It is responsible for controlling attention, maintaining task goals, decision making, and memory retrieval, as well as distributing resources between the visual spatial sketchpad and the phonological loop. It is also dynamic in that it decides which information to attend to and which parts of working memory to send that information to be dealt with. ```mermaid flowchart LR A(Central Executive Memory) --> B(Phonological Loop) B(Phonological Loop) --> E(Phonological Store) B(Phonological Loop) --> F(Phonological Process) A(Central Executive Memory) --> C(Visuospatial Sketchpad) C(Visuospatial Sketchpad) --> G(Visual Cache) C(Visuospatial Sketchpad) --> H(Inner Scribe) A(Central Executive Memory) --> D(Episodic Buffer) ``` ### Phonological Loop This is a temporary storage that handles all of the auditory information as well as what we rehearse to say. Saying something in your head will use the phonological loop. The memory limitations here are limited roughly by how much time it takes to produce the audio. That duration is roughly **2 seconds**. #### Phonological Store Stores what is heard. #### Phonological Process Rehearses words to keep them in working memory. ### Visuo-spatial Sketchpad As the name implies, this area is where we store the pictures and images associated with the memory. #### Visual cache Stores visual data like shape and color #### Inner Scribe Records the arrangement of objects and transfers information to the central executive system. ### Episodic Buffer Puts together visual and auditory information. The episodic buffer allows individuals to use integrated units of information they already have to imagine new concepts From [this article](https://pubmed.ncbi.nlm.nih.gov/34563762/), The episodic buffer is a putative component of working memory proposed to account for several short-term memory functions, including unexpectedly preserved **immediate prose recall** by amnesic patients. Over the course of time, this component has **increasingly become associated with binding functions**. From [this article](https://pubmed.ncbi.nlm.nih.gov/24830472/), Collectively, these findings suggest that ADHD-related working memory deficits reflect a combination of **impaired central executive and phonological storage/rehearsal** processes, as well as an **impaired ability to benefit from bound multimodal information processed by the episodic buffer**
