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...

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...

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...

Abstract The success of human cooperation crucially depends on mechanisms enabling individuals to detect unreliability in their conspecifics. Yet, how such epistemic vigilance is achieved from naturalistic sensory inputs remains unclear. Here we show that listeners’ perceptions the certainty and honesty other speakers speech are based a common prosodic signature. Using data-driven method, separately decode features driving speaker’s across pitch, duration loudness. We find these two kinds...

Current approaches to analysing EEG hyperscanning data in the developmental literature typically consider interpersonal entrainment between interacting physiological systems as a time-invariant property. This approach obscures crucial information about how is established and maintained over time. Here, we describe methods, present computational algorithms, that will allow researchers address this gap literature. We focus on two different measuring entrainment, namely concurrent (e.g., power...

Temporal coordination during infant-caregiver social interaction is thought to be crucial for supporting early language acquisition and cognitive development. Despite a growing prevalence of theories suggesting that increased inter-brain synchrony associates with many key aspects interactions such as mutual gaze, little known about how this arises Here, we investigated the role gaze onsets potential driver synchrony. We extracted dual EEG activity around naturally occurring in N = 55 dyads...

We know that infants' ability to coordinate attention with others toward the end of first year is fundamental language acquisition and social cognition. Yet, we understand little about neural cognitive mechanisms driving infant in shared interaction: do infants play a proactive role creating episodes joint attention? Recording electroencephalography (EEG) from 12-mo-old while they engaged table-top their caregiver, examined communicative behaviors activity preceding following infant- vs....

It has been argued that a necessary condition for the emergence of speech in humans is ability to vocalise irrespective underlying affective states, but when and how this happens during development remains unclear. To examine this, we used wearable microphones autonomic sensors collect multimodal naturalistic datasets from 12-month-olds their caregivers. We observed that, across day, clusters vocalisations occur elevated infant caregiver arousal. This relationship stronger infants than...

There has been little investigation of the way source monitoring, ability to track one’s knowledge, may be involved in lexical acquisition. In two experiments, we tested whether toddlers (mean age 30 months) can monitor their knowledge and reevaluate implicit belief about a word mapping when this is proven unreliable. Experiment 1 replicated previous research (Koenig & Woodward, 2010 ): children displayed better performance learning test they learned words from speaker who previously...

Abstract Human interactions are often improvised rather than scripted, which suggests that efficient coordination can emerge even when collective plans largely underspecified. One possibility is such forms of primarily rely on mutual influences between interactive partners, and perception–action couplings as entrainment or mimicry. Yet some joint actions appear difficult to explain solely by appealing these emergent mechanisms. Here, we focus free improvisation, a form highly unplanned...

Over the past few years, field of visual social cognition and face processing has been dramatically impacted by a series data-driven studies employing computer-graphics tools to synthesize arbitrary meaningful facial expressions. In auditory modality, reverse correlation is traditionally used characterize sensory at level spectral or spectro-temporal stimulus properties, but not higher-level cognitive e.g. words, sentences music, lack able manipulate dimensions that are relevant for these...

Content produced for young audiences is structured to present opportunities learning and social interactions. This research examines multi-scale temporal changes in predictability Child-directed songs. We developed a technique based on Kolmogorov complexity quantify the rate of change textual information content over time. method was applied corpus 922 English, Spanish, French publicly available child adult-directed texts. song lyrics (CDSongs) showed overall lower compared Adult-directed...

A wealth of theoretical and empirical arguments have suggested that music triggers emotional responses by resembling the inflections expressive vocalizations, but done so using low-level acoustic parameters (pitch, loudness, speed) that, in fact, may not be processed listener reference to human voice. Here, we take opportunity recent availability computational models allow simulation three specifically vocal behaviours: smiling, tremor roughness. When applied musical material, find these...

While coordination in joint-music making is often associated with synchronized and converging behaviors, research on group creativity routinely emphasizes the importance of dissensus individual autonomy collective creative endeavors.When musicians perform together, there might thus be a tension between demands that creativity, which could lead them to inject some degree their interactions foster musical output.In this paper, we investigate two listening experiments possibility dissensual...

Abstract A widespread belief is that large groups engaged in joint actions require a high level of flexibility are unable to coordinate without the introduction additional resources such as shared plans or hierarchical organizations. Here, we put this test, by empirically investigating coordination within group 16 musicians performing collective free improvisation—a genre which improvisers aim at creating music complex and unprecedented possible relying on an external conductor. We show...

Almost all early cognitive development takes place in social contexts. At the moment, however, we know little about neural and mechanisms that drive infant attention during interactions. Recording EEG naturalistic caregiver-infant interactions (N=66), compare two different accounts. Attentional scaffolding perspectives emphasise role of caregiver structuring child’s behaviour, whilst active learning models focus on motivational factors, endogenous to infant, guide their attention. Our...
