Opportunity for information search and the effect of false heart rate feedback

The role of information search in the attribution of physiological states was investigated by manipulating the subject’s opportunity for information search following the presentation of false information about his heart-rate reactions to photographs of female nudes. Consistent with the self-persuasion hypothesis proposed by Valins, the rated attractiveness of the slides was not affected by the false heart-rate feedback for those subjects who were prevented from visually searching the slides. Those subjects who had ample opportunity to view the slides rated those slides accompanied by false information of a heart-rate change as more attractive than those slides which were not paired with a change in heart rate.     

Effects of false heart rate feedback and task instructions on information search,attributions, and stimulus ratings

Summary Predictions derived from an information seeking, attribution model of false autonomic feedback were tested in an experiment using a 3 × 3 design. Male students (n = 61) viewed aversive slides accompanied by either increasing, constant, or no heart sounds. They were instructed either to attend to slides and sounds labelled extraneous, or to slides and sounds labelled as their own heart beats, or to try to explain their fictitious heart beats through slide features (attribution condition). Increase and constant feedback instigated equally intense information search (measured through self-determined viewing time and heart-rate deceleration) but increased feedback did not direct the search (measured through viewing time distribution and recall) more towards negative or less towards neutral features than did constant feedback. Increased feedback enhanced rated slide unpleasantness in the attention and attribution conditions whereas constant feedback decreased unpleasantness in the attribution condition only. Correlations were consistent with the hypothesis that attributions of fictitious autonomic reactions, but not information search and actual heart rate, mediate feedback effects on stimulus valences.The author would like to thank Paul Wagemann, who ran part of the subjects, Alfred Holl, who helped to cope with equipment problems, and Günter Eisenhut, who assisted in data reduction and analysis.     

False autonomic feedback: Effects of attention to feedback on ratings of erotic stimuli

This study examines the roles played by sound track type, attention to sound track, and meaning of sound track in mediating the effects of false autonomic feedback on attractiveness ratings of erotic stimuli. Male subjects were instructed either to ignore or to pay attention to a pulsed or continuous sound track that was described either as heart-rate feedback or as a neutral auditory stimulus while slides of nude females were shown. Slides associated with a change in either the pulsed sound track or the continuous-tone sound track (increase slides) were subsequently rated as significantly more attractive than those associated with steady sound (stable slides). This effect was contingent on the meaning given to the auditory stimuli, with subjects in the heart-rate condition showing a stronger tendency to rate increase slides more positively than stable slides, by comparison with subjects in the neutral sounds condition. Within the heart-rate condition, subjects told to pay attention to the feedback showed greater rating differences between these two types of slide than those told to ignore it. This pattern of findings contrasts with those of an earlier experiment (Parkinson & Manstead, 1981), where differential unpleasantness ratings of slides of skin diseases depended on the attention paid to the sound track but not on its meaning. It is concluded that the effects of false autonomic feedback are contingent upon the kind of emotional stimuli that are presented.This article is based on research supported by the Economic and Social Research Council (UK).

Persistent effects of information about internal reactions: Ineffectiveness of debriefing

A process of self-persuasion has been advanced to account for the effects of information about internal reactions on attitudes toward emotional stimuli. To determine whether the results of this cognitive activity would be resistant to debriefing, Ss were shown slides of female nudes while hearing their alleged heart-rate reactions and were subsequently informed that these reactions were part of a deception manipulation. It was found that, although Ss accepted the debriefing, the false information continued to exert an infleunce on their attitudes toward the nudes. The attitudes of these Ss toward the nudes were the same as those of Ss who were not debriefed.

Information need,affect, and cognition of autonomic activity

Several studies have shown that bogus feedback of physiological change induces a greater liking for attractive stimuli. Other research suggests that the affective change induced by bogus feedback requires an opportunity to visually search change-associated stimuli for information which can account for its purported physiological effect. While there is considerable agreement among theorists that a greater disliking should obtain when the stimuli are unattractive (but a lack of data supporting this contention), there is disagreement about whether information searching is directed equally toward change-associated stimuli and no-change stimuli, or toward change-associated stimuli alone.Results of the present study support the contention that stimulus features determine the kind of affect experienced: change-associated slides depicting nudes are rated as more attractive than no-change-associated nudes, and change-associated slides depicting accident vitctims are rated as more repulsive than no-change-associated victims. Information seeking data are more consistent with the contention that information needs exist after both types of feedback.     

