Automation Disrupts, Explanations Restore: The Neural Signatures of Agency Loss and Recovery in Human-AI Interaction

This study investigates how automation and AI explanations affect the sense of agency using EEG, finding that multi-level explanations restore agency through specific neural markers.

Decoding Agency-Related Neural States During Human-AI Interaction in Autonomous Driving Using EEG and Deep Learning

This study decodes agency-related neural states from EEG during human-AI interaction using deep learning, showing that low-frequency neural activity reflects perceived control.

Choice seeking is motivated by the intrinsic need for personal control

This study shows that humans prefer choices even when they don't affect outcomes, driven by a need for personal control rather than rewards or exploration.

Controllability boosts neural and cognitive signatures of information seeking

The paper isolates the neural and cognitive signatures of information seeking by distinguishing it from changes-of-mind, finding increased attention and arousal during information seeking.

Interacting with volatile environments stabilizes hidden-state inference and its brain signatures

The paper shows that interacting with volatile environments leads to more stable hidden-state inference and distinct brain activity patterns compared to observing cues.

Choosing and learning: outcome valence differentially affects learning from free versus forced choices

The paper tests whether learning bias stems from positivity or choice-confirmation, finding stronger positive prediction errors in free-choice conditions.

Believing in one's power: a counterfactual heuristic for goal-directed control

The paper introduces a model of causal inference that explains how people perceive their causal power through counterfactual reasoning, showing it better explains behavior than alternative models.

Trading off the cost of conflict against expected rewards

The paper investigates how conflict is perceived as a cost in value-based decisions, showing that conflict can influence decision-making and learning differently depending on its source.

Focal Versus Distributed Temporal Cortex Activity For Speech Sound Category Assignment

The paper shows that speech sound categorization relies on focal neural activity in the temporal cortex, while distributed activity reflects collateral processes.
