多维标度用于检查新生儿对频率变化的反应的一致性。 0 日龄和 4 日龄的鸡呈现出 500、525、551、578 和 608 Hz 的五种纯音对之间所有可能的过渡。受试者习惯于一种刺激，并在改变刺激频率后测量他们正在进行的窥视的无条件延迟的持续时间。这些延迟的持续时间可以用来衡量不同动物如何感知两个频率。缩放解决方案表明，在 0 到 4 天龄之间出现了非随机的、类似成人的频率排序。
Multidimensional scaling is used to examine the consistency of neonates' responses to frequency changes. Chickens at 0 and 4 days of age were presented with all possible transitions between pairs of five pure tones at 500, 525, 551, 578, and 608 Hz. Subjects were habituated to one stimulus, and the duration of an unconditioned delay in their otherwise ongoing peeps was measured after the frequency of the stimulus was changed. Durations of these delays can be used as measures of how different animals perceive two frequencies to be. Scaling solutions show that a nonrandom, adult-like ordering of frequencies emerges between 0 and 4 days of age.
