How preschoolers and adults represent their joint action partner's behavior

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Social Cognition

Background:

• Turn-taking joint action requires understanding a partner's actions and intentions.
• Representing a partner's behavior can be based on action kinematics or action effects.
• Understanding how individuals, especially children, represent partner actions is key to social cognition.

Purpose of the Study:

• To investigate the cognitive mechanisms of turn-taking joint action in 42-month-old children and adults.
• To determine if participants represent partner actions via kinematics or action effects.
• To examine the influence of learned action-effect associations on joint action performance.

Main Methods:

• A virtual bear-dressing task involving button presses to achieve specific effects.
• Two tasks: Action-response (matching/opposing partner's button) and Action-effect (achieving the partner's goal).
• Manipulation of partner's action-effect associations in 50% of trials.

Main Results:

• Neither children nor adults were affected by the physical congruency of actions.
• Performance in the Action-effect task was impaired when the partner's action-effect association differed from the participant's.
• Children made more overt errors, while adults showed increased reaction times under these conditions.

Conclusions:

• Agents' encoding of partner actions is influenced by their own learned action-effect associations.
• Flexible cognitive control, still developing in young children, is necessary for effective perspective-taking in joint action.
• These findings highlight the role of learned associations in social cognition and the development of shared intentionality.
