I already test designs for accessibility with users of screen readers, magnifiers and switch navigation. We recruit for this through a platform called Fable, which is specific to testers who use assistive technologies.
I am starting to think about how we might recruit test participants who are autistic or severely dyslexic or have some other neuroatypical condition. These people may not use an assistive technology but may have specific usability needs that neurotypical users don't have.
What is the best way to write screening questions to recruit neurodiverse participants on UserTesting.com (or another similar platform)?
