Study shows that having a daughter can change a man's brain in a special way

There is no denying that having children changes all of us in many (many) ways. 

I mean; who knew you could survive on so little sleep, for instance? Or that you were able to wipe up vomit (so much vomit!) without actually starting to wretch yourself? I constantly marvel at how different post-motherhood me is to pre-motherhood me.

And guess what; never mind just us mums, parenthood changes dads too. In fact, it might change them more than we realise, according to recent research.

In a US study, researchers actually found that dads brains change more when they parent a girl – and discovered that fathers have different brain responses when they interact with their toddler daughters than they do when they play with their toddler sons.

Interestingly, the study, which was published in the American Psychological Association’s journal Behavioral Neuroscience, found that dads with girls tend to be more present and responsive to their daughters' needs than dads of toddler sons. As well as this, men with daughters also sang more often to their girls, talked more openly about their emotions and used more analytical words such as “all,” “below” and “much.”

In comparison, dads who have young boys are more inclined to take part in rough-and-tumble play and use words that are more sports- or achievement-related, such as “proud,” “win” and “top.”

Jennifer Mascaro, one of the lead researchers from Emory University and the University of Arizona, says her team speculated that the differences in interactions may be because dads accept girls’ feelings more easily than boys. “If the child cries out or asks for dad, fathers of daughters responded to that more than did fathers of sons,” Mascaro reveals.

As well as this, the changes to fathers' brains are actually so vast, they are detectable in MRI scans, as Mascaro and her team found when they used these to measure the participating fathers’ brains.

And according to the results – fascinatingly – dads of girls showed a more robust response to their daughters' happy facial expressions in the area of the brain that controls visual processing, reward, emotion regulation and face processing than dads with sons.

And this, according to the researchers, can to an extent explain why girls learn to be more empathetic than boys – as they have parents – dads – who are more attentive to their needs and open with their emotions.

Mascaro thinks there is a lesson in all of this for dads of boys – who, even without being aware of it, could be less attentive to the emotional needs of their sons.

“The fact that fathers may actually be less attentive to the emotional needs of boys, perhaps despite their best intentions, is important to recognise,” she says. “We should be aware of how unconscious notions of gender can play into the way we treat even very young children.”
