Imaging the intentional stance in a competitive game

Area of Science:

• Neuroscience
• Cognitive Science
• Social Psychology

Background:

• The intentional stance involves interpreting entities as rational agents with beliefs and desires.
• This stance is a crucial component of mentalizing, a broader social cognitive function.
• Understanding the neural basis of the intentional stance is vital for social cognition research.

Purpose of the Study:

• To investigate the neural substrates of "on-line" mentalizing.
• To identify brain activity specifically linked to adopting an intentional stance.
• To differentiate intentional stance processing from other cognitive demands.

Main Methods:

• Positron Emission Tomography (PET) was used to measure brain activity.
• Volunteers played a computerized "stone, paper, scissors" game against a perceived human opponent or a computer.
• A paradigm with tight control over cognitive demands was employed.

Main Results:

• A single brain region, the anterior paracingulate cortex (bilaterally), showed increased activity when volunteers adopted the intentional stance.
• This region is known to be involved in previous mentalizing studies.
• This study provides the first specific link between anterior paracingulate cortex activity and the adoption of an intentional stance.

Conclusions:

• The anterior paracingulate cortex plays a specific role in adopting an intentional stance.
• This finding advances our understanding of the neural mechanisms underlying social cognition and prediction of behavior.
• Future research can further explore the precise functions of this region in complex social interactions.
