Hierarchy and dynamics of self-referential processing: The non-personal Me1 and the personal Me2 elicited via single words

Recent electroencephalography (EEG) studies accumulated evidence that support a dynamic view of the self (multiple aspect theory). In this study, we test the specific hypothesis of the multiple aspect theory of the self by using EEG data from the HisMine paradigm. In the HisMine paradigm German pronouns are visually presented in a stream of additional stimuli, while changes in brain activity are determined by means of EEG. At an early cortical processing stage, the presentation of the possessive pronouns "mein" ("my"), "sein" ("his") and "dein" ("your") elicited significantly different brain activities when compared to the non-personal pronoun "ein" ("a"). At a later processing stage, cortical processing of the self-related possessive pronoun ("mein") differed from the processing of all other possessive and the non-personal pronoun. In line with previous observations (and the multiple aspect theory of the self), the early effect (here referred to as Me1) was found at specifically left occipito-parietal electrode locations (e.g. PO9), whereas the later effect (here referred to as Me2) occurred specifically at the left fronto-temporal electrode site, F7. This finding supports the idea that the human self is consisting of multiple aspects. Potential implications are discussed.
