学会走路可以扩大婴儿对物理环境的接触，并促使他们的交流行为发生变化。然而，很少有人知道走路是否也会影响婴儿在日常活动中与成年社交伙伴的接近程度。我们跟踪了89个婴儿（42名男孩，47名女孩; 92%的白色，不是西班牙裔或拉丁美洲人）纵向记录了婴儿运动和婴儿-成人接近之间的联系，在两个时间尺度上：（1）在整个发育时间内，通过比较婴儿只能爬行的一段时间的数据，到他们可以走路的以后一段时间（M步行起始= 12.15个月，范围= 8-15）;和（2）在真实的时间中，通过测试婴儿在运动中花费的时间量（无论他们的运动状态如何）是否与他们与成人的人际距离有关。发育过渡到步行对应于一个显着的，但适度的，减少婴儿-成人接近。然而，婴儿的每时每刻的运动与人际距离模式密切相关：运动时间越长的婴儿在成人附近的时间越少，并且引发了更多的接近过渡，导致整个过程中的接近时间更短，更分散。研究结果揭示了婴儿的运动成就如何在其他发展领域产生影响，以及研究人员在几个月内经常观察到的婴儿发展变化如何来自婴儿的瞬间体验。
Learning to walk expands infants' access to the physical environment and prompts changes in their communicative behaviors. However, little is known about whether walking also shapes infants' proximity to their adult social partners during everyday activities at home. Here we followed 89 infants (42 boys, 47 girls; 92% White, not Hispanic or Latino) longitudinally and documented connections between infant locomotion and infant-adult proximity on two timescales: (1) across developmental time, by comparing data from a session when infants could only crawl to a later session when they could walk (M walk onset = 12.15 months, range = 8-15); and (2) in real time, by testing whether the amount of time that infants spent in motion (regardless of their locomotor status) related to their interpersonal distance to adults. The developmental transition to walking corresponded to a significant, but modest, decrease in infant-adult proximity. Infants' moment-to-moment locomotion, however, was strongly related to patterns of interpersonal distance: infants who spent more time in motion spent less time near adults and instigated more proximity transitions, resulting in shorter and more dispersed bouts of proximity throughout sessions. Findings shed new light on how infants' motor achievements can reverberate across other domains of development, and how changes in infant development that researchers often observe over months arise from infants' moment-to-moment experiences.
