Operant-conditioning techniques were used to investigate the ability of zebra finches (Taeniopygia guttata) and Bengalese finches (Lonchura striata domestica) to detect a zebra finch or a Bengalese finch target song intermixed with other birdsongs. Sixteen birds were trained to respond to the presence of a particular target song, either of their own species (n = 8) or of another species (n = 8). The birds were able to learn a discrimination between song mixtures that contained a target song and song mixtures that did not, and they were able to maintain their response to the target song when it was mixed with novel songs. Zebra finches, but not Bengalese finches, learned the discrimination with a conspecific target more quickly and were worse at detecting a Bengalese finch in the presence of a conspecific song. The results indicate that selective attention to birdsongs within an auditory scene is related to their biological relevance.
操作性条件反射技术被用于研究斑胸草雀（Taeniopygia guttata）和白腰文鸟（Lonchura striata domestica）检测与其他鸟鸣混合的斑胸草雀或白腰文鸟目标歌声的能力。16只鸟被训练对特定目标歌声的出现做出反应，其中8只对自己物种的目标歌声做出反应，另外8只对另一个物种的目标歌声做出反应。这些鸟能够学会区分包含目标歌声的歌声混合物和不包含目标歌声的歌声混合物，并且当目标歌声与新歌声混合时，它们能够保持对目标歌声的反应。斑胸草雀能比白腰文鸟更快地学会区分同种目标歌声，并且在同种歌声存在的情况下，斑胸草雀检测白腰文鸟歌声的能力更差。结果表明，在听觉场景中对鸟鸣的选择性注意与它们的生物学相关性有关。