False physiological feedback and emotion: Experimenter demand and salience effects

Four experiments examined the hypothesis that the Valins (1966) false physiological feedback effect with attractiveness ratings of slides is due to experimenter demand. Experiments 1 and 2 showed significant feedback effects with 5-sec feedback periods, previously reported by Barefoot and Straub (1971) to be too brief a time to search the slides for a cause of the apparent physiological arousal. Experiments 3 and 4 had 17 variations of instructions (emotional, nonemotional), stimuli (slides of people, scenic tourist slides), and type of feedback information (heart rate, eyeblink, or none). The typical false feedback effect was found under many conditions that did not seem to meet the presumptive attributional requirements for the effect. In Experiment 4, only subjects who said they were supposed to rate feedback slides higher showed the effect, regardless of instructions, stimuli, or type of feedback. The overall results are interpreted in terms of experimenter demand and stimulus salience effects.     

Exposure to pornography,permissive and nonpermissive cues,and male aggression toward females

The present study examined the role of permissive and nonpermissive cues in mediating the relationship between exposure to erotica and aggression. Male subjects viewed either neutral slides with a silent female or erotic slides with a female who made permissive, nonpermissive, or no comments about the slides. The males rated the slides and subsequently rated the female confederate. Male subjects were then given an opportunity to administer their choice of several intensities of shock to the female in a competitive reaction-time task. Subjects in the permissive cues condition rated the erotic slides as more arousing, saw the female as more reasonable and accepting, and selected more intense shocks for the female than did subjects in the other conditions. One explanation of these results is that permissive cues in the presence of erotica led the male to believe that other normally inappropriate behaviors would be tolerated.     

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

In 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.     

The role of perceived physiological activity in affective judgments

This study assessed the physiological and cognitive effects of Valins' (Valins, S. Journal of Personality and Social Psychology, 1966, 4, 400–408) false heart rate procedure. Twenty-two male subjects were exposed to two feedback conditions during which measures of actual heart rate and skin conductance were obtained. In each condition, eight slides of nude females were presented; some slides were associated with false heart rate increases, while for other slides the feedback remained stable. In one condition, subjects were told that the heart rate was that of another subject; in the other condition, subjects were told that the feedback was their own heart rate. In both conditions, subjects judged the attractiveness of the slides from their own point of view and from the point of view of the other subject. Slides associated with false heart rate increases were rated as more attractive than stable slides when subjects (1) heard their own heart rate and rated their own attraction; (2) heard the other subject's heart rate and rated their own attraction; and (3) heard the other subject's heart rate and rated the other subject's attraction. Skin conductance responses and actual cardiac decelerations were greater when subjects heard what was allegedly their own heart rate and when the slides were accompanied by apparent cardiac acceleration. However, these actual physiological responses did not play a causal role in relation to the affective judgments. Instead, the relationship between perceived physiological changes and feelings of attractiveness was mediated by cognitive processes associated with informational and directive influences of the feedback.     

The relationship between arousal and positive self-presentation

Investigated the validity of the hypothesis that subjects would experience arousal if they received information suggesting that they were presenting themselves to others in a negative manner. Twenty-seven subjects were randomly assigned to a control, evaluation apprehension, or negative feedback group. Subjects' heart-rate was continuously monitored as subjects' rated a series of photographs. Subjects in the evaluation apprehension group were given a cue as to how to present themselves positively whereas subjects in the negative feedback group were told, following their response to the 15th photograph, that their responses suggested maladjustment. Heart-rate change above a baseline measure revealed that an increase in heart-rate occurred only when subjects were informed that they were transmitting negative information. Such a finding supports a positive self-presentation explanation of subject motives in the psychological experiment.     

