Original model (no episodic buffer) Current model (with episodic buffer)ġ. A brief, interactive version of Baddeley's original model of working memory.Ģ. The addition of the episodic buffer allowed a clearer connection to be made between working memory and long-term memory. The episodic buffer is controlled by the central executive, yet it transfers information into and out of the long term store. It is seen as a place to temporarily integrate information gathered from the phonological loop, visuo-spatial sketchpad, and long-term memory. It was added to the model 25 years later. The episodic buffer was not a part of Baddley’s original model. These are not all of the functions of the central executive, and it is important to realize that it is not fully clear what the central executive is capable of. Some of the major functions involved with the central executive are the switching of retrieval plans, time sharing in multitasking, selective attention, suppressing irrelevant information, daydreaming, and temporary activation of long-term memory. The complexity of the central executive is not yet fully known. The central executive incorporates information from the phonological loop, the visuo-spatial sketchpad, the episodic buffer, and from long-term memory. The inner scribe also deals with spatial and movement information, and is involved in the planning and execution of body movements.
The inner scribe rehearses information from the visual cache and transfers information from the visual cache to the central executive. The visual cache stores information pertaining to color and visual form. There are two components to the sketchpad. It is also activated in various activities such as puzzles, mazes, and games. When a person goes from one location to another, it is the visuo-spatial sketchpad that is stimulated. The sketchpad is also used in navigation. The visuo-spatial sketchpad allows people to store images of objects and their locations. It can be fed either directly, through perception, or indirectly, through a visual image. The visuo-spatial sketchpad is responsible for processing visual and spatial information.

It also converts written material into phonological code so that it can be registered by the phonological store The articulatory control process refreshes the information in the phonological store. The phonological store holds the information for 1.5-2 seconds. The two components of the phonological loop are the phonological store and the articulatory control process. In all these tasks, sounds are being processed through the phonological loop. For example, the phonological loop is used in learning new vocabulary, problem-solving, math problems, and remembering instructions. This includes sounds that are processed in one’s mind. The phonological loop processes sounds and is responsible for speech based information. However, the current model also contains the episodic buffer. Baddeley’s original model contained three components, the phonological loop, the visuo-spatial sketchpad, and the central executive. This model assumes that each component has a limited capacity and is relatively, not entirely, independent of the others. This led to the development of Allan Baddeley’s Model of Working Memory. According to this approach, working memory is a system with several different parts that control the information being processed. In an attempt to better understand working memory, Alan Baddeley developed the working memory approach. This memory lasts for less than a minute and is limited in capacity. Working memory, previously referred to as short-term memory, refers to the memory that one is currently processing.
