Abstract
Thirty-four male Ss made size and distance estimates of an after-image observed with closed eyes. Size estimates showed small variability, but distance estimates were highly inconsistent. To account for the consistent size estimates it is tentatively proposed that although the subjective impression is of boundless space, with eyes closed the sensory system acts as if the eyes are fixated at a finite rather than infinite distance.
