- SLI is due to deficits in cognitive, auditory, perceptual, and intellectual functions that underlie language.

- due to cerebellar damage
Ataxic CP
Which type of CP?
-increased spasticity (increased tone, rigidity of muscles) as well as still, abrupt, jerky, slow movements
-Due to damage to motor cortex or direct motor pathway
Most common
Spastic CP
Which type of CP?
- slow writhing involuntary movements
- Damage to indirect motor pathways, especially basal ganglia
Atheoid CP
Hemiplegia
one side of body is paralyzed
Paraplegia
only legs and lower trunk are paralyzed
Monoplegia

Diplegia

expressive language delays
What is more critical to language development than ethnic background?

Prelinguistic Behavioral Deficiencies in infants and toddlers
- Difficulty establishing eye contact, mutual gaze and joint reference

- Reduced babbling, fewer consonants in babbling and less complex babbling.
