Visual illusions are of particular interest to cognitive researchers because they reflect the active role of the brain in processing the world around us. Yousif and Scholl (2019) recently described a new visual experience, the one-is-more illusion, in which adult humans perceived continuous objects as longer than sets of discrete objects of equal length. In the current study, we investigated this phenomenon in human children ( ) and rhesus macaques (). Children were presented with a computerized 2-choice discrimination task and successfully selected the longer of 2 images for control trials. On trials in which 2 versions of the same image were presented (identical in length), and one was of a continuous form and the other consisted of 2 or more distinct units, children showed a bias for the continuous object. Monkeys were given the same computerized task and learned to choose the longer of 2 otherwise identical stimuli. However, monkeys did not show a bias to choose the continuous probe images as longer than the discrete images in the critical test trials with equal-length stimuli. These results are discussed in light of developmental and comparative research on related illusory experiences and perceptual mechanisms. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
视觉错觉尤其引起认知研究人员的兴趣，因为它们反映了大脑在处理我们周围世界时所发挥的积极作用。尤西夫和肖尔（2019年）最近描述了一种新的视觉体验，即“一即多”错觉，在这种错觉中，成年人会将连续的物体感知为比长度相等的离散物体组更长。在当前的研究中，我们在人类儿童（ ）和恒河猴（ ）身上研究了这一现象。儿童接受了一项计算机化的二选一辨别任务，并在对照试验中成功地选择了两张图片中较长的那张。在呈现同一图像的两个版本（长度相同）的试验中，一个是连续形式，另一个由两个或更多不同单元组成，儿童表现出对连续物体的偏好。猴子接受了相同的计算机化任务，并学会选择两个其他方面相同的刺激中较长的那个。然而，在长度相等的刺激的关键测试试验中，猴子并没有表现出选择连续探测图像比离散图像更长的偏好。我们根据对相关错觉体验和感知机制的发展和比较研究来讨论这些结果。（PsycInfo数据库记录（c）2022美国心理学会，保留所有权利）
