1

The course of speech and language development is related to _______ and an index of _______ is the change in gross brain weight with age.

cerebral maturation; neurologic development

2

Brain weight triples in the first ____ months and by 10 years of age the brain is at ____% of its ultimate weight.

24 months; 95%

3

What part of the brain plays a role in regulation?

brainstem, cerebral cortex and reticular formation

4

What part of the brain plays a role in processing?

The posterior cortex

5

What part of the brain plays a role in formulation?

The frontal lobe

6

Most brain growth after birth is a result of what?

developing synaptic connections and myelination

7

In what order does myelination occur?

first in the primary cortex, then association cortex

8

What does myelination of axons allow for?

rapid transmission of neural info.

9

A lack of myelin maturation can lead to?

The development of language delays

10

Cerebral plasticity allows for children with acute brain damage to have greater degrees of recovery than adults with similar kinds of damage. T or F?

True

11

Very young children may switch language dominance to the right hemisphere. T or F?

True

12

The period of time where substantial neuroplastic changes are possible is called the ?

critical period

*different portions of the cortex have different critical periods

13

What has been used to explain why language develops in the left hemisphere for most individuals?

There are structural differences between the left and right hemisphere

14

In bilinguals there is a greater overlap of _______ ________ for language between L1 and L2 the earlier the L2 is learned.

Neural representation

15

There is a similar correlation between language impairments and _______ ____ in children as there is in adults.
