The Central Executive: Supervisory over two slave systems, processes and filters sensory information (modality-free) from the sensory register; limited capacity (4), can divide, focus, and switch attention, acting as a control system, but has no storage
The Visuospatial Sketchpad (VSSP): Slave system temporarily manipulates visual and spatial information, used for mental rotation tasks and giving directions; passive storage is Visual Cache (“Inner Eye”) and active is “The Inner Scribe”
In 2000, Baddeley added a fourth component: The episodic buffer; transfer system between components and LTM enables tasks combining visual and verbal information; maintains time sequencing and links to cognitive processes (do NOT refer to if asked to explain the 1974)
