Proposed by Baddeley and Hitch in 1974, this model serves as an alternative to the more linear Atkinson-Shiffrin model. It conceptualizes short-term memory as a dynamic, multi-component working memory system. A key distinction is its inclusion of a feedback loop, suggesting a more interactive relationship between short-term and long-term memory. The model features a central executive that manages several specialized short-term systems: the visuospatial sketchpad for visual data, the phonological loop for auditory and written material, and the episodic buffer, which integrates information. This structure facilitates the active processing and manipulation of information before its potential transfer to long-term memory.
