Specialists from the University of Rochester in the United States claim that the visual illusion test can help quickly identify mild autism, especially in children. The study published in Journal of Neuroscience, The fee is used as the basis for evaluation.
According to the researchers, if a person cannot easily locate the white square while focusing on the black markings, they likely have mild autism.

The study authors explain that individuals with autism process information differently. They focus intensely on one element at a time rather than looking at the picture as a whole. In this case, black marks attract more attention.
Study author Emily Knight explains that our brain collects parts of a visual object or scene to help us interact with the environment.
She claims that when viewing an image, the brain takes into account our experience to anticipate sensory stimuli, deal with ambiguity and fill in the missing information.
However, according to Knight, the findings suggest that children with autism “may not be as able to predict and fill in missing visual information as their neurotypical peers.”
Optical error and illusion
The study involved 60 children, 29 of whom were diagnosed with autism spectrum disorder (ASD).
The team used a classic optical illusion technique, involving simple lines or shapes like circles with missing parts.
When arranged in a certain way, the empty spaces line up to form a second shape in your negative space.
From the brain activity of 7- to 17-year-olds with autism, the researchers noted a delay in delusional processing.
However, the scientists point out that this does not necessarily mean that the participants were unable to perceive the shape formed by the contour images, but rather that it indicates that their brains processed the illusion in a non-automatic manner.
