아동의 구문발달에 따른 용언의 발달

Abstract

Children seem to develop the ability to create syntactic forms by learning and using predicates, composed of adjectives and verbs. The purpose of this study was to investigate the relationships between children’s syntactic ability and the ability of predicate production. Thirty-five children who are mainly using two or three words in an utterance(21 males and 14 females) participated in this study. The mean age of the children is 31.9 months(range: 22-41 month). Subjects were required to play freely with six sets of toys. After gathering the samples of spontaneous speech, we evaluated the MLUw, MLUm, TNP, and NDP. MLUw and MLUm were computed by Korean Computerized Language Analysis, Version 2.0 (KCLA). TNP and NDP were manually calculated. The results were as follows. A significant increase was found in TNP and NDP along with an increase in MLUw and MLUm. The three groups defined in terms of MLUw showed differences. TNP increased successively in each of the three groups, whereas an increase in NDP in MLUm was found only in group II. Moreover, a significant difference in TNP was found only between group II and group III, and that of NDP, between group I and group III. The implication of the study is that children acquire language in two successive periods.
