Extrasensory perception

Extrasensory perception (more commonly abbreviated as ESP) is a term which is applied to the human ability to perform activities that utilise more advanced sensing abilities than are provided by the basic five senses. For centuries many scientists believed that humans ESP abilities were always going to be limited by the brain, however it had been proved that basic ESP abilities could allow someone to predict future events, start fires spontaneously and see through objects.

By the 23rd century, Starfleet recorded an officers ESP ability as part of their routine medical and pshychological evaluations. (TOS episode: "Where No Man Has Gone Before").
