SPEECH AND LANGUAGE
NEWS
FEBRUARY 2008
A
paper written by Carol Connor, a researcher with the Florida Center for Reading
Research, and her colleagues from Florida State University and the University
of Michigan, report that individualized reading instruction based on each
student’s individualized needs are more effective than any one “best” reading
method. You can fine the article
in the January 2007 issue of Science.
Variety of factors:
Biological
issues present t conception or occurring during gestation.
Various
degrees of difficulty in dev. speech are associated with MR, CP, Autism, and
Developmental apraxia of speech.
Speech
Impairments also may be associated with factors that are acquired after birth
such as Amyotrophic Lateral Sclerosis, Multiple sclerosis, Traumatic Brain
Injury, Stroke, and Spinal Cord Injury.
In
the case of Autism, we do not know how the disorder is specifically related to
difficulties in acquiring speech—that is, we do not yet understand what parts
of the brain are influenced in such a way as to affect the dev. of speech. In general, there does not appear to be
any distinct problem with the structural aspects of speech production (an
intact tongue, lips, palate. etc.) or the motor aspects (moving the tongue,
lips, jaw, etc.) We do not understand why some rapidly dev. speech (including
speech with unusual features such as echolalia) while others remain mute(do not
use speech to effectively comm.)
How
prevalent? Recent estimates
indicate that approx. 1 in100 individuals will need significant assistance in
acquiring effective comm.. strategies that do not depend on speech.
Before
relatively effective early intervention programs were designed, it was widely
estimated that half of all children with autism remained mute.
With
aggressive early intervention, the rate of mutism drops substantially to 15% or
less depending upon the characteristics of the children beginning the intervention.
