This study shows that tagging frequency affects neural responses and cognitive performance in attention tasks using SSVEPs and ERPs.

This study examines neural processes during voluntary decisions, finding evidence accumulation and motor preparation dynamics similar to perceptual decisions.

This study investigates ERP correlates of confidence during decision formation in a perceptual judgment task and finds that higher confidence is associated with larger CPP amplitudes, independent of relative evidence.

This study uses Bayesian modeling to show that psychotic-like experiences are linked to reduced precision in prior information and increased noise in sensory processing, supporting both weaker bottom-up and top-down perceptual processes.

This paper introduces a salience-based model of reward prediction errors that simulates addictive behaviors, including reduced sensitivity to negative consequences and steeper delay discounting.

This study shows that people with tobacco use disorder misattribute non-drug cues as weaker predictors of positive outcomes compared to drug cues, supporting some but not all hypotheses of the salience misattribution model.

The paper identifies distinct electrophysiological correlates of decision confidence during and after perceptual decisions, showing different neural patterns for correct and erroneous trials.

The paper investigates how absolute evidence magnitude affects decision accuracy and confidence in perceptual judgments, finding that higher absolute evidence reduces accuracy but increases confidence.

This study compares neural activity during inhibitory control tasks between people with nicotine use disorder and non-smokers, finding differences in prefrontal and anterior cingulate cortex activity.

This study identifies a robust neural network associated with error awareness using a large fMRI dataset from a Go/No-Go task.

The paper investigates how decision-making and performance monitoring adjust after conflict in a modified Flanker task, finding changes in sensory evidence and decision processes linked to frontal theta activity.
