A configuration looking like a cross of a black rectangle and a white rectangle on a mid-gray background was uniformly illuminated. Illuminance of the total display and the reflectance of the central area were systematically changed. The subjects were asked to judge which one, the black or the white, looked transparent or in front, and to judge the lightness of the central area. It was found that there was a very high correlation between transparency and lightness judgment: when the central arca looked darker, the black appeared transparent, and this relation was reversed in the ease where the central area was rather light. It was further demonstrated that as illuminance was increased, the “white-transparency” became more and more dominant over the “black-transparency” These bindings suggested the importance of the Gestalt law of similarity in the perception of transparency, resulting in mutual assimilation of lightness between a critical area and its neighboring areas. It was discussed, however, that we should not regard perceptual transparency as a consequence of lightness assimilation.
