vizualiosios

Vizualiosios, also known as visual illusions, are optical phenomena that trick the human visual system into perceiving something that is not actually there or that is different from reality. These illusions can be categorized into several types based on their underlying mechanisms. One common type is the perceptual illusion, where the brain misinterprets visual information. For example, the Müller-Lyer illusion involves two identical horizontal lines, one with inward-pointing arrows and the other with outward-pointing arrows, appearing to be of different lengths. Another type is the physiological illusion, which occurs due to the physical properties of the eye and brain. The afterimage illusion is a classic example, where staring at a bright light for a short period and then looking at a white surface can produce a negative image of the light. Visual illusions are not just entertaining; they also serve as valuable tools in scientific research, helping psychologists and neuroscientists understand the workings of the visual system.
