Effects of False Feedback on Pain Tolerability Among Young Healthy Adults: Predictive Roles of Intentional Effort Investment and Perceived Pain Intensity.

Expectations and modification gained through critical learning influence pain perception. We tested how pain tolerability was influenced by the effects of orally delivered false feedback and participant status immediately prior to performing tasks. A total of 125 healthy college students (69 females and 56 males) were randomly assigned to 3 groups (positive, negative, and control) to participate in two formal cold pressor tests (CPTs). Participants completed the same series of task-related questionnaires (perceived importance, intended effort, current affect, and self-efficacy) before each CPT. False performance feedback was delivered after completion of the baseline level CPT. After completion of each CPT, both pain intensity and pain tolerability (duration in ice water) were recorded. The results of linear mixed models revealed significant condition × time interactions on pain tolerability and task self-efficacy after controlling for individual variance as a random effect. Participants who received negative feedback exhibited increased pain tolerability without decreasing their self-efficacy, whereas participants who received positive feedback showed increased self-efficacy with no change in pain tolerability. A longer pain tolerance duration was also predicted by a more intentional investment of effort and a lower intensity of experienced pain as well as the effect of false feedback. The research highlights the effect of powerful situational influences on laboratory-induced pain tolerance.

Effects of False Feedback on Affect, Cognition, Behavior, and Postevent Processing: The Mediating Role of Self-Focused Attention

Current social phobia models (e.g., Clark & Wells, 1995; Leary & Kowalski, 1995) postulate that socially anxious individuals negatively appraise their anxiety sensations (e.g., sweating, heart racing, blushing) as evidence of poor social performance, and thus fear these anxiety symptoms will be noticed and judged negatively by others. Consequently, they become self-focused and hypervigilant of these sensations and use them to judge how they appear to others. To test this model, high (N=41) and low (N=38) socially anxious participants were shown false physiological feedback regarding an increase or decrease in heart rate prior to and during an impromptu speech task. Relative to participants who observed a false heart rate decrease, those in the increase condition reported higher levels of negative affect, more negative performance appraisals, and more frequent negative ruminative thoughts, and these effects were mediated by an increase in self-focused attention. The unhelpful effects of the physiological feedback were not specific to high socially anxious participants. The results have implications for current cognitive models as well as the treatment of social phobia.

Perception of arousal in social anxiety: Effects of false feedback during a social interaction

Cognitive models suggest that during social interactions, socially anxious individuals direct their attention to internal cues of arousal and use this information to erroneously infer how they appear to others. High (N=36) and low (N=36) socially anxious adults had a conversation with a stooge, and were led to believe by false feedback that they were experiencing either an increase or decrease in arousal, or evaluating the comfort level of the feedback equipment. Compared to the other groups, participants who believed their arousal had increased, reported greater anxiety, poorer perceived performance, more physical cues of anxiety, and greater underestimation of their performance and overestimation of the visibility of their anxiety. The effects were not specific to participants with high social anxiety. Observers rated the behaviour of participants who believed that their arousal had decreased most favourably. The results have implications for the treatment of social phobia.

Biofeedback training of relaxation: The effects of false feedback and the influence of suggestibility

The effect of contingent and non-contingent (false) biofeedback upon heart rate (HR) and subjective reports of relaxation was investigated, and the role played by suggestibility as an individual difference was examined. There were four experimental groups. One received true contingent HR biofeedback and another received no feedback at all. There were also two non-contingent groups. One received false information suggesting that HR was going down and one group received information suggesting that HR was going up. Ss' level of suggestibility was also assessed. Comparisons between the feedback conditions and the no feedback group confirmed the efficacy of biofeedback in relation to the reduction of HR. However, non-contingent feedback was found to be as effective as contingent feedback in HR reduction. Suggestibility as an individual difference was not found to be related to HR reduction but did play a complex role in the subjective report of relaxation. Results are discussed emphasising the non-specific component of the biofeedback paradigm and thus questioning the operant-conditioning model.

The effects of false feedback on attributed arousal and rated attractiveness in female subjects1

AbstractIn an expanded version of the Valins false feedback paradigm, female subjects viewed ten slides of seminude males accompanied by either an increase or no change in amplified heart beats. Heart rate increase slides were rated as both more attractive and more arousing than no‐change slides. These two measures were highly correlated, and did not differ significantly in the degree to which they were influenced by feedback. Subjects also showed significantly greater changes in actual heart rate for the increasing feedback slides than for the no‐change slides, although the feedback produced no corresponding differences in GSR. Despite the effects on both subjective report and cardiac activity, correlations between these two measures were generally nonsignificant. Subjects classified as high in autonomic perception showed no significant relationship between actual cardiac activity and slide ratings, nor were they more influenced in their ratings by the feedback than subjects low in autonomic perception. Implications for the false feedback paradigm and for current issues in the social psychology and psychophysiology of emotion are discussed.

Effects of false feedback about response lengths of subjects perception of an interview.

Summary Sixty-four female freshmen were interviewed about various attitudes toward their college. Halfway through the interview, three groups of subjects were told falsely by the experimenter that their responses to the questions had been significantly longer than average, of about average length, or significantly shorter than average. A fourth group of subjects was given no false feedback. Subjects with longer than average false feedback increased their response lengths significantly during the last half of the interview and rated the interview questions significantly more favorably than other subjects. Subjects with shorter than average false feedback also gave significantly longer responses during the second half of the interview, but did not differ from average false feedback and no feedback subjects in their favorability toward the interview questions. Results of the study were discussed in terms of Bem's self-perception theory.
