Introduction. There are two opposite theoretical descriptions of visual perception: constructivist and ecological. To solve the issue of whether the perception of visual illusions is the result of a decision or whether such perception is natural and can be described using an ecological approach, an experiment was conducted to find differences in an illusory and nonillusory context, which reflects the novelty of this study. Methods. The subjects were offered a series of paired images in which it was necessary to find the difference as quickly as possible. The images could be the same: One picture could be 10 % larger than another, or, due to the illusory context, one picture could seem larger than another, and the image size was subjectively distorted due to the illusion of Ponzo and Delboeuf. According to the instructions, the size difference (real or apparent) should be ignored, and it was necessary to look for other differences. The time and precision of the response were measured for each option. Results and Discussion. Significant differences in visual field search time were found for images with an illusory difference, a real difference in size, and identical ones. For the first time, it was found that the problem is solved more efficiently (faster and more accurately) in the presence of two exact images, and the lowest efficiency is observed when solving a problem with an illusory difference in the size of images. It is concluded that the illusory context has an additional inhibitory effect on the process of solving the problem of finding differences. The advantage of describing the perception of visual illusions using a constructivist approach is experimentally shown.
