What is the Working Memory Model and its components?

• A. A model of long-term memory with semantic and episodic stores.
• B. A model of sensory memory only.
• C. A model of short-term memory consisting of central executive, phonological loop, visuospatial sketchpad, and episodic buffer.
• D. A model of schema-based encoding.

Answer: (C)

The Working Memory Model treats short-term memory as a multi-component system that not only holds information briefly but also actively manipulates it. It divides the mind’s temporary workspace into specialized parts, all coordinated by a central control mechanism. The central executive is like the attention boss. It decides what to focus on, allocates processing resources, switches between tasks, and coordinates the activities of the other subsystems. It doesn’t store much itself, but it guides how information is processed. The phonological loop handles verbal and auditory information. It has a phonological store that holds spoken words briefly and an articulatory rehearsal process that refreshes those items through inner speech. This helps explain why shorter, easier-to-repeat words are remembered better than longer ones—the loop can rehearse them more quickly. The visuospatial sketchpad deals with visual and spatial information, such as images, locations, and relationships between objects. It supports tasks like mental rotation or keeping track of where things are in a room. The episodic buffer, added later to the model, acts as a temporary store that integrates information from the phonological loop, the visuospatial sketchpad, and long-term memory into coherent episodes. It has a limited capacity and helps create a sense of unified events or experiences you can relate to when thinking about them later. This combination—central executive plus the phonological loop, visuospatial sketchpad, and episodic buffer—captures how short-term memory operates as a dynamic, multi-faceted system rather than a single storage unit. The other descriptions refer to different memory ideas (like long-term memory stores, sensory memory, or encoding schemas), which don’t match this integrated short-term system.
