两只猫通过使用回避技术来测试它们感知缺失基本的能力。这些动物被训练区分上升和下降的音高序列，首先是单音，然后是多音。然后，他们通过向他们展示已知的三和弦来进行测试，这些三和弦可以产生人类对缺失的基本音的感知。在这些三和弦中，组成三和弦的频率的音高要么保持不变，要么向与丢失的基频的偏移相反的方向偏移。结果表明，动物对这些三和弦的反应与从分量频率的变化方向所预期的反应不一致，但如果假设猫是根据缺失的基频作出反应，则可以解释这一点。对其中一只猫进行的进一步测试表明，随着中心频率的升高，这种现象逐渐减少，直到6 kHz时，这种现象显然完全消失。类似的下降…
Two cats were tested on their ability to perceive the missing fundamental through the use of an avoidance technique. The animals were trained to discriminate between rising and falling pitch sequences first with single and then with multiple tones. They were then tested by presenting them with tone triads known to produce the perception of the missing fundamental in humans. In these triads, the pitch of the frequencies composing the triad either remained the same or shifted in the direction opposite the shift of the missing fundamental. The results show that the animals’ response to these triads was not in conformity with that expected from the direction of change of the component frequencies, but could be accounted for if it were assumed that the cats were responding on the basis of the missing fundamental. A further test given one of the cats indicated that this phenomenon declined progressively as the center frequency was raised, until at 6 kHz it was apparently completely absent. A similar decline in ...
