Relationships between researchers and participants in the life-span longitudinal studies for forty years ; Qualitative analyses of the experiences of both sides.

两项纵向研究从儿童五岁时开始在人类关系实验室（即所谓的中中营）进行，并在营地后持续了大约四十年。这两项研究都是基于对参加夏令营的儿童、母亲和研究人员的人际关系经验的定性分析。结果表明：(1)儿童在营地内内化了接受经验，并以此指导他们长大后的工作和育儿；(2)母亲和研究者意识到，他们对自己生活参考框架的重新审视与儿童的心理发展是共存的。

Two longitudinal studies were conducted which started when children were five years old at Human relationship laboratory(so called the Nakazato Camp) and lasted some forty years after the camp. Both studies were based on qualitative analyses of the interpersonal experience of children, mothers, and researchers who participated the camp.The results revealed that(1) Children have internalized acceptive experiences in the camp as a guide of their job and child rearing when they have grown up, and(2) Mothers and researchers became aware that their re-examination of their own frame of references to their lives was co-existent with children's psychological development.
