Cross-linguistic influence in the processing of aspect in L2 English: Slavic, but not Norwegian L1 speakers associate past simple with completion

This study investigated the role of L1 influence on how L2 speakers interpret aspectual semantics of English past simple accomplishments. English past simple is aspectually underspecified and is thus vulnerable to the transfer of L1 aspectual representations. Slavic languages (Russian, Polish) grammaticalize dual perfective-imperfective aspect. Norwegian does not grammaticalize aspect. L1 Polish (n = 57), Russian (n = 20), and Norwegian (n = 50) speakers participated in two web-based Visual World Paradigm eyetracking experiments. Offline judgments and online gaze preferences from both experiments showed that L1 Slavic speakers associated English past simple with completed event pictures. This categorical association strengthened in offline judgments with higher L2 proficiency. L1 Norwegian speakers associated English past simple with ongoing events both online and offline. This association weakened in offline judgments with higher L2 proficiency. These findings provide evidence of L1 transfer during L2 aspectual interpretation and elucidate the interaction between crosslinguistic influence and L2 proficiency. Implications for theoretical models of cross-linguistic influence are discussed.
