• [hal-04484251] Spontaneous tempo production in cockatiels (Nymphicus hollandicus) and jungle crows (Corvus macrorhyncos)

  29 février 2024

  Musical and rhythmical abilities are poorly documented in non-human animals. Most of the existing studies focused on synchronisation performances to external rhythms. In humans, studies demonstrated that rhythmical processing (e. g. rhythm discrimination or synchronisation to external rhythm) is dependent of an individual measure: the individual tempo. It is assessed by asking participants to produce an endogenous isochronous rhythm (known as spontaneous motor tempo) without any specific instructions nor temporal cue. In non-human animal literature, studies describing spontaneous and endogenous production of motor tempo without any temporal clue are rare. This exploratory study aims to describe and compare the spontaneous motor tempo of cockatiels and jungle crows. Data were collected on spontaneous beak drumming behaviours of birds housed in laboratory. Inter beak strokes intervals were calculated from sound tracks of videos. The analyses revealed that inter beak strokes intervals are non-randomly distributed intervals and are isochronous. Recorded spontaneous motor tempos are significantly different among some cockatiels. Since we could only conduct statistical analysis with one corvid, we cannot conclude about this species. Our results suggest that cockatiels and jungle crows have individual tempos, thus encouraging further investigations.
• [hal-03970690] Performing spontaneous motor tempo improves children's attentional performance

  2 février 2023

  Most children move rhythmically when they are focused on a task, whereas they are expected to remain still. Yet, Dynamic Attention Theory provides a theoretical framework to support the hypothesis that producing a spontaneous motor tempo can improve attentional performance. We therefore developed an experimental procedure designed to test this effect in the ecological context of classroom work: 64 8-year-old children participated in a 3-session, whole-class experiment. Each session began with a preliminary movement phase (spontaneous tempo with the hand or with the head or without movement). Then, in a second phase, the children completed one of three versions of the d2 attentional test. Our results showed that only the spontaneous tempo with hand condition significantly improved attentional performance. This protocol shows that it is possible to adapt teaching practices to allow children to mobilize their attention through these movements without disrupting classroom functioning.

• [hal-02952596] Le tempo, fondement des compétences musicales et support du développement sociocognitif

  5 octobre 2020

  La musique est un objet sonore complexe mais qui repose sur une organisation temporelle très régulière. Cette caractéristique forte permet, lorsqu’elle est maîtrisée, d’anticiper les événements et de s’y synchroniser. La littérature scientifique souligne que l’être humain a une capacité à traiter ces régularités sur la base d’un tempo interne qui caractérise chaque individu. Bon nombre d’études chez l’adulte, l’enfant et le bébé montrent que le tempo interne oriente efficacement l’attention vers les objets ou événements importants. Au cours des premières années, pendant lesquelles cette compétence temporelle se développe, le jeune enfant baigne déjà dans un milieu riche en régularités temporelles multimodales, en produit de nombreuses et est soutenu dans son développement par ses partenaires sociaux privilégiés. Ces derniers lui proposent des interactions aux régularités temporelles saillantes qui lui permettent d’orienter son attention pour développer ses compétences cognitives et sociales.
• [hal-01643578] Soutenir l’élaboration de la relation parent-enfant en cas de prématurité

  22 novembre 2017

  L’évolution de la prise en charge de la prématurité met à jour un écueil particulier, celui d’un développement de la parentalité et de la relation parents-bébé entravé par une naissance trop précoce z Les conséquences à court et à long termes des perturbations de ces deux dimensions en font des enjeux majeurs dans la prise en charge institutionnelle des parents et de leur enfant prématuré.
• [hal-01586927] Update on Mental Health of Infants and Children of Parents Affected With Mental Health Issues

  13 septembre 2017

  This paper highlights the most recent publications, in the field of psychiatry, on offspring of patients with psychiatric illnesses such as schizophrenia and bipolar disorder, and then summarizes what we know about the progeny of adults with mood disorders, the most prevalent of parental disorders. Studies examining personality disorders and contextual factors such as stress and trauma are examined with a focus on the crucial question of development and attachment status in children. Findings converge to reveal that offspring of parents (generally mothers) with most major psychiatric disorders present a higher risk for all mental disorders, and a wide range of disorders are also found in children, adolescent, and finally adult offspring of mothers with mood and anxiety disorders. Developmental psychopathology and infant and child psychiatry have focused on early relationship formation through social interaction and attachment patterns as pathways affected by vulnerability or resilience factors. First year of life longitudinal studies following mothers and infants has shown that maternal psychopathology is positively correlated with higher risk of attachment issues. It would seem that pathology appears when adaptation to real-life contexts becomes difficult in association with an accumulation of negative individual characteristics and environmental circumstances. We suggest that in order to move forward psychiatry should embrace a developmental cascade model, which posits a cumulative pathway for the emergence of psychopathology in the developing child. We propose that we have sufficient knowledge today to start implementing multilevel approaches to enhance the health and mental health of the next generation.
• [hal-01645039] La liaison en « Périnatalogie » : des soins entre réseau, liaison et prise en charge mobile

