亚历克斯是一只灰鹦鹉（Psittacus erithacus），它通过使用有声英语标签报告其颜色或物质来识别两个物体中较大或较小的物体，如果它们大小没有差异，它会说“无”。他对“什么颜色更大/更小？”的回答证明他在 50 次测试中的 32 次中看到了 Müller-Lyer 图形中的标准长度错觉，其中人类观察者也会看到这种错觉，并且只报告了两次相反的方向。当（a）箭杆上的箭头与箭杆垂直或接近垂直，（b）箭杆比箭头粗6倍，或（c）在多次曝光条件下进行测试后，他没有报告这种错觉，这也减少或消除了人类观察者的错觉。这些数据表明，鹦鹉和人类视觉系统以类似的方式处理 Müller-Lyer 图形，尽管它们各自的脑容量大小相差 175 倍。结果的相似性还表明，像亚历克斯这样具有发声能力的鹦鹉可以通过与人类受试者相似的范式进行可靠的视觉错觉测试。
Alex, a Grey parrot (Psittacus erithacus) who identifies the bigger or smaller of two objects by reporting its color or matter using a vocal English label and who states "none" if they do not differ in size, was presented with two-dimensional Müller-Lyer figures (Brentano form) in which the central lines were of contrasting colors. His responses to "What color bigger/ smaller?" demonstrated that he saw the standard length illusion in the Müller-Lyer figures in 32 of 50 tests where human observers would also see the illusion and reported the reverse direction only twice. He did not report the illusion when (a) arrows on the shafts were perpendicular to the shafts or closely approached perpendicularity, (b) shafts were 6 times thicker than the arrows, or (c) after being tested with multiple exposures conditions that also lessen or eliminate the illusion for human observers. These data suggest that parrot and human visual systems process the Müller-Lyer figure in analogous ways despite a 175-fold difference in the respective sizes of their brain volumes. The similarity in results also indicates that parrots with vocal abilities like Alex's can be reliably tested on visual illusions with paradigms similar to those used on human subjects.
