Cognitive Load Assessment
Assess cognitive load across three dimensions and provide actionable recommendations to reduce unnecessary burden on users.
The Three Types of Cognitive Load
Intrinsic load — complexity inherent in the task itself. A tax return is intrinsically complex. You cannot simplify the tax code. Focus: break into manageable steps, provide context, explain terms.
Extraneous load — complexity added by the design, not the task. Confusing navigation, unclear labels, inconsistent patterns, visual clutter. Focus: eliminate ruthlessly. Every instance is a fixable design failure.
Germane load — effort invested in the actual task. This is the load you WANT. The user engaging with their real goal. Focus: maximise this by removing the other two.
