) from distributed EEG patterns emerging in a late window (∼600-1000 ms), with primary contributions from frontal-central and central-parietal electrodes. Furthermore, single-trial LMMs showed that larger frontal Late Positive Potential (LPP) predicted lower liking after receiving likes, whereas smaller frontal LPP amplitudes predicted lower liking and slower readiness after receiving dislikes. These findings unpack the valence-specific adjustment patterns individuals employ in online contexts and their underlying dynamic neurocognitive mechanisms, demonstrating that late-stage cognitive control and regulatory processes are crucial for shaping subsequent social actions.
