Abstract

Mimicry has been ascribed affiliative functions. In three experiments, we used a newly developed social-affective mimicry task (SAMT) to investigate mimicry´s modulation by emotional facial expressions (happy, angry) and ethnic group-membership (White in-group, Black out-group). Experiment 1 established the main consistent effect across experiments, which was enhanced mimicry to angry out-group faces compared to angry in-group faces. Hence the SAMT was useful for experimentally investigating the modulation of mimicry. Experiment 2 demonstrated that these effects were not confounded by general aspects of response conflict, as a Simon task resulted in different response patterns than the SAMT. Experiment 2 and pooled analysis of Experiments 1 and 2 also corroborated the finding of enhanced mimicry to angry out-group faces. Experiment 3 tested whether this effect was related to perceptions of threat, by framing angry persons as physically threatening, or not. Selective enhancement of mimicry to out-group persons framed as physically threatening confirmed this hypothesis. Further support for the role of threat was derived from implicit measures showing, in all experiments, that black persons were more strongly associated with threat. Furthermore, enhanced mimicry was consistently related to response facilitation in the execution of congruent movements. This suggests that mimicry acted as a social congruency signal. Our findings suggest that mimicry may serve as an appeasement signal in response to negative affiliative intent. This extends previous models of mimicry, which have predominantly focused on its role in reciprocating affiliation. It suggests that mimicry might not only be used to maintain and establish affiliative bonds, but also to ameliorate a negative social situation.

  • Findings from a behavioral study suggest that interference control is modulated by contextual factors such as group membership and emotional facial expressions.

    “Findings from a behavioral study suggest that interference control is modulated by contextual factors such as group membership and emotional facial expressions (Rauchbauer, Majdandžić, Stieger, & Lamm, 2016).”

    The Experiment 1 Results and the pooled analysis of Experiments 1 and 2 locate the group-by-emotion effect in response facilitation on congruent trials, with no significant effects on incongruent trials. The General Discussion likewise says the modulation specifically affected facilitation rather than interference control; it notes a separate trend toward reduced response inhibition only when the situation was framed as personally threatening.

  • The N2 trend result of more negative amplitudes for angry out-group than angry in-group trials mirrored previous behavioral results in the SAMT.

    “Our N2 trend result of more negative amplitudes for angry out-group than angry in-group trials mirrored previous behavioral results in the SAMT (Rauchbauer et al., 2016).”
  • The study did not replicate previous behavioral results of enhanced regulation of automatic imitation for angry out-group compared with angry in-group faces.

    “We did not replicate previous behavioral results of enhanced regulation of automatic imitation for angry out-group compared with angry in-group faces (Rauchbauer et al., 2016).”
  • Automatic imitation has been shown to be modulated by social context cues.

    “Automatic imitation has been shown to be modulated by social context cues (see e.g.3–11)”
  • Stimuli were presented using two consecutive frames to simulate finger lifting movement, to minimise the influence of ERP component overlap induced by rapidly changing frames in the EEG/ERP signal.

    “Stimuli were presented using two consecutive frames to simulate finger lifting movement (as opposed to the set-up of the SAMT used in7,8 using 4 frames) to minimise the influence of ERP component overlap induced by rapidly changing frames in the EEG/ERP signal (Fig. 1).”

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.
