Seeing Through Other Eyes: How Language Experience and Cognitive Abilities Shape Theory of Mind

Understanding others’ perspectives, or Theory of Mind (ToM), is a critical cognitive skill essential for social competence and effective interpersonal interactions. Although ToM is present in varying degrees across individuals, recent research indicates that linguistic factors, particularly bilingualism, can significantly influence its expression. Building on these findings, the current study examined performance on the perspective-taking trials of the Director Task among bilinguals and monolinguals. The results showed a nonsignificant trend in accurate responses as a function of bilingualism; however, a significant effect was found when examining only perspective-taking trials, with bilinguals outperforming monolinguals, suggesting that larger sample sizes are needed to identify this effect. Interestingly, a significant interaction between fluid intelligence and bilingualism was found, suggesting that bilinguals with higher fluid intelligence performed better on perspective-taking trials compared to bilinguals with lower fluid intelligence. The results emphasize the importance of domain-general abilities for the effect of bilingualism on perspective-taking and suggest that bilingualism’s effect on ToM may be more salient in individuals with higher cognitive abilities.
