Designing for Optimal Cognitive Function

This session explores how design choices for digital content can either reduce or create barriers for people with and without cognitive and learning disabilities. Building on that foundation, the session begins by establishing a shared understanding of cognitive and learning disabilities, including how they may impact perception, memory, attention, language, and decision-making. Because many cognitive disabilities are not immediately visible, they are often unintentionally excluded from design decisions, thereby resulting in experiences that are confusing, disorienting, or difficult to use.

Participants will be introduced to a variety of common design frameworks, such as User-Centered Design, Human-Centered Design, Universal Design, Inclusive Design, and Universal Design for Learning. All of these frameworks emphasize the importance of deeply understanding users and designing for human difference, rather than designing for an imagined “average” user.

The session will also introduce practical guidance from the W3C’s Making Content Usable for People with Cognitive and Learning Disabilities. Participants will explore the eight core objectives from this resource, including helping users understand content, find what they need, avoid mistakes, maintain focus, and complete tasks without relying heavily on memory. The role of plain language is also emphasized as a foundational strategy for reducing cognitive load and improving comprehension for all users.

The core of the session focuses on real-world examples and demonstrations that reveal how common design patterns can unintentionally exclude users. Through a guided analysis of an example interface, participants will examine issues such as unclear roles, meaningful sequence, and the effects of incorrect language attributes on the end user. These examples highlight how even small design decisions can create significant cognitive barriers, not only for people with cognitive disabilities, but for all users navigating digital content.

Throughout the session, participants are encouraged to actively engage by identifying problems, reflecting on user impact, and applying design principles to propose improvements. The demonstrations also connect directly to relevant accessibility standards to help participants bridge the gap between technical requirements and real user experiences.

By the end of the session, attendees will have an improved understanding of how design impacts cognitive accessibility for everyone. They will also be equipped with actionable strategies to create more inclusive digital experiences that account for the needs of historically excluded users. More importantly, attendees will leave with a clear understanding that exclusion is often the result of design mismatches and that thoughtful, inclusive design can improve outcomes for everyone.
