• [hal-03130944] Sensorimotor Contingencies as a Key Drive of Development: From Babies to Robots

  4 février 2021

  Much current work in robotics focuses on the development of robots capable of autonomous unsupervised learning. An essential prerequisite for such learning to be possible is that the agent should be sensitive to the link between its actions and the consequences of its actions, called sensorimotor contingencies. This sensitivity, and more particularly its role as a key drive of development, has been widely studied by developmental psychologists. However, the results of these studies may not necessarily be accessible or intelligible to roboticians. In this paper, we review the main experimental data demonstrating the role of sensitivity to sensorimotor contingencies in infants’ acquisition of four fundamental motor and cognitive abilities: body knowledge, memory, generalization, and goal-directedness. We relate this data from developmental psychology to work in robotics, highlighting the links between these two domains of research. In the last part of the article we present a blueprint architecture demonstrating how exploitation of sensitivity to sensorimotor contingencies, combined with the notion of “goal,” allows an agent to develop new sensorimotor skills. This architecture can be used to guide the design of specific computational models, and also to possibly envisage new empirical experiments.
• [hal-04353159] Human perception of cats' communicative cues: human-cat communication goes multimodal

  19 décembre 2023

  As a central key to apprehend the human-cat relationship, the question of how humans decode the behaviours expressed by their feline companions has drawn scientists’ attention in the past decades. To this point, previous studies have not investigated humans’ understanding of cats’ communicative cues in a multimodal perspective. While communication generally implies multiple channels, the influence of signal modality as relates to human-cat communication, is still poorly understood. Therefore, the primary aim of the present study was to investigate whether people can identify cats’ communicative information using unimodal (visual or vocal) and bimodal (visual and vocal) signals. Participants (n=630) were recruited via online advertisement on social media. Each participant viewed 24 carefully operationalised video clips of cats in different emotional/behavioural conditions. Four categories were included: contentment, discontentment, solicitation (food or attention) and predatory behaviour. Clips were presented as vocal only, visual only, or bimodal (visual and vocal cues). Video clips showing a bimodal expression were identified with the highest score (91,8% of correct ratings) compared with the visual only (87,3%) and the vocal only (72,2%). All modalities considered, contentment returned the highest identification score (90,1% correct), followed by solicitation (87,2%), then predatory behaviour (86,3%). Discontentment was the most difficult behaviour to be correctly identified (71,6%). Finally, for all behavioural categories and modalities, professionals working with animals returned a higher score than lay people (86.2% vs 82.9%). Taken together, our data underline the influence of the signal modality on interspecific communication between cats and humans. Information emitted by cats as a bimodal signal (visual and vocal) is better understood by humans than visual signals. The most difficult to decipher for humans are vocal signals emitted alone. A better understanding of humans’ abilities to understand their feline counterparts, could potentially help pet owners, and animal care practitioners to optimise cat care and welfare.
• [hal-03861918] How’s my kitty? Acoustic parameters of cat-directed speech in human-cat interactions

  20 novembre 2022

  In Western cultures, humans tend to use a specific kind of speech when talking to their pets, characterised, from an acoustical point of view, by elevated pitch and greater pitch modulation. Pet-directed speech (PDS), which has been mainly studied in dogs, shares some acoustic features with infant-directed speech (IDS), used when talking to young children. The purpose of this study was to test the hypothesis that adult humans also modify characteristics of their voice when talking to a cat. We compared acoustic parameters of speech directed to cats (CDS) and speech directed to adult humans (ADS). In a first experiment, we compared ADS and CDS utterances of male and female participants, addressing cats through video recordings, under controlled laboratory conditions. Both men and women used a higher pitch (mean fundamental frequency, or mean F0) in CDS vs. ADS. The second experiment was conducted under conditions allowing direct cat-human interactions, in a cohort of women. Once again, mean F0 was significantly higher in CDS vs. ADS. Overall, these data confirm our hypothesis that humans change the way they speak when addressing a cat, mainly by increasing the pitch of their voice. Further research is needed to fully investigate specificities of this speech.
• [hal-05036469] The impact of humor on infant social learning: Insights from social gaze, heart rate variability, and laughter

  16 avril 2025

  Humor is a universal aspect of human culture, serving both social and cognitive functions. This study investigates humor's influence on infant learning, focusing on physiological, behavioral, and emotional responses. Building on previous research, we examined three questions: (1) Does humor affect infants' behaviors during a social learning task, such as looking, laughing, and smiling? (2) Does humor enhance learning, and is this effect age-dependent? (3) Can arousal, measured by heart rate variability (HRV), explain the relationship between humor and learning? We tested 88 infants aged 14–22 months, exposing them to either a humorous or neutral demonstration of a tool-use task. We assessed infants’ performance after demonstration and coded social gazes and emotional reactions. We also analyzed physiological arousal indicators, namely heart rate variability (HRV), through a connected wristband. Our analyses revealed that infants exposed to humorous demonstrations showed enhanced learning compared to those in the neutral condition, independently of whether they laughed or not. This suggests that laughing does not mediate the effect of humor on learning. Additionally, infants in the humorous condition looked more at the experimenter, which could indicate increased engagement or attentional processes. Finally, our HRV analyses revealed that infants who succeeded in the task exhibited higher HRV than those who did not. This study is the first to explore the mechanisms underlying humor’s effect on infant learning, emphasizing its complexity and the need for a multidimensional approach integrating cognitive, behavioral, and physiological factors.
• [hal-03636219] Comment les adolescents perçoivent-ils la relation avec leur camarade préféré(e) ?

