我们训练虎皮鹦鹉的操作性条件反射，以区分一组接触呼叫中相同的不同的任务，并分析了响应延迟从这个任务，通过使用多维尺度（MDS）和聚类分析程序。人类听同样的叫声，并通过直接评级程序来表示成对叫声之间的相似性。MDS程序（{sindscal}）被用来安排这些复杂的声音刺激在多维空间反映知觉组织。使用多元回归技术来识别与从MDS获得的视觉维度相关的接触性呼叫的声学特征。一些光谱特征（例如，峰值频率，频率调制率，和光谱能量的浓度）出现作为重要的虎皮鹦鹉和人类，但这些线索的相对显着性不同的两个物种。对两组笼中和非笼中的鹦鹉进行的额外测试表明，呼叫的经验可以改变用于感知组织和个体识别的各种声学特征的显着性。（PsycINFO数据库记录（c）2019阿帕，保留所有权利）
We trained budgerigars by operant conditioning to discriminate among a set of contact calls in a same–different task and analyzed response latencies from this task by using multidimensional-scaling (MDS) and cluster-analysis procedures. Humans listened to the same calls and indicated the similarity between pairs of calls by a direct rating procedure. An MDS program ({sindscal}) was used to arrange these complex acoustic stimuli in multidimensional space reflecting perceptual organization. Multiple regression techniques were used to identify the acoustic characteristics of contact calls that were correlated with the peceptual dimensions obtained from MDS. A number of spectral characteristics (eg, peak frequency, rate of frequency modulation, and concentration of spectral energy) emerged as important for both budgerigars and humans, but the relative salience of these cues differed for the two species. Additional tests with two groups of budgerigars—cagemates and noncagemates—showed that experience with calls can change the salience of various acoustic characteristics used for perceptual organization and individual recognition.(PsycINFO Database Record (c) 2019 APA, all rights reserved)
