Sentences are broken down into noun and verb phrases, which are in turn broken down into their constituent parts. The example in Figure 2 is a simple one. These phrase structure trees can be very complex, though children have little difficulty creating the sentences to accompany them. Semantic processing Semantic processing is developing even before an infant begins to use words. Words initially begin with a single meaning then become more rich as the child is exposed to a wide range of words and experiences, some of which may be the same but used in different contexts, and some that are related to each other.
Meaning is assembled in semantic networks in which words are inserted in classes.
Later these animals will be distinguished from each other and two classes will be form. They may also contain tactual and kinesthetic information, cognitive processing strategies, and metacognitive strategies. These make up skills, or networks of procedural knowledge. Semantic networks form relatively late as compared to the other aspects of language and continue to develop throughout life as new things are learned. The development of these networks can be identified through word association tasks, as associated words tend to differ with age.