  9 avril 2022

  Le premier objectif de cette recherche était d’apporter un soutien empirique à un modèle tridimensionnel de la perception qu’ont les adolescents de la relation avec leur camarade de classe préféré. Les trois dimensions étaient : l’attachement émotionnel au camarade, le sentiment qu’il serait prêt à apporter son aide pour réussir une activité scolaire, et le fait de s’attendre à ce qu’il offre son soutien en cas d’agression par d’autres élèves. Le deuxième objectif était de tester des hypothèses concernant les facteurs de variation de cette perception. Dans le cadre d’une enquête nationale, un échantillon représentatif des élèves français en classe de 3ème, âgés en moyenne de 15 ans et 4 mois, a répondu à un questionnaire destiné à évaluer cette perception. Une analyse factorielle confirmatoire (AFC) indique que le modèle tridimensionnel est bien ajusté aux réponses des élèves. Les trois sous-échelles sont positivement mais modérément inter-corrélées. Une analyse multivariée de la variance a révélé que la relation avec le camarade de classe préféré est mieux perçue par les filles que par les garçons, qu’elle est évaluée à un niveau plus élevé lorsque ce camarade est le meilleur ami en dehors du collège et aussi lorsque cette préférence n’est pas trop récente.
• [hal-04424300] Adolescent educational and occupational anxiety: A three-dimensional model to fit into an attachment framework

  10 juillet 2024

  We propose a model of the anxiety adolescents experience about their educational and occupational future that includes three topics they worry about: (a) career failure, (b) parental disappointment, and (c) separation from loved ones to achieve one’s career. A total of 16,663 15-year-old French participants filled out a new anxiety questionnaire and other self-reports. Factor analyses showed that all three topics belong to the same type of anxiety, and suggested that the adolescents’ fear about their career is closely interwoven with parental attachment. This new kind of anxiety varied across gender and was correlated with school-adjustment and personality variables.

• [hal-03636218] Les peurs des adolescents concernant leur avenir scolaire et professionnel : structure et variations selon le niveau scolaire, le sexe et la classe sociale

  9 avril 2022

  Les peurs des adolescents concernant leur avenir scolaire et professionnel 2 Les peurs des adolescents concernant leur avenir scolaire et professionnel : structure et variations selon le niveau scolaire, le sexe et la classe sociale. Résumé : La présente recherche vise à valider auprès d'adolescents un nouveau construit psychologique : l'anxiété suscitée par l'avenir scolaire et professionnel. Les résultats suggèrent que ce motif général d'anxiété se décline en trois motifs spécifiques : la peur d'échouer, la peur de décevoir ses parents, et la peur de s'éloigner de ses autruis significatifs, dans le cadre de ses parcours scolaire et professionnel. La force de ces motifs d'anxiété présente des différences significatives selon la classe sociale, le sexe et les performances scolaires. Les analyses de régression multiple révèlent que les différences persistent en dépit du contrôle du niveau scolaire. Cette anxiété peut être interprétée comme une composante d'un habitus de classe sociale ou de rôle sexué.
• [hal-04035198] Intensity seeking and novelty seeking: Their relationship to adolescent risk behavior and occupational interests

  17 mars 2023

  The aim of this study was to test the hypothesis that individual differences in sensation seeking account for adolescents' risk behavior and vocational interests. We relied on Arnett's (1994) conceptualization of sensation seeking as involving a need for intensity and a need for novelty, neither of which includes the willingness to take risks. Self-report scales measuring intensity seeking, novelty seeking, impulsiveness, risk behavior and vocational interest were administered to 636 adolescents. New scales measuring intensity seeking (IS) and novelty seeking (NS) were used. Regression analyses showed that IS and to a lesser extent NS accounted for a small part of variance of risk behavior, independent of impulsiveness. IS and NS accounted for vocational interests. The discussion emphasizes the importance of disentangling sensation seeking as a trait from willingness to take risks when one intends to analyse the effect of the former on risk behavior.
• [hal-04035310] Social anxiety with peers in 9- to 14-year-olds. Developmental process and relations with self-counsciousness and perceived peer acceptance

  17 mars 2023

  Studied the development and psychological correlates of social anxiety with peers in early adolescence, and whether there were age and gender differences. 508 French 4th–9th graders completed questionnaires assessing their perception of peer-related social anxiety, and the social cognitive dimensions of inward and outward self-consciousness and perceived peer acceptance. Results show that overall, there was a decreasing tendency with age for social anxiety and inward self-consciousness, although the participants increasingly perceived themselves to be neglected by their peers. Analyses suggested that inward self-consciousness, outward self-consciousness, and perceived peer acceptance contribute independently to social anxiety. The only sex difference in social anxiety was higher fear of negative evaluation among girls. Boys scored slightly higher than girls on perception of peers as liking them. These results may suggest which educational and clinical methods are most appropriate for helping adolescents who face high social anxiety.
• [hal-04035254] Preadolescents' Recognition of Faces of Unfamiliar Peers: The Effect of Attractiveness of Faces

