People automatically create shared task representations, even without direct coordination. This social cognition influences individual performance when working alongside others, impacting reaction times.

Area of Science:

  • Cognitive Psychology
  • Social Psychology
  • Neuroscience

Background:

  • Individuals often unconsciously mimic and synchronize actions with others.
  • Previous research highlights behavioral adjustment in social contexts.

Purpose of the Study:

  • To investigate the formation of shared task representations between coactors.
  • To determine if these representations form even without explicit coordination needs.

Main Methods:

  • Pairs of participants completed a reaction time (RT) task concurrently.
  • Each participant responded to different dimensions of the same stimulus.
  • Performance was assessed with and without direct observation of the coactor.

Main Results:

Related Experiment Videos

  • Participant reaction times were slowed when both individuals had to respond.
  • This interference occurred even when participants could not see each other.
  • Performance was influenced by the coactor's task demands.

Conclusions:

  • Shared task representations form spontaneously in non-coordinative social settings.
  • These representations emerge from the conceptualization of the social situation.
  • This suggests an automatic social cognitive process influencing individual task performance.
