So we’re seen WHAT we are working towards in terms of what a secure base relationship looks like and the benefits it has. Before we continue to see HOW we can develop such a relationship with the child we are working with, let’s first explore HOW this attachment is built in the brain. Understanding this will hopefully clarify to you that this isn’t just useless “fluffy” talk; in fact, there are real, measurable, and tanglible ways that a secure base relationship affects the brain.
Let’s see how…
Nature and Nurture Inform Each Other
“Everything that is before birth is genetic and everything after birth is nature”: this is false.
Genes continue to be programmed after birth, so nature and nuture inform each other. What happens in the environment turns genes on or off, and genes influence the environment itself.
Parent Behaviour Informs Brain Development
In order for parts of the limbic system to grow (those having to do with social and emotional functioning), certain experiences are needed, mainly from the attachment figure. If the experiences in this part of development (before 2 years of age) are positive, we can imagine that that child’s genes have a very high potential.
Note that the genes have a high “potential”, but they are not yet fully and completely programmed in a fixed manner.
Neurons that Fire Together, Wire Together & Those that Don’t, Die Together
The brain doesn’t keep growing and growing. The brain organizes and then disorganizes.
This means that the connections in hte brain that are sustained, used often, and maintained are the ones that grow stronger and stronger. This is how learning happens: At first you struggle to add numbers, but by doing school work and homework you are practicing the skill and the “addition” connections in your brain get stronger and stronger.
On the other hand, if you don’t practice addition enough, you “unlearn” what you had learned before. In this case, the connections that weren’t used weakened and died.
This is why strong social contact with attachment figures early on in life are crucial to build these strong “social and emotional” connections in the brain.
Brain Development in Early Childhood Informs Our Behaviour
Babies change their nuture seeking strategies to suit the particular emotional capabilities of their caregiver so that they get as much care as that particular caregiver can give them.
This happens at a time when the brain is going through a huge phase of development, and therefore, the connections that are built (and the patterns of behaviour that are established, such as strategies to seek care from an attachment figure) can influence the pattern for making and maintaining relationships in the future for the child.
Empathy
When the caregiver responds to the baby appropriately, he/she begins to gain a sense of high self-esteem, leading them to have the capability of empathising with others. The child also has a positive model of what to expect from another person in a relationship, which is essential for long-term friendships and other relationships.