  17 mars 2023

  The authors examined preadolescents' ability to recognize faces of unfamiliar peers according to their attractiveness. They hypothesized that highly attractive faces would be less accurately recognized than moderately attractive faces because the former are more typical. In Experiment 1, 106 participants (M age =10 years) were asked to recognize faces of unknown peers who varied in gender and attractiveness (high- vs. medium-attractiveness). Results showed that attractiveness enhanced the accuracy of recognition for boys' faces and impaired recognition of girls' faces. The same interaction was found in Experiment 2, in which 92 participants (M age =12 years) were tested for their recognition of another set effaces of unfamiliar peers. The authors conducted Experiment 3 to examine whether the reason for that interaction is that high- and medium-attractive girls' faces differ more in typicality than do boys' faces. The effect size of attractiveness on typicality was similar for boys' and girls' faces. The overall results are discussed with reference to the development of face encoding and biological gender differences with respect to the typicality of faces during preadolescence.
• [hal-01704319] Mate preferences in female canaries (Serinus canaria) within a breeding season

  8 février 2018

  Divorce and remating in birds can be described as strategies used to enhance reproductive success. Mate switching often occurs because pairs failed to brood at least one chick during the previous breeding season. In the present study, we evaluated the influence of reproductive success on female preferences in domesticated canaries (Serinus canaria). For that purpose, females previously paired and having reared young were placed in a choice test situation: They were allowed to choose between their previous mate and a familiar male (a male neighbor during the breeding period). During these choice tests, females tended to stay near their previous mate longer than near a male neighbor when their reproductive success was " good " (at least two chicks). On the other hand, females with " poor " reproductive success (one chick) did not show a preference for their previous mate. Furthermore, in the present study, we observed that during choice tests males reacted to the presence of their previous mate in a particular way, by gathering nest material. This behavior was more scarcely observed in neighbor males which, on the contrary, sang significantly more than previous mates did.
• [hal-04931960] Adolescents' sociosexual orientation is related to attachment to their same-sex parent

  6 février 2025

  We set out to show that sociosexual orientation (SSO) and erotophilia are two different traits that can be evidenced as early as middle adolescence, and to examine their associations with attachment to parents. Self-report scales measuring SSO, erotophilia, and attachment to the mother and the father were administered to 289 12- to 17-year-olds. Based on an exploratory factor analysis, SSO and erotophilia are two different, consistent dimensions in this age range. A six-month test-retest revealed a moderate-to-high rank-order stability of the two traits, which were positively and moderately correlated. Boys scored higher than girls on both traits. During the six-month interval between T1 and T2, erotophilia increased whereas SSO did not change. Regression analyses showed that a positive perception of attachment to the same-sex parent among boys accounted for SSO, regardless of perceived attachment to the other-sex parent. This held true for girls also, but to a lesser extent. In the discussion, we emphasize the differences between boys' and girls' mating behavior, and the differences between attachment to same-sex vs other-sex parents as possible influences on SSO.
• [hal-04931213] Ségrégation de sexe et socialisation entre élèves de collège au Cameroun. Filles et garçons à part mais en accord sur la répartition des rôles sexués.

  5 février 2025

  Le premier objectif était de savoir si à l’adolescence les relations entre élèves camerounais étaient marquées par la ségrégation de sexe. Le deuxième consistait à analyser dans quelle mesure les réputations de dominance et de prosocialité rendaient compte de l’acceptation sociale. 358 élèves de collège ont répondu à un questionnaire. Devant citer leurs préférés, ils ont choisi majoritairement des condisciples de leur sexe. Chez les filles les réputations de prosocialité et de dominance contribuent à l’acceptation sociale, chez les garçons seule leur réputation de prosocialité y contribue. On obtient les mêmes résultats en se centrant sur les citations provenant des pairs de même sexe. Ces résultats sont interprétés dans le contexte des rôles sexués au Cameroun.
• [hal-02890126] Diversity of romantic experiences in late adolescence and their contribution to identity formation

  11 février 2025

  Romance constitutes a central experience in adolescence, which can take several forms including (a) serious romance with a steady partner, (b) casual and short-lived dating, and (c) pending experiences of romantic thoughts and attempts. Using a three-way longitudinal design, the present study examined the gender differences and developmental changes of these romantic experiences, and their cross-lagged associations with identity processes, throughout one year in late adolescence. 389 students (63% girls) filled out questionnaires about their romantic experiences and identity processes. Girls reported more serious romance than did boys, who reported more casual dating and pending experiences. Serious romance increased over the year for both genders, whereas casual dating and pending experiences continued to rise only for boys. The cross-lagged model highlighted that serious romantic experience positively predicted identity commitments and exploration in depth, whereas identity exploration in breadth positively predicted casual dating. This pattern was stable over the three time-points and across gender and age groups. Overall, this study invites consideration of more diverse romantic experiences than those associated with tangible involvement. We discuss the contribution of romantic experiences to the identity dynamic
• [hal-01478457] L'éthique animale au croisement des perspectives de recherche entre éthologie et philosophie

