Estimador de Carga Cognitiva — Fórmula

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)

    Ejemplo Resuelto

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

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