Abstract

A large body of research has provided evidence for the idea that individuals simulate the actions of others in their motor system. However, this research has focused almost exclusively on dyadic situations, hence ignoring the fact that social situations often require that the actions of multiple persons are simulated simultaneously. In the current study, we addressed this issue by means of a widely used automatic imitation task. In Experiment 1, it is shown that individuals automatically imitate the actions of 2 agents at the same time. More specifically, the results indicate that 2 identical observed movements produce a stronger imitation effect, whereas 2 different observed movements produce 2 opposite imitation effects that cancel each other out. In Experiment 2, it is shown that the effects obtained in Experiment 1 cannot be explained in terms of attentional capture. Instead, the results point toward an explanation in terms of ideomotor theory. The finding that observers simultaneously represent the actions of multiple agents in their motor system allows for a better understanding of social interaction beyond the dyad.

  • Seeing one congruent and one incongruent action produces concurrent facilitation and interference effects that cancel each other out.

    “It was argued that seeing one congruent and one incongruent action produced a concurrent facilitation and interference effect that subsequently canceled out each other (Cracco et al., 2015).”

  • The motor system can simultaneously represent multiple observed actions, whether those actions are identical or different.

    “Together, this research indicates that the motor system is able to simultaneously represent multiple observed actions, regardless of whether these actions are identical or different actions.”

  • Automatic imitation comprises both a facilitation effect and an interference effect.

    “Indeed, it is well-established in the literature that automatic imitation comprises both a facilitation and an interference effect (Brass et al., 2000;Cracco et al., 2015;Genschow et al., 2017).”

  • In a study with two hands performing two different actions, one congruent and one incongruent, response times could not be distinguished from a neutral condition with no hand action.

    “The first study found that response times when two hands performed two different actions, one congruent and one incongruent, could not be distinguished from response times when neither hand performed an action.”

  • Seeing two hands performing the same action produces stronger corticospinal excitability and stronger imitation than seeing one hand performing a single action.

    “research looking at automatic imitation of multiple agents has shown that seeing two hands performing the same action elicits stronger corticospinal excitability (Cracco, De Coster, Andres, & Brass, 2016) and therefore stronger imitation (Cracco & Brass, 2018a;Cracco, De Coster, Andres, & Brass, 2015) than seeing one hand performing a single action.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
