Working Memory Model

Working Memory Model

Proposed by Baddeley and Hitch 1974.

Short-term memory is referred to as the working memory. The working memory is a mental workspace which provides a temporary place for relevant information used for cognitive tasks. The information can decay when these cognitive tasks are completed.

The model also claims that the working memory consists of several, different structures for different processes.

Examples of Different Structures

1. Visual Memory | Visuospatial Sketchpad
2. Auditory Information | Phonological Loop

Visuospatial Sketchpad

Responsible for the visual component of the working memory, also referred to as the inner eye.

Works as a temporary storage for visual information from both sensory memory and the LTM. It helps us remember visual information and its whereabouts.

Phonological Loop

Responsible for the auditory component of the working memory and is divided into two components.

First component, the articulatory control system holds information in a verbal form. It’s responsible for holding words ready for a cognitive task.
Second component, the phonological store or inner ear holds auditory traces which can only beheld for 1.5-2 seconds if not rehearsed by the articulatory control system.
