Görsel İllüzyonların Nörotipik ve Patolojik Algı Hakkında Öğrettikleri.

Visual illusions are popularly referred to as the phenomena where the eye sees something that is not there. The aim of this review is to show that illusions are not the occasional misinterpretations of the physical world. Illusions are critical to our understanding of perceptual processes. The cause of illusions can vary depending on the reflection or refraction of light, how the brain processes the information reaching the retina, or how the visual system works when perceiving depth. Illusions, which have inspired both artists and scientists, have been instrumental in our understanding of human perception and the functioning of the brain in general. At the beginning of this article, the classes that emerge from a scientific perspective will be defined in parallel with the hierarchical visual perception. Examples of illusions that inform us about the physiological (corresponding to the early stages of visual perception) processes and cognitive (corresponding to higher level stages of visual perception) strategies will be given, and the factors that may cause them will be examined. In the light of theoretical approaches and perceptual grouping concepts, I will discuss how these interpretations help us to understand the brain and human nature. Next, I will give examples of findings and applications in clinical populations to touch on the role of illusions in our understanding of visual perception in e.g. schizophrenia patients.
