早期自发的口面运动很少被实验研究，尽管从这些行为中获得的运动经验可能会影响言语运动技能的发展。这项调查定量描述了无声的，自发的唇和下颌运动，从1至12个月的年龄，使用基于光学的三维运动捕捉技术的发展变化。29个典型发育的婴儿在五个年龄（1，5，7，9和12个月）进行了横断面研究。婴儿表现出自发的面部运动在所有年龄段的研究。在唇和颌运动学中检测到一些与年龄相关的变化：自发运动的发生增加，运动速度增加，运动时期的持续时间减少，不同面部区域之间的运动耦合增加。此外，陈规定型观念运动的证据并不充分。目前的研究结果表明，在生命的第一年，早期自发的面部运动经历了显着的发展变化的方向技能发展的讲话。(C)2005 Wiley Periodicals，Inc.
Early spontaneous orofacial movements have rarely been studied experimentally, though the motor experiences gained from these behaviors may influence the development of motor skills emerging for speech. This investigation quantitatively describes developmental changes in silent, spontaneous lip and jaw movements from 1 to 12 months of age using optically based 3D motion capture technology. Twenty-nine typically developing infants at five ages (1, 5, 7, 9, and 12 months) were studied cross-sectionally. Infants exhibited spontaneous facial movements at all ages studied. Several age-related changes were detected in lip and jaw kinematics: the occurrence of spontaneous movements increased, movement speed increased, the duration of movement epochs decreased and movement coupling among different facial regions increased. Additionally, evidence for stereotypic movements was not strong. The present findings suggest that, during the first year of life, early spontaneous facial movements undergo significant developmental change in the direction of skill development for speech.
