Which component binds information from different modalities into a coherent episodic representation?

• A. Phonological Loop
• B. Visuospatial Sketchpad
• C. Episodic Buffer
• D. Central Executive

Answer: (C)

The question tests how information from different senses is combined into one unified memory trace. This role belongs to the Episodic Buffer. It acts as a temporary, multimodal storage space that can take inputs from the phonological loop (auditory/verbal) and the visuospatial sketchpad (visual/spatial) and integrate them with information from long-term memory to form a coherent episodic representation of an event. The Episodic Buffer thus creates a single, blended memory episode you can recall, bridging the gap between dedicated short-term stores and long-term memory.

The other components don’t perform this cross-modal binding. The Phonological Loop handles verbal and auditory information, the Visuospatial Sketchpad handles visual and spatial information, and the Central Executive guides attention and coordinates processing without serving as a multimodal storage buffer.
