Cognitive Ability Measures for Accessible Web Content
"... far less attention has been paid to designing for users with cognitive deficits. In order to address this, we present an orthogonal set of cognitive ability dimensions based in modern neuroscience, the SCEMA model, which designers may use to characterize an individual user and help better inform accessible design ..."
The Impact of Moving Around and Zooming of Objects on Users’ Performance in Web Pages: A Cross-Generation Study
"Some common guidelines for Web content or page designs make it difficult or impossible for people with certain cognitive or visual disabilities to read moving text quickly enough." "With this in mind, experiments were conducted on 24 people in their twenties and thirties in Yokosuka-shi, Japan and on 18 elderly people in Beijing, China."

Web accessibility design recommendations for people with cognitive disabilities
"Twenty existing Web design guidelines from Web accessibility experts, government and advocacy organizations were identified in an extensive literature review for subsequent analysis. Criteria for inclusion in this analysis were that each guideline addressed some type of cognitive disability and included specific design recommendations."
Accessible Website Content Guidelines for Users with Intellectual Disabilities
"The usability of two versions of a website (a non-adapted site and a site that was adapted on the basis of easy-to-read guidelines) was tested with two groups of 20 participants. One group had intellectual disabilities but could read, the other group had no identified intellectual disabilities. In a 2 × 2 experimental design, it was investigated whether the easy-to-read website was indeed better accessible and usable for the participants with intellectual disabilities.Results The adaptation of the website worked well for participants with intellectual disabilities. Users without identified intellectual disabilities were as effective with the adapted site as they were with the non-adapted site.Conclusion The results form an empirical basis for recommendations about applying guidelines for easy-to-read text on websites for people with intellectual disabilities."