  22 novembre 2017

  La période périnatale amène les (futures) mères à rencontrer régulièrement des professionnels de la santé et constitue de ce fait un moment privilégié pour identifier les signes de vulnérabilité et pour initier des mesures préventives et/ou thérapeutiques pour ces patientes qui sont dans une phase de sensibilité psychique plus importante. La présente étude a pour premier objectif de déterminer si l’unité de psychiatrie d’urgence en maternité PPUMMA a répondu aux besoins qui ont conduits à sa création en s’appuyant sur la description de 8 années d’activité. Un second objectif est d’analyser les diagnostics posés sur la totalité de la période puis de les mettre en perspective dans leur évolution entre les premières années de fonctionnement et les plus récentes. Méthodes. – À partir de ce constat et en lien avec les professionnels de la périnatalité, une équipe de liaison en psychiatrie périnatale (PPUMMA) a été créée pour répondre aux besoins spécifiques à cette période. L’analyse des données a été effectuée sur l’activité de l’unité entre 2008 et 2015, soit 1817 nouvelles patientes. Résultats. – Une majorité des demandes est faite au cours de la période anténatale et est suivie d’une prise en charge rapide, conformément à l’objectif de prévention du dispositif, et grâce notamment au travail en réseau. On observe une sur-représentation des patientes de moins de 20 ans et des plus de 40 ans. Les diagnostics posés suite à la prise en charge révèlent une forte proportion de troubles de la personnalité et du comportement chez l’adulte. Conclusions. – L’ensemble des données souligne l’importance de la détection et de la prise en charge précoce à cette période de la vie. La psychiatrie de liaison dans ce cadre favorise le repérage efficace de troubles maternels sévères et à plus long terme permettent la prévention des risques psychiatriques pour l’enfant.

• [hal-04246761] Langage adressé au bébé et exploration visuelle chez le bébé de 4,5mois : mise en évidence d’un effet de genre

  17 octobre 2023

  Background & aim. – Infant directed speech (IDS) is a simplified form of language known to capture infant visual attention. IDS is an early form of communication to which infants are particularly sensitive beginning at birth and play an essential part in the acquisition of language and in the development of social cognition. The present research aims at determining whether an infant as young as 4.5 months explores different face zones of a person talking to her when the form of speech employed is either IDS or adult directed speech (ADS). We wish to bring more insight in the relation between the way an adult talks to an infant and the infant’s visual attention, such a relation being a central tenet to understanding early interactions. Methods. – Eighteen 4.5 month-old infants were presented videos of a woman talking either IDS or ADS, each video played with and without soundtrack. The total time focused respectively on eye areas and mouth area was collected with an eye-tracking system (Tobii 2150). Results and conclusion. – Results showed evidence of more visual exploration when the soundtrack was played as opposed to silence while exploration focused more on the eye area. Moreover, interaction effects were observed involving a gender effect. These results raise the question of the importance of infant’s gaze and attention directed to the face, and specifically to the eyes of the partner. Indeed, eyes of a talking face seem of great importance at 4.5 months of age, i.e., long before an infant is known to be able to interpret a referential gaze. Our results also add to the gender effect differences found in early interactions between infant and social partners. A better understanding of what infant attention focuses on in a communication-oriented situation, including infant gender impact, would not only help to detect early parent-infant communication distortions but add to a more adapted and efficient clinical follow-up.
• [hal-04133300] Young children’s difficulties in switching from rhythm production to temporal interval production (>1 s)

