Crawling is considered an important motor skill for infants. Although infants show variations in their crawling, the association between crawling variations and subsequent development is unexplored. This study investigates the difference in amount of crawling variation between infants with and without subsequent developmental delays. This…

This study reports on crawling variability and differences in variability between infants with typical development (TD) and those with developmental delays. This longitudinal study included 0-year-old infants with no apparent dysfunction. The crawling movement in the video was coded objectively with reference to previous research. The infants were…

The development of children under six years of age (N = 22,819) who are enrolled in childcare…

Two years ago, the rapid retirement of the "baby boomer artisans" in vast numbers threatened to erode the competitiveness of Japanese manufacturers (i.e., the 2007 problem). This study proposes a practical process for extracting skills and designing a training system, to accelerate the learning of skills in production fields by younger…
