Pro-environmental and Prosocial Decisions Share Neural Correlates

Area of Science:

• Neuroscience
• Environmental Psychology
• Social Cognition

Background:

• Existing research indicates a correlation between pro-environmental choices and prosocial behavior.
• However, the underlying neural mechanisms common to both decision types remain largely unexplored.

Purpose of the Study:

• To investigate whether pro-environmental and prosocial decisions engage overlapping neural pathways.
• Specifically, to test if the temporoparietal junction (TPJ) is a shared neural correlate for these behaviors.
• To examine the TPJ's role in modulating the attitude-behavior gap in environmental decision-making.

Main Methods:

• Functional magnetic resonance imaging (fMRI) was employed on 35 healthy adult participants.
• Participants completed tasks involving pro-environmental decisions, prosocial decisions, and a control task for future-oriented decisions.

Main Results:

• Significant overlapping neural activation was observed between pro-environmental and prosocial decision-making in regions of the mentalizing network, including the TPJ.
• Increased TPJ activation was found to be associated with a reduced attitude-behavior gap, suggesting a moderating role.

Conclusions:

• Pro-environmental decision-making shares neural substrates with prosocial decision-making, particularly within the mentalizing network.
• The TPJ plays a crucial role in aligning environmental attitudes with actual behaviors, potentially by integrating social and future-oriented information.
