Theorists for acquiring language
Chomsky (Nativist theory)
He believed learning takes place through an innate brain mechanism that has the ability to acquire grammatical
structures. This was known as the Language Acquisition Device (LAD). He argued there was such thing as universal
grammar where human language is similar.
Chomsky argued CDS is ineffective because of its repetitive nature.
All children roughly gain the same language features at No location of the brain mechanism has been found.

There is similar grammar throughout languages. Based on anecdotal evidence.
On a lexical level, words may be similar through Case studies of people with no social interaction until the

Piaget (Cognitive theory)
He believed children are active learners who use their environment and social interactions to shape their language.
Linguistic development occurs as children understand concepts surrounding the word's meanings. This suggests that
children cannot be taught until they are cognitively ready.
Stage Age (years) Description
Sensorimotor -2 Children experience the world through their senses and begin classifying
language as a result of their physical qualities. Object permanence
develops which is the concept that objects exist out of sight.…read more

Clark's overextensions-Eve Clark studied overextensions and found they base them on the physical qualities
of objects and features such as taste, sound, movement, shape, size and texture.
Clark's adjectives-she found that common adjectives (e.g. nice and big) are developed in the first 50 words,
however, spatial adjectives are acquired later (e.g.wide/narrow).…read more

Nomination: object/person labelled, e.g. there mam.
Recurrence: event repeated, e.g. more cats.
Negation: is something denied? E.g. no food.
Bellugi's negative formation-she proposed the three stages of negative formation. Stage one involves using
no at the beginning/end of the sentence. Stage two is using no inside the sentence. Stage three is attaching
the negative to auxiliary verbs.
Bellugi's pronoun formation-she proposed the three stages of pronoun formation. The first stage was where
the child uses their own name.…read more
