Language Impairments:
Recap…
1. Language is lateralized: it is largely associated with the left hemisphere of the brain.
2. Language is modular: it is largely independent from other cognitive systems with which it
interacts.
Acquired vs. innate impairment
• Brain-damage causes a loss in language ability • Boa’s aphasia• Weike’s aphasia
• What can we learn about modularity and the autonomy of language from children who had
difficulties acquiring language?
Specific language impairment
• Some children have difficulties in acquiring language or are much slower than the average
child.
- They show no other cognitive deficits, they are not autistic or retarded, and they have no
perceptual problems.

• Such children are suffering from specific language impairment (SLI) - Language specific
deficit- Typically diagnosed between ages 3 and 8.- Impairment persists into adulthood
SLI is language specific
• Children with SLI lag behind in production and comprehension, but not other areas of
development
• SLI need not accompany problems with - hearing
- social abilities- general intelligence- obvious anatomical abnormalities
SLI delays onset of language
• SLI delays in language abilities• All individuals with SLI ee late talkes
- At age two, may produce first words- At age three, they may talk, but can't be understood -
Struggle to learn new words- Struggle to make coherent conversation
• Oly aout 25% of late talkes ae diagosed ith “LI
Grammatical characteristics of SLI
• Problems with morphology and syntax• Typical errors of English speakers with SLI
