This study shows that the mirror system enables us to understand others' potential actions without direct perception. This finding bridges symbolic communication and nonsymbolic interaction, highlighting the mirror system's role in shared intentionality.

Area of Science:

  • Cognitive Neuroscience
  • Social Psychology
  • Neuroscience

Background:

  • Traditional communication involves intentional, symbolic information exchange.
  • The mirror system facilitates nonsymbolic, nonintentional information exchange.
  • Bridging these domains is key to understanding joint action and shared intentionality.

Purpose of the Study:

  • Investigate the mirror system's role in representing others' potential actions.
  • Examine how individuals represent others' actions without perceptual cues.
  • Explore the link between mirror systems, co-representation, and joint action.

Main Methods:

  • Two experiments were conducted to assess joint action components.
  • The spatial numerical association of response codes (SNARC) effect was utilized.

Related Experiment Videos

  • Symbolic numerical stimuli were mapped onto a mental number line to test co-representation.

    • Main Results:

    • A joint SNARC effect was demonstrated, confirming functional equivalence in action representation.
    • Numerical stimuli activated co-represented actions similarly to spatial stimuli.
    • Evidence supports the generalization of previous co-representation findings.

    Conclusions:

    • The mirror system underpins the ability to represent others' potential actions.
    • This co-representation mechanism is crucial for shared intentionality and communication.
    • Findings extend our understanding of how the brain facilitates social interaction and joint action.
