Autism can be detected with a special type of visual test, new research shows.
The test involves having a different image presented to each eye at the same time.
For people without autism, the image flicks back and forth in conscious awareness between the two images.
The experience involves seeing one image, then the other: psychologists call this ‘binocular rivalry’.
In people with autism, though, this process is slower, with the brain taking longer to switch between the images presented to each eye.
The reason is that the brains of autistic people likely have more difficulties in inhibiting neural signals.
This helps to explain the hypersensitivity that is characteristic of autism, along with the differences in the binocular rivalry test.
