Older adults tend to have poorer mental state understanding (Theory of Mind, ToM) than their younger counterparts, including in both Western and Asian cultures. The current study aimed to directly investigate whether there are any cultural differences in the pattern of age effects on ToM tasks. Given evidence of cultural differences in the development of ToM across childhood, we predicted that older Asian adults would find the mental state tasks particularly resource-demanding. We used two ToM tests which made differing demands on updating multiple mental states (the false belief task) and applying social rules to mental state processing (the faux pas task). We also looked at the role of education, socioeconomic status, individualism versus collectivism and working memory (WM). A total of 298 participants from UK and Malaysia completed faux pas, false belief, and WM tasks. Results showed that interacting effects of age and culture were evident in faux pas detection, some aspects of false belief reasoning, and WM tasks, with older Malaysian participants performing poorly compared to the other groups. We also found that WM fully mediated age differences in ToM in the Malaysian sample. High levels of individualism were associated with poorer faux pas detection, but education and socioeconomic status did not explain additional variance in the ToM tasks. This pattern of results may reflect generational changes in the familiarity and cognitive load of explicit mental state attribution, along with cultural differences in the pace and nature of cognitive ageing.
