学习识别复杂的感官信号可以改变它们的感知方式。欧洲八哥（Sturnus vulgaris）通过鸣叫来识别其他八哥，鸣叫由一系列复杂的、刻板的图案组成。歌曲识别学习伴随着次级听觉区域的可塑性，这表明感知学习也参与其中。在这里，为了研究感知学习是否可以在行为上观察到，使用相同-不同的操作任务来测量椋鸟如何感知主题结构的微小差异。接受过识别同种歌曲训练的鸟类能够更好地检测它们所学歌曲的主题变化，尽管这种变化对于学习联想任务来说并不是直接必要的。随着参考刺激被重复多次，歧视也得到改善。对不同主题之间更大差异的感知并未受到训练的影响。这些结果表明，当椋鸟学会识别歌曲时，主题的感官表征会得到增强。
Learning to recognize complex sensory signals can change the way they are perceived. European starlings (Sturnus vulgaris) recognize other starlings by their song, which consists of a series of complex, stereotyped motifs. Song recognition learning is accompanied by plasticity in secondary auditory areas, suggesting that perceptual learning is involved. Here, to investigate whether perceptual learning can be observed behaviorally, a same-different operant task was used to measure how starlings perceived small differences in motif structure. Birds trained to recognize conspecific songs were better at detecting variations in motifs from the songs they learned, even though this variation was not directly necessary to learn the associative task. Discrimination also improved as the reference stimulus was repeated multiple times. Perception of the much larger differences between different motifs was unaffected by training. These results indicate that sensory representations of motifs are enhanced when starlings learn to recognize songs.
