Abstract : Subjects were required to decide whether or not a briefly presented picture of a common object was the same as a specified alternative. The alternative was presented either before the stimulus exposure or after it. In experiment 1 the alternative was either the picture of an object or the name of an object. In experiment 2 the subjects were shown all of the stimulus pictures, for 10 seconds each, 24 hours prior to the experimental session. During the experimental session, the subjects were presented with name alternatives either before or after the stimulus flash. Results are discussed with regard to the questions of the nature and locus of the effect of set on tachistoscopic recognition.
