Cognitive control
What is Cognitive Control?
Cognitive control (also called executive control) is the set of neural processes that enable goal-directed behavior by overriding automatic responses, maintaining task rules in working memory, and flexibly switching between tasks.
How it works
Miller and Cohen proposed that prefrontal activity maintains representations of goals and helps guide processing in other brain regions. Research often distinguishes inhibition (restraining a dominant response), working memory (maintaining task-relevant information), and cognitive flexibility (changing task or approach). Their boundaries and interactions remain topics of study.
Applied example
Consider a hypothetical card-sorting task. First, sort cards by color, even though each card also has a shape.
- Keeping “sort by color” in mind illustrates maintaining a rule.
- Resisting the competing tendency to group matching shapes illustrates inhibition.
- When the instruction changes to “sort by shape,” abandoning the old rule illustrates cognitive flexibility.
These demands can overlap; the example separates them for explanation rather than measuring three processes independently.
Why it matters
Cognitive control helps explain flexible, goal-directed action. In the sorting example, a clear rule displayed beside the cards and a quiet workspace create different demands from an instruction held in memory amid interruptions. An error after the rule changes could reflect continued use of the old rule. It would not, by itself, show that a fixed supply of willpower had run out.
