Abstract
We aimed to clarify how infants interact with their surroundings and how this changes as they grow. This study reviewed video-recorded scenes where infants contacted surrounding objects at a nursery center. We identified contacted objects, contact duration, contact-related events, and adult involvement, then examined the developmental changes in how infants interact with surroundings and contingent events. We found that the duration of object contact was shorter for crawlers and walkers than pre-crawlers and longer with adult involvement than without. Crawlers and walkers showed greater variations in patterns of object contact and interaction with adults than pre-crawlers. These results suggest that how infants interact with their surroundings is influenced by adult involvement, and that their own developmental status largely contributes to the diversity of their experiences with objects in the environment.
