known in the popular domain is called extrasensory perception (ESP). The belief is that one can have a perceptual experience without any sensory input. Types of reported ESPs include mental telepathy, the ability to read another person's thoughts forecasting, the ability to predict future incidents accurately (for example, who will win a race or engage in a particular activity) clairvoyance, the awareness of some event that one cannot see (for example, knowing where a body is hidden) psychokinesis, the ability to cause things to move by virtue of thought processes Psychologists known as parapsychologists study these phenomena, but the majority of psychologists feel that evidence for the existence of ESP phenomena has not been adequately documented.