  28 février 2017

  Des recherches conduites récemment en éthologie tendent à considérer les animaux comme des agents moraux. Ils ne concernent que peu d’espèces, primates surtout, et étudient essentiellement les comportements liés à l’empathie et le sentiment d’injustice. Ces deux thématiques coïncident avec certains travaux menés en psychologie et en philosophie morales qui suggèrent que notre capacité morale s’appuie sur au moins deux principales sous-capacités consacrées respectivement à un sens du juste et à un sens du bon. Ces recherches influencent notre manière de concevoir la morale et notre relation avec les animaux.
• [hal-01704549] Les premiers pas dans la langue

  8 février 2018

  L’enfant qui ne produit pas de mot à la naissance porte néanmoins en lui un savoir implicite concernant le langage, qui va s’actualiser progressivement grâce à des capacités perceptives fonctionnelles dès son arrivée au monde. Sans les mots, l’enfant a donc déjà le pouvoir de communiquer, de se faire entendre et d’analyser le discours qu’on lui adresse. Il commence par identifier le système phonologique de sa langue puis tente presque immédiatement de structurer ses productions vocales dès qu’il a le pouvoir d’émettre des sons. Ces premières émissions sonores témoignent tout simplement de l’humanité qui le caractérise. Si les chercheurs s’interrogent toujours à propos des processus à l’origine de l’acquisition du langage, tous reconnaissent cependant que les enfants acquièrent leur langue maternelle en un temps record et que cette acquisition repose sur des capacités perceptives présentes dès la naissance. <b>Plan</b> Du bain utérin au bain linguistique Le babillage, la langue de bébé Les premiers mots Conclusion

• [hal-02474536] Maternal presence influences vocal development in the Japanese quail ( Coturnix c. japonica )

  19 octobre 2020

  Social influences on vocal development of young birds have been widely studied in oscine songbirds who learn to sing by vocal imitation of conspecifics, mainly male adults. In contrast, vocal development of non-vocal learners such as Galliformes is considered as being under strong genetic influence and independent of the social environment. In this study, we investigated the role of the mother on the vocal development of young Japanese quail (Coturnix coturnix japonica). We compared the vocal development of mothered and non-mothered chicks during the first 21 days of life. We analysed the structural changes of two vocalisations: a) the rally call, emitted during long-distance communication and in stressful situations, b) the contact call, emitted during short-distance communication when chicks are in visual and/or auditory contact with congeners. We showed that temporal and spectral structures of the two types of calls changed during development and differed between mothered and nonmothered chicks. These results demonstrate that maternal presence influences the vocal development of the young in the Japanese quail. Even if the adaptive value of such changes was not assessed, these results highlight that plasticity of vocalisations in species considered as non-vocal learners has been underestimated.
• [hal-04498355] Social patterning of childhood overweight in the French national ELFE cohort

  11 mars 2024

  Abstract An inverse social gradient in early childhood overweight has been consistently described in high-income countries; however, less is known about the role of migration status. We studied the social patterning of overweight in preschool children according to the mother’s socio-economic and migration background. For 9250 children of the French ELFE birth cohort with body mass index collected at age 3.5 years, we used nested logistic regression to investigate the association of overweight status in children with maternal educational level, occupation, household income and migration status. Overall, 8.3% (95%CI [7.7–9.0]) of children were classified as overweight. The odds of overweight was increased for children from immigrant mothers (OR 2.22 [95% CI 1.75–2.78]) and descendants of immigrant mothers (OR 1.35 [1.04–2.78]) versus non-immigrant mothers. The highest odds of overweight was also observed in children whose mothers had low education, were unemployed or students, or were from households in the lowest income quintile. Our findings confirm that socio-economic disadvantage and migration status are risk factors for childhood overweight. However, the social patterning of overweight did not apply uniformly to all variables. These new and comprehensive insights should inform future public health interventions aimed at tackling social inequalities in childhood overweight.

  L'éthologie, au-delà du strict domaine de l'étude du comportement, s'étend aujourd'hui aux travaux sur la cognition, les émotions et les affects. Durant les cinquante dernières années, des approches aussi abondantes que variées ont ainsi permis d'aborder le déterminisme de la vie de relation des animaux. Cette histoire a été émaillée par maintes controverses sur les continuités et discontinuités entre l'homme et l'animal. La conception toute récente d'un animal hédonique permet de reconsidérer la vie subjective des animaux.

• [hal-02326354] Comment le bébé accède-t-il à la notion d’outil ?

