Fourteen infants were each videotaped 7 times within the first 12 weeks of life to determine whether or not the asymmetrical tonic neck reflex had a role in placing their hands within their fields of vision. Infants' arms were more frequently out of the reflex position. Hands were within the peripheral visual field more often than in the focal visual field or not within the visual field. The proportion of observations that hands were in a particular visual field varied in accordance with the presence or absence of the reflex. A higher proportion of reflex observations occurred in the focal visual field, whereas a higher proportion of observations made when the infants were not in the reflex position occurred in the peripheral visual field. Further, the proportion of focal field observations in the reflex position was greater than the proportion of observations out of the reflex position for the first six of the seven ages. This study confirms that when infants are in the asymmetrical tonic neck reflex position, their hands are more likely to be in a position in which they can be visualized.
14名婴儿在出生后的前12周内每人被录像7次，以确定非对称性紧张性颈反射是否在将手置于视野范围内起作用。婴儿的手臂更频繁地处于反射位置之外。手出现在周边视野的频率高于中央视野或不在视野范围内。手处于特定视野的观察比例根据反射的有无而变化。反射观察在中央视野中出现的比例更高，而婴儿不在反射位置时进行的观察在周边视野中出现的比例更高。此外，在七个年龄段中的前六个年龄段，处于反射位置的中央视野观察比例大于不在反射位置的观察比例。这项研究证实，当婴儿处于非对称性紧张性颈反射位置时，他们的手更有可能处于可以被看到的位置。
