What are the types of optical illusions

In addition to the illusion where you have to find one different object among similar ones, there are several types of puzzles. Here's a rough list.

Geometric illusions. They include geometric shapes, such as squares, rings, and circles, which change size or shape depending on their surroundings due to perceptual deficiencies.

Ambiguous illusions. Such images can be perceived in more than one way, allowing the brain to choose between interpretations. For example, you can see either a group of disparate objects or a holistic image composed of them.

Illusions of motion. These are static images that appear to be moving. It occurs due to natural constant eye movements.

Color illusions. They are related to the way colors are perceived by the eye. For example, they show the same color differently depending on the surroundings.

Tactile illusions. Such illusions go beyond visual perception and are related to touch. An example of this is the "rubber hand" illusions when a person thinks that the rubber model of a hand placed in front of him belongs to him and can feel.

Cognitive illusions. They are based on the way the brain processes information. They include, in particular, the Stroop effect when it is difficult for us to correctly perceive the word "blue" when it is written in red.
