Tricky Topics: Baddeley & Hitch Working Memory Model

Understanding Working Memory

Overview of Working Memory

• Working memory, often called short-term memory, is the active system that processes and manipulates information.

• Dr. Alan Baddeley proposed a model of working memory consisting of four key components: phonological loop, visuospatial sketchpad, episodic buffer, and central executive.

Components of Working Memory

Phonological Loop

• The phonological loop is responsible for auditory processing; it allows individuals to repeat information verbally in their minds.

Visuospatial Sketchpad

• This component enables mental visualization and spatial awareness, helping individuals create mental maps and visualize locations or objects.

Episodic Buffer

• The episodic buffer temporarily stores information retrieved from long-term memory for integration with new data.

Central Executive

• The central executive oversees the other components, managing attention allocation and integrating information from both working and long-term memory.

Application of the Model

• An example illustrates how these components work together: when adding 87 plus 36, the phonological loop helps retain numbers through repetition while the episodic buffer recalls addition strategies learned previously. The central executive integrates this information to solve the problem effectively.
