Joint actions are cooperative activities where humans coordinate their actions to achieve individual and shared goals. While the motivation to engage in joint action is clear when a goal cannot be achieved by individuals alone, we asked whether humans are motivated to act together even when acting together is not necessary and implies incurring add...

We investigated whether prescribing an agreement can result in optimal inter-individual integration of perceptual judgments in absence of verbal communication. Participants in pairs performed a localization task in a virtual 3D environment, where the goal was to make projections from an upper plane to the target on the bottom plane. Partners were p...

Predicting others' actions and inferring preferences from their choices is indispensable for successfully navigating social environments. Yet, the cognitive tools agents employ for prediction and decision may differ when involved in social interactions. When pursuing a goal individually, humans maximize utility by minimizing costs, while when engag...

Recent years have seen a growing interest in the question of whether and how groups of nonhuman primates coordinate their behaviors for mutual benefit. On the one hand, it has been shown that chimpanzees in the wild and in captivity can solve various coordination problems. On the other hand, evidence of communication in the context of coordination...

Recent research has demonstrated that two persons can optimally combine their observations to make better decisions when they can verbally communicate their confidence to each other. The present study investigated whether non-verbal interaction in a shared environment can be sufficient to achieve similar collective benefit. Pairs of individuals per...

Others’ perceptual judgments tend to have strong effects on our own, and can improve perceptual judgments when task partners engage in communication. The present study investigated whether individuals benefit from others’ perceptual judgments in indirect interactions, where outcomes of individual decisions can be observed in a shared environment. P...

Joint trial sequence. A reconstruction of a representative joint trial though the eyes of a participant manipulating the red pointer. On the first frame of the animation the red pointer is already in the location submitted as the first (T1) judgment. The text box was not visible during the experiment. (GIF)
