Piaget

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

Piaget's theory supports language development that they go through at different stages in their life from a very young age continuing on to young teenager, all four stages happen at a similar time for most children. The first stage is called sensorimotor stage. This stage last until the child is about two years old, and is mostly emphasised on movement. Small babies aren't yet away that they have control over their own bodies, they are unaware they they have the ability to complete small activities such as wiggling their fingers, waving their legs, crawl, and eventually nearer the end of the stage, bigger activities once they're aware of their ability to move their own limbs they may begin to walk with support, Piaget believed a similar process happens with the children language development. Learning sounds, experimenting, then with encouragement and support a children will begin to learn more complex language. 

The second stage is called the preoperational stage which begins at the age of two years and finishes nearer the age of six but some children vary until the age of seven. this stage is made up the child's ability to talk all the time, but not always out loud. An example is a child may describe an activity that they're doing, however for adults there was no need for the description of what they're doing because its easy to see, with an activity such as walking.

The third stage the concrete operational stage. The stage begins at the ages of 7 and continues until the child is about eleven or twelve. This stage consists of the child's ability to use logic and be able to solve problems that they face linguistically. However there is evidence that Piaget believed many people remained in this stage for life and never moved on to the forth stage called the formal operational stage.

The final stage begins at the earliest of eleven or twelve, and is where a child begins to use abstract reason to make mental distinctions between self and an idea its considering. A child will also learn the ability to use language to express their opinion and debate. 

Chomsky Vs. Skinner

Chomsky Vs. Skinner

Chomsky

Avram Noam Chomsky proposed in the 1960's that the Language Acquisition Device (LAD) concept is instinctive and enables an infant to acquire and produce language. This theory suggests that humans are bore with the instinct to acquire language. 

The main argument in favour of the LAD in the argument from the poverty of the stimulus, which argues that unless children have significant innate knowledge of grammar they would be unable to learn language as quickly as they do.
The idea of Chomsky's linguistic theory is that the ability to learn language is all biologically determined by every individual human and therefore is genetically transmitted by parents to their child(ren). Because of this he argues that all humans share a very similar linguistic structure despite an cultural differences. In this his theory is very different to that of the behaviourist B.F.Skinner, who instead argued that language is learnt through reinforcement.

Skinner

Skinner proposed the the operant conditioning chamber, which is also nick named the Skinner Box. He believed that a humans free will was actually an illusion and a humans behaviour was a result of certain actions being repeated over and over along with reinforcement, furthermore he also believed that any action a human made was only the result of the consequences of that action. For example, he believed that if the consequences were bad then the action would not be repeated again this is likely to be then cancelled out by negative reinforcement, however if the consequences were good then there would be a high chance of that action being repeated this is because it would likely be encouraged by those around the infant, which lead to positive reinforcement which for an infant would be praise, laughter and attention from their caregiver. This is what Skinner called the principle of reinforcement. This evidence then implied that this is how infants learn language and not through an innate ability.
