Study Notes

Baddeley and Hitch's Working Memory Model

Baddeley and Hitch's model (1974) proposes a multi-component system for working memory, improving on the short-term memory concept.
The model's central executive is a supervisory system, controlling attention, prioritization, and integrating information.
The central executive manages two "slave systems": the phonological loop (verbal/auditory) and visuospatial sketchpad (visual/spatial).
A later addition, the episodic buffer, acts as a multimodal storage system, connecting information from slave systems to long-term memory.
The central executive is thought to be limited in capacity, crucial for complex tasks like problem-solving.
Dual-task experiments show these separate systems, with minimal interference between visual and verbal tasks.
The central executive's exact nature and neurological location remain unclear, defined broadly.
Though unspecified, the model is influential in explaining cognitive processes, exceeding the older short-term memory theory.
