It is presently unresolved whether lightness or differences in lightness are appropriate independent variables for models of perceived achromatic transparency. This experiment shows the differences in lightness rather than lightnesses affected the rated transparency and that local changes in difference in lightness altered the rated transparency locally. These results indicate that models of the perceived degree of transparency should be separately formulated for the different parts of a transparent surface and for the whole transparent surface. Two new models of the combined effecs of lightness differences on the perceived transparency are proposed.

Abstract
It is presently unresolved whether lightness or differences in lightness are appropriate independent variables for models of perceived achromatic transparency. This experiment shows the differences in lightness rather than lightnesses affected the rated transparency and that local changes in difference in lightness altered the rated transparency locally. These results indicate that models of the perceived degree of transparency should be separately formulated for the different parts of a transparent surface and for the whole transparent surface. Two new models of the combined effecs of lightness differences on the perceived transparency are proposed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
