A research paper defense presentation about how children with Down syndrome develop spoken language.

1. Language
Development of
Children with Down
Syndrome
Language development
of children with Down
syndrome is different
from typically

2. What is Down
Syndrome?
• Also known as Trisomy 21.
• A chromosomal condition caused the presence of an extra
21st chromosome.
• It is named after John Langdon Down.
• A cause of Mental retardation.

3. Mental Retardation
• Below-average intellectual functioning.
Mild MR - IQ of 50 – 55
Moderate MR - IQ of 35-40 to 50-55
Severe MR - IQ of 20-25 to 35-40
Profound - IQ of below 20 or 25

4. CONTINUATION
• Individuals with Down syndrome usually have low
intelligence,
• IQ of children with Down syndrome is around 50.
(which then explains that a child with DS is also MRd)
• Was then called MONGOLOIDS.
• (symptoms)

5. Aspects of Language
• Phonology (utters)
• Semantics (understand & comprehend)
• Social-Communication (communicate with others)

6. Language development of
children with Down
syndrome is different
from typically developing
children in the aspect of
phonology, semantics, and
social communicative
development.

7. Language development of
children with Down syndrome is
different from normally
developing children in the
aspect of phonology

8. • Babbling appears to be delayed by approximately two
months compared to typically developing children.
• There is a delay in the production of speech sounds
(compared to normally developing children)
• The difficulties in the formation of sounds occur in
children with Down syndrome than in normal
children.

9. Language development of children
with Down syndrome is different
from typically developing children
in the aspect of semantics

10. • Children with Down syndrome develop vocabularies
at the rate which is comparable to their mental age.
• Their vocabulary is usually lower than typical adult
levels.
• Children with Down syndrome at the age of 6 are
more than 3 years behind typically developing
children when it comes to lexical development.

11. Language development of children
with Down syndrome is different
from typically developing children
in the aspect of social
communicative development

12. • There is difference between the social
communicative development of children with Down
syndrome.
• Children with Down syndrome show delays in the
development of social communication.
• Children with Down syndrome are not good at
interacting with a person and doing other things
(playing with toy) at the same time.

13. CONCLUSION

14. There are delays in the language development
of children with Down syndrome compared
to children who are developing normally.
