The central executive is a key component of the working memory model proposed by Alan Baddeley. It acts as a control system that manages and coordinates information from different sources, such as visual and auditory inputs. This system is responsible for directing attention, switching between tasks, and integrating information to facilitate decision-making. In addition to managing cognitive tasks, the central executive also interacts with the phonological loop and visuospatial sketchpad, which are other components of working memory. By overseeing these processes, the central executive helps ensure that relevant information is prioritized and effectively utilized in various cognitive activities.
