sci.cognitive-load-working-memory Calculator
Calculates working memory load from the number of chunks and Miller's 7±2 rule, and estimates cognitive load relative to available capacity. Working memory capacity: 7±2 items (Miller) or 4 chunks (Cowan) — instructional design and UI information architecture should respect this fundamental constraint.
Inputs
Chunks
Count of items or occurrences.
Familiarity Pct
Reference formula or conversion factor shown for context.
Modality
Reference formula or conversion factor shown for context.
