研究了新生鸡对多维声刺激的一致反应的发展。当小鸡听到声音刺激的变化时，它们会抑制正在进行的窥视，这种抑制的程度与变化的程度有关。因此，抑制的持续时间可以解释为对刺激之间的感知差异。对不同频率、强度和重复率的5对声刺激之间的所有可能的转换所引起的抑制在2个年龄进行测量。这些数据用多维标度程序进行分析。从4天大的雏鸡到不同频率和强度的刺激子集的结果中，可解释的结构是明显的。相比之下，新生的小鸡表现出不一致的反应。两个年龄组对三维不同的刺激都没有可解释的结构反应。因此，对二维声刺激的一致反应出现在出生后的最初几天。随着动物的成熟，感知维度与频率和强度的物理维度相关联。
The development of consistent responses to multidimensional acoustic stimuli was investigated in newborn chickens. Young chicks suppress their ongoing peeps when they hear a change in an acoustic stimulus, and the amount of that suppression is related to the amount of change. Durations of suppression can thus be interpreted as perceived differences between pairs of stimuli. The suppressions elicited by all possible transitions between pairs of 5 acoustic stimuli that differed in frequency, intensity, and repetition rate were measured at 2 ages. These data were analyzed with a multidimensional scaling program. Interpretable structure is evident in the results from 4‐day‐old chicks to a subset of the stimuli that vary in frequency and intensity. Newborn chicks, in contrast, showed inconsistent responses. Neither age group responded with interpretable structure to stimuli that differed in 3 dimensions. Thus, consistent responses to 2‐dimensional acoustic stimuli emerge over the first few postnatal days. Perceptual dimensions become associated with the physical dimensions of frequency and intensity as animals mature.
