Essay On Child Language Development
Chomsky claimed that there was a critical period for language learning which was first proposed by Eric Lenneberg.
He claimed, as Cook Newson (191) explain, that there is a critical period during which the human mind is able to learn language; before or after this period language cannot be acquired in a natural fashion.
However, this theory is contradicted by the ‘cocktail party chatterer’ children.
Singleton evaluates the scenario in these words, “The one qualification that might be entered with regard to such evidence is that deprivation of language input during the phase in a child’s life when cognitive development is at its most intense may have quite general psychological/cognitive effects, and that it may be these general effects that are reflected in later language development rather that effects relating specifically to a critical period for language” (Singleton 1989, 54).
This means that children’s logic and thinking methods are originally different to adults.
Piaget’s cognitive theory suggests language is one of many cognitive behaviours, and it emerges from cognitive development or learning to think and problem solve.
Piaget’s Cognitive Theory identifies language as an element of knowledge acquisition.
He believed that “the growth of knowledge is a progressive construction of logically embedded structures replacing one another by a process of inclusion of lower, less powerful logical means into higher and more powerful ones up to adulthood”.
