Developing preliminary speech of Autism
Most of early intervention parent and some of Autistic adolescents think that development of speech is an escape route from Autism Spectrum Disorder. They spoil their young parenthood after speech therapist, who usually works to develop articulation. If the autistic child has any preliminary articulation, speech therapist continues over language development.
But I have an overview of the protocol.
Brauka is the region in the frontal lobe of the dormant hemisphere usually left of the hominid brain with functions linked to speech production. Functional MRI studies have also identified inactivation patterns in Broca's area associated with various language tasks.
There is differences between human language and systems of communication existing among animals (particularly other primates).
Origins of language probably relate closely to the origins of modern human behavior.
"I cannot doubt that language owes its origin to the imitation and modification, aided by signs and gestures, of various natural sounds, the voices of other animals, and man's own instinctive cries "
— Charles Darwin,
Broca's area is active when people are observing others engaged in meaningful action.
Broca's area was involved in translating gestures into abstract ideas by interpreting the movements of others as meaningful action with an intelligent purpose.
There is an observation that frontal language areas are activated when people observe Hand Shadows and it has further evidence that human language may have evolved from existing neural substrates that evolved for the purpose of gesture recognition.
So the precursors to human language are present at both the behavioral and neuron anatomical levels.
Therefore we conclude that the correlation between damage to certain specific brain areas (usually in the left hemisphere) and the development of specific types of speech loss related to autism makes it possible.