  22 octobre 2019

  L’utilisation d’un outil permet de dépasser les limites de son propre corps pour interagir avec l’environnement. Après avoir appris à contrôler sa main pour prendre des objets, le bébé découvre peu à peu qu’un objet peut permettre d’agir sur un autre objet. Dans cet article nous nous intéressons à la fonction particulière de l’outil qui permet de rapprocher un objet présenté hors de portée. Nous passons d’abord en revue les comportements précurseurs de cette habileté, comme l’utilisation de moyens intermédiaires pour atteindre un but secondaire (means-end), ainsi que les premières études consacrées à l’utilisation d’outil pour rapprocher un objet. Dans un deuxième temps nous posons la question des mécanismes sous-jacents à la découverte de cette utilisation de l’outil à partir des résultats d’une étude où nous avons suivi quatre bébés pendant près d’un an à partir de 12 mois en leur présentant un jouet hors de portée et un râteau à portée de main. Nos résultats montrent que les bébés mettent plusieurs séances avant de comprendre l’utilité du râteau, séances pendant lesquelles soit ils explorent le râteau, soit ils quémandent le jouet, soit ils associent le râteau et le jouet mais pas pour essayer de rapprocher le jouet. Ce n’est que vers 18 mois, relativement soudainement, que les bébés ont semblé comprendre que le râteau pouvait leur permettre de rapprocher le jouet. Au vu des résultats, nous concluons que les mécanismes « essai-erreur » et apprentissage par observation nécessitent un certain niveau d’intuition de la solution pour être efficaces, mais que l’intuition elle-même nécessite une longue phase d’exploration qui permet dans un premier temps à la fois d’améliorer la manipulation du râteau (qui devient un prolongement de la main ?) et d’en découvrir les affordances.
• [hal-04035239] La coopération dyadique entre enfants de 5-6 ans : effets de la complexité cognitive et de l'activité motrice sollicitées par les situations de résolution de problème

  17 mars 2023

  The present study investigated the role of cognitive complexity and motor activity created by the problem-solving tasks on preschoolers' dyadic cooperative play. Fifteen 5-6 years old dyads were video-observed in three problem-solving tasks designed to contrast different levels of cognitive complexity and motor difficulties. Cooperation was defined by dyadic joint actions and emotional exchanges during problem-solving tasks as well as children's interactions outside the tasks. A micro-analysis of children's behaviors was realized on 3 minutes of video-observation in each condition. Results showed that the more the problem-solving task created motor activities, the more the children produced dyadic joint actions and had longer emotional exchanges. They also interacted more frequently outside the task. No differences were found when the cognitive complexity of tasks were compared. These results were discussed within Walton's framework (1945) suggesting a link between motor expressivity and cognitive development.

• [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-04531861] LA MUSICALITÉ EST-ELLE UN HÉRITAGE DE NOTRE HISTOIRE BIOLOGIQUE ? Une approche comparative et multidisciplinaire

  4 avril 2024

  La musicalité ( i.e. l’ensemble des capacités associées à la perception, à l’appréciation et la production musicale) est largement répandue chez notre espèce. Selon certains chercheurs, elle aurait évolué car elle favoriserait la survie et/ou la reproduction. Ainsi, les origines biologiques de la musicalité ont été étudiées dans la littérature, chez l’espèce humaine mais aussi chez d’autres espèces. Les études suggèrent des fonctions adaptatives, dont l’attractivité en tant que partenaire de reproduction, la communication mère-bébé, ou encore la cohésion des groupes sociaux. Dans cette revue comparative, nous présenterons les données existantes sur la musicalité chez les espèces humaine et non-humaines pour chacune des fonctions évoquées ci-dessus. Nous discuterons ensuite la convergence évolutive de la musicalité chez certaines espèces ainsi que son origine biologique.

• [hal-03114162] Combinatory sound object play in cockatiels: a forerunner of music?

  17 septembre 2024

  An interest in producing sounds during play behaviour might be a forerunner for music. Thus, we explored object play behaviour involving sounds in cockatiels (Nymphicus hollandicus). We provided them with several objects producing sounds and recorded sound production, spontaneous warbles and drumming during breeding, pre-and post-breeding. Birds manipulated the objects in a playful way. They manipulated them less during breeding than during pre-and post-breeding, but the proportion of manipulations producing sounds were higher during post-breeding and breeding than during pre-breeding. Males manipulated the objects more frequently and produced more sounds than females. Youngsters manipulated the objects more than adults. One bird repeatedly put a bell on a xylophone; we discuss several possible explanations for the behaviour, including tool use. Only males warbled and drummed, and during breeding only. Our results suggest an enriching effect of the objects on the birds. Many aspects of musicality remain to be studied.

  28 février 2017

  Pourquoi les femmes sont-elles sujettes à la ménopause ? Cette question reste en grande partie mystérieuse. Logiquement, les mécanismes biologiques de l'évolution font en sorte que les invididus ne vivent guère longtemps au-delà de leur période de procréation. La ménopause est ainsi rarissime, et ne se produit que dans l'espèce humaine, ainsi que chez deux cétacés : l'orque et le globicéphale. Ce qui a poussé les biologistes à s'intéresser aux orques, dans le but de comprendre pourquoi leurs femelles sont ménopausées. Des observations nouvelles viennent ainsi d'être réalisées et publiées par une équipe de chercheurs de l'Université d'Exeter en Grande-Bretagne associée à des spécialistes des baleines de l'État de Washington, aux États-Unis. Ces observations pourraient expliquer pourquoi les femelles de rares espèces (dont la nôtre) ont une durée de vie largement supérieure à leur période de reproduction. Les orques vivent en troupes d'une quinzaine d'individus unis par des liens sociaux riches et complexes. Remarquablement intelligentes, parfois qualifiées de « baleines tueuses », les femelles âgées tiennent une place particulière que l'on peut observer dans des scènes typiques de la vie de ces animaux, où une orque conduit par exemple ses fils et ses filles, déjà d'âge adulte, vers un banc de saumons. Les jeunes adultes, parfaitement capables de chasser, se laissent mener sur la trajectoire du banc de poissons, dont ils semblent ignorer l'emplacement exact.

