## At a Glance

This research answers one question:
**How can an AI assistant communicate with a dyslexic developer
without causing text burnout and cognitive overload?**

The answer splits into two halves:

1. What the **AI** should do differently in its output
2. What the **user** can configure in their tools and environment

Every recommendation is sourced.
Confidence ratings follow each finding.
Knowledge gaps are documented honestly.

## Part 1: What Causes Cognitive Overload

### 1.1 Working Memory is the Bottleneck

The human brain holds 5 to 9 chunks of information at once.
That is the hard limit.
When reading demands too much decoding effort,
there is no working memory left for comprehension.

Dyslexic readers spend more cognitive effort on decoding text.
Between 20% and 50% of people with dyslexia have weak working memory,
compared to 10% in the general population.

**Practical meaning**: Every unnecessary word, every dense paragraph,
every formatting inconsistency steals working memory
from the actual content.

**Confidence: HIGH** (3 independent sources, consistent findings)

### 1.2 Dense Text Triggers

These specific text patterns cause the most cognitive load for dyslexic readers:

- **Long paragraphs** (over 50 words) without visual breaks
- **Long sentences** with multiple clauses joined by "and," "but," "which"
- **Justified text** (uneven word spacing makes tracking harder)
- **Lines longer than 70 characters** (eye tracking breaks down)
- **Low contrast** between text and background
- **Walls of text** without headings, bullets, or white space
- **Inconsistent formatting** (different patterns for similar content)
- **Jargon and abbreviations** without explanation

**Confidence: HIGH** (3 high-trust sources, cross-referenced)

### 1.3 How Dyslexic Readers Process Differently

People with dyslexia use a fundamentally different visual sampling strategy.
They process text more sequentially, not simultaneously.

One key finding: when illustrations are added alongside text,
dyslexic adults actually perform **worse** on comprehension.
They spend only 1% of viewing time on pictures (vs 1.7% for controls)
and delay first picture fixation to 41 seconds (vs 16 seconds).

This means: simply adding images to text does not help.
The images become a distraction, not an aid.

**What does help**: structured visual representations
that **replace** text rather than accompany it.
Think: a flowchart instead of three paragraphs,
not a decorative image next to three paragraphs.

## Part 2: Typography and Layout Rules

These are the evidence-based formatting rules.
They apply to AI output, documentation, and any text a dyslexic developer reads.

### 2.1 The Rules (Summary Table)

| Element | Recommendation | Source |
|---------|---------------|--------|
| Font | Sans-serif: Arial, Verdana, Calibri, Lexend | BDA, W3C |
| Font size | 12-14pt (16-19px) minimum | BDA |
| Line spacing | 1.5x minimum | BDA, WCAG |
| Line length | 60-70 characters max | BDA, WCAG |
| Paragraph length | 50 words max, then break | W3C COGA |
| Sentence length | One idea per sentence | W3C COGA |
| Alignment | Left-aligned, never justified | BDA |
| Background | Light tint (not pure white) | BDA |
| Contrast | Dark text on light background | WCAG |
| Lists | Use bullets for 3+ items | W3C COGA |

### 2.2 Fonts: What the Evidence Actually Says

**The short version**: specialized "dyslexia fonts" are not magic.
Standard sans-serif fonts with good spacing work just as well or better.

**OpenDyslexic** has mixed evidence:

- It does NOT improve reading speed or accuracy.
  Participants preferred Verdana or Helvetica.
- It MAY improve reading comprehension for longer texts.
- A 2023 study found it helped prosodic reading (rhythm and expression).

**Lexend** has stronger evidence:

- Created by Dr. Bonnie Shaver-Troup based on research into crowding effects.
- In controlled experiments, students reading Lexend scored ~20% higher
  on words-correct-per-minute vs Times New Roman (p = 0.014).
- Benefits extend beyond dyslexia to fatigued or anxious readers.

**Best practice**: Use any clean sans-serif font with increased spacing.
Lexend, Verdana, or Calibri are strong choices.
Do not rely on a "dyslexia font" as a silver bullet.

