부정사 ‘안’의 발화 오류로 분석한 유아의 암묵적 모국어 학습

Abstract

This study aims to examine the role of infants’ implicit knowledge in the acquisition of their mother tongue by investigating the acquisition process of the Korean negation an. Based on the raw data of the verbal utterances of two Korean infants between the ages of 17 to 38 months, this paper selectively collected the utterance errors of the Korean negation an. This paper used the Symbolic Computational Model as a theoretical framework and set up four propositional rule- discovering stages: i) typical model search, ii) latent rule discovery, iii) rule application expansion, and iv) rule confirmation and settlement. The final results of analysis are as follow: the infants i) take their parents’ formulaic expressions as the typical models of learning, ii) set up propositional hypothesis on the rules of negation ‘an’ and apply them to relevant phrasal structures, iii) attempted to apply acquired rules to new phrases, which tend to result in under- or over- generalizations. Finally, they confirm the critical rules for the usage of the negation an and make no further errors.
