Unconscious self-evaluation using a stereoscope.

"Each subject was presented with his own photograph in a stereoscope, together with that of a stranger, so that a single composite face was seen… . subjects who did not recognize themselves under these conditions were then asked to rate this self-composite for degree of attractiveness, and each subject's rating was compared with one that he made on a control composite consisting of two strange faces. Confirmation was obtained for the hypothesis that the self-composite would be rated higher than the control, thus lending support for the theory of the favorableness of unconscious self-judgments."
