Abstract: Discusses some recent experimental attempts to provide converging operations for a concept of perceptual defense. For present purposes, perceptual defense is defined as a relative failure of perception per se due to the emotional character of the stimulus. Experiments are evaluated and discussed mainly in terms of their ability to eliminate as an explanation the response-bias hypothesis for differential accuracy between neutral and emotional words. In addition, following Blum, a stimulus-effect hypothesis is described and applied; all the experiments discussed require, if differences in accuracy of recognition are to be attributed to perceptual variation, converging operations to eliminate this hypothesis. It is argued as well that the search for converging operations for perceptual defense has implications for methodology in other areas of perception. (20 ref.)
