Consciousness Arrives Neurophysiological measures in human adults correspond to the transition between very brief, “unnoticeable,” and slightly longer-lived visual stimuli that penetrate deeply enough leave a conscious imprint subjects report they can “see.” Kouider et al. (p. 376 ) have performed parallel behavioral neurophysiological studies infants identify similar neural signal appears mark development of consciousness.
Significance Although many animals have been shown to monitor their own uncertainty, only humans seem the ability explicitly communicate uncertainty others. It remains unknown whether this is present early in development, or it emerges later alongside language development. Here, using a nonverbal memory-monitoring paradigm, we show that infants are able strategically ask for help avoid making mistakes. These findings reveal capable of monitoring and communicating uncertainty. We propose...
Several studies have investigated the neural correlates of conscious perception by contrasting functional magnetic resonance imaging (fMRI) activation to and nonconscious visual stimuli. The results often reveal an amplification posterior occipito-temporal its extension into a parieto-frontal network. However, some these effects might be due greater deployment attentional or strategical processes in condition. Here, we examined brain activity evoked visible invisible stimuli, both which were...
We argue that the lack of consensus regarding existence subliminal semantic processing arises from not taking into account fact linguistic stimuli are represented across several levels (features, letters, word form) can independently reach or awareness. Using masked words, we constructed conditions in which participants were aware some letters fragments a word, while remaining unaware whole word. Three experiments using Stroop priming paradigm show when stimulus set is reduced and encouraged...
Sleep is characterized by a loss of behavioral responsiveness. However, recent research has shown that the sleeping brain not completely disconnected from its environment. How neural activity constrains ability to process sensory information while asleep yet unclear. Here, we instructed human volunteers classify words with lateralized hand responses falling asleep. Using an electroencephalographic (EEG) marker motor preparation, show how responsiveness modulated across sleep. These...
Abstract Sleep and memory are deeply related, but the nature of neuroplastic processes induced by sleep remains unclear. Here, we report that traces can be both formed or suppressed during sleep, depending on phase. We played samples acoustic noise to sleeping human listeners. Repeated exposure a novel Rapid Eye Movements (REM) light non-REM (NREM) leads improvements in behavioral performance upon awakening. Strikingly, same deep NREM impaired Electroencephalographic markers learning...
Humans adapt their behavior not only by observing the consequences of actions but also internally monitoring performance. This capacity, termed metacognitive sensitivity [1, 2], has traditionally been denied to young children because they have poor capacities in verbally reporting own mental states [3-5]. Yet, these observations might reflect children's limited for explicit self-reports, rather than limitations metacognition per se. Indeed, shown simple computational mechanisms 6-8], and can...
Falling asleep leads to a loss of sensory awareness and the inability interact with environment [1Ogilvie R.D. The process falling asleep.Sleep Med. Rev. 2001; 5: 247-270Abstract Full Text PDF PubMed Scopus (212) Google Scholar]. While this was traditionally thought as consequence brain shutting down external inputs, it is now acknowledged that incoming stimuli can still be processed, at least some extent, during sleep [2Hennevin E. Huetz C. Edeline J.M. Neural representations sleep: from...
Prior expectations shape neural responses in sensory regions of the brain, consistent with a Bayesian predictive coding account perception. Yet, it remains unclear whether such mechanism is already functional during early stages development. To address this issue, we study how infant brain responds to prediction violations using cross-modal cueing paradigm. We record electroencephalographic expected and unexpected visual events preceded by auditory cues 12-month-old infants. find an...
It is often assumed that neural activity in face-responsive regions of primate cortex correlates with conscious perception faces. However, whether such occurs without awareness still debated. Using functional magnetic resonance imaging (fMRI) conjunction a novel masked face priming paradigm, we observed modulations could not be attributed to perceptual awareness. More specifically, found reduced several classic face-processing regions, including the "fusiform area," "occipital and superior...
In the study of nonconscious processing, different methods have been used in order to render stimuli invisible. While their properties are well described, level at which they disrupt processing remains unclear. Yet, such accurate estimation depth processes is crucial for a clear differentiation between conscious and cognition. Here, we compared facial expressions rendered invisible through gaze-contingent crowding (GCC), masking, continuous flash suppression (CFS), three techniques relying...
Metacognition is the ability to monitor and control cognition. Because young children often provide inaccurate metacognitive judgments when prompted do so verbally, it has long been assumed that this does not develop until late childhood. This claim now challenged by new studies using nonverbal paradigms revealing basic forms of metacognition—such as estimate decision confidence or errors—are present even in preverbal infants. line evidence suggests adapt their environment only considering...
The role of the basal ganglia, and more specifically striatum, in language is still debated. Recent studies have proposed that linguistic abilities involve two distinct types processes: retrieving stored information, implicating temporal lobe areas, application combinatorial rules, fronto-striatal circuits. Studies patients with focal lesions neurodegenerative diseases suggested a for striatum morphological rule application, but functional imaging found left caudate was involved syntactic...
We explored the impact of task context on subliminal neural priming using functional magnetic resonance imaging. The repetition words during semantic categorization produced activation reduction in left middle temporal gyrus previously associated with semantic-level representation and dorsal premotor cortex. By contrast, reading aloud enhancement inferior parietal lobe print-to-sound conversion ventral Analyses effective connectivity revealed that set for generated reciprocal excitatory...
Using a sandwich-masked priming paradigm with faces, we report two ERP effects that appear to reflect different levels of subliminal face processing. These repetition dissociate in their onset, scalp topography, and sensitivity familiarity. The "early" effect occurred between 100 150 ms, was maximally negative-going over lateral temporoparietal channels, found for both familiar unfamiliar faces. "late" 300 500 positive-going centroparietal only early resembled our previous fMRI data from the...
