Sensory Impairments
Hearing Impairment
Visual Impairment
Hearing Impairment





Prelingual deafness
 onset before language development
Postlingual deafness
 onset after language development
Conductive loss
 air or bone conduction disruption
Sensory loss
 interference in inner ear or neural pathways
Cochlea
 primary organ of hearing
 connects inner ear pathways to brain pathways
Levels of hearing loss

Hard of hearing



35-70 decibel loss
Educationally - can
learn language
through hearing
Deaf


greater than 70
decibel loss
Educationally cannot learn
language through
hearing
Visual Impairment



Visual functioning
 use of residual vision
Low vision
 significant visual impairment but
usable vision
Partially sighted
 20/70 - 20/200 vision
 Educationally - requires large
print
Visual Impairments

Blind
 20/200 or less
vision
 20 degrees or
less field of
vision
 Educationally
- requires
Braille
Developmental maturation
Cephalo-caudal (head to tail)
 Proximal-to-distal (central to peripheral)
 Gross-to-fine
 Physiological flexion (general bending at
joints) to antigravity control
 Stability to mobility to skilled movement
