This preregistered study uses a combination of physiological measures to explore both the activation and reduction components of cognitive dissonance theory. More precisely, we use skin conductance to identify dissonance arousal, a short-term affective response to counter-attitudinal stimuli, and then use heart rate variability to measure dissonance reduction, which reflects longer-term patterns of emotional regulation and information processing. Our preliminary tests find weak evidence of dissonance arousal and no evidence of dissonance reduction using this physiological approach. We consequently reconsider (albeit optimistically) the use of physiology in future work on cognitive dissonance. We also discuss the implications of our findings for selective exposure and motivated reasoning.
这项预先注册的研究采用了多种生理测量方法，以探究认知失调理论中的激活和缓解成分。更确切地说，我们使用皮肤电传导来识别失调唤醒，这是一种对反态度刺激的短期情感反应，然后使用心率变异性来测量失调缓解，它反映了情绪调节和信息处理的长期模式。我们的初步测试发现，使用这种生理方法，有微弱的证据表明存在失调唤醒，但没有证据表明存在失调缓解。因此，我们重新考虑（尽管是乐观地）在未来关于认知失调的研究中使用生理学方法。我们还讨论了我们的研究结果对选择性接触和动机性推理的影响。
