动物是否经历视觉错觉是研究不同物种视觉认知进化和运作的一个丰富领域。在这里，五只椋鸟被测试，以检查它们是否经历了艾宾浩斯-蒂琴纳错觉。在使用绝对目标圆大小辨别的两个实验中，操纵周围侧翼的大小、相似性、距离和数量。结果表明，这种雀形目物种表现出与错觉感知不一致的行为，既不是以人类的方式，也不是像第一个实验所建议的那样，是一种反向错觉。相反，用于研究这种错觉的典型训练使椋鸟学会将不相关的侧翼融入决策过程，从而排除了对错觉的研究。由此产生的区别行为可能最好使用模板匹配帐户来描述。虽然动物的错觉感知仍然是一个重要的比较问题，但它需要额外的验证来确认任何错觉报告的确切机制。
Whether animals experience visual illusions is a fertile area of study for examining the evolution and operation of visual cognition across different species. Here, five starlings were tested to examine whether they experienced the Ebbinghaus–Titchener illusion. Across two experiments using an absolute target circle size discrimination, the size, similarity, distance, and number of the surrounding flankers were manipulated. The results suggest that this passerine species exhibits behavior inconsistent with the perception of the illusion, neither in a human-like fashion nor, as suggested by the first experiment, a reversed illusion. Instead, the typical training used to investigate this illusion caused the starlings to learn to integrate the irrelevant flankers into their decision process in a manner that precludes the study of illusory perception. The resulting discriminative behavior might best be described using a template-matching account. While illusion perception by animals remains an important comparative question, it requires additional validation to confirm the exact mechanisms of any illusory reports.
