The Effects of Adult Aging and Culture on Theory of Mind

Yong MH, Lawrie L, Schaefer A, Phillips LH

J Gerontol B Psychol Sci Soc Sci, 2022 Feb 03;77(2):332-340.
PMID: 34036302 DOI: 10.1093/geronb/gbab093

OBJECTIVES: Older adults tend to have poorer Theory of Mind (ToM) than their younger counterparts, and this has been shown in both Western and Asian cultures. We examined the role of working memory (WM) in age differences in ToM, and whether this was moderated by education and culture (the United Kingdom vs. Malaysia).
METHODS: We used 2 ToM tests with differing demands on updating multiple mental states (false belief) and applying social rules to mental state processing (faux pas). We also looked at the role of education, socioeconomic status, and WM. A total of 298 participants from the United Kingdom and Malaysia completed faux pas, false belief, and WM tasks.
RESULTS: Age effects on some aspects of ToM were greater in the Malaysian compared to the UK sample. Malaysian older adults were poorer at faux pas detection, aspects of false belief, and WM compared to young adults. In subsequent moderated mediation analyses, we found that, specifically in the Malaysian sample, the mediating effects of WM on the age and ToM relationship occurred at the lowest levels of education.
DISCUSSION: This pattern of results may reflect changes in the familiarity and cognitive load of explicit mental state attribution, along with cultural differences in the pace and nature of cognitive aging. Cultural differences in education and WM should be considered when researching age differences in ToM.

Planning ability is important in everyday functioning, and a key measure to assess the preparation and execution of plans is the Tower of London (ToL) task. Previous studies indicate that older adults are often less accurate than the young on the ToL and that there may be cultural differences in performance on the task. However, potential interactions between age and culture have not previously been explored. In the current study we examined the effects of age on ToL performance in an Asian culture (Malaysia) and a Western culture (British) (n = 191). We also explored whether working memory, age, education, and socioeconomic status explained variance in ToL performance across these two cultures. Results indicated that age effects on ToL performance were greater in the Malaysian sample. Subsequent moderated mediation analysis revealed differences between the two cultures (British vs Malaysians), in that the age-related variance in ToL accuracy was accounted for by WM capacity at low and medium education levels only in the Malaysian sample. Demographic variables could not explain additional variance in ToL speed or accuracy. These results may reflect cultural differences in the familiarity and cognitive load of carrying out complex planning tasks.
