Selective exposure to information and cognitive dissonance

Despite numerous attempts, the selective exposure prediction of Festinger's (A theory of cognitive dissonance. Evanston, Ill.: Row, Peterson, 1957) theory of cognitive dissonance has not been consistently demonstrated. In previous studies, this failure can be attributed to design deficiencies, and other related problems. The present study manipulated dissonance by having subjects write a counterattitudinal essay under conditions of high or low choice. Information in the form of pamphlets and discussion groups was offered to the subjects such that they could choose information that was consonant and dissonant with the decision to write the essay. The information was offered either before or after an attitude measure on the essay topic, as the attitude measure could also be a source of dissonance reduction. The results indicate that the high choice manipulation yielded greater attitude change than the low-choice manipulation. High-choice subjects desired consonant information more and dissonant information less than did low-choice subjects. This effect was found for both measures of information desire (pamphlets and discussion groups). Low-choice subjects who received the attitude questionnaire before the information measures wanted information more than if offered the information before the attitude questionnaire, implying a sensitizing effect produced by the attitude questionnaire for the low-choice subjects. The various effects are discussed as providing support for predictions from Festinger's dissonance theory.     

Confirmation bias in sequential information search after preliminary decisions: an expansion of dissonance theoretical research on selective exposure to information

Research on selective exposure to information consistently shows that, after having made a decision, people prefer supporting over conflicting information. However, in all of these experiments participants were given an overview of all available pieces of information, selected them simultaneously, and did not process the requested information during the selection phase. In the present research the authors show that an even stronger preference for supporting information arises if information is presented and processed sequentially instead of simultaneously (Experiment 1), and they demonstrate that this stronger confirmation bias is due to sequential presentation and not to sequential processing of information (Experiment 2). The authors provide evidence that the increase in confirmation bias under sequential presentation is caused by heightened commitment due to the participants' increased focusing on their decision (Experiments 3 and 4).     

Selective exposure and decision framing: The impact of gain and loss framing on confirmatory information search after decisions

When people make decisions, they often prefer to receive information that supports rather than conflicts with their decision. To date, this effect has mainly been investigated in the context of decisions about gains, whereas decisions about losses have received less attention. Based on Prospect Theory, we expected information search to be differently affected by whether people previously have decided about gains or losses. Three studies have revealed that selectivity of information search is stronger after gain-framed rather than after loss-framed decision problems. An investigation of the underlying psychological processes revealed that gain decisions are made with increased subjective decision certainty (i.e. they are easier and less effortful to make), which in turn systematically increases confirmatory information search.     

Connecting terror management and dissonance theory: Evidence that mortality salience increases the preference for supporting information after decisions

From the perspective of terror management theory, reminders of mortality should intensify the desire to pursue cognitive consistency. The authors investigated this notion with regard to dissonance theory starting from the finding of research on "selective exposure to information" that after having made a decision, people prefer consonant over dissonant information. The authors found that following mortality salience, people indeed showed an increased preference for information that supported their decision compared to information conflicting with it. However, this only occurred with regard to a worldview-relevant decision case. For a fictitious decision scenario, mortality salience did not affect information seeking. Practical and theoretical implications are discussed.     

Selective exposure to self

Male undergraduates received either an accepting or unaccepting communication from a coed. Then each subject had the opportunity to listen to his own voice or the voice of another male, and it was found that preference for listening to one's own voice was higher among subjects who had received positive feedback from the coed. There was also evidence that this pattern of selective exposure is weakened when feedback is less impactful. The results were interpreted through a theory of objective self awareness.     

Threat and selective exposure: the moderating role of threat and decision context on confirmatory information search after decisions

Previous studies on the impact of perceived threat on confirmatory information search (selective exposure) in the context of decision making have yielded mixed results. Some studies have suggested that confirmatory information search is reduced, yet others have found contradictory effects. The present series of 5 studies consistently found that the crucial moderator for these inconsistent findings was whether the induced threat was contextually related to the subsequent decision and information search tasks. Contextual incongruence (e.g., an induction of terrorist threat followed by an economic decision case) results in reduced levels of confirmatory information search, whereas a congruent threat (e.g., an induction of terrorist threat followed by a decision case on terrorism) results in increased levels of confirmatory information search. Analyses of the underlying psychological processes revealed that decision-unrelated threat inductions increase decision makers' experienced decision uncertainty, thus reducing confirmatory information search.     