  19 juin 2023

  This study examined the young children's abilities to switch from rhythm production, with short inter-tap intervals (ITIs), to temporal interval production, with long ITI (>1 s), in a sensorimotor synchronization task. Children aged 3-and 5-year-olds were given six sessions of synchronization. In a control group, they had to synchronize their ITI to an inter-stimulus interval (ISI) of 4 s. In the experimental group, they must progressively increase their ITI for one session to the next (from 0.4 to 4.0-s ISI). Our results showed that the 5-yearolds produced longer ITI that the 3-year-olds in synchronization. However, the value of ITI in the 5-year-olds never exceeded 1.5 s, with more variable ITI in the control than in the experimental group. In addition, at 5 years, boys had more difficulties than girls in changing their tapping rhythm. These results suggest a temporal window in sensorimotor synchronization, beyond which the rhythm is lost and the synchronization becomes difficult.
• [hal-04687928] Young children's difficulties in switching from rhythm production to temporal interval production (>1 s)

  4 septembre 2024

  In order to efficiently perform audio-motor coordination children must process event duration. It has recently been shown that duration processing in adults involves two distinct, or at least hierarchically interrelated, processes. The processing of durations ranging from a hundred milliseconds to around one second is well accounted for by the Scalar Timing Theory. For duration above one second, temporal processing in adults appears to be task-dependent. Performances in the range of a hundred millisecond durations are usually studied with auditory tempo tasks. In this study, we examine timing performance in children for a large range of durations, from 400 ms to 4 seconds, using the same experimental design. The procedure consists in a motor synchronization task. Overall, our results show that 5 year olds perform better than 3 year olds. However, durations greater than, 1500 ms are difficult to process, leading to increasing variability in produced intervals. Moreover, only a few children are able to produce very long duration intervals. The main finding of this study confirms the existence of a break in the region of 1500 ms when a repeated synchronization task is tested. Consistently with the adult literature, this finding suggests the existence of two duration-dependent timing processes when children have to coordinate their motor behavior to external events

  1 mars 2017

  This study presents an ecological experiment investigating 6-month-olds' social engagement. Results show that infants look and smile more at a socially attending distant partner than at an inattentive partner and that their looking and smiling behavior is different when the inattentive partner is their mother.
• [hal-02887838] Régulation rythmique avant 4 ans : effet d'un tempo auditif sur le tempo moteur

  2 juillet 2020

  L'objectif de cette étude est d'analyser les capacités de l'enfant âgé de 1 ½ à 3 ½ ans à modifier son tempo moteur spontané (TMS) en fonction de tempi auditifs. Les résultats montrent que le TMS reste constant entre 1 ½ et 3 ½ ans et que, parallèlement, il devient plus régulier. Les enfants les plus âgés modifient leurs rythmes de frappes si le tempo auditif diffère d'au moins 20 % de leurs propres rythmes. La capacité des enfants à ralentir leurs rythmes de frappes se met en place plus tardivement que leur accéléra-tion. Enfin, les modifications du rythme de frappes induisent une modification équivalente du TMS mais transitoire.

• [hal-01645042] Tempo Discrimination in 3- and 4-year-old children: performances and threshold

  22 novembre 2017

  Durations of less than one second are involved in all kinds of activities, such as music perception or rhythmical production tasks. It is therefore important to know how short durations are processed at a young age. This study aims to define discrimination performance between 3- and 4-year-olds (tempo discrimination). The first 4 years of life are essential for cognitive development and there is little data concerning those years due to the extreme difficulty of finding methods to assess children’s timing performances. Moreover, the results yielded by previous experiments are controversial. Our data revealed that discrimination performances improve significantly within only a few months. The discrimination data from 3 and 4 year-olds are compared to those from older children. The overall results are discussed in a developmental model context.

• [hal-01645069] Modifications of Retinal Afferent Activity Induce Changes in Astroglial Plasticity in the Hamster Circadian Clock

  27 novembre 2017

  The circadian clock, located in the suprachiasmatic nucleus (SCN) of the hypothalamus in mammals, exhibits astroglial plasticity indicated by GFAP expression over the 24-h period. In this study, we evaluated the role of neuronal retinal input in the observed changes. Modifications of retinal input, either by rearing animals under darkness (DD) or under constant light (LL), or by suppressing afferent input (bilateral enucleation), induced drastic changes in astroglial plasticity. In enucleated animals, a dramatic decrease in GFAP expression was evident in the area of the SCN deprived of retinal projections, whereas persistence of a rhythmic variation was in those areas still exhibiting GFAP expression. By contrast, no changes in astrocytic plasticity were detected in hamsters maintained under LL. These data suggest two fundamental roles for astrocytes within the SCN: (1) to regulate and mediate glutamate released by retinal terminals throughout the neuronal network to facilitate photic signal transmission; (2) to contribute to synchronization between suprachiasmatic neurons.
