Designing for Neurodiversity & Cognitive Inclusion

Beyond Accessibility: Building for Different Ways of Thinking, Processing and Interacting

Why Cognitive Inclusion Matters Now

Neurodiversity describes the natural variation in how people think, process information, communicate and interact. It includes individuals with autism, ADHD, dyslexia, dyspraxia and other cognitive profiles, as well as those who simply experience and interpret the world differently.

Many digital products still reflect a narrow set of assumptions about how users behave. They are built for an imaginary average. Someone who thinks linearly, remembers well, filters distractions easily and reads quickly. This leaves a significant portion of the population excluded, frustrated or overwhelmed.

Inclusive design begins by acknowledging that there is no single 'normal' brain. Cognitive inclusion is not an edge case. It is central to designing for real-world complexity.

Beyond WCAG and Compliance

Accessibility is a crucial foundation. But while WCAG (Web Content Accessibility Guidelines) covers areas like contrast, navigation and keyboard support, it does not fully address cognitive needs such as executive function, attention span, working memory or sensory processing.

True inclusion goes beyond guidelines. It means asking deeper questions:

• Is this experience overwhelming?
• Is this interaction forgiving of error or distraction?
• Does the language assume a specific learning style or background knowledge?
• Are users forced to multitask, recall instructions or process lots of information at once?

Good design for neurodiversity is proactive, not reactive. It is about designing with difference in mind from the start, not retrofitting later.

1. Understand Neurodivergent Perspectives

Inclusive experiences start with inclusive research. That means talking to neurodivergent users, not just about barriers, but about strengths, preferences and what good looks like.

Different people may:

• Prefer visual over text-based information (or the reverse)
• Struggle with time pressure or rapid interaction
• Be more sensitive to clutter, animation or changes in layout
• Find certain tone of voice confusing or emotionally intense

Involving neurodivergent participants in co-design ensures that experiences reflect diverse mental models, not just neurotypical defaults.

2. Design for Clarity, Calm and Flexibility

Cognitive inclusion is supported by interfaces that reduce friction and anxiety. This includes:

• Clear, simple layouts with strong visual hierarchy
• Consistent patterns that reduce cognitive load
• Customisable features, like font size, contrast, and reduced motion modes
• Generous spacing and chunked content to avoid overwhelming the user
• Options to pause, revisit or save progress for those with attention or memory challenges

These changes benefit everyone — not just neurodivergent users. Clarity and calm are universal design values.

3. Minimise Cognitive Load

Cognitive load refers to the amount of mental effort needed to complete a task. For many users, excessive cognitive load can quickly lead to fatigue, confusion or abandonment.

To reduce load:

• Avoid requiring memory (e.g. "Remember this code" or "Go back and copy that number")
• Break long processes into manageable steps
• Use visuals and icons to support text
• Allow information to be absorbed at the user's pace
• Provide immediate, non-judgemental feedback

When tasks are mentally sustainable, users are more likely to succeed — and feel respected while doing so.

4. Language Matters

Language is a powerful design tool. For cognitive inclusion, this means using:

• Plain English and avoiding jargon
• Short sentences and active voice
• Inclusive tone that avoids assumptions
• Clear labels and helpful microcopy

Error messages, onboarding text and system feedback all have emotional and cognitive impact. Clarity reduces confusion. Gentle language reduces stress.

Tone should be informative, not condescending — supportive, not overly casual. When in doubt, test with a diverse group.

5. Design for Autonomy and Control

Many neurodivergent users benefit from environments where they can set their own pace, reduce stimulation or adjust how they interact. Designing for control includes:

• Allowing users to skip or revisit content
• Providing multiple ways to access information
• Enabling control over motion, audio and visual effects
• Avoiding time-limited actions unless absolutely necessary

Autonomy builds trust. It shows that the experience is built for the user, not for the system.

Key Insights

• Neurodiversity is a natural and valuable form of human variation
• Accessibility guidelines are a baseline, not a solution for cognitive inclusion
• Inclusive design reduces cognitive load and respects different ways of processing information
• Language, layout and interaction design all impact cognitive accessibility
• Designing for neurodiversity creates better experiences for everyone
• Ippon Australia helps teams operationalise inclusive design at scale through research, strategy and delivery

How Ippon Australia Helps Organisations Embrace Cognitive Inclusion

At Ippon Australia, we work with organisations to move beyond tick-box accessibility towards truly inclusive design that respects cognitive diversity.

Our support includes:

• Inclusive research practices that bring neurodivergent voices into discovery and testing
• Co-design workshops that centre lived experience
• Audits and recommendations for reducing cognitive load in existing products
• Inclusive design principles embedded in agile delivery and product governance
• Training sessions for teams on how to design for neurodivergent needs

We collaborate with design, product and engineering teams to create digital experiences that work for more people, in more ways. Inclusion is not just about access. It is about dignity, choice and equal experience.
