In the present study, we thus investigated how adults synchronize with emotional facial expressions. The participants had to synchronize their taps with a rhythmical sequence of faces and then continue tapping at the same rhythm without faces. Three inter-stimulus intervals (500, 700, and 900 ms) and six different facial expressions (disgust, neutrality, sadness, joy, anger, and fear) were tested. In the synchronization phase, no difference was observed between the different facial expressions, suggesting that the participants tap in synchrony with external rhythms in the presence of stimuli whatever their emotional characteristics. However, in the continuation phase, an emotion effect emerged, with the individual rhythms being faster for the facial expressions of fear and, to a lesser extent, anger than for the other facial expressions. The motor r...

However, some researchers have demonstrated accurate temporal knowledge in young children and have explained their poor judgements on classical piagetian tasks not by their inability to correctly judge time, but by age-related attentional difficulties. Recently, researchers have thus reassessed the temporal behaviour in children with the experimental paradigms used in animals and humans adults in the framework of the temporal information processing models that assume the existence of an internal clock. Findings suggest that this type of clock is functional at an early age. Other findings allow us to better understand the role of the development of attention, memory and metacognitive processes in the development of the abilities to judge time. The aim of this article is to synthesize these recent findings.

The study of parent-infant interaction with a premature infant is vast and complex. Numerous variables concerning the infant, the parents, their interactions, and the environmental conditions in the neonatal intensive care unit (NICU) influence the parent-preterm interactive “system.”

For decades, researchers have considered this primitive crawling behavior a spinal reflex, immune to supra spinal control. However recent research suggest that neonatal crawling is already responsive to visual and olfactory stimuli processed at a supra spinal level. Here we report that a few hours post birth, French newborns can also modulate their crawling in response to their native language - a source of information that is processed supra-spinally. The crawling patterns of 23 French-born newborns were recorded on video and via an infra-red motion capture system during two randomly ordered 2-minute trials. The newborns were secured on a mini skateboard to facilitate arm and leg movements during their crawling propulsion. They heard a repetitive sequence of the same sentences either in French, their native language, or in English, a rhythmically different and hence discriminable unfamiliar language, on each trial. In French, compared to English, crawling was enhanced, with significantly more arm and leg steps and significantly more and larger trunk rotations in the cephalo-caudal axis. Moreover, newborns rotated their head and trunk toward the appropriate loud speaker when hearing French but not English. These preliminary findings suggest that newborn crawling is not a simple stereotyped reflex under spinal control, but a complex pattern that can be modulated in response to higher-order, supra-spinally-processed stimuli. The findings open fascinating questions about the range of stimuli to which newborn crawling is responsive. This article is protected by copyright. All rights reserved.

Maternal breathing, heartbeats, walking, dancing, running, speaking, singing, etc., all bathe the fetus in an environment of varied rhythmic stimuli: vestibular, somatosensory, tactile, and auditory. In contrast, the NICU environment does not offer the same proportion of rhythmic stimulation. After analyzing the lack of rhythmic stimulation in the NICU, this review highlights the different proposals for vestibular and/or auditory rhythmic stimulation offered to preterm infants alone and with their parents. The focus is on the beneficial effects of auditory and vestibular stimulation involving both partners of the mother–infant dyad. A preliminary study on the influence of a skin-to-skin lullaby on the stability of maternal behavior and on the tonic emotional manifestations of the preterm infant is presented as an example. The review concludes with the im...

Etre synchronise avec son environnement est vital pour le developpement cognitif, emotionnel et sensori-moteur du jeune enfant. Le but de cette etude est d'explorer le traitement temporel des durees courtes au cours du developpement. Par une procedure adaptee aux jeunes enfants, nous avons analyse le tempo moteur spontane (TMS) et la synchronisation rythmique chez les nouveau-nes, les nourrissons et les tres jeunes enfants. Les resultats revelent que les enfants sont capables d'adapter leur reponse motrice a un tempo auditif. Cependant, le type de modification depend de l'âge et de la nature des informations temporelles presentes dans l'environnement (frequence du tempo, variation de frequence par rapport au tempo de base, etc.…). Les resultats sont interpretes en fonction des modeles developpementaux d'horloge interne. MOTS-CL...

