least plasticity:
Early Childhood, Adulthood, Late Childhood, Adolescence Answer:
Early Childhood, Late Childhood, Adolescence, Adulthood
◉ 2. The age at which a human brain has the most connections
between its neuron is: Answer: 3
◉ 2. How do experiences shape the developing brain? Answer: They
influence which neural connections are strengthened and which are
pruned away.

The interaction between genes and environmental influences.
, ◉ 3. Which of the following is an example of an epigenetic effect?
Answer: An environmental factor that modifies the area surrounding
a gene such that its expression decreases.

the quality of maternal care in rat offspring? Answer: The
glucocorticoid receptor gene
◉ 3. What happens to the stress response system when the
glucocorticoid receptor gene is epigenetically modified such that it is
less active and produces fewer receptors? Answer: The stress
response increases

modification to the glucocorticoid receptor gene in victims of
suicide? Answer: Childhood Maltreatment
