By 1962 Piaget had come to agree with Vygotsky. It was found that inner or egocentric speech differs
from speech for other since it does not have to satisfy the grammatical conventions or any pragmatic
rules. Inner speech is often abbreviated since it is concerned with the underlying meaning of speech
and is seldom concerned with the abstracts of expressing it to others in a comprehensible way. It is
interesting to note that as we become more familiar with others our communication becomes more
like inner speech since we may share common vocabulary and context. The more shared experiences
we have in common the less explicit our speech is required to be. Consequently such conversations
can become more like inner speech.
