在过去的十年里，视觉错觉被反复地用来理解人类和非人类动物在视觉感知上的异同。然而，几乎所有的研究都只关注与运动知觉无关的错觉，到目前为止，还不清楚非人类灵长类是否感知到任何类型的运动错觉。在本研究中，我们调查了恒河猴(Macaca Mulatta)是否感知到人类最常见的运动错觉之一--旋转蛇错觉(RSI)。为此，我们设置了四个实验。在实验1中，受试者最初接受了区分静态数组和动态数组的训练。一旦达到学习标准，他们就接受了探测试验，在这些试验中，我们呈现了总体配置相同的RSI和控制刺激，只是亮度序列的顺序发生了变化，人类无法感知到明显的运动。猴子的总体表现表明，它们自发地将RSI归类为动态数组。随后，我们在相同的任务中测试了成年人类，目的是直接比较人类和非人类灵长类动物的表现(实验2)。在实验3中，我们发现猴子可以被成功地训练来区分RSI和控制刺激。实验4表明，两个阵列中亮度序列的简单变化不能解释实验3中报告的表现。这些结果表明，一些恒河猴对这种运动错觉表现出类似人类的感知，这增加了人类和非人类灵长类动物之间运动感知的神经认知系统类似的可能性。
During the last decade, visual illusions have been used repeatedly to understand similarities and differences in visual perception of human and non-human animals. However, nearly all studies have focused only on illusions not related to motion perception, and to date, it is unknown whether non-human primates perceive any kind of motion illusion. In the present study, we investigated whether rhesus monkeys (Macaca mulatta) perceived one of the most popular motion illusions in humans, the Rotating Snake illusion (RSI). To this purpose, we set up four experiments. In Experiment 1, subjects initially were trained to discriminate static versus dynamic arrays. Once reaching the learning criterion, they underwent probe trials in which we presented the RSI and a control stimulus identical in overall configuration with the exception that the order of the luminance sequence was changed in a way that no apparent motion is perceived by humans. The overall performance of monkeys indicated that they spontaneously classified RSI as a dynamic array. Subsequently, we tested adult humans in the same task with the aim of directly comparing the performance of human and non-human primates (Experiment 2). In Experiment 3, we found that monkeys can be successfully trained to discriminate between the RSI and a control stimulus. Experiment 4 showed that a simple change in luminance sequence in the two arrays could not explain the performance reported in Experiment 3. These results suggest that some rhesus monkeys display a human-like perception of this motion illusion, raising the possibility that the neurocognitive systems underlying motion perception may be similar between human and non-human primates.
