Which component of the WMM is primarily responsible for integrating features from different sources into an episodic representation?

• A. Central Executive.
• B. Phonological Loop.
• C. Episodic Buffer.
• D. Visuo-Spatial Sketchpad.

Answer: (C)

The idea being tested is how different types of information are combined into one coherent, time-ordered representation in working memory. The component that handles this integration is the Episodic Buffer. It serves as a temporary, multimodal store that can collect input from the phonological loop (verbal information) and the visuo-spatial sketchpad (visual and spatial information) and bind them into a single episodic representation. This binding also allows interaction with long-term memory to create richer, meaningful events. Because it can hold and merge information from multiple sources at once, the Episodic Buffer is the part of the model that creates integrated episode-like memories, rather than keeping the streams separate. The Central Executive oversees attention and coordination, but it is the Episodic Buffer that performs the actual cross-modal integration into a unified episode.
