Order Effects in Concomitant Attribute Judgments (Shape and Size)

Abstract

This experiment was designed to determine whether judgment of one stimulus attribute would exert an influence on the judgment of a second attribute as a function of the relative phenomenal strength of the two attributes. One group of Ss was instructed to judge the apparent shape of a Necker cube and then to judge the apparent relative size of its two faces. Another group made the size-judgment first, then the shape-judgment. For most Ss, the two judgments were not independent and were influenced by which of the attributes was judged first.
