How does Piaget's theory on linguistic development support the type and order of words a child uses?

Piaget's theory of the four cognitive processes supports the type and order of words a child uses, this links in to Katherine Nelson's research which showed that a child's first words could be split into four groups: naming, action, social and personal and describing and modifying. A child's first stage of language is naming concrete nouns; seeing what is in front of them and attaching a name to the object. Piaget describes this as the sensorimotor stage, as the child approaches the age of 2 and begins to recognise objects for their colour or shape. As time goes on, a child will begin to use "action" words, such as "more" or "whack", this helps them receive a response and a greater understanding of interaction and conversation.
