(1) examine infant movement during an early posture (sitting) utilizing a novel video assessment technique; and (2) document the differences between infants with typical development (TD), premature infants with motor delay, and infants with cerebral palsy (CP) during focused and nonfocused attention (NFA).
Infants were tested when they began to sit independently. We utilized Eulerian Video Magnification (EVM) to accentuate small trunk and pelvic movements for visual coding from video taken during a natural play task with and without focused attention (FA).
Trunk/pelvic movement varied as a function of both motor skill and attention. Infants with TD and CP made fewer trunk movements during periods of FA than NFA. Preterm infants exhibited more trunk/pelvic movement than the other groups and their movement did not differ based on attention type.
The EVM technique allowed for replicable coding of real-time "hidden" motor adjustments from video. The capacity to minimize extraneous movements in infants, or "sitting still" may allow greater attention to the task at hand, similar to older children and adults. Premature infants' excessive trunk/pelvic movement that did not adapt to task requirements could, in the long term, impact tasks requiring attentional resources.
（1）运用一种新颖的视频评估技术，检查婴儿在早期姿势（坐姿）时的运动情况；（2）记录典型发育（TD）婴儿、运动发育迟缓的早产儿以及脑瘫（CP）婴儿在集中注意力和非集中注意力（NFA）期间的差异。
在婴儿开始独立坐立后对其进行测试。我们利用欧拉视频放大（EVM）技术突出躯干和骨盆的微小运动，以便对在有和没有集中注意力（FA）的自然游戏任务中拍摄的视频进行视觉编码。
躯干/骨盆运动因运动技能和注意力而异。TD婴儿和CP婴儿在FA期间的躯干运动比NFA期间少。早产儿的躯干/骨盆运动比其他组更多，并且其运动在注意力类型方面没有差异。
EVM技术能够对视频中的实时“隐藏”运动调整进行可重复编码。婴儿减少无关运动或“坐定不动”的能力可能有助于更专注于手头任务，这与大龄儿童和成年人类似。早产儿过度的躯干/骨盆运动若不适应任务要求，从长远来看，可能会影响需要注意力资源的任务。
