I've got your number: Spontaneous perspective-taking in an interactive task.

Area of Science:

• Cognitive Psychology
• Social Cognition
• Human-Computer Interaction

Background:

• Considering others' perspectives typically requires conscious effort.
• Joint action paradigms demonstrate social context influences cognitive processing.
• The role of implicit perspective-taking in collaborative tasks is under investigation.

Purpose of the Study:

• To investigate whether individuals implicitly represent their partner's viewpoint in a collaborative task.
• To determine the conditions under which this implicit perspective-taking occurs.

Main Methods:

• Participants engaged in a number magnitude judgment task, playing alone or with a partner.
• Performance was compared when partners shared or differed in their visual representation of the stimulus.
• Two further experiments manipulated partner involvement and attentional focus.

Main Results:

• Team play improved performance when partners shared the same visual interpretation of numbers (e.g., both seeing '8').
• Performance benefits were contingent on prior observation of the partner's involvement in the task.
• The specific stimulus feature attended to by the partner did not need to match the feature judged by the participant.

Conclusions:

• Individuals implicitly incorporate a partner's perspective during joint action, even without explicit instruction.
• This effect is modulated by perceived partner engagement and shared context.
• Findings suggest a more automatic social cognitive mechanism operating in collaborative settings.
