The study examined emotional experience and perceived social support during naturally occurring social interactions in Greece and Britain. Multilevel analyses found that people in Greece (a more interdependent culture) perceived less support and experienced less positive and more negative affect in social interactions than those in the UK (a more independent culture). Positive relationships between positive affect and perceptions of support were stronger in Greece than in the UK. Global perceptions of social support did not differ between the two samples, and global perceptions were weakly related to perceived support in interaction. The results support the “less is more” hypothesis (Oishi, S., Diener, E., Choi, D. W., Kim-Prieto, C., & Choi, I. (2007). The dynamics of daily events and well-being across cultures: When less is more.
