Q

How does the brain organize itself with regard to hearing sounds?

A

so that it only recognizes those spoken sounds that are part of the language regularly heard

17
Q

During what stage of childhood does the brain retain the ability to detect and re-learn old and new sounds?

A

early childhood

18
Q

At what age does the window for learning sounds close?

A

late childhood around approximately 10 years old

19
Q

Windows of opportunity for gross and fine motor development?

A
gross = pre-5yrs
fine = 0-9yrs
20

25
In adolescent brain development, decreases in gray matter in prefrontal regions of the brain are reflective of?
-reflective of synaptic pruning
26
_____ - the period during which major improvements in basic cognitive abilities and logical reasoning are seen, in part due to these very anatomical changes
pre-early/adolescence
27
Substantial changes in the density and distribution of ___ receptors in pathways that connect the limbic system are seen during adolescent brain development
dopamine
28
when does myelination start to occur?
during adolescent development and continues well into late adolescence and early adulthood
29
During adolescent brain development, where is there an increase in the strength of connections?
between the prefrontal cortex and the limbic system
30
The connections between the prefrontal cortex and the limbic system strengthen during adolescent brain development, what is this anatomical change especially important?
especially important for emotion regulation
31
The middle adolescent brain stem is still immature in the systems important for self-regulation. What does this mean?
behaviours seen among this age category are more risky and reckless
32
Adolescents mature ____ before they mature _____ or ____
intellectually; socially or emotionally
33
When does the corpus callosum link between hemispheres become advanced?
fairly advanced by age 5, but continues to develop until approx. 10 years