La ménopause est ainsi rarissime, et ne se produit que dans l'espèce humaine, ainsi que chez deux cétacés : l'orque et le globicéphale. Ce qui a poussé les biologistes à s'intéresser aux orques, dans le but de comprendre pourquoi leurs femelles sont ménopausées. Des observations nouvelles viennent ainsi d'être réalisées et publiées par une équipe de chercheurs de l'Université d'Exeter en Grande-Bretagne associée à des spécialistes des baleines de l'État de Washington, aux États-Unis. Ces observations pourraient expliquer pourquoi les femelles de rares espèces (dont la nôtre) ont une durée de vie largement supérieure à leur période de reproduction. Les orques vivent en troupes d'une quinzaine d'individus unis par des liens sociaux riches et complexes. Remarquablement intelligentes, parfois qualifiées de « baleines tueuses », les femelles âgées tiennent une place particulière que l'on peut observer dans des scènes typiques de la vie de ces animaux, où une orque conduit par exemple ses fils et ses filles, déjà d'âge adulte, vers un banc de saumons. Les jeunes adultes, parfaitement capables de chasser, se laissent mener sur la trajectoire du banc de poissons, dont ils semblent ignorer l'emplacement exact. Tout se passe comme si la...
• [hal-04500856] Toward a multimodal and continuous approach of infant-adult interactions

  12 mars 2024

  Abstract Adult-infant early dyadic interactions have been extensively explored by developmental psychologists. Around the age of 2 months, infants already demonstrate complex, delicate and very sensitive behaviors that seem to express their ability to interact and share emotions with their caregivers. This paper presents 3 pilot studies of parent-infant dyadic interaction in various set-ups. The first two present longitudinal data collected on two infants aged between 1 and 6 months and their mothers. We analyzed the development of coordination between them, at the motor and at the vocal level. The 3rd pilot study aims to explore interpersonal coordination in both vocal behavior and motor activity for one infant and his mother at 2, 4 and 6 months. These pilot studies however leave a number of questions open concerning developmental changes and infants’ progressive mastery of interaction. We identify areas worth examining and try to tease out specific issues that may help develop new methodological pathways for the study of early naturalistic social interaction. We assume that a continuous, rather than discrete, approach would better capture the changes taking place in the various communicative modalities, while also displaying each dyad’s specificity and the narrative dimension of social engagement between infants and caregivers.
• [hal-04035290] The Development of Gender Schemata About Heterosexual and Homosexual Others During Adolescence

  17 mars 2023

  Perceptions of heterosexual and homosexual individuals were investigated among 55 male and 60 female French 11.0–22.1 yr olds, divided into 3 mean age groups of 12-, 16-, and 20 yr olds. Participants described heterosexual and homosexual males and females with typical masculine and feminine personality traits. Overall, they perceived heterosexual males as having more masculine traits than homosexual males. The 16- and 20-yr-olds perceived homosexual males as more feminine than heterosexual males, whereas the reverse was observed in 12-yr-olds. Furthermore, the 1 2-yr-olds perceived heterosexual females as more feminine than homosexual females, a difference that disappeared in the older age groups. Results support the view of early adolescence as a crucial period in the development of gender schemata about sexually significant others.
• [hal-03919211] Premises of social cognition: Newborns are sensitive to a direct versus a faraway gaze

  2 janvier 2023

  Previous studies evidenced that already from birth, newborns can perceive differences between a direct versus an averted gaze in faces both presented in static and interactive situations. It has been hypothesized that this early sensitivity would rely on modifications of the location of the iris (i.e. the darker part of the eye) in the sclera (i.e. the white part), or that it would be an outcome of newborns’ preference for configurations of faces with the eye region being more contrasted. One question still remains: What happens when the position of the iris is not modified in the sclera, but the look is ‘faraway’, that is when the gaze is toward the newborns’ face but above his or her own eyes? In the present study, we tested the influence of a direct versus a faraway gaze (i.e., two gazes that only differed slightly in the position of the iris on the vertical axis and not on the horizontal axis) on newborns’ face recognition. The procedure was identical to that used in previous studies: using a familiarization-test procedure, we familiarized two groups of newborns (N = 32) with videos of different talking faces that were presented with either a direct or a faraway gaze. Newborns were then tested with photographs of the face seen previously and of a new one. Results evidenced that newborns looked longer at the familiar face, but only in the direct gaze condition. These results suggest that, already from birth, infants can perceive slight differences of gazes when someone is addressing to them.
• [hal-04045804] Adolescents’ Attachment to Parents and Peers: Links to Young Adulthood Friendship Quality

