Response to Piaget's theory on linguistic development

Jean Piaget Himself

Piaget talks about how small babies communicate primarily through basic physical actions - they're figuring out how to move around which eventually leads to crawling and walking. 
- " In the process she learns how to imitate some of the sounds she hears her parents making and in what context those sounds should be made." - Although the child cannot yet say specific words, she understands (to an extent) the nature of the intonation of certain words and when they should be made. For example: 
Mum: "Are you hungry?" There is a lot of emphasis on the question to help baby understand and encourage a response. The baby would probably respond with a high-pitched joyous sound as if to say 'yes please!'. 
Piaget's theory supports this because of her ideas on basic understandings of context and when may be appropriate to do certain things.

After the Sensorimotor stage, at discussed above, the child moves on to the Preoperational stage. According to Piaget this begins at 2 years and lasts until 6 or 7 years of age.
- " The defining feature of this stage, in Piaget's view, is egocentricity. The child seems to talk constantly, but much of what he says does not need to be said out loud." - It is evident that labeling words are the most commonly used by young children as it's essential when getting a grasp on the very basics of language.

The Concrete Operational Stage begins at the age of 7
