surface structure

deep structure

transformational grammar
rules that transform among surface structures having the same deep structure
paraphrase
different surface structures have the same deep structure

syntactic
referential
lexical ambiguity
a word has multiple meanings
syntactic ambiguity
the same words can be grouped together into more than one phrase structure
referential ambiguity

how do we process language?
hear sounds
identify phonemes from the sounds
identify morphemes and words from the phonemes
lexical access
put words into phrases
figure out phrase structure of the sentence
compute the sentence’s meaning
figure out how the sentence fits into the context of the conversation
McGurk effect
the phoneme one hears depends on visual input
phonemic restoration effect
the brain can fill in missing phonemes using context
