Question

1. much learning comes from repetition. how does the development of connections in the brain explain why repetition strengthens synapses between neurons involved in a particular process.
2. what role does myelin play in the timing of childrens learning?
3. choose one of the rules to build a brain by. explain what it means and give an example of a caregiver can help a child by putting this rule in practice.
4. what is shaken baby syndrome? what causes it?

Explanation:

1. Repeated neural - firing during learning strengthens synapses between neurons involved in a particular process. When a child repeatedly practices a skill like tying shoelaces, the synapses related to the motor and cognitive functions for this task are strengthened.
2. Myelin is a fatty substance that insulates nerve fibers. In children, as myelin develops, it allows electrical signals to travel faster along nerve fibers, improving the speed and efficiency of neural communication related to learning.
3. "Serve - and - return interactions" mean that caregivers respond to a child's actions or signals. For example, when a baby coos and the caregiver coos back, it helps build the baby's communication skills and brain connections related to social interaction.
4. Shaken baby syndrome is a serious injury to a baby caused by forcefully shaking an infant. It can cause brain damage, bleeding, and other life - threatening conditions. It is typically caused by frustration or anger on the part of a caregiver who shakes the baby inappropriately.

Answer:

1. Repeated neural - firing during learning strengthens synapses for the task - related neurons.
2. Myelin insulates nerve fibers, allowing faster electrical signal transmission for better learning - related neural communication.
3. "Serve - and - return interactions" involve caregiver responses to a child's actions, like responding to a baby's coos to build social skills.
4. Shaken baby syndrome is a serious infant injury from forceful shaking, caused by inappropriate caregiver behavior.
