Researchers are studying a unique optical illusion to better understand Autism Spectrum Disorder (ASD).

The illusion features black and white dots that can either appear as two sheets moving in different directions or as a spinning column.

This difference in perception reveals how people process visual information. “If you view the dots as two separate sheets…you are picking each out as distinct details”—a trait commonly linked to ASD. People who see a spinning column tend to interpret the image as a whole system.

ASD is a neurodevelopmental disorder characterized by challenges in social interaction, communication, and repetitive behaviors. According to the CDC, about 1 in 36 U.S. children were diagnosed with ASD as of 2020. While many traits are linked to autism, having a few doesn’t mean someone is on the spectrum. However, understanding these traits can lead to earlier diagnosis and better outcomes.

One major trait associated with ASD is extreme attention to detail. Many individuals with autism focus more on specific elements rather than the bigger picture. This cognitive style can influence everything from learning to how visual scenes are interpreted.

This simple illusion, therefore, may provide valuable clues into how autistic brains function, opening up new possibilities for early detection and support.
