- PublicationMétadonnées seulementEndogenous oxytocin predicts helping and conversation as a function of group membership(2018-7-4)
; ; ; ; Humans cooperate with unrelated individuals to an extent that far outstrips any other species. We also display extreme variation in decisions about whether to cooperate or not, and the mechanisms driving this variation remain an open question across the behavioural sciences. One candidate mechanism underlying this variation in cooperation is the evolutionary ancient neurohormone oxytocin (OT). As current research focuses on artificial administration of OT in asocial tasks, little is known about how the hormone in its naturally occurring state actually impacts behaviour in social interactions. Using a new optimal foraging paradigm, the ‘egg hunt’, we assessed the association of endogenous OT with helping behaviour and conversation. We manipulated players' group membership relative to each other prior to an egg hunt, during which they had repeated opportunities to spontaneously help each other. Results show that endogenous baseline OT predicted helping and conversation type, but crucially as a function of group membership. Higher baseline OT predicted increased helping but only between in-group players, as well as decreased discussion about individuals’ goals between in-group players but conversely more of such discussion between out-group players. Subsequently, behaviour but not conversation during the hunt predicted change in OT, in that out-group members who did not help showed a decrease in OT from baseline levels. In sum, endogenous OT predicts helping behaviour and conversation, importantly as a function of group membership, and this effect occurs in parallel to uniquely human cognitive processes. - PublicationAccès libreEndogenous oxytocin predicts helping and conversation as a function of group membership.(2018-07-04T00:00:00Z)

- PublicationAccès libreThe language of cooperation: shared intentionality drives variation in helping as a function of group membership(2017-8-27)
; ; While we know that the degree to which humans are able to cooperate is unrivalled by other species, the variation humans actually display in their cooperative behaviour has yet to be fully explained. This may be because research based on experimental game-theoretical studies neglects fundamental aspects of human sociality and psychology, namely social interaction and language. Using a newoptimal foraging game loosely modelled on the prisoner’s dilemma, the Egg Hunt, we categorized players as either in-group or out-group to each other and studied their spontaneous language usage while they made interactive, potentially cooperative decisions. Both shared group membership and the possibility to talk led to increased cooperation and overall success in the hunt. Notably, analysis of players’ conversations showed that in-group members engaged more in shared intentionality, the human ability to both mentally represent and then adopt another’s goal, whereas out-group members discussed individual goals more. Females also helped more and displayed more shared intentionality in discussions than males. Crucially, we show that shared intentionality was the mechanism driving the increase in helping between in-group players over out-group players at a cost to themselves. By studying spontaneous language during social interactions and isolating shared intentionality as the mechanism underlying successful cooperation, the current results point to a probable psychological source of the variation in cooperation humans display. - PublicationAccès libreInteractional Competences in Institutional Settings: from School to the Workplace(: Palgrave Macmillan, 2017)
; ; ; - PublicationAccès libreOrganisation interactionnelle des récits conversationnels par des jeunes candidats lors d'un entretien d'embaucheComme en témoigne une abondante littérature sur le sujet, produire un récit conversationnel constitue un moyen de présentation de soi efficace dans le contexte d’un entretien d’embauche. Cependant, les mécanismes d’implémentation de ces récits dans l’interaction demeurent à ce jour largement sous-explorés. La présente étude s’inscrit dans le cadre d’un projet de recherche plus vaste, portant sur les compétences interactionnelles déployées en contexte institutionnel par des jeunes dans leur trajectoire entre l’école et leurs débuts dans le monde professionnel (Interactional Competences in Institutional Practices : Young People between School and the Workplace, subside FNS CRSII1_136291). De ce projet est issu un livre retraçant les grandes étapes de ce parcours (Pekarek Doehler, Bangerter, de Weck, Filliettaz, Gonzalez-Martinez & Petitjean, à paraître). L’objectif de notre recherche consiste ainsi à observer les mécanismes interactionnels qui sous-tendent les activités de récits conversationnels, dans des entretiens d’embauche impliquant des jeunes candidats inexpérimentés, postulant pour leur premier emploi. Le récit conversationnel est ici défini comme étant un récit d’expérience personnelle, constitué d’un enchaînement temporel d’événements, et référant à un moment unique situé dans le passé. L’observation de ce phénomène a été effectuée sur la base d’un corpus de données authentiques d’entretiens d’embauche, enregistrées sur un support audio-visuel, dans deux administrations publiques et une entreprise privée de Suisse romande. Ancrée dans une perspective interactionniste, cette recherche explore l’organisation interactionnelle des récits conversationnels produits par des jeunes candidats lors d’un entretien d’embauche, en observant les techniques et ressources déployées par les participants dans l’accomplissement d’activités de récit. Cette étude contribue à une meilleure compréhension du récit dans le contexte institutionnel de l’entretien d’embauche, et procure des clés aux candidats et aux recruteurs sur les mécanismes permettant de produire un récit valorisant des compétences pertinentes pour le poste., As extensively demonstrated in the literature, storytelling in job interviews is a pervasive means for self-presentation. However, how these stories are interactionally implemented is still under-explored. This study is part of a broader project, about interactional competences in institutional practices by young people in their trajectories between school and the workplace (Interactional Competences in Institutional Practices : Young People between School and the Workplace, SNF grant CRSII1_136291). This project yielded to a book recounting the main stages of this path (Pekarek Doehler, Bangerter, de Weck, Filliettaz, Gonzalez-Martinez & Petitjean, in press). The goal of this study aims to observe the interactional mechanisms underlying storytelling activities in job interviews involving inexperienced young candidates, applying for their first job. Conversational storytelling is defined here as a story about a personal experience, made of a temporally ordered sequence of events, and refering to a unique time in the past. The observation of this phenomenon has been made on a corpus of naturally occurring data of job interviews, audio-video recorded, in two public organisations and one private company of the french speaking part of Switzerland. Grounded in an interactionist perspective, this research explores the interactional organisation of storytelling by young candidates in job interviews, observing the technics and resources deployed by the interactants to accomplish storytelling activities. This study gives a better understanding of storytelling in the institutional context of job interviews, and provides some keys to both candidates and recruiters about the mechanisms by which producing a meaningful storytelling, highlighting relevant skills for the job.
