What hurdles do people with cognitive disabilites face when using digital technology

- Complex interfaces and clutter: Overwhelming layouts, dense menus, and inconsistent navigation increase cognitive load and cause confusion. (ISO 9241-210; W3C WCAG 2.1) - Unclear language and instructions: Jargon, long sentences, implicit assumptions, and lack of plain-language options hinder comprehension and task completion. (Plain Language guidelines) - Memory and attention demands: Tasks that require holding steps in working memory, multitasking, or sustained attention (e.g., CAPTCHA, time-limited forms) create barriers. - Problem-solving and flexibility requirements: Nonlinear flows, ambiguous error messages, or lack of guided workflows make recovery from mistakes difficult. - Visual and perceptual challenges: Small fonts, low contrast, and information presented only visually (icons without labels) impede understanding. - Sensory overload from motion and animation: Excessive motion, flashing content, or auto-playing media distract and can trigger anxiety. - Inaccessible multimedia: Videos without captions, transcripts, or easy-to-follow summaries exclude users who rely on simplified or alternative representations. - Lack of personalization and support: Few options to simplify interfaces (reduced choices, progressive disclosure), adjust pacing, or access help (contextual hints, tutorials). - Authentication and security hurdles: Complex passwords, CAPTCHA, and multi-step verification can be especially hard to complete or remember. - Inadequate testing and representation: Design teams often lack users with cognitive disabilities in research, so solutions miss real needs.
