Adult native speakers (L1) of Russian and advanced nonnative second-language (L2) speakers read Russian sentences on a computer and were asked to choose one of two inflected past-tense verbs in a forced-choice task. Verbs either matched or mismatched gender of the subject-noun phrase. Data suggested that L1 and L2 speakers may depend on common learning mechanism and thus resemble one another at computational level. (Author/VWL)
