The Working Memory Model (WMM) revolutionizes our understanding of short-term memory by introducing a dynamic system with specialized subsystems. It includes the Central Executive, which directs attention and cognitive processes, the Phonological Loop for auditory information, the Visuospatial Sketchpad for visual and spatial data, and the Episodic Buffer for integrating multimodal information. These components work together to facilitate complex cognitive tasks and memory manipulation.

The Working Memory Model is a complex perspective on short-term memory that challenges earlier models
The Working Memory Model differs from the Multi-Store Model by emphasizing the active processing of information
The Working Memory Model consists of the central executive, phonological loop, visuospatial sketchpad, and episodic buffer
The central executive is responsible for directing attention and coordinating the activities of the other subsystems
The central executive is involved in higher-order cognitive processes such as problem-solving and decision-making
The central executive has a limited processing capacity and can only manage a few complex tasks at a time
The phonological loop is responsible for processing and temporarily holding auditory and verbal information
Phonological Store
The phonological store retains auditory information, while the articulatory rehearsal process allows for the rehearsal of this information
Importance of the Phonological Loop
The phonological loop is essential for language comprehension and retaining verbal information in working memory
The phonological loop has a limited capacity and can only maintain information for a short period of time
The visuospatial sketchpad is responsible for temporarily storing and manipulating visual and spatial information
Visual Cache
The visual cache stores static visual information, such as shape and color
Inner Scribe
The inner scribe processes spatial and movement dynamics
The visuospatial sketchpad is crucial for tasks involving visual imagination and spatial orientation
The episodic buffer serves as a temporary storage system for integrating information from different modalities
The episodic buffer acts as an intermediary between the slave systems and long-term memory, facilitating the transfer of information for use in working memory tasks
The episodic buffer is crucial for complex cognitive tasks that require the synthesis of information from various sources
