绝对音高（AP）是在没有外部参照物的情况下对单个音高进行分类的能力。作者比较了鸽子（一种非鸣禽物种）和R。魏斯曼，M。涅戈万角斯特迪湖Philillmore，J. Coyle，& D. Mewhort，1998年）从斑胸草雀（Taeniopygia guttata，一种鸣禽物种）和人类（智人）在AP测试中，需要分类连续的音调到3或8个频率范围的基础上，在每个频率范围和奖励之间的相关性音调。猪的3-距离辨别的准确性与斑胸草雀和人类相似。在更具挑战性的8范围任务中，鸽子，像斑马雀一样，在所有8个范围内从奖励到非奖励的变化中区分，而人类只区分第一个和最后一个范围。结合之前的研究，目前的实验表明，鸟类可能比哺乳动物具有更准确的AP。
Absolute pitch (AP) is the ability to classify individual pitches without an external referent. The authors compared results from pigeons (Columba livia, a nonsongbird species) with results (R. Weisman, M. Njegovan, C. Sturdy, L. Phillmore, J. Coyle, & D. Mewhort, 1998) from zebra finches (Taeniopygia guttata, a songbird species) and humans (Homo sapiens) in AP tests that required classification of contiguous tones into 3 or 8 frequency ranges on the basis of correlations between the tones in each frequency range and reward. Pigeons' 3-range discriminations were similar in accuracy to those of zebra finches and humans. In the more challenging 8-range task, pigeons, like zebra finches, discriminated shifts from reward to nonreward from range to range across all 8 ranges, whereas humans discriminated only the 1st and last ranges. Taken together with previous research, the present experiments suggest that birds may have more accurate AP than mammals.