  25 mars 2023

  Few studies have been carried out on emerging adults' friendships and on their developmental roots. Research suggests that in adolescence, both attachment to parents and attachment to peers play a role in future socio-emotional development. The aim of the present study was to compare attachment in these two types of relationships in adolescence according to gender and test whether they respectively predicted the perception of best friendship in early adulthood. A sample of 83 participants (49 girls) was seen in early adolescence (M = 13.66 years, SD = 0.64) and 7 years later (mean age = 21.15 years, SD = 0.83). At T1, participants completed the Inventory of Parent and Peer Attachment, which measures attachment using three subscales (communication, alienation and trust) and one global security score. At T2, they completed the McGill Friendship Questionnaire. Results show that in adolescence, boys report higher security with parents compared to peers (mainly due to better communication), unlike girls who obtain higher scores with peers. Longitudinal findings reveal that alienation in the relation with parents is what best predicts friendship quality in early adulthood. These findings underline the specific internal working models at play in socio-emotional development and the way gender differences evolve from adolescence to early adulthood. Highlights: Contrary to female adolescents, males reported higher security with parents compared to peers (mainly due to better communication). Female adolescents reported better communication with peers than males. No gender difference in friendship quality in emerging adulthood was found. Results suggest that the progressive broadening of attachment from parents to peers occurs earlier for girls than for boys. Alienation in the relation with parents in early adolescence predicts friendship quality in early adulthood. [ABSTRACT FROM AUTHOR]

• [hal-03484132] French handlers’ perspectives on Animal-Assisted Interventions

  24 mai 2023

  BackgroundAnimal-Assisted Interventions (AAI) are well implemented in human healthcare, in France as elsewhere; yet there are still difficulties in characterizing these practices and misconceptions about their mechanisms - little is known about the French practice of AAI and about the human-animal team.ObjectivesThis study aims to characterize AAI by exploring their specificities through French handlers’ perspectives.Material and methodAn online survey addressed to French handlers working in AAI with mainly one dog was carried out. This research included questions about their practice in AAI (registration status, beneficiaries, and animals) and their background (training in AAI, training in the medico-social field, training in animal behavior). We then examined a phenomenological understanding of handlers’ definitions of their practice in AAI, their motivations to work with these approaches, and the expectations of the human-animal team. We used an open coding strategy and created major themes from their answers.Results111 handlers participated in this study. The quantitative data highlighted a heterogeneity of handlers' profiles and professional backgrounds, although most profiles had previous training in healthcare. Five themes characterizing AAI emerged from the qualitative analysis: (1) AAI as additional approaches to care settings, (2) AAI as person-centered approaches, (3) the complementarity between handlers and their animal(s), (4) the shared role of mediator, and (5) handlers’ beliefs about the human-animal relationship related to their personal experiences. This survey allowed us to understand how the French use AAI and its role in the care system.ConclusionThe benefits of AAI are numerous both for care settings and for the caregivers mainly by making the care more humane. AAI seem to put the wellbeing of beneficiaries and the relationship with the caregiver at the center of the care. The complementarity of the human-animal team is the common feature of these practices and is critical to their success. Future interdisciplinary studies are required to explore the particularities of these interspecific approaches and the differences between countries.
• [hal-01478448] Male Song Quality Modulates c-Fos Expression in the Auditory Forebrain of the Female Canary

  28 février 2017

  In canaries, specific phrases of male song (sexy songs, SS) that are difficult to produce are especially attractive for females. Females exposed to SS produce more copulation displays and deposit more testosterone into their eggs than females exposed to non-sexy songs (NS). Increased expression of the immediate early genes c-Fos or zenk (a.k.a. egr-1) has been observed in the auditory forebrain of female songbirds hearing attractive songs. C-Fos immunoreactive (Fos-ir) cell numbers were quantified here in the brain of female canaries that had been collected 30min after they had been exposed for 60min to the playback of SS or NS or control white noise. Fos-ir cell numbers increased in the caudomedial mesopallium (CMM) and caudomedial nidopallium (NCM) of SS birds as compared to controls. Song playback (pooled SS and NS) also tended to increase average Fos-ir cell numbers in the mediobasal hypothalamus (MBH) but this effect did not reach full statistical significance. At the individual level, Fos expression in CMM was correlated with its expression in NCM and in MBH but also with the frequency of calls that females produced in response to the playbacks. These data thus indicate that male songs of different qualities induce a differential metabolic activation of NCM and CMM. The correlation between activation of auditory regions and of the MBH might reflect the link between auditory stimulation and changes in behavior and reproductive physiology.
• [hal-03484139] The State of Animal-Assisted Interventions in France: Is the IAHAIO Model Relevant?

