Interhemispheric communication and the preference for attitude consistent information

The current study investigated the role of interhemispheric communication in selective exposure to information. Participants (N = 241) reported their attitude and attitude strength toward a controversial social topic, engaged in a selective exposure task, and completed the Poffenberger paradigm. As expected, participants demonstrated a moderate (d = 0.50) preference for attitude consistent information on the selective exposure task and attitude strength was a significant predictor of participants' information search tendencies. Furthermore, faster right-to-left interhemispheric transfer was also significantly associated with an increased preference for attitude consistent information. These findings highlight the potential role of the right hemispheric processes in the detection of cognitive inconsistency and in the implementation of dissonance reduction strategies.
