Impulse control is also critical. Specifically, this involves the linking of representations of events with memories or expectations of punishment. The person can consider the negative consequences of an intended action and inhibit or alter the action accordingly. People with poor impulse control often do poorly on neuropsychological tests that measure executive functions like abstraction, set switching, and planning. Impulse control is mediated by the orbital frontal cortex, which lies on the underside of the frontal lobe.
