What is working memory capacity?

Miller's 1956 research established 7±2 items as working memory capacity. More recent research (Cowan, 2001) suggests 4 chunks are closer to the actual limit.

How does cognitive load affect learning?

Extraneous cognitive load (from poor design) reduces resources available for germane load (actual learning). Well-designed instruction minimizes extraneous load.

What is chunking in learning?

Chunking groups related information into larger meaningful units, effectively increasing working memory capacity. Expert chess players 'see' positions as chunks, not individual pieces.

Cognitive Load Working Memory Estimator

Formula Definitions

The Cognitive Load Working Memory Estimator works by applying a well-defined formula to the values you enter. Understanding the formula behind the calculation helps you interpret the result and check that your inputs are correct. Below we break down the key components that drive the Cognitive Load.

The core formula used by this calculator is:

Result = f(inputs, settings)

Each variable in the formula has a specific meaning:

inputs — Values entered into the Cognitive Load.
settings — Options, units, or parameters that adjust how the calculation is performed.
Result — Computed output for the chosen inputs and settings.
