Formel

Cognitive Load Model

Load = Complexity x sqrt(Tasks) x Fatigue Factor

Cognitive load increases with task complexity, the number of simultaneous tasks (scaling as square root to reflect that each additional task adds less than the previous), and fatigue.

Fatigue Factor

Fatigue increases when:

Focused work exceeds 4 hours (+10% per extra hour)

Sleep was under 7 hours (+15% per hour of deficit)

Interpretation

ScoreLevel 0-30Low (room for more) 31-60Moderate (productive zone) 61-80High (error-prone) 81+Overloaded (take a break)

Lösungsbeispiel

Complexity 6, 3 tasks, 4 hours focused, 7 hours sleep.

01Fatigue factor = 1 + 0 + 0 = 1.0
02Load = 6 x sqrt(3) x 1.0 = 6 x 1.73 = 10.4
03Score = 10 (Low load)

Häufig Gestellte Fragen

What is cognitive load?

Cognitive load refers to the total mental effort being used in working memory. Too much load leads to errors, poor decisions, and mental fatigue.

How can I reduce cognitive load?

Single-task instead of multitask, take regular breaks, simplify complex tasks into smaller steps, and ensure adequate sleep.

Why does multitasking increase load?

The brain cannot truly process multiple complex tasks simultaneously. Task-switching creates overhead that increases total cognitive demand.
