아동의 언어발달 단계에 관한 심리학적 연구 Ⅰ : 초기 언어 = A Psychological Study on Linguistic Developmental Stages of Children

다국어 초록 (Multilingual Abstract)

This study, in which the data were longitudinal transcriptions of the spontaneous speech of three Korean children, aimed at depicting developmental stages of their language. In order to write generative grammars of the three children's utterances, analysis of distributional characteristics and underlying semantic relations were made. Thereafter, the following five developmental stages of earlier child language were proposed:
Monoreme stage, which has been traditionally called one-word sentence;
Duoreme stage, in which the first-position word of the two-word utterance functions either as a vocative or a deictic interjection:
Two-word sentence-stage, in which either syntactical relation in grammartical level or case-relationship in cognitive level is explicitly implied;
Three or more words sentence stage, a stage of more complex constructions of hierarchical structures in which semantical relation as well as sentence length is more complicated.