Arousal transfer: The influence of fear arousal on subsequent sexual arousal for subjects with high and low sex guilt

Male subjects (N = 128) with high or low sex guilt either were or were not threatened with shock (fear arousal manipulation) and then viewed either an erotic or a neutral film (sex arousal manipulation). Then all subjects viewed and rated slides of attractive women and slides of landscapes (neutral control slides). If fear arousal was specifically transferred to sexual arousal as is often predicted rather than simply causing a general increase in arousal, then it would be expected that subjects who had been exposed to the threat would show high arousal in response to the slides of women and low arousal to the slides of landscapes, whereas subjects who had not been threatened would show low arousal to both the slides of women and landscapes. Physiological (pulse rate, skin resistance), self-report, and word association measures consistently indicated that (a) both of the arousal manipulations were effective, (b) the slides of women were arousing, (c) sex guilt influenced responses as would be expected from previous research, but (d) did not indicate support for arousal transference. These findings (a) provide information concerning the influence of guilt on drives, (b) raise questions about the transfer of arousal that was noted in less controlled investigations, and (c) highlight the need for additional controls in research of this type.     

The actions of others as determinants of behavior in social trap situations

Three studies were conducted to determine the effects of observing the behaviors of others upon an individual's actions in a simulated social trap situation. In Experiment 1, it was found that merely having the opportunity to make comparative appraisals of the actions of others led to greater competition for a finite common resource than when subjects were physically isolated from one another. In Experiment 2, false feedback was given to subjects to determine if the actions of others alone were responsible for the deleterious effects of having the opportunity for comparative appraisal; it was found that subjects quickly conformed to the behavior pattern of the interacting others, regardless of whether the false feedback indicated that the other subjects were consuming more or less than no-treatment control subjects. Experiment 3 was conducted to determine the motivation of subjects reacting to the actions of others; differential predictions based upon a competition/relative outcome explanation and upon an information search explanation were made. The data were consistent with the information search explanation.     

Active search,mediation, and the manipulation of cue dimensions: Emotion attribution in the false feedback paradigm

The present experiments investigated the mechanism(s) that produce the false feedback effect. Although the present studies replicated the basic phenomenon, previously proposed mediators of attention and arousal did not appear related to the effects obtained. In Experiment 1, change feedback slides were rated significantly higher than no-change feedback slides (F(1, 39)=11.88,p<.01). Correlations showed that both arousal and nonarousal feedback cues produced active search and influenced stimulus ratings. Attention or arousal differences between change and no-change feedback should not result in equal cue effects. In Experiment 2, feedback rating differences were eliminated by presenting less differentially ambiguous situational stimuli. These findings suggested that important factors in the emotion attribution process may be the relative ambiguity and subjective salience of both situational and physiological cues.     

Relative contributions of expressive behavior and contextual information to the judgment of the emotional state of another

This study used a technique for assessing the relative impact of facial-gestural expressions, as opposed to contextual information regarding the elicitor and situation, on the judgment of emotion. In Study 1, 28 undergraduates rated videotapes of spontaneous facial-gestural expressions and separately rated the emotionally loaded color slides that elicited those expressions. The source clarities of the expressions and slides were matched using correlation and distance measures, and 18 expressions and 9 slides were selected. In Study 2, 72 undergraduate receivers were shown systematic pairings of these expressions and slides and rated the emotional state of the expresser, who was supposedly watching that slide under public or private situational conditions. Expressions were found to be more important sources for all emotion judgments. For female receivers slides were relatively more important in the public than in the private situation.     

False memories and source‐monitoring problems: criterion differences

A source‐monitoring/memory suggestion experiment was used to produce false memories and a signal‐detection analysis was conducted to determine if criterion differences could help explain their production. The procedure and stimuli were adapted from Zaragoza and Lane ( 1994 ). Participants saw slides depicting a crime and then answered questions about the slides with some of the questions containing suggested or misleading information. After a brief delay filled with several assessment tests, a list of items was presented and the participants were asked to identify whether each item came from the slides, the questions, both or neither. The results showed that all participants produced false memories but those who adopted more lenient criteria produced more false memories. In addition, those with stricter criteria scored lower on an assessment of dissociative experiences. These results were interpreted within a source‐monitoring framework.

