Infant development scales provide a one time measure of the number of scale items an infant performs and his standing relative to his age group. Repeated assessment indicates how many more items he can perform and whether his relative status has altered but does not measure actual changes in the same behaviors as development progresses. This paper discusses the importance of continuously measuring the same behavior over time as an alternative strategy. The developmental information is exemplified by the behavioral records of two infants observed over a 25-week period for changes in frequency and duration of three prone position motor responses.
婴儿发育量表提供了对婴儿完成的量表项目数量及其相对于同龄人群体所处位置的一次性测量。重复评估表明他还能完成多少更多项目以及他的相对地位是否发生了变化，但并不能衡量随着发育进程相同行为的实际变化。本文讨论了随着时间持续测量相同行为作为一种替代策略的重要性。通过对两名婴儿在25周期间进行观察，记录其三种俯卧位运动反应的频率和持续时间变化，以此举例说明发育信息。
