“…Although a number of studies have demonstrated convincingly that familiar size influences adult subjects' judgments of object distance (Baird, 1963;Dinnerstein, 1967;Epstein, 1963Epstein, , 1965Epstein & Baratz, 1964;Eriksson & Zetterberg, 1975;Fitzpatrick, Pasnak, & Tyer, 1982;Gogel, 1968Gogel, , 1969Gogel & Mertens, 1968;Ittelson, 1951aIttelson, , 1951bNewman, 1972;Ono, 1969), one important criticism of these studies has not been adequately addressed. In a critique of Ittelson's (1951a) study, Hochberg and Hochberg (1953) argued that Ittleson's subjects might not have perceived the stimulus objects to be at the distances they reported; instead, they may have consciously inferred the distances at which familiar objects would project various visual angles. Thus, it is unclear whether familiar size determines perceived distance or only allows subjects to make conscious estimates of distance.…”
