주변의 다른 정보의 영향으로 시각 자극을 인지하는 과정에서 원래의 사물에 대한 시각적인 착각을 일으키는 것이 착시이다.
주요한 착시에는 세 가지 종류가 있다.
첫 번째는 사물의 이미지를 받아들이면서 착각을 일으키는 글자 그대로의 착시 현상이다.
두 번째는 명암, 기울기, 색상, 움직임 등의 특정한 자극의 과도한 수용으로 인해 일어나는 생리적 착시이다.
세 번째로는 뇌가 눈에서 받아들인 자극을 무의식적으로 추론하는 과정에서 발생하는 인지적인 착시이다

The pictures that magically seem to MOVE:
Stomach-churning optical illusions are so trippy they come with a health warning
The illusions were created by Professor Akiyoshi Kitaoka from the Ritsumseikan University, in Kyoto, Japan He has spent more than a decade creating illusions using trial and error, or by adapting existing designs The animal psychologist’s interest in the illusions began when he studied how the designs affect monkeys His website comes with a health warning about dizziness, sickness and epileptic seizures caused by the illusions Professor Kitaoka advises people don’t close their eyes when looking at the images as it can ‘make the attack worse’
By Victoria Woollaston
From columns that shake, to waves of colours and rotating snakes, these optical illusions should not be viewed if you've just eaten.
Each stomach-churning design was created by a former animal psychologist who became fascinated by the illusions when he studied monkeys in a neuroscience institute.
They are so powerful that each image comes with a health warning, and if you start to feel dizzy or sick cover one eye and look away - don’t close your eyes completely.

Professor Akiyoshi Kitaoka, from Ritsumseikan University, in Kyoto, Japan, has spent more than a decade creating his collection of works. The professor devised the Rotating Snake illusion (pictured) in 2003, which comes with a warning on his website, due to the feeling of nausea it could cause some viewers
WHAT IS AN OPTICAL ILLUSION
Optical Illusions use colour, light and patterns to create images that deceive or mislead the brain. The information collected by the eye is processed by the brain.
In the process of converting what it sees, the brain tries to make sense of the different colours and patterns. This creates a perception that doesn't match the image, and confuses the brain.
This is because the illusions can become more prominent, and the effect worsens, when eyes are closed completely. The images were created by Professor Akiyoshi Kitaoka, from Ritsumseikan University, in Kyoto Japan. The 52-year-old has spent more than a decade creating his collection either from scratch, or by developing existing designs.
The professor also devised the Rotating Snake illusion in 2003, which comes with a warning on his website due to the feeling of nausea it can cause some viewers.
This image is called Irrigation and it looks like rollers printed with blue dots turning towards each other in a line. Each design is either created through a process of trial and error, or based on illusion experiments of the past. Professor Kitaoka began designing the images in the mid-90s, and has created hundreds of different designs

In Rotating Rays (pictured) the central ring of squares rotates anticlockwise as the outer circles of squares move slowly clockwise. Having originally studied animal psychology, Professor Kitaoka, 52, decided to focus on optical illusions after looking into their effect on monkeys, while working at a neuroscience institute
All of his designs stem from Professor Kitaoka's interest in the brain's interpretation of signals from the eyes. Having originally studied animal psychology, Professor Kitaoka, 52, decided to focus on optical illusions after looking into their effect on monkeys, while working at a neuroscience institute. Each design is either created through a process of trial and error, or based on illusion experiments of the past. He began designing the images in the mid-90s, and has since created hundreds of different illusions.