  26 mars 2024

  Animal-assisted interventions (AAI) became more generalized in health care settings and their development in Europe is increasing. In France, the practice has grown in the absence of official recognition and regulation. In this context, we aim to identify the main characteristics of the French practice of AAI that can influence the establishment of a local regulation. Second, we aim to question the relevance of the model proposed by the International Association of Human-Animal Interaction Organizations (IAHAIO) distinguishing animal-assisted therapies (AAT) and (AAA) animal-assisted activities from the French practice of AAI. We interviewed 111 French handlers in AAI that work with at least one dog through an online questionnaire about their professional backgrounds and the main features of their practices of AAI (characteristics, beneficiaries, and animals). Our results indicated that AAI are at an important moment of expansion and are currently under autonomous regulation. Practices and handlers' backgrounds are heterogeneous, as well as training centers in AAI, which reflect the fragmentation of the field. This snapshot of the French practice of AAI underlined that regulations should focus first on a mandatory training, a common standard for each training center, and specific guidelines for each pathology and animal species involved. In addition, the influence of handlers' backgrounds on the type of AAI they practice must be taken into account in regulations. As animals are central in AAI, regulations should focus on their welfare and the certification of dogs to ensure both their safety and the safety of beneficiaries during sessions. Finally, the initial training in the medico-social field seems to influence the practices. Therefore, the common model distinguishing AAT and AAA could be a basis to regulate AAI in France, as in Italy. Indeed, our results underlined that a first categorization between AAI as a professional specialization or an independent profession could be useful. Still, whatever the type of practices, animal and beneficiary welfare should be at the center of regulations in a One Health perspective. As a result, the French government needs to support AAI development such as in other European countries (Sweden, Austria, and Italy) and should collaborate with handlers, organizations, health care facilities, animal professions, and scientists.
• [hal-01244841] Sex Differences in Language Across Early Childhood: Family Socioeconomic Status does not Impact Boys and Girls Equally

  17 décembre 2015

  Child sex and family socioeconomic status (SES) have been repeatedly identified as a source of inter-individual variation in language development; yet their interactions have rarely been explored. While sex differences are the focus of a renewed interest concerning emerging language skills, data remain scarce and are not consistent across preschool years. The questions of whether family SES impacts boys and girls equally, as well as of the consistency of these differences throughout early childhood, remain open. We evaluated consistency of sex differences across SES and age by focusing on how children (N = 262), from 2;6 to 6;4 years old, from two contrasting social backgrounds, acquire a frequent phonological alternation in French – the liaison. By using a picture naming task eliciting the production of obligatory liaisons, we found evidence of sex differences over the preschool years in low-SES children, but not between high-SES boys and girls whose performances were very similar. Low-SES boys' performances were the poorest whereas low-SES girls' performances were intermediate, that is, lower than those of high-SES children of both sexes but higher than those of low-SES boys. Although all children's mastery of obligatory liaisons progressed with age, our findings showed a significant impeding effect of low-SES, especially for boys.
• [hal-04952306] Decreased risk-proneness with increasing age in equally raised and kept wolves and dogs

  17 février 2025

  A basic mechanism of domestication is the selection for fearlessness and acceptance of humans as social partners, which may affect risk-taking behavior and the ability to use humans as social support, both at the behavioural and physiological levels. We combined behavioural observations with heart rate parameters (i.e., HR and heart rate variability, HRV) in equally raised and housed wolves and dogs to assess the responses to food offered in the vicinity of a potential stressor (an unknown spinning object) with and without social support from a familiar human. Based on previous studies on neophobia in wolves and dogs, we expected dogs to be less scared of the object, approach more quickly, show less ambivalent behaviour, lower HR, and higher HRV, than wolves, especially at the presence of a human partner. However, we found that mainly age and the presence of a familiar human affected the behaviour of our subjects: older wolves and dogs were generally bolder and faster to approach the food and the familiar human’s presence increased the likelihood of taking it. HR rate parameters were affected by age and the stage of the test. Wolves and dogs showed particularly high HRs at the beginning and end of the test sessions. We conclude that in our paradigm, wolves’ and dogs’ risk-proneness varied with age, rather than species. Additionally, the presence of a familiar human increased the motivation of both, dogs and wolves to take the food.
• [hal-04952642] Context-Specific Arousal During Resting in Wolves and Dogs: Effects of Domestication?

  17 février 2025

  <div><p>Due to domestication, dogs differ from wolves in the way they respond to their environment, including to humans. Selection for tameness and the associated changes to the autonomic nervous system (ANS) regulation have been proposed as the primary mechanisms of domestication. To test this idea, we compared two low-arousal states in equally raised and kept wolves and dogs: resting, a state close to being asleep, and inactive wakefulness, which together take up an important part in the time budgets of wolves and dogs. We measured arousal via cardiac output in three conditions: alone, with a familiar human partner, or with pack members (i.e., conspecifics). Specifically, we compared heart rate (HR) and heart rate variability (HRV) of six wolves and seven dogs. As patterns of resting can vary adaptively, even between closely related species, we predicted that dogs would be generally more aroused than wolves, because living with humans may come with less predictable contexts than living with conspecifics; hence, dogs would need to be responsive at all times. Furthermore, we predicted that due to the effects of domestication, emotional social support by familiar people would reduce arousal more in dogs than in equally human-socialized wolves, leading to more relaxed dogs than wolves when away from the pack. Overall, we found a clear effect of the interactions between species (i.e., wolf versus dog), arousal state (i.e., resting or awake inactive) and test conditions, on both HR and HRV. Wolves and dogs were more aroused when alone (i.e., higher HR and lower HRV) than when in the presence of conspecifics or a familiar human partner. Dogs were more relaxed than wolves when at rest and close to a familiar human but this difference disappeared when awake. In conclusion, instead of the expected distinct overall differences between wolves and dogs in ANS regulation, we rather found subtle context-specific responses, suggesting that such details are important in understanding the domestication process.</p></div>

• [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
