Proficiency modulates early orthographic and phonological processing in L2 spoken word recognition

The present study investigated orthographic and phonological processing in L2 French spoken word recognition with Finnish learners of French using the masked cross-modal priming paradigm. Experiment 1 showed a repetition effect in L2 within-language priming that was most pronounced for high proficiency learners and a significant effect for French pseudohomophones. In the between-language Experiment 2, high proficiency learners showed significant facilitation from L1 Finnish to L2 French shared orthography in the absence of phonological and semantic overlap.  This effect was not observed in the lower intermediate group, which showed a significant benefit of L1 pseudohomophones instead. The orthographic effect in the high proficiency group was modulated by subjective familiarity showing facilitation for less familiar but not for highly familiar words. The results suggest that with L2 learners, the extent to which orthographic information affects L2 spoken word recognition depends on their L2 proficiency
