한국어 학습자의 명사구 격 표시 연구

The study has investigated the acquisition of Korean case marking of L2 learners. Case attachment, case alteration and case stacking in verb complements and adjuncts, were sub-categorized into 6 types which provided the linguistic context to examine these interlanguage phenomena. 30 native speakers of Korean(NK), 30 L1 Chinese speakers of Korean(CK), and 30 L1 Japanese speakers of Korean(JK) were asked to indicate their grammatical judgment on diverse case marking. A series of independent t-tests on the grammatical judgment of the participants were conducted to examine whether there existed differences between ‘Native speakers vs. Learners’(RQ 1), and to examine whether there existed differences upon L2 learners’ L1(RQ 2). The results can be summarized as follows: (1) In most case marking types, there were significant differences between the grammatical judgment of L2 learners and that of their NK counterparts, except in the Adjunct type. And (2) there were not significant differences between the grammatical judgment of JK and that of CK except Case select type. Additional frequency analyses were conducted to investigate which case markings made major differences in the grammatical judgement of Korean native speakers and L2 learners.
