Abstract

The purposes of this study were to explore the relations of preschoolers' narrative representation profile types to diurnal cortisol regulation pattern at home. Fourteen story stems from the MacArthur Story Stem Battery (MSSB, Bretherton, et al., 1990) were administered to 40 preschoolers(22 boys, 18 girls, aged 5) recruited from 8 kindergartens in the Seoul and Gyeonggi areas. And also, their saliva cortisol was collected. The children's responses were aggregated into 5 dimensions, based on content themes and performance scores, which included emotions expressed and narrative coherence using the MacArthur Narrative Coding System(Robinson, et al., 2004). Data were analyzed by means of cluster analysis. Five response profiles emerged over the course of this research: Prosocial, Anxiety, Dyregulated aggression, Restricted, and Avoidance profiles. Cortisol at home showed decrease diurnal cortisol regulation patterns, however it showed a difference according to narrative response profiles. Restricted, Prosocial, and Avoidance profiles showed decrease diurnal cortisol regulation patterns. Anxiety profiles showed flat pattern, and Dyregulated aggression profile showed rising diurnal cortisol regulation pattern. These results show the preschoolers' internal representation may affect the diurnal cortisol reaction in daytime.

본 연구는 유아의 내적표상 유형에 따라 가정에서의 코티솔 분비 패턴이 어떠한지를 탐색해보고자 하였다. 이를 위해 40명의 유아를 대상으로 이야기 완성과제(MacArthur Story Stem Battery, Breth erton et al. 1990)를 실시하였고, 가정에서 유아의 타액을 채취하여 수집하였다. 수집된 자료는 기술통계, 군집분석을 통해 분석하였다. 분석결과 유아의 내적표상 유형은 불안유형, 제한유형, 비조절된 공격유형, 회피유형, 친사회유형의 5개 유형으로 나타났으며, 유아의 가정에서의 코티솔 분비 패턴은 오전에 코티솔 분비가 많고 오후로 갈수록 떨어지는 패턴으로 나타났다. 또한 내적표상 유형에 따라 분비패턴이 다르게 나타났다. 이러한 결과를 통해 볼 때 유아의 내적 표상이 일상적 스트레스 상황과 부모와의 상호작용시에 유아의 반응과 스트레스 호르몬의 활성화 정도에 영향을 미칠 가능성이 있음을 조심스레 예측할 수 있다.
