Introduction
My major area of research is the study of peer relations in child and adolescent social development. My major research objective is to complement traditional psychological individual differences approaches to children’s social status and social competence with a broader socio-ethological understanding of the impact of local affiliative niches (e.g. friendship relationships, affiliative subgroup membership) emerging from the social ecology and organization of the peer group.

Parental attitudes toward child socialization influence their child-rearing practices, the quality of parent-child relationships, and children’s developmental outcomes. The Modified Child Rearing Practices Questionnaire (CRPR-Q) has been widely used to assess parenting practices across children’s development. However, the few studies investigating...
Article
In human fission–fusion societies, ritualized non-linguistic signal exchanges that include gestures, vocalizations, and facial expressions are regularly observed at both arrivals (greetings) and departures (leave-takings). These communicative events play an important role in the formation and maintenance of social relationships. Wild chimpanzees al...
Article
Background Oxytocin (OXT) has attracted research interest for its potential involvement in many of the behavioural problems observed in childhood. Due to its logistical advantages, saliva is an attractive fluid to quantify neuropeptides in children. Salivary OXT has been suggested as a potential biomarker for psychopathology during childhood. Howev...

O processo de (re)subjetivação do trauma consiste na (re)significação da vivência do evento traumático a partir da experiência de cada indivíduo. Quando o insuportável da dor do indivíduo que vivenciou o acontecimento traumático não pode ser introjetada e simbolizada inviabiliza-se a condição de inscrição e subjetivação da experiência. Desta forma,...
Article
Comparative psychology provides important contributions to our understanding of the origins of human language. The presence of common features in human and nonhuman primate communication can be used to suggest the evolutionary trajectories of potential precursors to language. However, to do so effectively, our findings must be comparable across div...

Adolescents’ dyadic relationships are likely influenced by the cultural context within which they exist. This study applied a person‐oriented approach to examine how perceived support and negativity were manifested across youths’ relationships with mothers, fathers, and best friends, simultaneously, and how distinct relationship profiles were linke...
Article
Full-text available
Behavioral inhibition (BI) during the preschool years can be defined as a biologically-based wariness when exposed to novel people, situations and activities, and has been associated with an increased risk of developing anxiety symptoms. Although BI is not a unitary concept, to date, few studies aimed to characterize different subgroups of children...

Peer victimization is one of the most prominent problems during adolescence. Research has distinguished aggressive and non-aggressive victims; however, there are still significant drawbacks in understanding the social and family functioning of these different groups of victimized adolescents. This study aimed to compare social behavior and perceive...
Article
The hypothalamic nonapeptides oxytocin and vasopressin are important modulators of socio-affective behaviours in a wide variety of animal species, including humans. Nevertheless, there is little research addressing their possible roles on socio-affective dimensions of human behaviour across development, during which considerable behavioural and phy...

L’étude des représentations est au cœur de la théorie de l’attachement. Le concept de «modèle interne opérant» (MOI) a permis de nombreux développements théoriques et cliniques, inscrivant la théorie de l’attachement au cœur des théories psychodynamiques. Dans ce chapitre, nous décrirons les MOI e aborderons les questions de la stabilité et de la p...