Receipt of a False Positive Test Result During Routine Screening for Ovarian Cancer: A Teachable Moment?

The term "teachable moment" (TM) has been used to describe a life transition or event which motivates an individual to change a behavior or presents an opportunity to intervene to prompt behavior change. We examined whether receipt of a false positive ovarian cancer (OC) screening result may represent a TM. 403 women participating in an OC screening program completed questionnaires assessing demographic, clinical, behavioral, and psychosocial information. The TM was operationalized as expressed interest in receiving health-related information. We hypothesized that among women receiving a false positive screening test result, those women who had experienced greater personal perceived risk for OC as well as distress would be more interested in receiving health-related information than women receiving a normal result. Analyses revealed that women receiving a false positive screening result were less interested in receiving health-related information than women receiving a normal screening result. For women receiving a false positive result, expressed interest in receipt of health-related information was only modestly related to distress and related even less to perceptions of OC risk. Our data do not support viewing a false positive OC screening result as a TM. Potential explanations for the current findings as well as recommendations for future research investigating the TM are discussed.     

Children's Anticipated Responses to Hypothetical Peers With Undesirable Characteristics: Role of Peers' Desire to Change,Effort to Change,and Outcome

The authors explored the extent to which 5th- and 6th-grade students’ anticipated responses to hypothetical peers with undesirable characteristics (e.g., being overweight) are influenced by information that each peer (a) desired (or did not desire) to change the characteristic, (b) exerted effort (or did not exert effort) to change the characteristic, and (c) was successful (or unsuccessful) in changing the characteristic. In general, the children anticipated responding more favorably to peers who were successful in overcoming an undesirable characteristic than those who were unsuccessful. However, across both outcome conditions, peers who wanted to change and exerted effort to change were rated more favorably than were peers who reported no effort to change an undesirable characteristic, regardless of whether or not they had expressed a desire to change that characteristic. For peers whose failure to change an undesirable characteristic was associated with no effort to change, those who expressed a desire to change were rated more favorably than those who expressed no desire to change.     

Triadic consistency and false heart-rate feedback

Subjects viewed slides of the Rorschach cards while listening to heart sounds that were supposedly but not actually their own. For some of the subjects the heart rate increased when they were exposed to the five achromatic cards and for some subjects the heart rate increased when they were exposed to the five chromatic cards. In addition, some subjects were told that increased heart rate was a sign of mental health (positive condition), and some that the increased heart rate was a sign of mental abnormality (negative condition) Since the heart-rate increase (behavior) and Rorschach cards associated with the increase (attitude object) are connected by a positive causal relation, triadic theory predicts that the sign of the heart-rate increase should generalize to the associated cards (i e, be positive in the positive condition and negative in the negative condition) An analysis of variance revealed such an overall significant effect Closer examination of the data, however, revealed that the triadic effects were not unambiguously occurring when the increased heart rate was associated with achromatic cards It was suggested that in this condition the unique characteristics of the cards facilitated the generation of complicating anxiety. Supportive data for this interpretation were offered     

Changes in heart rate during feedback control of respiration

Subjects received one of eight treatments: practice at increasing heart rate with heart-rate feedback, practice at decreasing heart rate with heart-rate feedback, practice at increasing heart rate without heart-rate feedback, practice at decreasing heart rate without heart-rate feedback, practice at increasing respiration rate with respiratory feedback, practice at decreasing respiration rate with respiratory feedback, practice at increasing respiration rate with respiratory instructions only, practice at decreasing respiration rate with respiratory instructions only. Heart rate, Respiration rate, and Respiration depth were measured. Analysis indicated that subjects who controlled respiration with respiratory feedback reliably increased and decreased heart rate; subjects who controlled respiration with respiratory instructions only reliably increased but not decreased heart rate; subjects in the respiratory-feedback conditions showed higher heart-rate increase and decrease than heart-rate increase and decrease of subjects in the other six conditions.
