Why do we talk?
Language
defines you as being human
We barely
notice we do it
From birth,
language is in our lives
Deb Roy – Massachusetts Institute Of Technology
Turned his
home into a lab and used his own son
Had to be
observed and heard 24 hours a day
‘The
Speech Home Project’ highlights that semantic awareness outstrips phonological
ability
Babbling
turns to words to single words which turns to the two word stage to more
complex grammatical structures
At 5
years old we know 5000 words, as adults we speak 15000 words a day
Noam Chomsky
Believed
we have an unconscious innate understanding
But we
also need to be exposed to language at an early age
Is it NATURE
or NURTURE?
‘Forbidden
Experiment’ – isolating a child in silence
Ofer
Tchernichovski
Found a
way to do the experiment
He used
birds that imitate their parents like babies and isolated the chicks
Faraneh Vargha-Khadem
Studied genes
in a family with speech difficulties
Found chromosome
7 found in each family member
Found
that it was broken
Named it
FOX-P-2
