Describe changes in the brain during early childhood
Give examples of gross and fine motor skill development in early childhood
Brain Maturation
If you recall, the brain is about 75 percent of its adult weight by two years of age. By age 6, it is at 95 percent of its adult weight. The development of myelin (
myelination
) and the development of new synapses (through the process of synaptic pruning) continues to occur in the cortex and as it does we see a corresponding change in what the child is capable of doing. Remember that myelin is the coating around the axon that facilitates neural transmission.
Synaptic pruning
refers to the loss of synapses which are unused. As myelination and pruning increase during this stage of development, neural processes become quicker and more complex.
Greater development in the prefrontal cortex, the area of the brain behind the forehead that helps us to think, strategize, and control emotions, makes it increasingly possible to control emotional outbursts and to understand how to play games. Consider 4- or 5-year-old children and how they might approach a game of soccer. Chances are every move would be a response to the commands of a coach standing nearby calling out, “Run this way! Now, stop. Look at the ball. Kick the ball!” And when the child is not being told what to do, he or she is likely to be looking at the clover on the ground or a dog on the other side of the fence! Understanding the game, thinking ahead, and coordinating movement improves with practice and myelination. Demonstrating resilience and recovering from a loss, hopefully, does as well.
Growth in the hemispheres and corpus callosum
Between ages 3 and 6, the left hemisphere of the brain, which tends to lag behind in terms of activity during the first 3 years of life, increases inactivity, which correlates with the burst in language skills during this time period. Activity in the right hemisphere grows steadily throughout early childhood and is especially involved in tasks that require spatial skills such as recognizing shapes and patterns. Both sides of the brain work together, however, and there is no such thing as a person being either left-brained or right-brained. The corpus callosum, which connects the two hemispheres of the brain, undergoes a growth spurt between ages 3 and 6 as well resulting in improved coordination between right and left hemisphere tasks.
I once saw a 5-year-old hopping on one foot, rubbing his stomach and patting his head all at the same time. I asked him what he was doing and he replied, “My teacher said this would help my corpus callosum!” Apparently, his kindergarten teacher had explained the process!
Visual Pathways
Have you ever examined the drawings of young children? If you look closely, you can almost see the development of visual pathways reflected in the way these images change as pathways become more mature. Early scribbles and dots illustrate the use of simple motor skills. No real connection is made between an image being visualized and what is created on paper.
At age 3, the child begins to draw wispy creatures with heads and not much other detail. Gradually pictures begin to have more detail and incorporate more parts of the body. Arm buds become arms and faces take on noses, lips, and eventually eyelashes. Look for drawings that you or your child has created to see this fascinating trend. Here are some examples of pictures drawn by girls from ages 2 to 7 years.

are more exact movements of the hands and fingers and include the ability to reach and grasp an object. Early childhood is a time of development of both gross and fine motor skills.
Early childhood is a time when children are especially attracted to motion and song. Days are filled with moving, jumping, running, swinging and clapping, and every place becomes a playground. Even the booth at a restaurant affords the opportunity to slide around in the seat or disappear underneath and imagine being a sea creature in a cave! Of course, this can be frustrating to a caregiver, but it’s the business of early childhood. Children may frequently ask their caregivers to “look at me” while they hop or roll down a hill. Children’s songs are often accompanied by arm and leg movements or cues to turn around or move from left to right. Running, jumping, dancing movements, etc. all afford children the ability to improve their gross motor skills.
Fine motor skills are also being refined in activities such as pouring water into a container, drawing, coloring, and using scissors. Some children’s songs promote fine motor skills as well (have you ever heard of the song “itsy, bitsy, spider”?). Mastering the fine art of cutting one’s own fingernails or tying their shoes will take a lot of practice and maturation. Fine motor skills continue to develop in middle childhood, but for preschoolers, the type of play that deliberately involves these skills is emphasized.
Watch It

Historically, children have been thought of as innocent or incapable of sexual arousal (Aries, 1962). A more modern approach to sexuality suggests that the physical dimension of sexual arousal is present from birth. That said, it seems to be the case that the elements of seduction, power, love, or lust that are part of the adult meanings of sexuality are not present in sexual arousal at this stage. In contrast, sexuality begins in childhood as a response to physical states and sensation and cannot be interpreted as similar to that of adults in any way (Carroll, 2007).
Infancy
Boys and girls are capable of erections and vaginal lubrication even before birth (Martinson, 1981). Arousal can signal overall physical contentment and stimulation that accompanies feeding or warmth. Infants begin to explore their bodies and touch their genitals as soon as they have sufficient motor skills. This stimulation is for comfort or to relieve tension rather than to reach orgasm (Carroll, 2007).
Early Childhood
Self-stimulation is common in early childhood for both boys and girls. Curiosity about the body and about others’ bodies is a natural part of early childhood as well. Consider this example. A mother is asked by her young daughter: “So it’s okay to see a boy’s privates as long as it’s the boy’s mother or a doctor?” The mother hesitates a bit and then responds, “Yes. I think that’s alright.” “Hmmm,” the girl begins, “When I grow up, I want to be a doctor!” Hopefully, this subject is approached in a way that teaches children to be safe and know what is appropriate without frightening them or causing shame.
As children grow, they are more likely to show their genitals to siblings or peers, and to take off their clothes and touch each other (Okami et al., 1997). Masturbation is common for both boys and girls. Boys are often shown by other boys how to masturbate, but girls tend to find out accidentally. Boys masturbate more often and touch themselves more openly than do girls (Schwartz, 1999).
Hopefully, parents respond to this without undue alarm and without making the children feel guilty about their bodies. Instead, messages about what is going on and the appropriate time and place for such activities help the child learn what is appropriate.
Parents should take the time to speak with their children about when it is appropriate for other people to see or touch them. Many experts suggest that this should occur as early as age 3, and of course the discussion should be appropriate for the child’s age. One way to help a young child understand inappropriate touching is to discuss “bathing suit areas.” Kids First, Inc. suggests discussing the following: “No one should touch you anywhere your bathing suit covers. No one should ask you to touch them somewhere that their bathing suit covers. No one should show you a part of their or someone else’s bodies that their bathing suit covers.” Further, instead of talking about good or bad touching, talk about safe and unsafe touching. This way children will not feel guilty later on when that sort of touching is appropriate in a relationship.
