Is Scopaesthesia a Real Phenomenon? An Experimental Investigation of the Ability to Detect an Unseen Gaze

Scopaesthesia, the ability to detect an unseen gaze, is claimed by some researchers to be a real phenomenon, potentially challenging conventional models of visual perception. The present study aimed to test this experimentally by assessing whether 20 participants could determine if they were being watched from behind across 20 randomized trials each. Three hypotheses were tested: one examining the participants´ ability to indicate better than chance whether they were being observed or not, one based on difference in accuracy depending on being observed or not, and one based on the blindfolding of participants. The results of the hypothesis tests did not support scopaesthesia as a real phenomenon, and the study therefore does not challenge the prevailing explanations of visual perception.
