central executive 

NEUROLOGY, PSYCHOLOGY

A component of the working memory model of Baddeley (Clarendon, 1986), who regarded it as a temporary store of information about the expected inputs during a sequence of actions, the intermediate products of cognitive activities such as language comprehension and the goals of a current activity.

The central executive is thought to be responsible for the selection, initiation, and termination of processing routines–e.g., encoding, storing, retrieving. Damage to the frontal lobes may compromise central executive functions and, per Baddeley, cause dysexecutive syndrome.

Synonyms SAS, supervisory attentional system (Norman and Shallice, 1980)
