Link: https://zoom.us/j/2141505396 We report the results of a Visual World eye-tracking study investigating the processing of verbal aspect by Russian-speaking (n=124) and English-speaking (n=35) adults. The participants looked at pairs of pictures representing an ongoing event and a corresponding completed event, and listened to pre-recorded sentences where we manipulated the aspect of the verb (Perfective/Imperfective for Russian, Past Progressive/Simple Past for English). The participants were asked to choose the picture that best corresponded to the sentence. The analysis of eye movements and offline responses revealed that the Russian speakers showed a strong preference for the ongoing event picture when they heard a sentence involving an Imperfective verb. Conversely, they strongly preferred the completed event picture when they heard a Perfective verb. In contrast, English speakers strongly preferred the ongoing event pictures when they heard sentences involving a verb in the Past Progressive form, but showed no preference when the sentence involved a verb in the Simple Past form. This indicates that English Simple Past is not in paradigmatic opposition to the Past Progressive, unlike the Perfective and Imperfective in Russian. Furthermore, we hypothesize that the contrast in gaze patterns between the English Progressive and the Russian Imperfective may reflect the difference between processing a lexical distinction (in Russian) vs. a rule-based compositional process (in English).
