On the inseparability of the prior and neural resources in behavioural bias

The paper shows that prior expectations and neural resources can be integrated in sensory decision making, challenging the assumption of their separability.

Low-level features predict perceived similarity for naturalistic images

The paper shows that low-level image features predict perceived similarity between naturalistic scene regions, supporting the role of basic visual features in scene organization.

Investigating orientation adaptation following naturalistic film viewing

This study investigates orientation adaptation during naturalistic film viewing and finds stronger adaptation to cardinal orientations but weaker overall effects compared to standard tilt-aftereffect paradigms.

Reply to: Model mimicry limits conclusions about neural tuning and can mistakenly imply unlikely priors

The paper addresses criticisms of a previous study on visual cortex orientation representation and provides additional MEG data supporting the original findings.

Do Memories of Inferred Visual Representations Guide Low-level Perception?

This study investigates whether memories of complex objects influence perception by refining visual details, finding that while object memories enhance disambiguation, they do not improve visual sensitivity.

Priors for natural image statistics inform confidence in perceptual decisions

This study shows that confidence in perceptual decisions is influenced by natural image statistics, using a novel psychophysical paradigm.

Effects of oscillation phase on discrimination performance in a visual tilt illusion

The paper investigates how oscillation phase affects orientation perception in a visual tilt illusion, finding robust fluctuations in perception across different phases of alpha and theta oscillations.

A computational account of real-world attentional allocation based on visual gain fields

This study shows that visual attention operates in real-world coordinates, with high precision and minimal disruption during eye movements.

Neural tuning instantiates prior expectations in the human visual system

The paper shows that human visual system tuning reflects stimulus-specific variations not predicted by prior coding schemes, embedding environmental priors in sensory measurements.

Modality Independent or Modality Specific? Common Computations Underlie Confidence Judgements in Visual and Auditory Decisions

The paper investigates whether confidence judgments in visual and auditory decisions share common computational processes, finding that scaled evidence strength models best explain the data across modalities.

Contextual influences of visual perceptual inferences

The paper investigates how perceptual inferences balance long-term scene priors and immediate contextual information using naturalistic stimuli and a perceptual inference task.

Luminance and contrast of images in the THINGS database

The paper analyzes luminance and contrast in the THINGS database, finding that these properties can classify image concepts above chance and may confound cognitive neuroscience studies.

Spatial structure, phase, and the contrast of natural images

The paper tests the hypothesis that target detection in natural images is inversely related to spatial similarity with the background, finding that high similarity increases detectability due to phase alignment.

Border-ownership-dependent tilt aftereffect for shape defined by binocular disparity and motion parallax

The paper measures border-ownership-dependent tilt aftereffects in humans adapting to figures defined by motion parallax or binocular disparity, showing depth order selectivity and cue transferability.

Voluntary control of illusory contour formation

This study investigates how attentional goals influence the perception of illusory contours, showing that voluntary attention can determine perceptual organization of fragmented visual scenes.

Selective attention modulates surface filling-in

This study investigates whether voluntary attention modulates perceptual lightness filling-in using a modified Kanizsa illusory triangle.

Visual working memory is independent of the cortical spacing between memoranda

The paper investigates whether visual working memory is affected by cortical spacing between memoranda and finds no such effect, suggesting memory and perception use different neural mechanisms.

Visual crowding is a combination of an increase of positional uncertainty, source confusion, and featural averaging

This study investigates visual crowding by analyzing positional uncertainty, source confusion, and featural averaging through a hybrid adjustment method and modeling.
