Psychic staring effect

The psychic staring effect (sometimes called scopaesthesia) is the claimed extrasensory ability of a person to detect being stared at. The idea was first explored by psychologist Edward B. Titchener in 1898 after students in his junior classes reported being able to "feel" when somebody was looking at them, even though they could not see this person. Titchener performed a series of laboratory experiments that found only negative results. The effect has been the subject of contemporary attention from parapsychologists and other researchers from the 1980s onwards, most notably Rupert Sheldrake.

The feeling is a common one, being reported by over two thirds of the students questioned in a 1913 study.

Origin

Psychologist Edward B. Titchener reported in 1898 that some students in his junior classes believed that they could "feel" when they were being stared at from behind, and a smaller proportion believed that by staring at the back of a person's neck they could force them to turn around. Both phenomena were said to occur in public places such as classrooms and public halls. His students described the feeling as "a state of unpleasant tingling, which gathers in volume and intensity until a movement which shall relieve it becomes inevitable".

Titchener rejected the telepathic explanation. He instead suggested that when a subject experienced the feeling that they were being watched and turned to check, a second person who already had the subject in their field of vision might notice the subject starting to turn their head, and shift their gaze to the subject.
