Technicallyâ¦ It should also be noted that the optical illusions presented in this video are only partially related to the cheerleader effect. The reality of what the brain does with human faces is too complicated to simplify into a few exercises with rectangles and circles. The rectangle/square illusion was of my own design and was made to illustrate how the brain fills in periphery information with merely fovic information, resulting in averaging.
