Cognitive Load/KOG-ni-tiv LOHD/
The total mental effort used at a given time; high load can overwhelm working memory and regulation.
Andy says:
It’s like tabs in your brain’s browser. Too many open—and everything slows.
Detailed Explanation
Cognitive load includes intrinsic (task complexity), extraneous (how info is presented), and germane (learning/structuring) load. Overload impairs initiation, memory, and emotional regulation. Supports reduce extraneous load, scaffold intrinsic load, and invest germane load where it matters.
Community Context
High load is common in open offices, noisy classrooms, and multitasking setups. ND‑friendly design reduces noise, ambiguity, and unnecessary choices.
Quick Tips
- Show one thing at a time; hide non‑essentials
- Use plain language, headings, bullets, whitespace
- Pair talk with visuals; provide summaries
Do / Don't
- Do: simplify inputs; chunk tasks; allow quiet focus
- Don't: stack instructions verbally without supports
Scientific Context
Cognitive Load Theory shows learning improves when extraneous load is reduced and relevant schemas are supported.
Language Notes
Related to working memory, processing speed, context switching.

Executive Dysfunction
Difficulties with a set of mental skills that include working memory, flexible thinking, and self-control.
Chunking

Accommodations
