Studies in Visual Perception of Architectural Spaces and Rooms

Judgments of depth and size of space were obtained by the magnitude estimation method under (i) binocular viewing of actual spaces, (ii) monocular viewing of colour photographs, (iii) monocular viewing of detailed drawings, and (iv) monocular viewing of undetailed drawings. Judged depth and size were found to be power functions of the physical measures. The exponents decreased successively under conditions (i)‐(iv). Judged size (rectangular area) might be a power function of judged depth times perceived width. The hypothesis was substantiated that perceived size of space depends on perceived depth.
