Executive functions and self-regulation typically develop and mature over a fairly long period of time. We see the infant sucking his fingers and thumb to regulate and soothe himself and that’s just the beginning.

Developing and refining self-regulation takes place over at least the first two decades of life. Each of the five key executive functions develops at different paces; some maturing earlier, some later.

Check out the diagram below. It shows that self-regulation starts developing from birth and doesn’t reach a mature level until at least the mid-twenties. That’s a long time but there are a lot of things going on.

Preschoolers show an enormous surge in their abilities to control their bodies. Regulating their emotions also matures quite a bit. Attention skills become less scattered and children can pay attention to things for longer periods of time. In the later preschool years, cognitive self-regulation improves. Children are better able to plan and organize themselves and things they want to do. Their working memory improves and they’re checking how they do. Their improved cognitive flexibility means that they can change plans and approaches to things more easier. One really important change in the later preschool years is the emergence of metacognitive awareness. That is, children become aware of their thinking, things that help them remember, and things that make it harder to learn.

All three areas of self-regulation (behavioral, cognitive and emotional) continuing improving during the school years. There’s a small dip during the teen years – ask any parent of a teenager what that’s about –  but it’s followed by continuing refinement.

After the mid-30s, self-regulation starts a decline. Those readers who are seniors will appreciate the changes in working memory and attention – “I’m in the kitchen, what was it I was going to do?”

Self-regulation develops over at least the first two decades of life. This long period of development means two main things: (1) we have a wide window of time to help our children develop and improve their self-regulation, and (2) we shouldn’t expect self-regulation to appear overnight.

Our brains are plastic in the sense that they can change and mold to new experiences. New nerve pathways are developed when we learn and practice new things. Keep in mind that learning to self-regulate takes time and daily practice. This is especially true for children who need to un-learn old ways of doing things and develop new approaches.