**Confidence: HIGH** (4+ sources, peer-reviewed, mixed but clear pattern)

### 2.3 Color and Background

The evidence on colored overlays is mixed, but the pattern is clear:

- Pure white backgrounds cause more visual stress than tinted ones.
- The optimal tint varies by individual (cream, light yellow, light blue).
- When dyslexic children choose their own overlay color, reading speed increases ~25%.
- Green and red/pink should be avoided (color vision issues).

**For AI output in terminals**: the user should configure their background.
The AI cannot control this, but it can avoid outputting content
that relies on color to convey meaning.

## Part 3: What the AI Should Do

These are concrete rules an AI assistant can follow.
They are ordered from highest impact to lowest.

### 3.1 Structure Rules (Highest Impact)

**Rule 1: Lead with the answer, then explain.**
Put the conclusion or action item first.
Follow with supporting detail.
Never bury the point at the end of a paragraph.

**Rule 2: One idea per paragraph, 50 words max.**
If a paragraph exceeds 50 words, split it.
The W3C COGA guideline is explicit about this threshold.

**Rule 3: Use headings aggressively.**
Every new topic gets a heading.
Headings are scanning anchors for readers
who cannot easily scan body text.

**Rule 4: Prefer lists over prose for 3+ items.**
A series of requirements, steps, or options
should always be a bullet or numbered list.
Never embed them in a paragraph.

**Rule 5: Use progressive disclosure.**
Show the summary first.
Offer details only when asked.
Default to the shortest useful answer.

The Nielsen Norman Group defines progressive disclosure
as showing only essential information initially,
with advanced details available on demand.
This directly reduces cognitive load.

**Confidence: HIGH** (4 sources, strong cross-reference)

### 3.2 Language Rules (High Impact)

**Rule 6: Short sentences. One clause each.**
If a sentence has more than two clauses, break it up.
This is not about dumbing down; it is about reducing decoding cost.

**Rule 7: No jargon without context.**
On first use, expand abbreviations and define terms.
Example: "CI/CD (Continuous Integration / Continuous Delivery)" not just "CI/CD."

**Rule 8: Active voice, direct address.**
"Run the test" not "The test should be run."
"You need to update the config" not "The configuration requires updating."

**Rule 9: Avoid filler and hedging.**
Cut phrases like "It should be noted that,"
"It is worth mentioning," and "As you may know."
They add decoding cost with zero information.

> - [Harvard Digital Accessibility: Dyslexia](https://accessibility.huit.harvard.edu/disabilities/dyslexia) (Harvard) - HIGH trust

**Confidence: HIGH** (3 high-trust sources)

### 3.3 Formatting Rules (Medium-High Impact)

**Rule 10: Left-align everything. Never justify.**
Justified text creates uneven word spacing.
This makes line tracking harder for dyslexic readers.

**Rule 11: Keep line length under 70 characters.**
This is a WCAG guideline (ideally 60-70 characters).
For terminal output, this means wrapping intentionally.

**Rule 12: Use white space generously.**
Blank lines between sections.
Blank lines before and after code blocks.
Blank lines between list items when items are complex.

**Rule 13: Tables for comparison, not for data dumps.**
Tables work well for side-by-side comparison (2-4 columns).
Large data tables (5+ columns, 10+ rows) are a wall of text in disguise.
Break them into smaller tables or use lists instead.

**Rule 14: Bold for emphasis, not italics.**
Italics change letterforms and reduce readability.
**Bold** preserves letterform while adding emphasis.
Never use ALL CAPS for emphasis (harder to decode).

**Confidence: HIGH** (3 high-trust sources)

### 3.4 Response Pattern Rules (Medium Impact)

**Rule 15: Offer output format choice.**
At the start of complex tasks, ask:
"Do you want the summary, the full detail, or both?"
Let the user control information density.

**Rule 16: Use signposts for long responses.**
Start multi-section responses with a table of contents.
Example: "This covers 3 areas: (1) the bug, (2) the fix, (3) the test."

**Rule 17: Separate action from explanation.**
When the response includes something to do,
put the action in a clearly marked block.
Separate it visually from the reasoning.

