Extra-sensory Perception

Extra-sensory perception, or ESP, is an alleged ability to acquire information by means other than the known senses, eg. taste, sight, touch, smell, hearing, balance and proprioception. The term implies sources of information unknown to science.

Specific types of extra-sensory perception include Perception of events in other places (clairvoyance, clairaudience, clairgustance, clairsentience) and at other times (precognition, retrocognition, second sight).

Perception of aspects of others not perceivable by most people (aura reading).

The ability to sense communications from, and communicate with, people far away (telepathy), beyond the grave (mediumship, séancing, and spirit walking), or in other dimensions (astral projection).

The study of these abilities, called parapsychology, includes other phenomena such as psychometry and psychokinesis, which are associated with ESP.

A person capable of using ESP is referred to as a psychic or as having psychic powers.
