Feature reassembly in the acquisition of plural marking by Korean and Indonesian bilinguals: A bidirectional study

Abstract

This bidirectional study investigated the L2 acquisition of plural marking in L2 Indonesian by native Korean speakers and in L2 Korean by native Indonesian speakers. Indonesian and Korean are classifier languages with partially overlapping restrictions on how pluralization interacts with quantification, allowing us to test the acquisition of new L2 features vs. the preemption of L1 features that are not in the L2. We also examined how the contextual complexity of new L2 features impacts development. Seventy learners at three L2 Korean proficiency levels and 40 native controls participated in Experiment 1; 61 learners at three L2 Indonesian proficiency levels and 39 native controls participated in Experiment 2. All participants completed three tasks – a Sentence Completion Task, a Grammaticality Judgment Task and a Multiple-Choice Task. Whereas learners were largely able to overcome the difficulty of preemption, they were less successful in acquiring new L2 feature contrasts in more complex conditioning environments.
