The presentation introduces the concepts 'early' and 'intervention'. It lists the exact reasons why early intervention is considered key to successfully achieving age appropriate objectives for a child with hearing loss. It connects early intervention with critical period hypothesis and draws its relevance to frequently seen struggle for communication by the children with d/Deafness.

NEED FOR EARLY
INTERVENTION

2. DIFFERENCE BET IDENTIFICATION AND
INTERVENTION 9
1.From suspecting to diagnosing (labeling)
AND
2. Post diagnosis action points:
 Parent guidance / empowerment
 Aids and appliance (or training on alternate mode)
 Enrollment in program (parent/child)
 HACSE

3. How early is EARLY??? (pattern in developing
countries 8
 Screening- no later than one month of age.
 Those not passing screening -comprehensive
audiological evaluation no later than 3
months of age.
 Appropriate intervention no later than 6
months of age from health care and education
professionals with expertise in management of
CWHI.( JCIH 2007 position statement)

4. Where do we stand?

Average age of identification of hearing impairment
in 2006 was 23 months and Educational
intervention was 34.6 months.
( Sirur and Rangasayee 2009)
Study conducted in and around Mumbai.
What about other areas?

5. Why early? NEED 6
1. Biological reason
2. Rehabilitative reason (span of intervention)
3. Minimizing the impact (HL turning into HH)
4. National reasons (Active participants of national
growth v/s ‘burden’ on growth

6. Critical period hypothesis (CPH)for language
development 5
 Concept – biological / neurological readiness /
maturation to acquire a skill
 Present in all animals (geese)
 Different for different skills
 Learning after that period is effortful and not
impossible
 CPH (Critical Period Hypothesis) and deafness
HACSE

7. Understand the concept
Analogy of earthen pot and imprinting.
Learning AFTER critical period is difficult / slow and
NOT IMPOSSIBLE.
Critical period is of no use if no exposure is ensured.

8. Imprinting (Lorenz, 1935)
