On a confusion about there being two types of consciousness

Progress in the scientific study of consciousness has been impeded by several fundamental controversies. One pertains to a major divide between theories: sensory versus cognitive. Here, we argue that the key to resolving this controversy is to …

Exogenous and endogenous sources of uncertainty inform global performance monitoring

We have a fair understanding of what contributes to our confidence when performing individual trials of a task. However, little is known regarding the factors driving more global metacognitive estimates when a task is repeated. The present study …

Neural correlates of perceptual consciousness from within: a narrative review of human intracranial research

Despite many years of research, the quest to identify neural correlates of perceptual consciousness (NCC) remains unresolved. One major obstacle lies in methodological limitations: most studies rely on non-invasive neural measures with limited …

Cortical evidence accumulation for visual perception occurs irrespective of reports

Perception is a multi-faceted, dynamical process that can be tackled empirically through measures of stimulus detectability and confidence. We recorded stereo-electroencephalographic data of 29 participants partaking in three pre-registered …

Evidence accumulation in the pre-supplementary motor area and insula drives confidence and changes of mind

Evidence accumulation is a powerful mechanism to explain the temporal dynamics of decisions, as well as their metacognitive components such as confidence judgments and changes of mind. However, it is still unclear how and where in the brain evidence …

Characterizing early auditory deficits in schizophrenia using drift-diffusion modeling

Introduction: While tone-matching disturbances have been extensively documented in schizophrenia, it remains unclear if impaired tone-matching performance is solely related to early sensory dysfunction or if the ability to appropriately translate …

Flowers for Algernon: How metacognition affects quality of life in schizophrenia. Structural equation modeling with the Face-Sz cohort

Background and HypothesisWe examined the association between metacognitive performance, functioning, and quality of life (QoL) in schizophrenia using structural equation model analyses.Study DesignA sample of 249 participants was assessed for …

Studying unconscious processing: Contention and consensus

The scope of unconscious processing has long been, and still remains, a hotly debated issue. This is driven in part by the current diversity of methods to manipulate and measure perceptual consciousness. Here, we provide ten recommendations and nine …

Object relations are processed with, but not without, awareness

The scope of unconscious integration is widely debated. Here, we examined this question, focusing specifically on deciphering the relations between two associatively related objects, in a set of five behavioral and electrophysiological experiments. …

Individual differences do not mask effects of unconscious processing

A wave of criticisms and replication failures is currently challenging claims about the scope of unconscious perception and cognition. Such failures to find unconscious processing effects at the population level may reflect the absence of …
