Attention allocation in complementary joint action: How joint goals affect spatial orienting.

Area of Science:

• Cognitive Psychology
• Social Psychology
• Neuroscience

Background:

• Joint actions involve complementary actions and shared spatial focus.
• Social inhibition of return (IOR) describes slower responses to previously attended locations.
• Achieving joint goals may necessitate attending to a co-actor's previous actions, potentially conflicting with social IOR.

Purpose of the Study:

• To investigate if the goal of joint actions modulates social inhibition of return (IOR).
• To determine if pursuing a shared objective alters attentional orienting towards a co-actor's actions.
• To extend research on perception-action effects by examining the role of joint goals.

Main Methods:

• Participants performed cued location responses with a virtual co-actor.
• Experiments involved either individual goals or joint goals requiring complementary actions.
• Social IOR was measured by comparing response times to previously acted-upon locations versus alternate locations.

Main Results:

• Social IOR was significantly modulated when participants and the co-actor pursued a joint goal.
• The presence of a shared objective altered the typical social inhibition of return effect.
• Attentional orienting was influenced by the social relationship and the shared goal between agents.

Conclusions:

• Attentional orienting during joint actions is affected by both spatial and social factors.
• Shared goals play a crucial role in modulating interpersonal perception-action effects.
• The way one agent's actions influence another's perception and action depends on shared intentionality.
