What is the primary function of the central executive in the working memory system?

The central executive plays a crucial role in the working memory system by coordinating and managing the information being processed by other components of working memory, such as the phonological loop and the visuo-spatial sketchpad. It acts as a control system that allocates attention and resources to various cognitive tasks, ensuring that information from different sources is integrated and utilized effectively. This involves the manipulation and integration of information, as well as task-switching and the management of cognitive load.

The other options focus on functions that are not aligned with the role of the central executive. For example, storing long-term memories relates to the function of long-term memory systems, which is different from the active processing role of the central executive. Enhancing sensory input is more related to sensory perception processes rather than the management of working memory resources. Similarly, acting as a sensory buffer pertains to sensory memory components, which capture and hold sensory information temporarily before it is processed further into working memory.
