In conclusion, our results provide strong evidence that postdecisional preference changes and performance monitoring demonstrate similar neural signatures. Subjects were instructed to relax and not move during the recordings. During Preference task I, participants rated a set of 446 food items using an 8-point Likert scale (1 = “I don't like it at all” to 8 = “I like it a lot”). You may also experience cognitive dissonance, which means that you believe two competing thoughts simultaneously. Normative decision theory suggests that our actions reflect our preferences, whereas the influential theory of “cognitive dissonance” (Festinger, 1957) postulates that our actions shape our preferences.

In this case, because we had calculations of multiple correlations, we applied permutation tests based on cluster statistics (Maris and Oostenveld, 2007). Thus, a real preference for a chosen item during the Choice task is likely to be higher than a real preference for a rejected good. Thank you for sharing this Journal of Neuroscience article. Thus, our results suggest that cognitive dissonance is reflected in both resting-state and choice-related activity of the prefrontal cortex as part of the general performance-monitoring circuitry. As expected, we found no significant difference in the ERP peak amplitude (FCz) between Self-easy trials and Computer trials (t(41) = −0.452, p = 0.654) and a significant difference between Self-difficult trials and Self-easy trials (t(41) = −2.190, p = 0.034). Crucially, we found significant interaction between trial type × choice (F(1,41) = 7.43, p = 0.009), indicating a larger SoA for Self-difficult trials than for Post-ex choice trials. In a control, Computer trials, participants were instructed to press the button corresponding to the food item randomly chosen by the computer (highlighted by a red square). Belief number 1. 2). Robotics articles will cover robotics research press releases. At the end of the experiment, we randomly selected one of the items that participants had selected during Self-difficult trials or Post-ex choice trials as an additional reward for the participants. Figure 3B shows the grand-averaged ERPs and the difference wave at the frontocentral midline electrode FCz, as well as a topographical map of the voltage distribution for the difference wave (Self-difficult − Self-easy trials). This cognitive dissonance, of course, can also work against you. To keep a mental balance, we start thinking that the car we didn’t choose wasn’t that good at all’. We also found a link between individual neural dynamics (long-range temporal correlations— LRTC) of the fronto-central cortices during rest and follow-up neural and behavioral effects of cognitive dissonance. Cognitive dissonance is a mental conflict that occurs when your beliefs don’t line up with your actions. In the present study, we focused on the analysis of alpha oscillations in the resting state for two reasons. Importantly, in this condition, changes between the two preference tasks cannot be induced by choices (cognitive dissonance). Thus, we explored whether difficult choice-induced preference changes can be driven by a neural mechanism similar to the general mechanism of performance monitoring and behavioral adjustment. EEG signals were referenced to arithmetically link mastoids. Starting in the late 1950s, people started to look at cognitive dissonance, particularly Leon Festinger and his students at Stanford, who wrote the book A Theory of Cognitive Dissonance.According to Festinger, the important factor in cognitive dissonance theory is the principle of cognitive consistency. In our experiment, we found similar frontocentral activity during the free-choice paradigm and Flanker task. His theory of cognitive dissonance is especially relevant to social psychology, especially in the areas of motivation and group dynamics. Feel free to share this Neuroscience News. A previous neuroimaging study (Izuma et al., 2010) showed the neural signature of choice-induced preference change during the rerating of options, the paradigm which was also used in our study. DOI ... Cognitive dissonance is a phenomenon which will be created based on the discomfort … Black lines indicate p < 0.001. Previous studies have indicated the maximum of ERN at FCz (Yeung et al., 2004). Thus, the SoA-related reconfiguration of neuronal value representations might require efficient rerouting of synaptic inputs and their consecutive stabilization: processes best implemented by the delicate balance of excitation and inhibition within specialized neural microcircuitry (Rolls et al., 2008). Summary: A new study uncovers the mechanism behind cognitive dissonance. We measured EEG of human subjects during rest and free-choice paradigm. Cognitive dissonance theory suggests that our preferences are modulated by the mere act of choosing. Because strong cognitive dissonance should occur during difficult decisions (Self-difficult trials and Post-ex choice), we predicted that magnitude of the SoA should be enhanced as a function of choice difficulty. Together, our electrophysiological results suggest that pMFC activity might play a critical role in modulating postdecisional preference changes occurring when difficult decisions between similarly attractive options are faced. The examinees were asked to evaluate approximately 400 food products. Furthermore, amplitudes of ERN-like potentials predicted individual differences in postdecisional preference changes: A larger ERN-like potential was associated with larger preference changes. We provide several examples of cognitive dissonance in this article.
