2. Autonomic
The part of the nervous system that
automatically controls the body
functions necessary for life, and
thus areas of the brain not directly
responsible for language and
speech.
4. Iconic
One-to-one relationship between signs and
their referents (e.g. lowering the pitch of your
voice on ‘deep’ when you describe someone
by saying he ‘speaks in deep voice’).
For example, the hungrier a baby becomes,
the louder and the longer the crying will be.
6. Sings which have a random and
arbitary relationship with their
referents (e.g. ‘sun’ is a small word
but a tiny object; micro-organism is
a large word but a tiny object.
