Procedural knowledge

Procedural knowledge, also known as know-how, is the knowledge exercised in the performance of some task. Unlike descriptive knowledge (also known as declarative knowledge, propositional knowledge or "knowing-that"), which involves knowledge of specific propositions (e.g. "I know that snow is white"), that is, facts that can be expressed using declarative sentences, procedural knowledge involves one's ability to do something (e.g. "I know how to change a flat tire"). A person does not need to verbally articulate their procedural knowledge for it to count as knowledge, since procedural knowledge requires only knowing how to correctly perform an action or exercise a skill.

The term procedural knowledge has narrower but related technical uses in both cognitive psychology and intellectual property law.
