The paper shows that zero prediction errors in reinforcement learning lead to unique psychological and neural responses, challenging the assumption that only unexpected outcomes drive belief updates.

The paper explains how phasic alertness creates an urgency signal that speeds responses but impairs decision-making by increasing competition between evidence accumulators.

This study replicates findings from Sharon et al. (2021) on taVNS effects, confirming pupil dilation but not EEG alpha power changes.
