How does monetary loss empathy modulate generosity in economic sharing behavior? An ERPs study.

Area of Science:

• Neuroscience
• Social Psychology
• Behavioral Economics

Background:

• Generosity in economic sharing and empathy for monetary loss decrease as social distance increases.
• The relationship between decaying monetary loss empathy and economic sharing generosity across social distances remains unclear.

Purpose of the Study:

• To investigate if decayed monetary loss empathy influences generosity in economic sharing behavior across varying social distances.
• To provide electrophysiological evidence for the link between empathy decay and generosity decay.

Main Methods:

• Two experiments were conducted involving participants in observation and execution groups.
• Monetary loss empathy was assessed using electrophysiological measures (d-FRN).
• Generosity in economic sharing behavior was quantified using the log-transformed k value (ln(k)).

Main Results:

• In the observation group, a negative correlation was found between ln(k) and the distinction of d-FRN between friends and strangers.
• In the execution group, no significant correlation was observed between ln(k) and the distinction of d-FRN between self and strangers.
• Results indicate that decayed generosity across social distances can be modulated by decayed monetary loss empathy.

Conclusions:

• Decayed monetary loss empathy significantly modulates generosity in economic sharing behavior across different social distances.
• The study provides electrophysiological evidence supporting the link between empathy decay and generosity decay.
• Findings deepen the understanding of social distance's impact on prosocial behavior and empathy.
