cognitive load

This term originates from educational psychology and human-computer interaction to describe the mental strain placed on the working memory. It is typically used in professional, academic, or technical contexts to discuss efficiency, learning, and user experience design.

In practical application, the term is often paired with adjectives like intrinsic, extraneous, or germane to specify whether the mental effort is inherent to the task or caused by poor presentation. It is almost exclusively used as an uncountable noun in these contexts, referring to a general state of mental demand rather than individual units of effort.
