Disentangling visual and motor contributions to continuous psychophysics

This study disentangles visual and motor contributions to tracking performance in continuous psychophysics by analyzing cross-correlogram metrics under visual impairment and hand dominance conditions.

Structural and contextual biases interact to shape duration perception

The paper quantifies structural and contextual biases in duration perception using a discrimination task and finds that Bayesian inference and rescaling explain the results.

Natural scene segmentation dynamics reveal iterative Bayesian inference

This study reveals that iterative Bayesian inference explains the spatiotemporal dynamics of natural scene segmentation by integrating visual inputs with spatial priors.

Spatial and temporal contexts drive visual temporal integration via spatiotemporal normalisation

The paper shows that visual temporal integration depends on spatial and temporal contexts, and proposes a computational model explaining these interactions.

Long-term perceptual priors drive confidence bias that favors prior-congruent evidence

The paper investigates how long-term perceptual priors influence confidence in perceptual decisions, finding that confidence is more biased toward prior-congruent evidence than perceptual decisions themselves.

Encoding and combining naturalistic motion cues in the ferret higher visual cortex

This study investigates how the ferret higher visual cortex encodes and combines complex motion cues from natural scenes, revealing a structured and distributed neural code.

Confidence judgements from fused multisensory percepts

This study investigates whether humans can access uncertainty estimates from individual sensory modalities after multisensory integration, finding that confidence judgments are influenced by the fused percept.

Given the birds, where is the flock? Visual estimation of the location of collections of points

The paper investigates how humans estimate the location of a cloud of points by analyzing performance across different statistical distributions and proposes a visual cluster model to explain this process.

The Confidence-Noise Confidence-Boost (CNCB) model of confidence rating data

The paper introduces the CNCB model to estimate confidence efficiency in perceptual decisions, offering a theory-driven alternative to existing measures.

Sensorimotor Confidence for Tracking Eye Movements

The paper investigates metacognitive sensitivity for the accuracy of eye movements by having participants judge their tracking performance of a moving dot cloud.

Crossmodal metaperception: Visual and tactile confidence share a common scale

The paper investigates whether visual and tactile confidence judgments share a common scale, finding they do with similar precision across modalities.

What confidence and the eyes can tell about interacting with a partner

This study investigates how perceptual confidence influences decision-making in human interactions, finding that confidence predicts decision changes more than task difficulty or accuracy.

Linking individual differences in cognitive control and perception: Meta-perception in older and younger adults

This study examines age-related differences in visual confidence and links them to cognitive control capacities in younger and older adults.

Separable neural signatures of confidence during perceptual decisions

The paper identifies distinct neural signatures for perceptual decision-making and confidence evaluation in humans using electroencephalography.

Priors and Payoffs in Confidence Judgments

This study investigates how priors and payoffs influence confidence judgments in perceptual tasks, finding that humans do not follow the normative model of confidence behavior.

Performance Monitoring for Sensorimotor Confidence: A Visuomotor Tracking Study

This study investigates how humans monitor their sensorimotor confidence during visuomotor tracking tasks and finds that recent errors have a greater influence on confidence judgments.

When temporal attention lacks confidence

This paper investigates how temporal attention affects confidence judgments in a perceptual task, finding that confidence is influenced by selection delays but not by early attentional biases.