**Rule 18: Avoid interleaving code and prose.**
Present code blocks as complete units.
Explain before or after the code, not scattered between lines.
Interleaved explanation forces constant context-switching.

**Confidence: MEDIUM-HIGH** (3 sources; AI-specific research is thin)

### 3.5 Anti-Patterns (What Makes It Worse)

These are the "red flags" that trigger cognitive overload:

1. **The Wall of Text**: 200+ words with no heading, no bullet, no break.
2. **The Hedge Parade**: "It might be worth considering that perhaps..."
3. **The Nested Explanation**: Explaining a concept inside an explanation of another concept.
4. **The Unnecessary Recap**: Restating what the user just said before answering.
5. **The Option Avalanche**: Listing 8+ alternatives when 2-3 would suffice.
6. **The Caveat Sandwich**: Important point buried between disclaimers.
7. **The Format Salad**: Mixing prose, bullets, tables, and code in rapid succession without clear sections.
8. **The Jargon Sprint**: Using 5+ technical terms in one sentence without definitions.

**Confidence: MEDIUM-HIGH** (synthesized from multiple sources; no single study tests these specific patterns in AI output)

## Part 4: What the User Can Configure

### 4.1 Terminal and CLI Environment

**Font choices for terminals**:

- **Lexend** (if terminal supports variable fonts): best research backing
- **JetBrains Mono**: clean monospace, good letter differentiation
- **Fira Code**: monospace with ligatures, good spacing
- **Comic Mono / Comic Code**: monospace variant of Comic Sans,
  surprisingly good readability for dyslexic users

**Terminal emulators with accessibility features**:

- **Warp**: built-in accessibility settings, adjustable fonts and colors,
  WCAG-compliant default color scheme.
  Note: text-to-speech integration has known issues on macOS.
- **iTerm2**: highly configurable font, spacing, and color profiles.
- **Alacritty**: GPU-accelerated, configurable font and spacing via YAML.

**Recommended terminal settings**:

- Font size: 14-16px minimum
- Line spacing: 1.3-1.5x
- Background: off-white or light tint (not pure white or pure black)
- Cursor: block or underline (not thin bar)

### 4.2 IDE Configuration (VSCode)

**Settings to change** (settings.json):

```json
{
  "editor.fontFamily": "Lexend, 'JetBrains Mono', monospace",
  "editor.fontSize": 15,
  "editor.lineHeight": 1.8,
  "editor.letterSpacing": 0.5,
  "editor.wordWrap": "wordWrapColumn",

**Confidence: MEDIUM** (practitioner-sourced, limited peer review)

### 4.3 Browser Extensions

For reading AI output in web interfaces (ChatGPT, Claude web):

- **Helperbird**: comprehensive accessibility suite.
  Overlays, font changes, text-to-speech, reading ruler.
- **OpenDyslexic Extension**: replaces all page fonts with OpenDyslexic.
- **Dyslexia Friendly (Chrome)**: adjustable fonts, colors, spacing.
- **BeeLine Reader**: color-gradient line tracking
  (helps eyes follow lines across the page).
- **Read Aloud / Natural Reader**: text-to-speech for any web page.

**Configuration tip**: Most of these extensions allow per-site settings.

**Confidence: MEDIUM** (tool recommendations, not research-backed effectiveness)

### 4.4 AI Assistant Configuration

**Claude Code (CLAUDE.md)**: Add formatting rules directly.
The AI will follow them on every response.

Example rules for CLAUDE.md:

