采用回避条件反射和极限法测定了4只长尾小鹦鹉的绝对听阈、掩蔽听阈和临界比。然后使用相同的程序研究另外6只动物的频差阈值。的功率谱和“语调的恒定性”的长尾小鹦鹉呼叫也进行了测量和相关的绝对和差分频率灵敏度。长尾小鹦鹉耳朵中的频率分析的机制被认为与本研究结果和鸟类和哺乳动物的听觉系统之间的解剖和功能差异。
Avoidance conditioning and the method of limits were used to measure absolute auditory thresholds, masked thresholds, and critical ratios in 4 parakeets. The same procedure was then used to study frequency difference limens in 6 additional animals. The power spectrum and "constancy of intonation" of the parakeet call were also measured and related to the absolute and differential frequency sensitivity. The mechanism of frequency analysis in the parakeet ear was considered in relation to the present results and to the anatomical and functional differences between the avian and mammalian auditory systems.
