48 healthy neonates born to multiparae were randomly assigned to view a moving stimulus either in the horizontal or the upright position, with or without added vestibular stimulation and with or without pacifier sucking. The infant was shown a moving black line inside a strictly controlled visual environment provided by an apparatus which permitted horizontal and upright positioning and displacement of the infant. Visual tracking was recorded by a concealed TV camera positioned at a constant distance and angle from the infants' eyes in both positions. Quality of tracking during each of 4 trials was scored on a 7-point scale. Results indicate that vestibularproprioceptive stimulation provided to the infant either horizontally or semivertically significantly enhanced his visual tracking, whereas the upright position did not. Pacifier sucking also improved his performace.
48名经产妇所生的健康新生儿被随机分配，分别在水平或直立位置观看移动刺激物，同时伴有或不伴有额外的前庭刺激，以及伴有或不伴有安抚奶嘴吸吮。在一个严格控制的视觉环境中，通过一个允许婴儿水平和直立定位及移动的装置，向婴儿展示一条移动的黑线。在两个位置，均用一台隐藏的电视摄像机从与婴儿眼睛保持恒定距离和角度的位置记录视觉追踪情况。在4次试验中的每次试验期间，追踪质量按7分制评分。结果表明，无论是水平还是半垂直给予婴儿前庭本体感觉刺激，均能显著增强其视觉追踪能力，而直立位置则不然。吸吮安抚奶嘴也能改善其表现。
