When does a child become self-aware? The answer will surprise you.
The phrase “use it or lose it” is often employed in reference to the diminishing cognitive function associated with aging. But it’s just as apt when it comes to early brain development.
During this time, your child’s brain is rapidly forming new synaptic connections between nerve cells, establishing a dense messaging network that allows for complex mental processing and motor function. The more these neural connections are stimulated, the stronger they become, while less-used neural pathways weaken and die off. That’s why providing an enriching environment with regular verbal and physical stimulation is so important to your child. Here’s a look at some of the ways his brain (and your encouragement) is fueling all sorts of new skills right now.
At this point in your child’s growth, myelination (a process in which the nerve cells establish a thick protective coating that helps speed up brain signals) is in full swing. One area where the progress of myelination is most apparent is in your child’s increasing memory. Up to now, your child has been able to recognize familiar objects—a type of memory that involves only one region of the brain: the hippocampus. But after his first birthday, thanks to development in the cerebral cortex, he becomes able to consciously recall information at will. Eventually, synaptic connections linking the hippocampus and various regions of the cerebral cortex will form and strengthen, allowing for more complex types of memory that involve multiple regions of the brain.
Development of the cerebral cortex at this age also allows for the emergence of higher-order cognitive abilities, including self-awareness. Starting around 15 months, your toddler will begin to recognize that the face he sees in the mirror is his own.
By the end of the first year, your toddler’s cerebellum—the part of the brain responsible for coordination and balance—has tripled in size, which is reflected in the enormous leaps in gross motor skills he’s making. You’ll also see your child’s newfound coordination on display in his constant grabbing, dropping, and throwing of toys.
The areas of the brain associated with language have more synaptic connections than any other part of the brain during this period, causing a leap in language abilities known as the vocabulary explosion. Remarkably, between your child’s first and second birthdays, his vocabulary will quadruple. Although the parts of the cerebral cortex known as the temporal lobes (which are located on either side of the brain) are most specifically involved in hearing and language, the frontal lobes (which are associated with memory) also play an important role in learning and producing words. By listening and trying to understand your speech, your toddler gives these neural pathways a healthy workout, which stimulates even more advances.
In the months after your toddler’s first birthday, you’ll notice him becoming more engaged with the world around him. The fact that the limbic system develops before the cerebral cortex figures largely in your emotional experiences. At 12 to 18 months, your child can process and store emotional events but doesn’t yet have the language and memory skills to consciously consider and express his emotions verbally. At this age, your also interacts with you in more emotional ways; he has learned that smiling, laughing, squealing, and talking all elicit certain reactions from you. This development is fueled by maturation of the temporal lobes, which are associated with the ability to read facial cues, interpret emotional signals, and exhibit other aspects of social understanding.
