Cognitive Load
The total amount of mental effort being used in working memory at any given time, which affects how effectively new information can be processed and learned.
What is Cognitive Load?
Cognitive load refers to the amount of mental effort required to process information. Our working memory has limited capacity, and when cognitive load exceeds this capacity, learning suffers.
Types of Cognitive Load
| Type | Description | Example |
|---|---|---|
| Intrinsic | Complexity of the material itself | Calculus is harder than arithmetic |
| Extraneous | Poor design adding unnecessary load | Confusing interface, irrelevant info |
| Germane | Effort that helps learning | Making connections, organizing |
Why It Matters for Learning
When cognitive load is too high:
- Information doesn't stick
- Learners feel overwhelmed
- Errors increase
- Motivation drops
When optimized:
- Learning flows naturally
- Retention improves
- Engagement increases
Reducing Cognitive Load
- Chunk information - Break into smaller pieces
- Remove distractions - Minimize extraneous load
- Use visuals - Pictures process differently than text
- Build on prior knowledge - Scaffolding reduces intrinsic load
- Provide structure - Clear organization helps processing
ScrollEd's Approach
AI smart scrolling is designed around cognitive load theory:
- Bite-sized cards reduce intrinsic load
- Clean interface minimizes extraneous load
- Connections and summaries support germane load
Key Takeaway: Your brain is powerful but has bandwidth limits. Smart learning design respects these limits.
