Answer:
The central executive is a component of working memory in the model proposed by Baddeley and Hitch in 1974. According to this model, working memory consists of three main components: the phonological loop, the visuospatial sketchpad, and the central executive.
The central executive is responsible for coordinating and controlling the other two components of working memory. It is involved in attentional control, task switching, planning, decision-making, and other higher-order cognitive processes. The central executive is also responsible for allocating attentional resources to incoming stimuli and for regulating the flow of information between working memory and long-term memory.
Overall, the central executive can be seen as the "boss" of working memory, responsible for managing and directing the cognitive resources needed to perform complex tasks.
