본 연구에서는 언어처리 과정에서 나타나는 성별의 영향을 발달초기 어휘습득의 과정에서 살펴보았다. 이를 위해 300여명의 18개월 영아와 그 어머니가 연구에 참여하였으며 18, 24, 30개월에 어휘체크리스트를 사용하여 각 영아가 가진 어휘의 수를 종단적으로 측정하였다. 그 결과, 첫째, 모든 월령에서 여아가 남아에 비해 더 많은 어휘를 가지고 있었다. 둘째, 여아의 우세는 모든 종류의 어휘에서 나타났으며 어휘의 종류와 월령의 상호작용이 있어서 서술어, 문법어, 시간어에서는 특히 18개월에 비해 24개월에 남녀의 차이가 늘어나고 30개월까지 그 차이가 유지되었다. 셋째, 회귀분석의 결과로 볼 때, 남녀 모두 명사가 다음 시기의 모든 어휘종류들에 유의한 영향력을 가지고 있으나 남아의 경우는 명사와 함께 일상생활어들의 영향이 24개월까지 지속되었다.
This study examined the longitudinal effect of infants' gender on early vocabulary acquisition. More than 290 mothers of toddlers completed a vocabulary checklist(Pae, 2002) at 18, 24 , and 30 months. The results showed that always girls had more vocabularies from 18 to 30 months. Secondly, the gender differences became bigger especially from 24 months in predicates, closed class items, and words for times. Finally, for both boys and girls, nouns were the most influencing word category for all the word categories in the next stage. However, vocabularies for routines had a lasting influence until 24 months only for boys. The results suggest that infants' gender might be a very important variable to consider in language research.
