Study Notes
Baddeley Working Memory Model
The Baddeley working memory model is a theoretical framework that explains how our brains process and store information temporarily. The model consists of multiple components that work together to facilitate cognitive tasks.
Phonological Loop
- Also known as the "articulatory loop"
- Responsible for verbal information processing and temporary storage
- Consists of two sub-components:
- Phonological store: a passive storage system that holds verbal information for a short duration
- Articulatory rehearsal process: an active process that rehearses verbal information to maintain it in working memory
Visuospatial Sketchpad
- Responsible for visual and spatial information processing and temporary storage
- Processes visual information, including shapes, colors, and patterns
- Involved in tasks such as mental imagery and spatial reasoning
Central Executive
- The "CEO" of the working memory system
- Coordinates the flow of information between the Phonological Loop, Visuospatial Sketchpad, and Episodic Buffer
- Responsible for attentional control, decision-making, and problem-solving
- Manages the allocation of resources between different tasks and components
Episodic Buffer
- A temporary storage system that integrates information from the Phonological Loop and Visuospatial Sketchpad
- Holds bound features of information (e.g., linking words with visual images)
- Plays a key role in the formation of new episodic memories
Working Memory Capacity
- Refers to the limited capacity of the working memory system
- Represents the amount of information that can be held and processed simultaneously
- Individual differences in working memory capacity are correlated with cognitive abilities, such as intelligence, learning, and problem-solving.

- A theoretical framework explaining how working memory functions
Phonological Loop
- Responsible for verbal information processing
- Consists of two components:
- Phonological store: temporarily stores verbal information
- Articulatory rehearsal process: repeats verbal information to maintain it in working memory
- Capacity is limited to around 1-2 seconds of speech
Visuospatial Sketchpad
- Responsible for visual and spatial information processing
- Processes visual and spatial information in working memory
- Capacity is limited, and information can be lost if not rehearsed
Central Executive
- Controls the flow of information between phonological loop, visuospatial sketchpad, and long-term memory
- Responsible for attention, decision-making, and error correction
- Has a limited capacity and can be influenced by factors such as motivation and arousal
Episodic Buffer
- Acts as a "backup" system to integrate information from phonological loop and visuospatial sketchpad
- Temporarily stores and integrates information from different sources
- Plays a crucial role in working memory tasks requiring integration of verbal and visual information
Working Memory Capacity
- Ability to hold and manipulate information in working memory
- Limited capacity, with an average capacity of around 4-6 chunks of information
- Can be improved through practice, training, and strategies such as chunking and rehearsal
Dorsolateral Prefrontal Cortex
- Region in prefrontal cortex involved in working memory
- Plays a key role in central executive system
- Damage to this region can lead to impairments in working memory and executive functions
