Memory retrieval explains dynamic effects of expectations on perceptual decisions

This paper introduces a model that explains how expectations influence perceptual decisions by integrating memory retrieval and dynamic uncertainty estimation.

When awareness outstrips performance: critical tests of subjective inflation under inattention

The paper tests subjective inflation under inattention, finding robust inflation at and above visual thresholds but not for specific features at suprathreshold levels.

Whole-Brain Causal Discovery Using fMRI

This paper introduces CaLLTiF, a causal discovery method for fMRI that improves accuracy and scalability, showing consistent causal patterns in human resting-state data.

Whole-brain causal connectivity during decoded neurofeedback: a meta study

This study investigates whole-brain causal connectivity during decoded neurofeedback and identifies network dynamics associated with performance differences.

Locus coeruleus neuromelanin predicts ease of attaining and maintaining neural states of high attentiveness

The paper uses a hidden Markov model to analyze functional neuroimaging data and shows that locus coeruleus neuromelanin levels correlate with individual differences in maintaining attention-related neural states.

A novel hidden Markov approach to studying dynamic functional connectivity states in human neuroimaging

This paper introduces a novel hidden Markov model for analyzing dynamic functional connectivity states in neuroimaging data and shows it outperforms existing methods.

Variance misperception under skewed empirical noise statistics explains overconfidence in the visual periphery

The paper shows that overconfidence in peripheral vision arises from incorrect noise estimation, specifically using symmetric priors for skewed peripheral noise.

Tuned normalization in perceptual decision-making circuits can explain seemingly suboptimal confidence behavior

The paper develops a neural network model with normalization tuning to explain dissociations between confidence and decision accuracy in perceptual tasks, validated in macaque superior colliculus.

Normal observers show no evidence for blindsight in facial emotion perception

This study investigates whether normal observers can perceive facial emotions unconsciously, finding no evidence of blindsight-like behavior in emotion discrimination.

Dissociable roles for Anterior Cingulate Cortex and Basolateral Amygdala in Decision Confidence and Learning under Uncertainty

This study investigates the roles of the anterior cingulate cortex (ACC) and basolateral amygdala (BLA) in decision confidence and learning under uncertainty using a rat behavioral task.

Superior Colliculus Neuronal Ensemble Activity Signals Optimal Rather Than Subjective Confidence

The paper investigates whether neuronal activity in the superior colliculus signals optimal or subjective confidence during decision-making tasks and finds that it reflects decision accuracy rather than subjective confidence.

Subjective inflation of color saturation in the periphery under temporal overload

The paper investigates subjective inflation of color saturation in the periphery under temporal overload and finds a significant effect of modest magnitude.

On a ‘failed’ attempt to manipulate conscious perception with transcranial magnetic stimulation to prefrontal cortex

The paper evaluates subject exclusion criteria in a TMS study and finds that their exclusion did not reduce false positives, suggesting TMS to DLPFC impairs metacognition.
