# Definition of cognitive load

Wikipedia's page on cognitive load starts with

In cognitive psychology, cognitive load refers to the effort being used in the working memory. Cognitive load theory differentiates cognitive load into three types: intrinsic, extraneous, and germane. [...]

The page does not seem well written because it quickly gets to odd specifics like:

High cognitive load in the elderly has been shown to affect their center of balance.[5]

Is that first quote a good definition or is too narrow? Is cognitive load really all about working memory?