```markdown
## Output Formatting Rules

- Maximum 50 words per paragraph. Break longer ones.
- Lead with the answer. Explain after.
- Use headings for every new topic.
- Use bullet lists for 3+ items. Never embed lists in prose.
- One idea per sentence. No multi-clause sentences.
- Bold for emphasis. Never italics or ALL CAPS.
- Keep line length under 70 characters where possible.
- No filler phrases: "It should be noted," "As you may know."
- Separate code blocks from explanation. No interleaving.
- For complex answers: start with a 2-3 line summary,
  then provide detail in clearly labeled sections.
- Ask before producing long output: "Summary or full detail?"
```

**ChatGPT (Custom Instructions)**:
Similar rules can go in the "How would you like ChatGPT to respond?" field.

**GitHub Copilot**: Limited formatting control.
Focus on configuring the IDE display instead.

**Confidence: HIGH for approach** (directly applying BDA, W3C, and IDA guidelines to AI configuration)

## Part 5: Workflow Adaptations for Neurodivergent Developers

### 5.1 What Works

These strategies are supported by research on neurodivergent developers:

- **One-piece flow**: Work on one task at a time.
  Finish it before starting the next.
  Context-switching is more expensive for neurodivergent minds.

- **Small increments with clear completion**: Break work into pieces
  that can be finished in one session.
  Completion provides the "dopamine hit" for sustained motivation.

- **Structured agendas**: For meetings and async communication,
  provide the agenda ahead of time. Allow reflection before responding.

- **Explicit over implicit**: Written instructions, clear acceptance criteria,
  documented decisions. Never rely on "everyone just knows."

- **Text-to-speech as a reading aid**: Many dyslexic developers
  report that listening to content while reading it
  significantly improves comprehension and reduces fatigue.

> - [Neurodivergent vs Neurotypical Software Engineers](https://arxiv.org/html/2506.03840) (arXiv, 2025) - HIGH trust

**Confidence: MEDIUM-HIGH** (3 sources; some self-reported evidence)

### 5.2 What Makes It Worse (Anti-Patterns)

- **Excessive parallel work**: Multiple open PRs, multiple features.
  Forces constant context-switching.

- **Dense Slack/Teams messages**: Long paragraphs in chat
  with no formatting. Same rules apply as for AI output.

- **Assumption-based management**: Assuming limitations based on labels.
  Ask the person what helps, not what the label implies.

- **Timed reading tasks**: Code reviews with time pressure,
  reading long documents in meetings.
  Dyslexic developers need more time for text-heavy tasks.

- **Inconsistent tooling**: Different formatting, different themes,
  different conventions across projects.
  Consistency reduces cognitive overhead.

## Part 6: Knowledge Gaps

Honest documentation of what the research could NOT answer.

### Gap 1: AI Output and Dyslexia (No Direct Studies)

**What was searched**: "AI assistant output dyslexia study,"
"ChatGPT formatting dyslexia research," "LLM accessibility neurodivergent."

**What was found**: Zero peer-reviewed studies measuring
the effect of AI output formatting on dyslexic users specifically.
All AI-specific recommendations are extrapolations
from general dyslexia accessibility research.

**Impact**: The recommendations in Part 3 are sound
(they are based on established reading research)
but have not been validated in the specific context
of AI assistant interactions.

### Gap 2: Optimal Chunk Size for AI Responses

**What was searched**: "optimal response length AI accessibility,"
"text chunk size cognitive load threshold."

**What was found**: General guidelines (50 words per paragraph,
5-9 chunks in working memory) but no research
on the specific threshold where AI response length
triggers cognitive overload in dyslexic readers.

**What we can infer**: Based on working memory research,
an AI response over ~150-200 words without visual breaks
likely exceeds comfortable processing capacity.
This is an inference, not a finding.

### Gap 3: Terminal-Specific Accessibility Research

**What was searched**: "terminal emulator dyslexia research,"
"CLI accessibility study reading."

**What was found**: Product documentation (Warp, iTerm2)
but no peer-reviewed research on terminal readability
for dyslexic developers specifically.

### Gap 4: Long-Term Effectiveness of Accommodations

**What was searched**: "dyslexia accommodation effectiveness longitudinal,"
"developer productivity dyslexia tools study."

**What was found**: No longitudinal studies measuring
whether these accommodations reduce text burnout over time
in professional software development contexts.

### Gap 5: Individual Variation

All research emphasizes that dyslexia manifests differently per person.
No single set of rules works for everyone.
The recommendations here are population-level findings.
Individual testing and adjustment is always necessary.
