Assessed the effects of physiological feedback during actual exposure to a feared situation and during a subsequent exposure. 60 speech-anxious Ss were exposed during the 2nd of 3 consecutive speeches to 1 of 5 false feedback conditions: heart rate decreasing, no change in heart rate, heart rate increasing, and 2 control procedures. No anxiety differences were found among the groups on the 2nd (feedback) speech. The heart-rate-increase group displayed significantly higher self-reported anxiety, overt anxiety signs, and speech disfluencies during the 3rd (posttest) speech than the heart-rate-decrease and no-change groups. Initial exposure to the speech situation produced striking heart-rate reaction in the total group, and repeated exposures continued to elicit strong, though gradually habituating, reactions.
