Working Memory Model

Stores a limited number of speech-based sounds for brief periods.

Two components:

Phonological Store -

• "inner ear", holds speech based information for 1-2 seconds.
• spoken words enter directly, written converted to articulatory code

Articulatory Control Process -

• Acts as "inner voice", allows sub-vocal repetition of information held in the phonological store (which can be suppressed)
• Also converts written material to articulatory code

• Drives the whole system and is involved in decision making and problem solving
• Controls attention and plans and synthesizes information from all subsidary systems and LTM
• Can ensure only most important stimuli are processed
• Flexible and can process information from any modality
• Has limited storage capacity

• Stores and processes information in visual and spatial form (what things look like and place in visual field)
• Has a limited capacity
• "Inner eye"
• Displays and manipulates memories from LTM

• Intergrates and manipulates material
• Limited capacity
• Capable of inegrating information from different sorces into chunks
• Inergrates material from LTM to meet requirements of working memory
