Children exemplify several key properties of language development. The statements are cryptic: when children first learn to speak, they include only essentials, omit many prepositions, articles, adverbs. Children engage in variety of mental activities that enable them to comprehend and produce speech. Well-developed auditory perception system allows them to divide speech into individual words. Accurate perception of other people"s speech and their early-developing ability to imitate help them learn to pronounce words correctly. Children attend to meanings meaning is an intelligent approach to language acquisition. Phonology: concerns the structure and sequencing of speech sounds, developed soon after birth. Involves the ways that phonology, syntax, and semantics are used to convey messages to other people and to understand what they have in mind. Children"s developing knowledge of these aspects is reflected in both their ability to comprehend language and to produce it: comprehension precedes production for all aspects.
