Abstract
Bilingual people have been shown to have an enhanced theory of mind, particularly with children. I tested whether this bilingual advantage would remain for adults when measuring their responses with mouse-tracking methodology. I hypothesized that mouse-tracking measures would indicate that bilingual individuals show less egocentric response conflict as compared to monolingual individuals. I tested this hypothesis with a set of false belief tasks and sets of theory of mind tasks which focused on cognitive and affective theory of mind respectively. Participants did not show a significant difference in their response conflict between monolinguals and bilinguals for any of the tasks, although initiation time was significantly different on the cognitive task. I discuss implications of this result and explore certain characteristics of the results as well as future directions of research.
