考察了婴儿对静止和移动目标的触手技能的组织情况。当58名足月、5.5个月、8.5个月和11.5个月的健康婴儿伸手拿起并抓住覆盖着布的桩子时，他们的伸展范围被录像下来，用于以后的慢动作分析。分析涉及婴儿对手部对齐的预期调整，使用旋转和摆动目标的信息来更新正在进行的范围，以及捕获深入移动的目标的能力。所有年龄段的婴儿都进行了手部对齐的预见性调整，尽管这些调整的有效性随着年龄的增长而提高。无论年龄如何，婴儿也使用来自旋转和振荡目标的动态信息来更新正在进行的触角，但婴儿使用这些信息的方式与年龄有关。发展恒定性是婴儿接近目标的特点。通过观察婴儿对静止、旋转和接近目标的伸展，这项研究扩大了考察适应伸展技能的条件范围，并提供了对预期和更新在早期手动技能发展中的作用的洞察。
The organization of infants' reaching skill for stationary and moving targets was examined. While 58 term, healthy infants at 5.5, 8.5, and 11.5 months of age reached for and grasped a cloth‐covered dowel, their reaches were videotaped for later slow‐motion analysis. Analyses addressed infants' anticipatory adjustment of hand alignment, use of information from spinning and oscillating targets to update ongoing reaches, and ability to capture targets moving in depth. Infants at all ages made anticipatory adjustments of hand alignment, although the effectiveness of these adjustments improved with age. Regardless of age, infants also used dynamic information from spinning and oscillating targets to update ongoing reaches, but the way infants used this information was related to age. Developmental constancy characterized infants' reaches for approaching targets. By observing infants' reaches for stationary, spinning, and approaching targets, the study expands the range of conditions under which adaptive reaching skill has been examined and provides insight into the roles of anticipation and updating in the development of early manual skill.
