通过对13对中等收入的1 ~ 6个月大的母子二人组每周自由玩耍的实验室观察，研究了婴儿体位和凝视方向之间发育轨迹的同步性。母亲们坐在直背椅子上，把婴儿抱在腿上，可以自由调整婴儿的姿势。体位被编码为直立（支撑着坐或站在别人的腿上）或其他（躺着，抱着，或靠近母亲）。凝视被编码为要么盯着母亲的脸，要么离开。还评估了视觉引导到达的开始年龄。结果表明，当婴儿处于直立姿势时，他们凝视别处的时间更长。在5个月的观察期间，二对开始出现非直立姿势，并凝视母亲。与之前的预测相反，前6个月婴儿从只盯着母亲的脸到把目光从母亲身上移开的发育转变与手的发育并不同步，而是与婴儿的姿势向更直立的姿势的变化同步。讨论了体位在促进积极情绪沟通中的可能作用。
Weekly laboratory observations of free play for 13 middle-income mother-infant dyads, from 1 to 6 months of age, were used to study the synchronization of developmental trajectories between infant postural position and gaze direction. Mothers sat in a straight-backed chair while holding infants on their laps and were free to adjust the infant's posture. Postural position was coded as upright (supported sitting or standing on them other's lap) or other (lying, cradling, or being held close to mother). Gaze was coded as either at mother's face or away. The age of onset of visually guided reaching was also assessed. Results show that there were longer durations of gazing away when the infant was in an upright position. Over the 5 month period of observation, the dyads began with a pattern of non-upright positions accompanied by gaze at mother. Contrary to previous predictions, the developmental shift in the first 6 months from exclusive gazing at mother's face to gazing away from mother was not synchronized with the development of reaching, but rather with changes in the infant's posture to more upright positions. The possible role of postural position in fostering positive emotional communication is discussed.
