In simple terms, inhibitory control is the process of altering one's learned behavioral responses in a way that makes it easier to complete a particular goal. Inhibitory control is a key component of cognitive control; inhibitory control is impaired in both addiction and attention deficit hyperactivity disorder. In healthy adults and ADHD individuals, inhibitory control improves over the short term with therapeutic doses of methylphenidate or amphetamine.
