Consensus Goals in the Field of Visual Metacognition
Despite the tangible progress in psychological and cognitive sciences over the last several years, these disciplines still trail other more mature sciences in identifying the most important questions that need to be solved. Reaching such consensus could lead to greater synergy across different laboratories, faster progress, and increased focus on solving important problems rather than pursuing isolated, niche efforts. Here, 26 researchers from th…
Metacognition tracks sensitivity following involuntary shifts of visual attention
Salient, exogenous cues have been shown to induce a temporary boost of perceptual sensitivity in their immediate vicinity. In two experiments involving uninformative exogenous cues presented at various times before a target stimulus, we investigated whether human observers (N = 100) were able to monitor the involuntary increase in performance induced by such transients. We found that an increase of perceptual sensitivity (in a choice task) and en…
Uncertain perceptual confidence
Metacognitive blindness in temporal selection during the deployment of spatial attention
How does orienting attention in space affect the quality of our confidence judgments? Orienting attention to a particular location is known to boost visual performance, but the deployment of attention is far from being instantaneous. Whether observers are able to monitor the time needed for attention to deploy remains largely unknown. To address this question, we adapted a "Wundt clocks" paradigm, asking observers (N=140) to reproduce the phase o…

Modeling perceptual confidence and the confidence forced-choice paradigm
Perceptual confidence is an evaluation of the validity of our perceptual decisions. We present here a complete generative model that describes how confidence judgments result from some confidence evidence. The model that generates confidence evidence has two main parameters, confidence noise and confidence boost. Confidence noise reduces the sensitivity to the confidence evidence, and confidence boost accounts for information used for confidence …
Global visual confidence
Visual confidence is the observers' estimate of their precision in one single perceptual decision. Ultimately, however, observers often need to judge their confidence over a task in general rather than merely on one single decision. Here, we measured the global confidence acquired across multiple perceptual decisions. Participants performed a dual task on two series of oriented stimuli. The perceptual task was an orientation-discrimination judgme…

Does Confidence Use a Common Currency Across Two Visual Tasks
Diagnosis of Hyperactivity Disorder in Gifted Children Depends on Observational Sources
Attention Deficit/Hyperactivity Disorder (AD/HD) is often reported in gifted children. Several authors, however, suggest that gifted children, in fact display AD/HD-like behaviors, especially at school due to boredom resulting from academically understimulating environments. In order to clarify this issue, a study was conducted on 37 gifted children based on four different observational assessments of hyperactivity disorder (father, mother, teach…
Métamères perceptifs et perception bistable
Les métamères perceptifs et la perception bistable sont deux phénomènes clés de la perception consciente. Dans le premier cas, deux stimuli physiquement distincts sont perçus de la même manière, alors que dans le second cas, le même stimulus est perçu de deux manières distinctes. Que peuvent apporter les approches externalistes et internalistes pour expliquer ces phénomènes
