What is the role of Long-Term Memory in the Working Memory Model?

• A. LTM stores only spatial information.
• B. LTM operates independently of WM with no interaction.
• C. LTM replaces the Central Executive.
• D. LTM interacts with the Episodic Buffer to store and retrieve integrated episodes; LTM provides knowledge that guides WM processing.

Answer: (D)

Long-term memory supports ongoing processing by providing knowledge and content that WM uses to interpret and respond to tasks. In the Working Memory Model, the Episodic Buffer acts as a bridge, allowing integrated episodes to be formed from information in WM and relevant knowledge from LTM. This means LTM contributes stored knowledge—facts, meanings, schemas, and prior experiences—that guide how the central executive directs attention, selects strategies, and chunks information to make processing more efficient. Information from LTM can be retrieved into WM to be manipulated or combined with new input, and the Episodic Buffer helps store these integrated episodes for short-term use, bridging the gap between temporary work and long-term knowledge.

LTM stores more than just spatial information, including semantic and episodic content, and it does not operate in isolation from WM—the two systems continually interact. The central executive remains the controlling system, not something replaced by memory stores.