The similarities between cognitive dissonance and guilt: Confession as a relief of dissonance

It is proposed that dissonance is similar to the feeling of guilt. If they are in fact analogous, and confession relieves guilt, then one implication is that confession would relieve dissonance. This experiment tested this prediction using a standard induced compliance paradigm. Forty-five undergraduate subjects were assigned to either a no-choice condition, a choice-confession condition, or a choice-no-confession condition. The results indicate that confession does relieve dissonance. Further, as predicted, a negative correlation was found between attitudinal shift and guilt. The implications of the findings concerning the mechanisms of confession are discussed.

Reduction of cognitive dissonance as a function of magnitude of dissonance,differentiation, and self-esteem

The purpose of the present experiment was to test several hypotheses concerning the interrelationship of dissonance reduction mechanisms in a situation where response possibilities are relatively unconstrained. Engaged female students were invited to take part in a bogus ?Marriage Expectancy Test' that was supposed to allow predictions of marriage success. One week later, they received fictitious results differing negatively from their initial expectations of marriage success. The reactions measured were ?conformity with the result' and ?derogation of source' (confrontation mechanisms), and ?devaluation of importance of the issue' and ?under-recall' (avoidance mechanisms). As predicted, avoidance responses increased steeply with discrepancy, while little increase was found for confrontation mechanisms. Psychological differentiation had no significant effect on dissonance reduction, whereas high vs. low self-esteem influenced ?derogation of source' and ?devaluation of importance of the issue'.     

Choice ambiguity, dissonance, and defensiveness

Female repressors and sensitizers were presented with a choice between two pens of different colors from five which they had previously rated on a relative-attractiveness scale Following choice, they rerated the pens under one of two conditions (a) where the choice had unequivocal implications for their femininity or (b) where it had equivocal implications for femininity Attractiveness ratings of the pens before and after choice constituted the major dependent variable Repressors tended to show greater average change in ratings than sensitizers under low ambiguity but not under high ambiguity Skin conductance measurements did not show interpretable dissonance effects, but there was evidence of R-S differences in skin conductance and self-report measures of tension     

Homeostasis,discrepancy, dissonance

The argument is presented that motivation is equated to energy mobilization, and that the mechanism involved in all such instances of arousal is a discrepancy-detecting and -reducing mechanism. Motives are specific categories of discrepancy but they operate through a common arousal system. This system, further, may be coopted into (integrated into) processes involving social comparison, relative deprivation, discrepancies with respect to ego-involved persons and objects, and industrial, social, and political motives. While biological homeostasis provides the basic CNS system, other forms of discrepancy-triggered energy arousal must be recognized as important. Hedonism and theories of curiosity, as well as other similar factors, can be subsumed under discrepancy theory.A portion of this paper was prepared with the support of NIMH Fellowship 1-F03-MH-54564-01.     

Physiological and cognitive effects of expressive dissonance

Emotional well-being depends in part on affect modulation. The present study extends research on emotion regulation by assessing the physiological and cognitive effects of a novel response-focused regulation strategy, termed 'expressive dissonance.' Expressive dissonance refers to the incongruence between an emotional state (e.g., sadness) and a behavioral expression (e.g., a smile). Fifty-five participants watched a series of sad film clips in which they were asked to either naturally watch or express the opposite of what they were feeling. Results suggest that persons using the expressive dissonant strategies evidenced greater sympathetic arousal and performed worse on subsequent memory tasks than persons in the natural-watch conditions.     

Selective responses to threat: the roles of race and gender in decisions to shoot

Extensive work over the past decade has shown that race can bias perceptions and responses to threat. However, the previous work focused almost exclusively on responses to men and overlooked how gender and the interaction of race and gender influence decisions regarding use of force. In the current article, two studies examine the implications of gender (Study 1) and both race and gender (Study 2) for decisions to shoot criminal suspects on a computerized simulation. In Study 1, participants were biased away from shooting White female suspects compared to White male suspects. In Study 2, White participants showed a pronounced bias toward shooting Black men but a bias away from shooting Black women and White ingroup members, providing evidence of a behavioral threat-related response specific to outgroup men stereotypically associated with aggression. The theoretical and practical implications of these findings are discussed.
