Question: how early do you learn?
Even if we can’t remember things explicitly are we still influenced by those events?
Prenatal Experience
For the last few decades there is a lot happening in the womb. Your listening in on what you
learn out there (meaning the fetus is listening). You have a preference to listen to mother’s voice. They
will suck on the nipple that activates the mother’s voice. They remember the content of what they
heard when they were in the womb. When the mother reads the story, they can remember the words of
the story. Just reading around a story repeatedly the infants will remember. The way they test it is by
sucking. It assumes that they are attentive when they suck the nipple slowly, taking it slowly. If they are
sucking fast then they are not paying attention.
The infants will come out of that womb, they cry in the accent of their mother’s tongue. They’ll
come out crying like German or French people. There are unique signatures that can be linked to the
style of crying. A lot is happening. They also develop food preferences. It’s food taste and smell.
So it’s a lot happening in that early critical period. What’s kind of also going on is that some of
these experiences are having a lasting effect on our developmental and health outcome. There’s been
some theorizing over the last couple of decades of notions on biological vulnerability which were early
significances, prenatal programming.
There are mechanisms that we understand that contribute to the early biological vulnerability
and impact of their life span.
Early Learning to Health:
Increase diabetes; that was one important piece of evidence that supports the Barker hypothesis.
What happens to you in the womb affects your destiny.
The predictive power of birth weight applies to us all. It’s better to be a heavier baby than a light weight
baby. There was a destiny on the health of each and every one of us.
What’s true of health may extend to our personality.
How people react to things is a big component to what makes them unique.
Core features of temperament. The core is reactivity and recovery regulation.
That methodological detail making the mother not hear it, not everything has to be fed from the outside
through the mother.
