A new research study has determined that a gene linked with physical pain sensitivity is also associated with social pain sensitivity. According to UCLA psychologists this is the first time the relationship has been established.
Their study indicates that variation in the mu-opioid receptor gene (OPRM1), often associated with physical pain, is related to how much social pain a person feels in response to social rejection.
People with a rare form of the gene are more sensitive to rejection and experience more brain evidence of distress in response to rejection than those with the more common form.
The research was published in the online edition of Proceedings of the National Academy of Sciences and will appear in the print version in the coming weeks.
The findings give weight to the common notion that rejection
