Social Rejection but Not Ostracism Increases Cognitive Effort Avoidance

Purpose: Social exclusion has been found to have a significant impact on cognitive control processing. However, the existing research on this topic has yielded inconsistent findings, possibly due to variations in the type of exclusion and individuals' cognitive effort. Two studies were conducted to explore the influence of social rejection and ostracism on cognitive effort avoidance. Participants and Methods: Study 1 involved forty-six adults who were randomly divided into a rejection group and a control group using a get-acquainted paradigm. The demand selection task (DST) was used to measure cognitive effort avoidance. In Study 2, fortyeight adults were recruited, Cyberball and DST paradigms were used to evoke ostracism and test cognitive effort avoidance, respectively. Results: The results of study 1 showed that individuals who were socially rejected by their partners exhibited impaired response accuracy of cognitive control and increased cognitive effort avoidance. This indicates that social rejection has a negative impact on cognitive control processing and that individuals may be more likely to avoid cognitive effort when experiencing social rejection. The results of study 2 showed that ostracism had an impact on both response speed and accuracy, but it did not significantly affect cognitive effort avoidance. This indicates that social rejection affects cognitive control processing differently than ostracism, and individuals are more likely to avoid cognitive effort when experiencing social rejection. Conclusion: These findings suggest that social rejection and ostracism have different effects on cognitive effort, which may contribute to the inconsistent cognitive performance during social exclusion. Future research may explore the underlying mechanisms that lead to these differences and examine how individuals can mitigate the negative effects of social exclusion on cognitive control processing.
