The paper develops a five-task EEG battery to detect dissociable neural biomarkers of reinforcement learning and motivation, identifying distinct neural markers across multiple tasks.

This paper conducts a meta-analysis of dopamine and serotonin pharmacological manipulations in humans, finding distinct associations with reward and punishment reinforcement learning components.

This study investigates how neural activity during face processing is modulated by flanker stimuli, finding differences in early and late neural responses based on target and flanker similarity.

This study uses EEG to show that faces capture attention only when they are consciously perceived and task-relevant, not when they are subliminal or task-irrelevant.

This study uses multivariate pattern analysis on EEG data to decode conscious and nonconscious processing of fearful faces under different awareness conditions, finding that spatial location decoding requires conscious awareness and task relevance, while presence can be processed subconsciously.

This study uses EEG and a dot-probe task to show that fearful faces capture spatial attention only when consciously perceived and task-relevant, with no evidence of nonconscious processing.

The paper investigates the timing of visual awareness by analyzing fixation-related potentials during a free visual search task, finding that awareness emerges around 130 ms and emotion processing requires awareness.
