Social and goal-related foundations of interpersonal adaptation during joint action.

Collaborative motor interactions (joint actions) require relating to another person (social dimension) whose contribution is needed to achieve a shared goal (goal-related dimension). We explored if and how these dimensions modulate interactive behavior by exploring posterror interpersonal adaptations. In two experiments carried out in 2022 (₁ = 23; ₂ = 24, preregistered), participants played sequences of notes in turn-taking with a coactor either described as another participant or the computer (human vs.

Self-other distinction modulates the sense of self-agency during joint actions.

In daily life interactions, we achieve goals with partners through tight temporal coordination or sequential joint efforts. Is our individual sense of control over shared outcomes (sense of self-agency) the same as the one experienced when we act alone? Do we explicitly and implicitly feel like we are fully in control of the motor act even if the goal is finally achieved by our partner? To address these questions, we measured explicit and implicit sense of self-agency in individual and (coordinated or sequential) interactive contexts. We studied 42 healthy adult participants during active/passive button presses aimed at turning on a light bulb.

Pleasantness makes a good time: musical consonance shapes interpersonal synchronization in dyadic joint action.

Introduction: Music making is a process by which humans across cultures come together to create patterns of sounds that are aesthetically pleasing. What remains unclear is how this aesthetic outcome affects the sensorimotor interaction between participants.

Method: Here we approach this question using an interpersonal sensorimotor synchronization paradigm to test whether the quality of a jointly created chord (consonant vs.

Neuromodulation of the Left Inferior Frontal Cortex Affects Social Monitoring during Motor Interactions.

Motor interactions require observing and monitoring a partner's performance as the interaction unfolds. Studies in monkeys suggest that this form of social monitoring might be mediated by the activity of the ventral premotor cortex (vPMc), a critical brain region in action observation and motor planning. Our previous fMRI studies in humans showed that the left vPMc is indeed recruited during social monitoring, but its causal role is unexplored.
