The default mode network (DMN) is involved in understanding others across emotion perception, empathy, theory of mind, and morality. The medial prefrontal cortex (MPFC) plays a key role, with its subregions contributing differently: the ventral MPFC in the medial temporal lobe subsystem connects with emotion regions for emotional engagement; the anterior MPFC in cortical midline structures helps distinguish self from others; and the dorsal MPFC subsystem connects with the temporo-parietal junction for understanding others' mental states. As social behaviors become more complex, frontal regions involved are located higher, reflecting a shift from automatic to cognitive processing. Posterior cingulate cortex connectivity also changes. The DMN is indispensable for social understanding.

A randomized controlled trial of 92 Chinese police officers found that a 6-week program of daily 10-minute loving-kindness meditation guided by a short video app improved public service motivation, conflict resolution skills, and communication skills, but did not significantly enhance mindfulness. The intervention used a waitlist control group and validated scales. The results suggest that brief, digitally delivered compassion-focused meditation can be integrated into police training to strengthen prosocial motivation, de-escalation abilities, and public communication, potentially improving police-community interactions.

An 8-week video-guided mindfulness meditation program, delivered via short video apps, significantly reduced communication anxiety, post-traumatic stress symptoms, anger management difficulties, and mood disorders among police officers. In a randomized controlled trial with 92 full-time officers in China, those who completed daily 10-15 minute sessions showed greater improvements on validated measures compared to a control group. The findings suggest that digital mindfulness interventions can be an accessible tool for supporting mental well-being in law enforcement personnel.

Loving-kindness meditation (LKM) improved trust and sense of calling while reducing communication anxiety and defensive medicine practice among doctors. In a randomized trial with 94 doctors from a Chinese hospital, those who completed an 8-week LKM program showed significantly higher trust and calling, and significantly lower communication anxiety and defensive medicine practice, compared to a waitlist control group. The control group showed no changes. The findings suggest LKM may help reduce defensive medicine practice by fostering positive psychological states.
