A study by Pavlov (5, p. 30) indicated that normally painful stimuli applied while hungry dogs were feeding produced less overall avoidance behavior than at times when they were not feeding. In a still earlier study, Jones (3) reported that extinction of avoidance to a feared stimulus was hastened by gradually introducing the stimulus while the child subject was eating. More recently, Farber (1) has presented evidence that feeding in the presence of anxiety-producing cues hastened later extinction to those cues as compared to control animals which did not receive the feeding experience. In Miller's words (4): "Eating and the emotional responses that accompany it are apparently incompatible with fear, and the attaching of these responses to the stimuli that arouse the fear suppresses it."
