Lecture 16 Flashcards
(16 cards)
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
Brain weight triples in the first ____ months and by 10 years of age the brain is at ____% of its ultimate weight.
24 months; 95%
What part of the brain plays a role in regulation?
brainstem, cerebral cortex and reticular formation
What part of the brain plays a role in processing?
The posterior cortex
What part of the brain plays a role in formulation?
The frontal lobe
Most brain growth after birth is a result of what?
developing synaptic connections and myelination
In what order does myelination occur?
first in the primary cortex, then association cortex
What does myelination of axons allow for?
rapid transmission of neural info.
A lack of myelin maturation can lead to?
The development of language delays
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
Very young children may switch language dominance to the right hemisphere. T or F?
True
The period of time where substantial neuroplastic changes are possible is called the ?
critical period
*different portions of the cortex have different critical periods
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
In bilinguals there is a greater overlap of _______ ________ for language between L1 and L2 the earlier the L2 is learned.
Neural representation
There is a similar correlation between language impairments and _______ ____ in children as there is in adults.
Lesion Site
Neuroimaging studies suggest involvement of the ______ lobes and _____ ______ in children with ADHD.
Frontal; basal ganglia
