Abstract
A MENTAL set, or “expectancy”, may exercise a selective influence on the perception of ambiguous stimuli1. Such a set can be induced by a bodily need such as hunger, or by verbal instructions. The present study investigates whether an instruction which an individual gives to himself has more effect on subsequent perception than an instruction which he receives from an external source. There were three independent groups of subjects.
