Question 1

Name at least three of the primary types of dangers to children aged 2 to 6 years. Explain the three levels of injury prevention and provide an example of each.

Accepted Answer

Preschoolers are most likely to be injured by 1) autos, 2) drowning, 3) poisoning, and 4) falling. They are at risk because of their poor impulse control and their inability to assess risk due to their immature prefrontal cortex.
Primary prevention makes a safer situation to reduce the likelihood of injury, such as using streetlights instead of stop signs.
Secondary prevention reduces risk in high-risk situations, such as adding flashing lights at crosswalks.
Tertiary prevention provides a remedy after an injury has occurred, such as quick triage in the emergency room.

Question 2

Describe at least four ways in which the growth in the corpus callosum improves children's capabilities.

Accepted Answer

The corpus callosum connects the two hemispheres of the brain through a band of nerve fibers. This connection offers 1) greater eye-hand coordination and 2) better coordination of the brain and body. This helps 3) improve motor abilities and 4) determines handedness. It also offers children 5) the ability to think before they act, thus 6) reducing the number of childhood accidents they suffer.

Question 3

Explain the roles of the prefrontal cortex and limbic system in early childhood. What are their functions? How do they differ? What changes occur in a child's behavior as a result of the maturing limbic system and prefrontal cortex?

Accepted Answer

The prefrontal cortex is the executive of the brain, essential to planning, analyzing, and complex thought. The limbic system controls the expression and regulation of emotions and processes memory. As the prefrontal cortex matures, the child's ability to plan increases and impulsiveness decreases. As the limbic system matures, memory improves while nightmares and irrational fears decrease.
