Social Threat and Motor Resonance: When a Menacing Outgroup Delays Motor Response

Area of Science:

• Social Psychology
• Cognitive Neuroscience
• Human Behavior

Background:

• Motor resonance (MR) involves mirroring observed actions via motor system activation.
• Social factors, like group membership, are increasingly recognized as influencing MR.
• Understanding how social threat perception modulates MR is crucial for social cognition research.

Purpose of the Study:

• To investigate the impact of social threat perception on motor resonance.
• To examine how agent's group membership (ingroup vs. outgroup) and contextual cues (neutral vs. threatening objects) affect MR.
• To explore the interplay between social identity and threat in modulating observed movement responses.

Main Methods:

• Action observation paradigm utilizing MouseTracker technology for response measurement.
• Manipulation of agent's group membership (ingroup/outgroup) and contextual object valence (neutral/threatening).
• Recording of response times and computer mouse trajectories during action observation.

Main Results:

• Motor resonance was significantly higher for ingroup members compared to outgroup members, but only in the presence of threatening contextual cues.
• Outgroup member actions tended to delay participants' motor responses.
• Findings indicate an interaction effect between group membership and contextual threat on MR.

Conclusions:

• Motor resonance is modulated by the interaction of social group membership and perceived threat.
• Threat-elicited stereotypes may influence automatic motor responses during social perception.
• The study extends understanding of MR by highlighting the role of context-dependent social threat in modulating embodied cognition.
