The Difference of Lemma Activation Between Native Speakers of English and L2 Speakers of English With L1 Chinese: Evidence From the Semantic and Phonological Priming Effects on L2 Speech Planning

Abstract This study examined the influence of semantic and phonological priming on L2 speech planning, as well as the difference between native and non-native speakers of English in terms of lemma activation. Two potential explanations for the contrast between the performance of L2 speakers and native controls were considered. The first of which was that L2 speakers’ phonological forms are activated before selection of syntactic frame occurred, whereas the reverse is true for native speakers. The second explanation posits that the organisation of the speech production procedure is fundamentally similar in native and L2 speakers, and the disparity in performance arises from difference in the levels of activation of stored items. The results of the present experiment suggest that lemma selection is indeed what drives syntactic frame selection. However, lemmas in L2 speakers can be primed through a chain of connections demonstrated as: L2 phonological form → L1 phonological form → L1 lemma.
