Culture modulates brain activity during empathy with anger.

Area of Science:

• Neuroscience
• Cross-cultural psychology
• Social cognition

Background:

• Cultures vary in valuing harmony, with interdependent cultures prioritizing it more than independent cultures.
• Anger, an emotion disrupting harmony, is perceived differently across cultures, influencing empathic responses.
• Understanding cultural variations in empathic processing of emotions like anger is crucial for cross-cultural communication.

Purpose of the Study:

• To investigate distinct brain activity patterns in interdependent (Chinese) and independent (German) cultures during empathic processing of angry faces.
• To explore the neural correlates underlying cultural differences in the perception and regulation of anger.
• To examine the relationship between cultural interdependence and brain responses during empathy tasks.

Main Methods:

• Functional magnetic resonance imaging (fMRI) was used to scan healthy Chinese and German adults.
• Participants performed an intentional empathy task involving familiar angry and neutral faces, alongside control and baseline conditions.
• Behavioral data on interdependence levels were collected and correlated with brain activity.

Main Results:

• Both Chinese and German subjects showed comparable brain activity in regions like the left inferior frontal cortex during empathy for anger.
• Chinese subjects exhibited stronger activation in the left dorsolateral prefrontal cortex when empathizing with familiar angry faces.
• German subjects showed greater activation in the right temporo-parietal junction and temporal gyri, and left middle insula for the same task, with these regions correlating with interdependence scores.

Conclusions:

• Enhanced emotion regulation in interdependent cultures during anger empathy is associated with left dorsolateral prefrontal cortex activity.
• Increased tolerance for anger expression in independent cultures is linked to heightened activity in the right temporo-parietal junction, temporal gyri, and left middle insula.
• Cultural dimensions of interdependence and independence shape distinct neural pathways for processing anger during empathy.
