Key Takeaways & Core Findings

Working memory is strictly limited in capacity; poorly phrased questions cause premature cognitive overload.
Extraneous load must be systematically minimized so working memory can focus on intrinsic content complexity.
Eliminating 'hidden linguistic tricks' ensures fair assessment for diverse learners.

1. The Tripartite Architecture of Cognitive Load

Formulated by educational psychologist John Sweller, Cognitive Load Theory identifies Intrinsic, Germane, and Extraneous mental load.

In school examinations, the goal of ethical assessment design is to eliminate extraneous load caused by confusing formatting or ambiguous phrasing.
