This memory capacity allows an individual to keep information attainable and active in order to use them in various cognitive tasks. Working memory is similar to the outdated term known as short- term memory. According to the working memory approach proposed by Baddeley (1996), this immediate memory is a multipart system consisting of four components known as the phonological loop, visuospatial sketchpad, central executive, and the episodic buffer. The component in question is the central executive, which is responsible for integration of the other components. Is the central executive an essential part of working memory or is it simply a glorified homunculus?
The central executive component of working memory integrates information from the phonological loop, visuospatial sketchpad, the episodic buffer, and long- term memory. The central executive is responsible for regulation of task that includes auditory, visual, and spatial activation in the brain region known as the frontal cortex. Research was performed at the University of Pennsylvania Medical Center, to access whether the central executive truly is activated during verbal and spatial working memory tasks. A functional magnetic resonance imaging (fMRI) was used to examine specific brain activation throughout these tasks. Results show that activation in the prefrontal…
