Introduction
In today's world, it is crucial to prioritize inclusivity and accessibility in all aspects of life. While significant progress has been made in physical accessibility for disabled individuals, while still acknowledging how far we still have to go, cognitive accessibility remains an area that is still unconsidered in most designs. Cognitive accessibility focuses on ensuring that information, technology, and environments are designed to accommodate individuals with cognitive challenges, including executive function challenges, learning disabilities, health-related conditions, and many neurodivergent people. By embracing cognitive accessibility, we can create a more inclusive society that empowers and supports the diverse cognitive needs of many people.
In software, a user interface is like a joke: if you have to explain it, it's not that good.
What is Cognitive Accessibility?
Cognitive accessibility encompasses a wide range of considerations aimed at enhancing comprehension, information processing, and decision-making for disabled individuals with cognitive challenges, learning disabilities, or neurodivergent or health-related conditions like chronic health issues affecting cognition or executive function. These conditions may include dyslexia, attention-deficit/hyperactivity disorder (ADHD), Autistic people, Alzheimer's, dementia, stroke, sleep apnea, auto-immune disorders, traumatic brain injury (TBI) as well as a portion of the elderly, caregivers of young children, trauma survivors, people taking certain medications, and many other people experiencing cognitive challenges. However, the benefits extend beyond these groups, encompassing a broader range of individuals who experience cognitive challenges.
The Importance of Cognitive Accessibility - Statistics
- According to the World Health Organization, 16% of the world's population lives with a disability [1], and a significant portion of these individuals have cognitive challenges or learning disabilities.
- The National Center for Learning Disabilities reports that approximately 1 in 5 individuals in the United States has a specific learning disability that affects their cognitive processing [2], such as dyslexia or ADHD.
- The U.S. Centers for Disease Control and Prevention estimates that 12.7% of Americans have a cognitive disability with serious difficulty concentrating, remembering, or making decisions. [3]
- Some research suggests that cognitive disabilities are among the most common types of disabilities for which individuals request workplace accommodations. [4]

Practical Examples of Cognitive Accessibility
To better understand the impact of cognitive accessibility, let's consider some practical examples of interactions people have with products and services:
Online Forms
Imagine a user with dyslexia or cognitive processing difficulties trying to fill out a complex online form that lacks clear instructions, has a cluttered layout, and uses technical jargon. The user may struggle to understand the form's purpose, navigate through the fields, and provide the required information accurately. This frustration can lead to errors, abandonment of the form, or exclusion from accessing essential services.
User Interfaces
Consider a person with ADHD or executive functioning challenges trying to navigate a software application with a cluttered and overwhelming user interface. The interface may lack clear navigation paths, contain excessive visual distractions, or have complex menus and icons. These design choices can make it difficult for the user to focus, find the desired features, and complete tasks efficiently, impacting their productivity and user experience. Cognitive accessibility is a core component when we consider user experience (UX), and I'd go so far as to suggest that UX is actually a subset of accessibility.
At the end of the day, most non-technical people would rather have a feature-limited but easy to use interface, than a full-featured but difficult to use interface.
Digital Content
Think about a person with an intellectual disability or cognitive impairment trying to access online educational materials or technical articles filled with lengthy paragraphs, complex language, and dense information. The person may struggle to comprehend the content, retain key details, and engage with the material effectively. Inaccessibility of digital content hinders their learning opportunities and limits their access to valuable information.
Public Transportation
Picture an individual with cognitive challenges attempting to navigate a busy train station with unclear signage, complex schedules, and a lack of simple visual cues. The person may experience confusion, anxiety, and difficulties following the directions, resulting in missed connections or getting lost within the transportation system. Improved cognitive accessibility in transportation environments can enhance their independence and confidence when traveling.
Financial Services
Consider a customer with cognitive disabilities trying to understand complex banking statements, credit card terms, or insurance policies that are filled with technical language, complex calculations, and overwhelming details. This lack of cognitive accessibility can lead to misunderstandings, financial mismanagement, and barriers to making informed decisions regarding their finances and insurance coverage.
E-learning Platforms
Imagine a student with a cognitive impairment or learning disability trying to engage with an e-learning platform that lacks clear organization, intuitive navigation, or interactive elements. The student may struggle to navigate through the course materials, grasp the concepts effectively, and complete assessments due to inadequate cognitive accessibility. This can impede their learning progress and academic success.
Legal Documents
Think about someone with cognitive impairments or learning disabilities trying to engage with legal documents that lack clear organization and simplified language. They may struggle to understand their rights, obligations, and the implications of the documents, hindering their ability to make informed decisions and fully participate in legal matters. Prioritizing cognitive accessibility empowers them to navigate the legal landscape effectively. [5]
These practical examples help us understand how the lack of cognitive accessibility in various products and services can significantly impact the experiences of people facing cognitive challenges.
