FIRST LANGUAGE ACQUISITION

PHONOLOGICAL DEVELOPMENT
Children seem to be born with a perceptual system that is especially designed for listening to speech.

Newborns respond differently to human voices than to other sounds, they show a
preference for the language of their parents over other languages

THE STUDY OF L.A
the development of linguistic skills must involve the acquisition of a grammar.

A simple memorization of a list of words and sentences do not equip learners to understand unknown sentenses.

VOCABULARY DEVELOPMENT
By age eighteen months or so, the average child has a vocabulary of fifty words or more.

words that resemble nouns constitute the largest class in the early education of the child.

words similar to verbs and adjectives the next most frequent types of categories.
Among the most frequent words are expressions of disgust or rejection

Naturalistic approach

Experimental Approach

METHODS AND APPROACHES
Language acquisition focuses on children’s early expression,
the order in which they emerge, and the kinds of errors they contain.

provides children with the opportunity to experiment with and
begin to gain control over their vocal apparatus—an important prerequisite for later speech.

Investigator make use of specially designed tasks to getting linguistic activity relevant to the phenomenon that they wish to study. The child’s
performance is then used to formulate hypotheses about the type of grammatical system
acquired at that point in time.

Experimental studies usually employ tasks that test children’s comprehension, production,
or imitation skills.

Naturalistic studies tend to be longitudinal in that they examine language development
over an extended period of time,
longitudinal studies take a long time to conduct, but they have the advantage of permitting observe development.
