婴儿知觉发展的领域在很大程度上依赖于偏好性注视和习惯化范式。尽管采用标准化的方法有明显的优势，但有必要研究感知变量如何引起和指导新生儿时期开始的行动。有人认为，在生命的前5个月，重要的是要区分自主和皮质控制的模式的运动反射模式。定义了一些标准。本文介绍了三个实验，利用运动计数器记录的发展变化的频率和同步性的肢体运动在5个月以下的婴儿。结果表明：1 ~ 5个月时，肢体运动频率普遍增加，但从3个月中旬到4个月末，肢体活动趋于平稳甚至减少。研究还表明，从1个月到5个月，成对肢体的同步性评分（共激活）显着增加。最后，在所有三个实验中，一个有吸引力的玩具的介绍导致抑制活动。这三个实验的结果被解释为测量皮质控制的运动模式的逐渐增加。
The field of infant perceptual development has relied heavily on the preferential-looking and habituation paradigms. Despite the obvious advantages of employing standardized methodologies, there is a need to study how perceptual variables give rise to and guide action beginning in the neonatal period. It is argued here that, in the first 5 months of life, it is important to distinguish reflexive patterns of movement from voluntary and cortically controlled patterns. Some criteria are defined. This paper describes three experiments which utilized movement counters to record developmental changes in the frequency and synchrony of limb movements in infants under 5 months. The results show that there is a general increase in frequency of limb movements from 1 to 5 months, but with a plateau or even a decrease in activity from the middle of the third month to the end of the fourth month. It was also demonstrated that synchrony scores (co-activation) for pairs of limbs showed significant increases from 1 month to 5 months. Finally, in all three experiments the presentation of an attractive toy resulted in suppression of activity. The results of the three experiments are interpreted to measure a gradual increase in cortically controlled movement patterns.
