与婴儿伸手相关的肢体间协调模式在发育过程中经常波动。这项研究调查了这些波动是否与协调倾向有关。研究人员对 4 名婴儿的肢体间伸手运动和非伸手运动进行了研究，并对其进行了跟踪直至他们的第一年。每周，在多次 14 秒试验中记录双臂到达和未到达终点的运动学。研究发现，伸手时的肢体间协调模式与未伸手时的协调倾向相匹配。单手操作和双手操作期间的触及范围有所不同。在双手操作期间，非触及肢体间活动往往是同步的。在单手时期，非触及性活动并未显示出肢体间协调的主要形式。有人认为，改变协调倾向可能会影响生命早期特定目标导向行为的组织。
Patterns of interlimb coordination associated with infant reaching fluctuate frequently over developmental time. This study investigated whether these fluctuations are related to coordination tendencies. Interlimb patterns were studied in reaching and nonreaching movements in 4 infants, which were followed through their Ist year. Each week, reaching and nonreaching endpoint kinematics were recorded in both arms during multiple 14-s trials. It was found that patterns of interlimb coordination in reaching matched coordination tendencies in nonreaching. Reaching fluctuated between uni- and bimanual periods. During the bimanual periods, nonreaching interlimb activity tended to be synchronous. During the unimanual periods, nonreaching activity revealed no predominant form of interlimb coordination. It is argued that changing coordination tendencies may influence the organization of specific goal-oriented behaviors from early in life.
