How comparison stimulus display position affects relative size perception with the method of transposition

Abstract

  The “Method of Transposition” proposed by Oyama does not affect the target objects and can measure the relative apparent sizes of target objects. Using the method of transposition to compare how comparison stimulus display position affects relative apparent size has not been investigated.  In this paper, the relative apparent sizes of two spheres are measured using CGI as a comparison stimulus displayed on a notebook computer at two different viewing distances (50cm and 100cm). It was found that there is no statistical difference between the relative apparent sizes measured at the two different viewing distances.
