四个欧洲椋鸟（Sturnus vulgaris）成功地训练，以区分一组时间配置的4音序列，从一组其他相同的4音序列，在音高下降的音调上升的全音阶。一系列的迁移测试评估他们的能力，以保持区分（a）时，在模式中的音调的强度是不同的，（B）时，模式被缩短到1，2，或3个音调。当强度值发生变化时，这种区分仍然存在，这表明表观响度不是准确表现的相关线索。当序列被缩短时，整体辨别性能下降。缩短序列的证据，绝对和相对音高知觉序列歧视。这种辨别能力部分取决于对序列中特定音高的”命名”能力，部分取决于对给定序列音高上升或下降的检测能力。结果有影响的认知过程中的串行声学模式感知的动物，音高感知的比较研究的理论指导下，包括绝对和相对音高，并寻求自然鸟鸣的功能显著的尺寸的研究。(45参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Four European starlings (Sturnus vulgaris) were successfully trained to discriminate a set of temporally configured 4-tone sequences that rose in pitch on a whole-tone scale from a set of otherwise identical 4-tone sequences that fell in pitch. A series of transfer tests assessed their ability to maintain the discrimination (a) when the intensity of the tones in the patterns was varied and (b) when the patterns were shortened to 1, 2, or 3 tones. The discrimination was maintained when intensity values changed, which indicated that apparent loudness was not a relevant cue for accurate performance. When sequences were shortened, overall discrimination performance diminished. Shortened sequences produced evidence for both absolute and relative pitch perception in sequence discrimination. The discrimination depended in part on the ability to" name" particular pitches in the sequences and in part on the ability to detect that a given sequence rose or fell in pitch. Results have implications for cognitive processes in serial acoustic pattern perception by animals, for a comparative study of pitch perception guided by theories encompassing absolute and relative pitch, and for research seeking the functionally significant dimensions of natural birdsong.(45 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
