- study of WORDS and their MEANINGS
- RULES used to describe STRUCTURE and LANGUAGE
- how people use LANGUAGE to COMMUNICATE
How do infants perceive speech
- Babies hear phonemes
- Biologically prepared to learn language

- Melody of language is important
- take turn, pause, wait
- first words around first birthday
What is name explosion and fast mapping?
Name explosion: learn words rapidly 2-200 in the first 2 years
Fast mapping: learning words meaning so rapidly that the child cant be considering all possible meanings
How do Children figure out the meaning of words? What strategies do they use?
- Joint Attention:
- Constraints:Sentence Cues:
What is over extenstion, underextension, and overregularization
How does the production of sentences develop?
Telegraphic in 2 year olds
- Gradually adds gramatical morphemes
- (words or endings of words that make sentence gramatical)
Mastery of grammar by rule based learning errors of overregularization occur
3-6 years- learn negation, use embedded sentences understand passive voice
What is Temperament?
- behavioral styles that are fairly stable across situations
- biologically based
What are the 9 temperamental dimensions of Thomas and Chess's theory?
