Discussion

Novel analysis of EEG and MRI demonstrates attention resolves ambiguity in object representation, indicating neural competition.

Attention is actively recruited to manage representational ambiguity when visual stimuli overlap.
Key findings reveal that attention influences object representations, enhancing clarity in ambiguous situations.
Multivariate analysis of human EEG and concurrent EEG/MRI provides insights into timing and brain-wide mechanisms.
These mechanisms show widespread involvement in both semantic and executive brain networks, highlighting their significance.

Hickey et al. (2025) studied this question.
