Andy’s Quick Hits (235): Unpredictable Parents Disrupt Brain Circuitry in Children
Intuitively we all know that good parenting is essential to kids’ healthy development. We all agree on that.
But as soon as we try to define what good parenting is we then enter into controversial territory with diverging opinions, multiple lines of differing research, and some of the world’s best-selling books. In the USA the legendary Dr Spock’s “The Common Sense Book of Child and Childcare” still ranks as one of the best-selling books of all time.
However, research has slowly built up a solid base of what it needs to bring up children. The “all you need is love” philosophy proving to be extremely robust. Research into various animal models, show that offspring who receive more care developed better, but also research into the brain shows that the brain responds by building more connections, and having healthier, or better formed, brain cell populations, and stronger brain circuits in critical areas.
I have written about the dramatic impacts on upbringing, particularly obvious when conditions are dire. So, the research is painting a clearer picture here. But this latest piece of research out gives us a clue to something else that seems to be critical — and many may already have worked out and intuited.
What is this?
It is about predictability or consistency of parenting. And in particular the focus on this study was on how this impacts brain circuits.
What did they find?
The researchers at the University of California Irvine compared brains of offspring in mice that were put into maternal care situations which had the same level of care but in one group the maternal behaviour was less predictable.
They found that this impacted the maturing brain at critical nodes impacting connectivity in key regulatory and emotional networks. This suggests that unpredictable parenting is associated with deficits in emotional control and behaviours. That’s really important to know.
This shows that care itself is not enough. Love and care is very good, but predictably seems to be something that is essential for healthy brain development. Something that is present in our SCOAP model with the “O” standing for Orientation which includes having clear understanding of the world around us and this is clearly strongly defined in the developing brain by predictability of parents.
But I wouldn’t put this down to just parenting — predictability and consistency in behaviour is just as important in business as it is parenting. But if you brain hasn’t developed healthily in the first place, then it may be too late.
