'''Adaptive Control of Thought''' (ACT*) theory is a [[human information processing]] and [[knowledge representation]] theory
Related to the distinction of declarative vs. procedural knowledge,
the critical atomic components of cognition and human memory are chunks and
productions. According to Yates (2007:32), Anderson (1996) claims the following: {{quotation| All that there is to intelligence is the simple accrual and tuning of many small units of knowledge that in total produce complex cognition. The whole is no more than the sum of its parts, but it has a lot of parts. (p. 356).
According to Yates (2007:33):
{{quotationbox|Procedural knowledge consists of condition-action (IF-THEN) pairs called productions which are activated according to rules relating to a goal structure (Anderson, 1983). Within the ACT framework, all knowledge is initially declarative and is interpreted by general procedures. Productions, then, connect declarative knowledge with behavior. Procedural knowledge represents "how to do things." It is knowledge that is displayed in our behavior, but that we do not hold consciously (Anderson & Lebiere, 1998).
As a task is performed, interpretive applications are gradually replaced with
productions that perform the task directly, a process called proceduralization. For example, rehearsing how to manually shift gears in a car is gradually replaced by a production that recognizes and executes the production. In other words, explicit declarative knowledge is replaced by direct application of procedural knowledge (Anderson, 2005). Sequences of productions may be combined into a single production, a process called composition. Together, proceduralization and composition are called knowledge compilation, which creates task-specific productions during practice. The process of proceduralization affects working memory by reducing the load resulting from information being retrieved from long-term memory.}}
See [[production system]] for some technical background.
According to ACT*, all knowledge begins as declarative information; procedural knowledge is learned by making inferences from already existing factual knowledge. ACT* supports three fundamental types of learning: generalization, in which productions become broader in their range of application, discrimination, in which productions become narrow in their range of application, and strengthening, in which some productions are applied more often. New productions are formed by the conjunction or disjunction of existing productions. (Kearsley: 1994)

ACT* theory can explain a range of learning types.
was quite popular in research on [[intelligent tutoring system]]s.

Definition

Procedure learning refers to a major learning type.

Many authors (e.g. Anderson) make a a distinction between two fundamental modes: declarative knowledge, i.e. what we know (propositions), and procedural knowledge, i.e. what we can perform (skills)
