Massage therapists often describe themselves as kind, caring and empathetic. New research indicates that the quality of empathy is linked to genetic variation.
University of Toronto investigators have discovered that a gene that influences empathy, parental sensitivity and sociability is so powerful that even strangers observing 20 seconds of silent video identified people with a particular genetic variation to be more caring and trusting, according to a press release.
In the study, 23 romantic couples were videotaped while one of the partners described a time of suffering in their lives. The other half of the couple and their physical, non-verbal reactions were the focal point of the study.
Groups of complete strangers viewed the videos. The observers were asked to rate the person on traits such as how kind, trustworthy, and caring they thought the person was, based on just 20 seconds of silent video.
“Our findings suggest even slight genetic variation may have tangible impact on people’s behavior, and that these behavioral differences are quickly noticed by others,” said Aleksandr Kogan, a postdoctoral fellow at the University of Toronto and the study’s lead author.
Oxytocin has already been significantly linked with social affiliation and reduction in stress. It is a peptide made in the hypothalamus and has targets all over the body and the brain. It is best known for its role in female reproduction and is associated with social recognition, pair bonding, dampening negative emotional responses, trust and love.
Out of the 10 people who were marked by the neutral observer as “most prosocial, six carried the GG genotype associated with the oxytocin receptor; of the 10 people who were marked as “least trusted,” nine were carriers of the A version of the gene. The people carrying an A version of the gene were viewed as less kind, trustworthy and caring toward their partners in the video.
