ABSTRACT

This longitudinal study aimed to investigate infants’ spontaneous object interactions during naturalistic longitudinal observations in a day care centre in Japan. Infants’ and caregivers’ interactions during free play time were videotaped. The main focus related to how infants’ object interactions changed during locomotor development. Observations showed that all nine infants gradually acquired their locomotor skills, they spent about 50% of their time in contact with objects and as infants developed, they more frequently travelled to objects and carried them and their locomotion became less destination-directed. Constantly-oriented travelling episodes became less frequent, and object-carrying behaviours without explicit destinations became more frequent. The results suggested that these changes were due to infants’ posture, not their locomotor status.

摘要

这项纵向研究旨在调查日本一家日托中心在自然主义纵向观察过程中婴儿的自发物体相互作用。记录了婴儿和看护者在免费游戏期间的互动。主要关注点与运动发展过程中婴儿的物体相互作用如何变化有关。观察结果表明，所有9名婴儿逐渐掌握了运动技能，他们花费了大约50％的时间与物体接触，并且随着婴儿的成长，他们更频繁地旅行到物体并携带它们，并且他们的运动变得不那么针对目的地。固定方向的旅行事件变得不那么频繁，而没有明确目的地的携带物体的行为变得更加频繁。结果表明，这些变化是由于婴儿的姿势，
