Objectives: The current study examined the effect of birth weight on the relationship between age and IQ of children, who were born preterm with very low birth weight (VLBW) or extremely low birth weight (ELBW). Methods: The study subjects were 82 children, aged between 3-5 years, who visited the neonatal intensive care unit of a university hospital located in Seoul. The children had been born prematurely with VLBW or ELBW. Their IQ was tested using the performed Korean-Wechsler Preschool and Primary Scale of Intelligence fourth edition. Results: A hierarchical regression analysis showed a significant interaction effect of birth weight and age on Full Scale IQ (FSIQ); the effect of age on FSIQ differed according to birth weight. For the group with VLBW, FSIQ was more likely to be higher with increasing age. Conversely, for the group with ELBW, FSIQ remained low regardless of the age level. In addition, birth weight and age had a significant interaction effect on the Visual Spatial Index. Birth weight had a significant main effect on Verbal Comprehension Index. Conclusion: This research suggested the possibility of predicting the cognitive developmental of premature children, by highlighting the fact that prematurely born children, with VLBW/ELBW, have different cognitive developmental trajectories.

The purpose of this study is to investigate the moderating effects of language abilities associated with between emotionality, attention deficit hyperactivity disorder (ADHD) and peer play interactions. Two hundred fifty-two participants were 3 year olds, with 136 boys and 116 girls. They were recruited from day care centers and preschools in Gyunggi province and Incheon city. Peer play interaction was assessed by the Penn Interactive Peer Play Scale (PIPPS). Emotionality was measured by Child Behavior Questionnaire (CBQ). ADHD was assessed by teacher ratings of ADHD syndrome. Language abilities were measured by Korean Wechsler Preschool and Primary Scale of Intelligence (K-WPPSI). Teachers completed questionnaires to assess peer play interactions, emotionality, ADHD. The results revealed that language abilities moderated relationships between emotionality and play in isolation. The magnitude of associations between emotionality and play in isolation was greater for high levels of language abilities. Moreover, there were moderating effects of language abilities associated between ADHD and play disruptions. Although ADHD was significantly associated with play disruptions, the association was stronger at the higher levels than the low levels of language abilities. It can be deduced that language abilities of 3 year old children affects the protection factor between emotionality and peer play isolation; whilst, it affects the risk factor on peer play disruptions and ADHD propensity.

본 연구는 뉴로피드백 훈련이 유아의 뇌 기능과 지능에 미치는 영향에 관한 연구로 첫째, 뉴로피드백 훈련이 유아의 뇌 기능에 어떤 변화를 주는지를 검증하였으며, 둘째, 한국 웩슬러유아지능검사(K-WPPSI: Korean Wechsler Preschool and Primary Scale of Intelligence)를 통해 뉴로피드백 훈련이 유아의 지능 발달에 어떤 영향을 미치는지를 분석하였다. 본 연구는 천안 소재의 J 유치원에 재원중인 만5세 유아 60명을 대상으로, 2008년 4월 21일부터 12월 12일에 걸쳐 뉴로피드백 훈련 지침에 따라 훈련을 실시하였다. 뉴로피드백 훈련 전과 후의 뇌기능지수와 지능을 분석하였으며, 통계분석은 SPSS for Window 13.0 패키지를 사용하여 t-검증을 통해 분석하였다. 분석 결과 첫째, 뇌기능 지수 전체를 종합 평가한 브레인지수는 유의미한 영향을 미치는 것으로 나타나, 뉴로피드백 훈련이 유아의 뇌 기능 발달에 매우 효과적인 방법임을 알 수 있었다. 둘째, 뉴로피드백 훈련이 동작성 지능 지수 중 도형 영역, 미로 영역, 빠진 곳 찾기 영역은 유의미한 영향을 미치는 것으로 나타났으며, 종합적인 평가 지수인 동작성 지능 지수도 유의미한 영향을 미치는 것으로 나타났다. 따라서 이러한 실험 결과는 뉴로피드백 훈련이 동작성 지능 지수 발달에 매우 효과적인 방법임을 알 수 있었고, 세째, 뉴로피드백 훈련은 언어성 지능 지수 중 공통성 영역만 유의미한 영향을 미치는 것으로 나타났다.
