Language
Disorder
- Developmental language disorder is the
most serious handicap of children with
autism
- Children with autism fail to orient
normally to some sounds, but are often
hyper-reactive to others.
- Children normally learn language "by
ear," but by adolescence the auditory
acuity for language is lost, and the ability
to learn a second language, without
accent, becomes difficult.
- Children with autism appear to begin life
with an impaired acuity for word and
syllable boundaries.
- Nuclei of the midbrain auditory pathway
are metabolically more active than any
other area of the brain, and may provide
a vigilance function for the brain as a
whole.
- Language may represent the pinnacle of
an information-seeking system that
evolved from a protective mechanism to
maintain surveillance of environmental
events.
