CPACC Cognitive and Neurological Accessibility Questions and Answers 5 — Questions and Answers
Question 1: Which Web Content Accessibility Guideline addresses the need to avoid content that flashes more than three times per second to protect users with photosensitive epilepsy?
- 2.3.1 Three Flashes or Below Threshold (Correct answer)
- 1.4.3 Contrast Minimum
- 2.2.2 Pause, Stop, Hide
- 1.1.1 Non-text Content
Correct answer: 2.3.1 Three Flashes or Below Threshold
WCAG 2.3.1 Three Flashes or Below Threshold (Level A) requires that content not flash more than three times per second to prevent seizures in photosensitive users.
Question 2: A person with a traumatic brain injury (TBI) reports difficulty remembering steps after navigating away from an instruction page. Which solution BEST addresses this?
- Requiring users to memorize instructions before proceeding
- Providing persistent, always-visible step summaries or allowing the instructions page to remain open (Correct answer)
- Reducing the total number of steps to one
- Adding a timer that advances pages automatically
Correct answer: Providing persistent, always-visible step summaries or allowing the instructions page to remain open
Persistent instruction summaries or multi-pane layouts support users with TBI and memory impairments by keeping task-relevant information visible without relying on recall.
Question 3: What is a 'cognitive walkthrough' in the context of accessibility evaluation?
- A technique where evaluators simulate the thought process of a target user to identify usability barriers (Correct answer)
- A method of reviewing server-side code for performance bottlenecks
- An automated tool that scans pages for WCAG violations
- A survey distributed to users after they complete a task
Correct answer: A technique where evaluators simulate the thought process of a target user to identify usability barriers
A cognitive walkthrough is a usability inspection method where evaluators step through tasks as a target user would, identifying points of confusion and cognitive barriers.
Question 4: Which strategy BEST supports users with dyslexia when reading long-form web content?
- Using justified text alignment and dense paragraph blocks
- Providing short paragraphs, adequate line spacing, sans-serif fonts, and the option to adjust text size (Correct answer)
- Displaying all content in italicized serif fonts for emphasis
- Requiring users to scroll horizontally to access content
Correct answer: Providing short paragraphs, adequate line spacing, sans-serif fonts, and the option to adjust text size
Short paragraphs, generous line spacing, sans-serif fonts, and resizable text reduce visual crowding and letter confusion that affects readers with dyslexia.
Question 5: Under the CPACC framework, which category of disability does obsessive-compulsive disorder (OCD) fall under?
- Physical and motor disabilities
- Cognitive and neurological disabilities (Correct answer)
- Deafblindness and combined sensory loss
- Speech and language disabilities
Correct answer: Cognitive and neurological disabilities
OCD is classified as a cognitive/neurological disability because it involves neurological processes that affect thought patterns, behavior, and daily functioning.
Question 6: Which technique helps users with executive function difficulties complete multi-step online processes such as tax filing or account registration?
- Removing all navigation links to prevent distraction
- Providing clearly numbered steps, confirmation dialogs, and the ability to save progress at any point (Correct answer)
- Auto-submitting forms after a fixed time period
- Hiding optional fields to simplify visual layout without labeling them
Correct answer: Providing clearly numbered steps, confirmation dialogs, and the ability to save progress at any point
Numbered steps, progress saving, and confirmation dialogs scaffold executive function by externalizing planning, sequencing, and error-checking demands.
Question 7: Which of the following BEST describes the 'error prevention' principle as it applies to users with cognitive disabilities?
- Preventing users from submitting any form until all fields are validated in real time
- Designing systems so that mistakes are difficult to make, easy to detect, and reversible (Correct answer)
- Locking form fields after first entry to prevent accidental changes
- Removing optional form fields entirely to reduce completion errors
Correct answer: Designing systems so that mistakes are difficult to make, easy to detect, and reversible
Error prevention for cognitive accessibility means designing so errors are hard to make, clearly flagged when they occur, and simple to correct without loss of progress.
