Abstract: Money was found to attenuate pain caused by social exclusion, suggesting material resources affected social exclusion, which might be modulated by personality traits. This study aimed to examine how optimism modulated the money effect on social exclusion. Forty optimistic and forty pessimistic participants were required to image obtaining material worth 50 or 500 RMB. Then their social exclusion was elicited by playing cyberball games and their angry extents were recorded. The results showed that: optimistic participants felt similar anger to social exclusion regardless of monetary support, whereas pessimistic participants felt angrier when less monetary support in contrast to greater monetary support for social exclusion. Therefore, this result suggested that both material resources and mental resources modulated response to social exclusion.
