Document Summary
Language the rule-directed used of symbols to convey a message. Symbolic present objects, ideas; can reflect to things in the past, present, future, not in physical proximity, etc. Semantic the symbols are arbitrary but they"re used to convey a meaning. Generative it evolves based on new needs. 2 months attend ore to speech sounds than non-speech sounds. 3-4 months can distinguish phonemes from all languages (ability lost after 4 months) Fast mapping dramatic increase in vocabulary because the child associates a word with a concept after only one exposure two words. Overregularization incorrectly generalizing a rule to an irregular case. E. g i drawed a picture (the verb draw is irregular) By 3 years old four- and five-word sentences. Overextension incorrect generalization of a word to other similar objects or actions. Underextension use of a word to describe a narrower set of objects than it intended. Possible that there"s a critical period to learn a language/sensitive period for language development.
