There are some special properties of human language
Communicative and informative signals
May be intentional and
unintentional
Your accent,
movements and
dressing code, among
other elements
communicate things
about you
unintentionally
Words or
sounds
communicate
intentionally
Displacement
Is the property of
human language that
allows language users
to talk about things,
events or places whose
existence we cannot
be even sure
We can use
language to
talk about
present, past
and future
Animal
communication
seems to be used
exclusively in the
moment.
Animal
communication
lacks of this
property
Arbitrariness
In human language
there is no 'natural'
connection between a
linguistic form and its
meaning
Animals seem to
have a finite set of
signals to
communicate, and
there is non
arbitrariness in it
Productivity
Is the property
humans have of
continually
creating new
expressions and
utterances.
This property
is described
also as
creativity or
open-endedness
Animals have
limited signals
ato communicate
which is called
fixed reference
that cannot be
manipulated
Cultural transmission
Humand acquire
language in a
culture with other
speakers and not
from parental
genes. It is passed
on from one
generation to
another
Animal are born
with a set of
pecific signals
that are
produced
instinctively as
their
communication
pattern
Chimpanzees and language
Non-human primates don't have a
physically structured vocal tract suitable
for articulating the sounds used in
speed
Apes and gorillas can communicate
with a wide range of vocal calls, but
they cannot make human speech
sounds
Several studies
have been
performed with
cimps
Gua (1930s)
Was raised as a
child. Was able to
understand about
a hundred words,
but didn't say any
of them.
Viki (1940s)
Eventually
produced some
words poorly
articulated
Washoe
In a period of three
and a half years
came to use signs
for more than a
hundred word, even
showed the ability
to combine them to
produce 'sentences'.
Sarah
Was trained to
use a set of
plastic shapes for
communicating
with humans.
Sarah was
capable of
producing
'sentenes' and to
understand
complex
structures.
Lana
Was trained
to learn a
set of
symbols on
a large
keyboard
linked to a
computer
Based on studies it is argued that
chimpanzees simply produce signs in
response to the demands of people and tend
to repeat the signs those people use, like
performing sophisticated tricks in order to
get rewards, not really communnicating or
producing language.
