Связанные с событиями потенциалы мозга при восприятии референциально неоднозначных местоимений в русском языке
The study is based on the analysis of event-related potentials (ERPs) accompanying processing referentially ambiguous pronouns under condition when disambiguation is necessary for effective task performance. Participants were asked to match the pronoun in the second sentence with its antecedent (the noun phrase it is related to) in the first sentence in two conditions: experimental (two possible antecedents) and control (only one possible antecedent). Processing referentially ambiguous pronouns as compared to the control condition elicited an Nref effect – a diffuse ERP deflection 300–400 ms poststimulus that was earlier observed in Dutch and Chinese. Moreover, in contrast to previous results, no P600 effect – late positivity associated with acceptability judgment under condition of referential ambiguity – was found. Our data in comparison with results of previous studies indicate that strategies in processing referentially ambiguous pronouns (acceptability judgment) are determined not only by experimental task but also by absence/presence of anomalous trials in the experimental materials.
