Visual Confidence by Mamassian, Pascal

“…Visual confidence refers to an observer's ability to judge the accuracy of her perceptual decisions. Even though confidence judgments have been recorded since…”

Confidence controls perceptual evidence accumulation by Balsdon, Tarryn, Wyart, Valentin, Mamassian, Pascal

“…Perceptual decisions are accompanied by feelings of confidence that reflect the likelihood that the decision was correct. Here we aim to clarify the…”

Uncertain perceptual confidence by Mamassian, Pascal

“…To interact safely with our environment, we must be able to judge our confidence in what we perceive. But what cues do we use to compute perceptual confidence?…”

Age-related differences in visual confidence are driven by individual differences in cognitive control capacities by Klever, Lena, Mamassian, Pascal, Billino, Jutta

“…Visual perception is not only shaped by sensitivity but also by confidence, i.e., the ability to estimate the accuracy of a visual decision. Younger observers…”

Overconfidence in an Objective Anticipatory Motor Task by Mamassian, Pascal

“…Overconfidence can place humans in hazardous situations, and yet it has been observed in a variety of cognitive tasks in which participants have to rate their…”

Weighting mean and variability during confidence judgments by de Gardelle, Vincent, Mamassian, Pascal

“…Humans can not only perform some visual tasks with great precision, they can also judge how good they are in these tasks. However, it remains unclear how…”

Separable neural signatures of confidence during perceptual decisions by Balsdon, Tarryn, Mamassian, Pascal, Wyart, Valentin

“…Perceptual confidence is an evaluation of the validity of perceptual decisions. While there is behavioural evidence that confidence evaluation differs from…”

Confidence as a Common Currency between Vision and Audition by de Gardelle, Vincent, Le Corre, François, Mamassian, Pascal

“…The idea of a common currency underlying our choice behaviour has played an important role in sciences of behaviour, from neurobiology to psychology and…”

Persistent states in vision break universality and time invariance by Wexler, Mark, Duyck, Marianne, Mamassian, Pascal

“…Studies of perception usually emphasize processes that are largely universal across observers and—except for short-term fluctuations—stationary over time. Here…”

Measuring uncertainty in human visual segmentation by Vacher, Jonathan, Launay, Claire, Mamassian, Pascal, Coen-Cagli, Ruben

“…Segmenting visual stimuli into distinct groups of features and visual objects is central to visual function. Classical psychophysical methods have helped…”

Suprathreshold perceptual decisions constrain models of confidence by Locke, Shannon M, Landy, Michael S, Mamassian, Pascal

“…Perceptual confidence is an important internal signal about the certainty of our decisions and there is a substantial debate on how it is computed. We…”

Object perception as bayesian inference by KERSTEN, Daniel, MAMASSIAN, Pascal, YUILLE, Alan

“…We perceive the shapes and material properties of objects quickly and reliably despite the complexity and objective ambiguities of natural images. Typical…”

Confidence judgments are associated with face identification accuracy: Findings from a confidence forced-choice task by Jeckeln, Géraldine, Mamassian, Pascal, O’Toole, Alice J.

“…Confidence is assumed to be an indicator of identification accuracy in legal practices (e.g., forensic face examination). However, it is not clear whether…”

Evaluation of objective uncertainty in the visual system by Barthelmé, Simon, Mamassian, Pascal

“…The role of sensory systems is to provide an organism with information about its environment. Because sensory information is noisy and insufficient to uniquely…”

A Glossy Simultaneous Contrast: Conjoint Measurements of Gloss and Lightness by Hansmann-Roth, Sabrina, Mamassian, Pascal

“…Interactions between the albedo and the gloss on a surface are commonplace. Darker surfaces are perceived glossier (contrast gloss) than lighter surfaces and…”

Flexible mechanisms underlie the evaluation of visual confidence by Barthelmé, Simon, Mamassian, Pascal, Mumford, David

“…Visual processing is fraught with uncertainty: The visual system must attempt to estimate physical properties despite missing information and noisy mechanisms…”

Bayesian decision theory as a model of human visual perception: testing Bayesian transfer by Maloney, Laurence T, Mamassian, Pascal

“…Bayesian decision theory (BDT) is a mathematical framework that allows the experimenter to model ideal performance in a wide variety of visuomotor tasks. The…”

When an Event Is Perceived Depends on Where We Attend by Jovanovic, Ljubica, Mamassian, Pascal

“…Does the moment when an event is perceived depends on where it is presented? To measure when participants perceived events, they were first familiarized with…”

A Normalization Mechanism for Estimating Visual Motion across Speeds and Scales by Gekas, Nikos, Meso, Andrew I., Masson, Guillaume S., Mamassian, Pascal

“…Interacting with the natural environment leads to complex stimulations of our senses. Here we focus on the estimation of visual speed, a critical source of…”

Prior knowledge of illumination for 3D perception in the human brain by Gerardin, Peggy, Kourtzi, Zoe, Mamassian, Pascal

“…In perceiving 3D shape from ambiguous shading patterns, humans use the prior knowledge that the light is located above their head and slightly to the left…”
