Research suggests that maternal care instinct may mediate the effect of oxytocin receptor gene on empathy, revealing the mechanism behind empathy emergence when witnessing another person in pain.
To feel other's pain would elicit empathy. Some theorists hypothesized that observing other's pain may activate the primary emotion of maternal care instinct, which may function as a precursor of empathy. The maternal care instinct and empathy share the same genetic background and neuroendocrine underpinnings. An extensive body of research has shown that maternal behaviors relate to the oxytocinergic system, which has a strong influence on empathy. These studies suggest that the maternal care instinct may mediate the effect of oxytocin receptor gene (OXTR) on empathy. To provide evidence for this mediation, we used the subscale of CARE in Affective Neuroscience Personality Scales (ANPS) to measure the maternal care instinct and tested twoOXTRsingle-nucleotide polymorphisms (SNPs), rs53576 and rs13316193, in 880 high school participants (588 females, 292 males;M-age = 16.51 years old, SD = 0.65). Results showed that the genotype of rs13316193 was indirectly associated with empathy via CARE, suggesting a mediating role of CARE in the pathway fromOXTRto empathy. These findings may contribute to an understanding of how empathy emerges when one witnesses another person in pain.
