A soothing voice can change your hormones…but a text message won’t

It ’s not always easy to distinguish between human social interaction and the complex chemical interactions that corroborate them . Just hear a calming , intimate voice can alter a person ’s hormones in a beneficial way … and technology just start out in the way .

That ’s the determination of biological anthropologist Leslie Seltzer of the University of Wisconsin . She designed an experimentation in which untried missy age 7 to 12 were first face wit a nerve-wracking laboratory task , and then were allowed to have reassurance from their mothers . on the button how the mother pass along varied – some were able to verbalise face - to - face , others talked on the speech sound , and still others could only send a text . Some of the girls had no striking with their mother at all .

Seltzer and her team found that daughters who could get a line their mother – whether it was in someone or over the phone – usher light drops in their Hydrocortone stage and a release of oxytocin . Cortisol is a endocrine unremarkably link up with stress , while oxytocin is the so - called “ sexual love hormone ” ( a term not withoutits disputation ) . Basically , on a hormonal level , the presence of a mother ’s voice allowed the missy to straight off sense better .

As for the girls who could only receive a text edition message , they showed no release of oxytocin , and their hydrocortisone levels remained so mellow that it was if they had never communicate with their female parent at all . There are a couple potential grounds for this . One is the evolutionary rationality – language has a long history in our coinage , and it do gumption that a mother ’s voice would be able to comfort their children , right down to a chemical layer .

Of course , there is another possible action – the mother might just be take a crap at text messaging . While the mothers were told to be as reassuring and know as they could be in their texts , it ’s conceivable that they lacked the same intuition with text messaging that they do with address , and that had something to do with it . It would be interesting to try this experimentation again in , say , 2031 , when the mother involved would presumptively have grow up using text messaging from a immature age than mothers today . Even so , I would n’t wager against a female parent ’s voice when it comes time for a replay .
