Abstract

2 experiments are reported testing a hypothesis that choice preference is a function of complexity of both stimuli and the individual, and that “the individual's complexity increases as he has perceptual commerce with stimuli which have measures of complexity exceeding his own momentary measure by an appropriate amount.” Using pigmented rats and contiguous circular pathways differing in complexity of black-white patterns, it was shown, as predicted, that preference shifted toward the stimulus of greater complexity. “It is argued that these results cannot be explained by theories which are based solely on concepts of satiation or avoidance.” (PsycINFO Database Record (c) 2006 APA, all rights reserved)
