“…Previous work has suggested that imitation signals a desire to affiliate (Chartrand & Lakin, 2012) but positive effects of being imitated are not always seen (Hale & Hamilton, 2016a;Verberne, Ham, & Midden, 2015). Kinematic patterns can also signal informative intentions (McEllin, Sebanz, & Knoblich, 2018) or confidence (Patel, Fleming, & Kilner, 2012) which could be important here. It would also be interesting to understand the neural mechanisms of imitation as a social signal.…”

Humans frequently imitate each other's actions with high fidelity, and different reasons have been proposed for why they do so. Here we test the hypothesis that imitation can act as a social signal, with imitation occurring with greater fidelity when a participant is being watched. In a preregistered study, 30 pairs of naïve participants played an augmentedreality game involving moving blocks in space. We compared imitation fidelity between trials where the leader watched the followers' action, and trials where the leader did not watch. Followers imitated the trajectory height demonstrated by the leader, and critically, the strength of this correlation was greater in trials where the follower knew the leader was watching them. This suggests that followers spontaneously used imitation as a social signal in a nonverbal interaction task, supporting socio-communicative hypotheses of imitation.

“…While the agent exerts more effort in the longer push, the double push provides particularly strong cues about the agent's intention. Inferring intentions is a non-trivial computational task (Gao, Baker, Tang, Xu, & Tenenbaum, 2019) -a task that humans are extremely good at (McEllin, Sebanz, & Knoblich, 2018). Recent work has linked intentions to plans (Bratman, 2009;Shu, Kryven, Ullman, & Tenenbaum, 2020), and defined intended outcomes as those that made a difference to an agent's plan (Kleiman-Weiner et al, 2015).…”

When holding others morally responsible, we care about what they did, and what they thought. Traditionally, research in moral psychology has relied on vignette studies, in which a protagonist's actions and thoughts are explicitly communicated. While this research has revealed what variables are important for moral judgment, such as actions and intentions, it is limited in providing a more detailed understanding of exactly how these variables affect moral judgment. Using dynamic visual stimuli that allow for a more fine-grained experimental control, recent studies have proposed a direct mapping from visual features to moral judgments. We embrace the use of visual stimuli in moral psychology, but question the plausibility of a feature-based theory of moral judgment. We propose that the connection from visual features to moral judgments is mediated by an inference about what the observed action reveals about the agent's mental states, and what causal role the agent's action played in bringing about the outcome. We present a computational model that formalizes moral judgments of agents in visual scenes as computations over an intuitive theory of physics combined with an intuitive theory of mind. We test the model's quantitative predictions in three experiments across a wide variety of dynamic interactions between agent and patient.

“…Sensorimotor communication goes also beyond the body. For example, when driving a car, we can decelerate or move to the side of a road, to signal that we want to leave room to other drivers (Chater et al 2018;McEllin et al 2018;Pezzulo & Dindo 2011;Vesper et al 2011).…”

The target article does not address the neural mediation of complex social behavior. I review evidence that such mediation may be compatible with proposed Bayesian information-processing principles. Notably, however, such mediation occurs subcortically as well as cortically, concerns reward uncertainty and information uncertainty, and impacts culture via group-level payoff structures that define individualism and collectivism.