The current study aimed to examine the nature of the coupling between olfactory stimuli from the mother and the newborn's crawling and rooting (exploratory movements of the head). To examine the coupling, the crawling and rooting behavior of 28 2-day-old newborns were studied while they were supported prone on a mobility device shaped like a mini skateboard, the Crawliskate, their head positioned directly on top of a pad infused with either their mother's breast odor (Maternal) or the odor of water (Control). Video and 3D kinematic analyses of the number and types of limb movements and quantification of displacement across the surface revealed that newborns are significantly more efficient crawlers when they smell the maternal odor, moving greater distances although performing fewer locomotor movements. In addition, the newborns made significantly more head rooting movements in the presence of the maternal odor. These findings suggest that the circuitry underlying quadrupedal locomotion and exploratory movements of the head is already adaptable to olfactory information via higher brain processing. Moreover, the coupling between olfaction and the two action systems, locomotion and rooting, is already differentiated. As crawling enables the newborn to move toward the mother's breast immediately after birth and facilitates mother-infant interaction, the results of this study highlight the potential value of using maternal odors to stimulate mobility in infants at risk of motor delay and/or deprived of this odor when born prematurely.

The complex nature and the multiplicity of time scales make the associated cognitive processes both interesting and difficult to understand. Early childhood is a particularly important time for the study of short durations (i.e. durations of less than one second). Rhythmic behavioral activities such as sucking, kicking and crawling are associated, from the moment of birth, with particular stages of neuromuscular maturation. This temporary behavior, involving non-coordinated movements, eventually changes to voluntary and coordinated motor behavior (Thelen 1979). Temporal contingency is also of prime importance in intermodal perception (Schmuckler, 1996; Lewkowicz, 2000, 2003). Therefore, the developmental pattern in the temporal processing of young children is an interesting question. Short duration processes are studied using an isochronous sequence of intervals. The frequency of these intervals is usually called the tempo 1. Results show that when the number of intervals in a sequence is increased a specific interval can be more precisely processed, and that this is related to the amount of information available (Drake & Botte, 1993). That is, the more intervals produced, the more precise is its memory trace and the greater the sensitivity. The accuracy of interval processing can be assessed by distinguishing one tempo from another (i.e. a discrimination task). Thus, tempo discrimination tasks and, more specifically, the discrimination threshold (i.e. the Tempo Discrimination in 3-and 4-year-old children: performances and threshold

Analyses of the number and types of limb movements and their characteristics, the coactivation of limb pairs, and the displacement across the surface, revealed that newborns can crawl with locomotor patterns similar to those documented during quadrupedal locomotion in animals and human adults. This was particularly apparent on the skateboard. This discovery suggests that locomotor circuitry underlying quadrupedal locomotion develops during fetal life. Drawing upon other evidence for a quadrupedal organization underlying bipedal gait, we argue that early quadrupedal training may enhance interventions designed to hasten the onset of independent walking.

Sixteen term infants, twelve low-risk near-term (LBW) preterm infants and eight Very Low Birth Weight (VLBW) preterm infants were tested at four months post term. Infants were habituated with an auditory–visual synchronic situation: a visual ball bounced back in synchrony with an auditory sound. In the test phase, an asynchronized situation and a synchronized situation were presented alternately three times. The results showed that VLBW infants spent more time looking at the target before being habituated compared to LBW preterm infants and full-term infants. Specific areas of interest showed that VLBW infants spent less time on the target than LBW and full-term infants and had a more heterogeneous visual exploration. Nevertheles...

Cette synchronisation lui permet de communiquer et d’interagir avec son environnement. Cette capacite precoce de synchronisation est consideree comme un des fondements des interactions sociales et serait specifique aux especes animales capables d’utiliser les apprentissages vocaux pour communiquer. Pour etre capable de synchronisation, l’enfant doit non seulement percevoir les stimulations rythmiques de son environnement, mais aussi produire ses propres activites motrices rythmiques et les synchroniser a ces stimulations externes. Il doit pour cela anticiper l’arrivee de la stimulation rythmique pour repondre au bon moment. La synchronisation de l’enfant a son environnement, si importante qu’elle soit pour lui, n’en demeure pas moins une activite complexe qui requiert des capacites de perception et de production temporelle, d’anticipation et d’ajustement de la reponse au stimulus externe. Cette revue de question met l’accent sur les capacites du fœtus et du nouveau-ne a percevoir, a produire et a se synchroniser a des rythmes exterieurs. Les synchronisations sensori-motrices semblent jouer un role crucial dans les interactions sociales.
