Which task primarily assesses binding of multimodal information into a single episode?

• A. Simple color discrimination
• B. Cross-modal binding task requiring integration of auditory, visual, textual information
• C. Rehearsing a list of digits
• D. Spatial navigation using landmarks alone

Answer: (B)

This item measures the binding of information from different senses into one integrated episode, which is the role of the episodic buffer in the working memory model. The cross-modal binding task requires you to bring together auditory, visual, and textual cues to form a single coherent representation, showing how separate streams are bound into one memory trace. The other tasks involve either a single modality or maintenance without cross-modal integration: color discrimination uses only visual perception; rehearsing digits relies on the phonological loop to keep information active without linking it to other types of data; navigating with landmarks alone tests spatial memory without combining multiple inputs. So, the cross-modal binding task best captures the binding of multimodal information into a single episode.
