Méthode
18 dyades de mêmes sexes (10 dyades femmes) composes d’un coach
expert du mouvement
et un élève novice
Séquence de mouvements: 4 pas en avant, 4 montées de genoux, 4 vagues avec les bras, 4 uppercuts, 8 combinaisons
Condition 1: réaliser la séquence dos à dos / Condition 2: réaliser la sequence face à face, l’élève devant suivre le coach
Motion capture: système optoélectronique (18 caméras infrarouge, 100Hz)
Pour chaque séquence de mouvement, l’énergie cinétique globale était calculée.

Contexte
La synchronie est le premier degré de la coordination et de l’action jointe
Etre synchrone affecte de manière positive la relation au sein d’un dyade: augmentation du rapport [1]
Les dispositions pro-sociales des individus modulent cette synchronie [2]
En situation écologique, approche globale de la synchronie (via l’énergie cinétique et des modèles linéaires) [3]
Ces approches se limitent à l’étude de l’amplitude de la synchronie
Objectifs de l’étude
Analyser les liens entre traits de personnalité et caractéristiques de la latence de la synchronie
Tâche de coordination de mouvements fitness entre un coach et son élève
Mesure de trois traits à composantes interpersonnelles du Big Five : l’extraversion, l’agréabilité et le névrosisme

Résultats
Régressions multiples:
2 variables de latence: l’écart type et fréquence moyenne
1 modèle par trait de personalité
3 variables en entrée (personalité du coach, de l’élève, et interaction entre les deux)
Principal effet: névrosisme et l’écart type de la latence (56,7% de la variance expliquée)
Tendance: agréabilité des coachs et la fréquence moyenne de la latence
Conclusions
Les caractéristiques de la latence dependent en partie de certain traits de personalité
Le rôle de chacun des membres de la dyade module ces influences
Coach plus agréable diminue la fréquence d’oscillation de la latence
Coach moins névrotique par rapport à un élève plus névrotique (interaction) diminue l’écart
type de la latence

Kinematics fingerprints of leader and follower role-taking during cooperative joint actions

Performing online complementary motor adjustments is quintessential to joint actions since it allows interacting people to coordinate efficiently and achieve a common goal. We sought to determine whether, during dyadic interactions, signaling strategies and simulative processes are differentially implemented on the basis of the interactional role played by each partner. To this aim, we recorded the kinematics of the right hand of pairs of individuals who were asked to grasp as synchronously as possible a bottle-shaped object according to an imitative or complementary action schedule. Task requirements implied an asymmetric role assignment so that participants performed the task acting either as (1) Leader (i.e., receiving auditory information regarding the goal of the task with indications about where to grasp the object) or (2) Follower (i.e., receiving instructions to coordinate their movements with their partner's by performing imitative or complementary actions). Results showed that, when acting as Leader, participants used signaling strategies to enhance the predictability of their movements. In particular, they selectively emphasized kinematic parameters and reduced movement variability to provide the partner with implicit cues regarding the action to be jointly performed. Thus, Leaders make their movements more "communicative" even when not explicitly instructed to do so. Moreover, only when acting in the role of Follower did participants tend to imitate the Leader, even in complementary actions where imitation is detrimental to joint performance. Our results show that mimicking and signaling are implemented in joint actions according to the interactional role of the agent, which in turn is reflected in the kinematics of each partner.

Social Connection Through Joint Action and Interpersonal Coordination
Article

  • Apr 2009
The pull to coordinate with other individuals is fundamental, serving as the basis for our social connectedness to others. Discussed is a dynamical and ecological perspective to joint action, an approach that embeds the individual’s mind in a body and the body in a niche, a physical and social environment. Research on uninstructed coordination of simple incidental rhythmic movement, along with research on goal-directed, embodied cooperation, is reviewed. Finally, recent research is discussed that extends the coordination and cooperation studies, examining how synchronizing with another, and how emergent social units of perceiving and acting are reflected in people’s feelings of connection to others.

Windowed Cross-Correlation and Peak Picking for the Analysis of Variability in the Association Between Behavioral Time Series
Article
Full-text available
  • Sep 2002
Cross-correlation and most other longitudinal analyses assume that the association between 2 variables is stationary. Thus, a sample of occasions of measurement is expected to be representative of the association between variables regardless of the time of onset or number of occasions in the sample. The authors propose a method to analyze the association between 2 variables when the assumption of stationarity may not be warranted. The method results in estimates of both the strength of peak association and the time lag when the peak association occurred for a range of starting values of elapsed time from the beginning of an experiment.

If they move in sync, they must feel in sync: Movement synchrony leads to attributions of rapport and entitativity
Article
  • Feb 2011
  • SOC COGNITION
Coordinated behavior patterns are one of the pillars of social interaction. Researchers have recently shown that movement synchrony influences ratings of rapport, and the extent to which groups are judged to be a unit. The current experiments investigated the hypothesis that observers infer a shared psychological state from synchronized movement rhythms, influencing attributions of rapport and entitativity judgments. Movement rhythms of observed individuals are manipulated between participants (Experiment 1) or kept constant while the source of the emerging movement synchrony is manipulated (Experiment 2), and both rapport and perceived entitativity are measured. The findings support the assumption that movement synchrony increases attributed rapport and perceived entitativity. Furthermore, mediational analyses reveal that the effects of movement synchrony on perceived unity are not purely perceptual in nature, but caused by psychological inferences. Observers infer the degree to which individuals are a social unit from their movement rhythms.
