Fixation-evoked potentials reveal neural signatures of hierarchical value-integration during decision-making

This study uses EEG and eye-tracking with a computational model to identify neural signatures of value-integration during decision-making under naturalistic conditions.

Mutual inclusivity improves decision-making by smoothing out choice's competitive edge

This study shows that allowing inclusive choices reduces decision-making costs by decreasing competition between options and participant conflict.

Reinforcement learning enhances training efficiency in high-performance athletes

This study shows that reinforcement learning improves performance and strategy choices in skilled athletes compared to traditional supervised learning methods.

Dissociable neural signals for reward and emotion prediction errors

The paper investigates neural signals for reward and emotion prediction errors during social learning, finding distinct neural signatures for each.

Common neural choice signals can emerge artifactually amidst multiple distinct value signals

The paper shows that neural signals resembling evidence accumulation in decision-making can emerge artifactually from overlapping value signals, not from actual evidence accumulation processes.

Learning when effort matters: Neural dynamics underlying updating and adaptation to changes in performance efficacy

This study investigates how people update their beliefs about performance efficacy and adjust cognitive control based on these beliefs using computational modeling and EEG.

I knew that! Response-based Outcome Predictions and Confidence Regulate Feedback Processing and Learning

The paper shows that confidence in outcome predictions and their calibration to prediction precision improve learning efficiency through neural feedback processing.

Age-Related Changes in the Neural Dynamics of Bottom-Up and Top-Down Processing During Visual Object Recognition: An Electrophysiological Investigation

This study investigates age-related changes in neural dynamics during visual object recognition, finding increased top-down processing in elderly adults due to compromised bottom-up processing.

When effort matters: Expectations of reward and efficacy guide cognitive control allocation

The paper shows that people adjust their mental effort based on expected reward and the efficacy of effort, supported by EEG data.

Conceptual knowledge affects early stages of visual mental imagery and object perception

The paper shows that conceptual knowledge influences early visual processing during both object perception and mental imagery, revealing shared top-down mechanisms in low-level visual processing.

Goal congruency dominates reward value in accounting for behavioral and neural correlates of value-based decision-making

The paper investigates how goal congruency and reward value influence decision-making and neural activity, finding that goal congruency uniquely explains decision speed and brain activity patterns.

Spatiotemporally distinct neural mechanisms underlie our reactions to and comparison between value-based options

The paper investigates whether value appraisal and choice processes are temporally dissociable using EEG, finding distinct neural activity patterns for each.
