Abstract

‘Theory of Mind’ (ToM) refers to the ability to compute, attribute and understand the mental states of both ourselves (‘Self’) and other people (‘Other’). This research explored differentiation between ‘Self’ and ‘Other’ in belief-attribution abilities, part of the ToM mechanism. Adult participants completed a computerized false-belief task in which they attributed beliefs to themselves and other people, in a matched design, assessing behavioural and neural correlates of belief-attribution to the ‘self’ and ‘other’. Participants responded faster to self-oriented than other-oriented questions, and this distinction was supported by electroencephalography (EEG) measures, largest across central parietal lobes from 550ms post-stimulus onset. Importantly, when a ‘perspective-shift’ was required within a trial, shifting from Self-to-Other was significantly slower than shifting from Other-to-Self. In contrast, in ‘no perspective-shift’ trials, no difference was observed between Self-to-Self and Other-to-Other trials. EEG measures revealed an early-onset interaction between perspective-shifting and probe type (300 ms post-stimulus presentation), maximal across-fronto central areas. Results demonstrate a differentiation between ‘Self’ and ‘Other’ within the ToM mechanism, indicating that the ‘Self’ is consistently processed, whilst the ‘Other’ is only processed when explicitly necessary. Critically, results highlight the importance of perspective-shifting abilities, at both a behavioural and neural level.
