To investigate how quickly we can perceive being watched by other people, we evaluated the effect of duration on the quantitative judgment of gaze direction and the perception of "being looked at". The stimuli were models of heads generated by a computer, and the rotation angle and gaze direction of each head was varied independently. The participants were asked to judge whether the stimulus was looking at them (being-looked-at judgment), and to judge where the stimulus was looking (quantitative gaze direction judgment). The results revealed that neither the direction that gives the best perception of being-looked-at, nor the perceptually straight direction of the participants were affected by the duration (100ms, 1000ms, or an unlimited duration). These results indicate that the judgment of whether or not a looker's gaze is directed towards one completes at an early level in the gaze perception process and within 100ms.
