Syntax: the ordering of the words A dog bites a man. A man bites a dog. A dog was bitten by a man. Not just the linear ordering It is the underlying set of syntactic rules

Not just the linear ordering It is the underlying set of syntactic rules Syntax: the ordering of the words

Generative Grammar The pieces: – Grammatical features of words Grammatical class: Dog:noun; Bite:verb Other Features like: grammatical number & gender – Phrase structure rules - these tell us how to build legal structures S --> NP VP VP --> V (NP) NP --> (A) (ADJ) N (PP)

Transformational grammar Chomsky (1957, 1965) Two stages phrase structures for a sentence Build Deep Structure Build from phrase structure rules One constituent at a time Convert to Surface Structure Built from transformations that operate on the deep structure Adding, deleting, moving Operate on entire strings of constituents S --> NP VP VP --> V (NP) NP --> (A) (ADJ) N Passive transformation rule: NP 1 + V + NP 2 ---> NP 2 + be + V + -en + by + NP 1

Transformational grammar 1 deep structure, 2 surface structures: Active/passive sentences: The man bit the dog. The dog was bitten by the man. 2 deep structures, 1 surface structure: Groucho Marx shot an elephant in pajamas Passive transformation rule: NP 1 + V + NP 2 ---> NP 2 + be + V + -en + by + NP 1

Psychological reality of syntax Derivational theory of complexity (pp ) The more transformations, the more complex The man was bitten by the dog. The man was bitten. (involves deletion) No evidence for more processing of the second sentence

Semantics The study of meaning Arbitrariness Words are not the same as meaning Words are symbols linked to mental representations of meaning (concepts) Even if we changed the name of a rose, we wouldn’t change the concept of what a rose is “What’s in a name? that which we call a rose By any other name would smell as sweet.”other name

Separation of word and meaning Concepts and words are different things Translation argument Every language has words without meaning, and meanings without words e.g., transmogrify, wheedle, scalawag Imperfect mapping Multiple meanings of words e.g., ball, bank, bear Elasticity of meaning Meanings of words can change with context e.g., newspaper

Semantics Philosophy of meaning Sense and Reference (Frege 1892/1952) “The world’s most famous athlete.” “The athlete making the most endorsement income.” 2 distinct senses, 1 reference Now In the 90’s Over time the senses typically stay the same, while the references may change

Semantics Two levels of analysis (and two traditions of psycholinguistic research) Word level (lexical semantics) How do we store words? How are they organized? What is meaning? How do words relate to meaning? Sentence level (compositional semantics) How do we construct higher order meaning? How do word meanings and syntax interact?

Lexical Semantics Word level The (mental) lexicon: the words we know The average person knows ~60,000 words How are these words represented and organized? Dictionary definitions? Necessary and sufficient features? Lists of features? Networks?

Word and their meanings “John is a bachelor.” What does bachelor mean? What if John: is married? is divorced? has lived with the mother of his children for 10 years but they aren’t married? has lived with his partner Joe for 10 years?

Word and their meanings I’m going to give you a word. Write down the first word you think of in response to that word. CAT How are your words related to ‘cat’?

Lexical Ambiguity What happens when we use ambiguous words in our utterances? “Oh no, Lois has been hypnotized and is jumping off the bank!”

Money “bank” River “bank”

Lexical Ambiguity Psycholinguistic evidence suggests that multiple meanings are considered Debate: how do we decide which meaning is correct Based on: frequency, context Hmm… ‘bank’ usually means the financial institution, but Lois was going fishing with Jimmy today …

Compositional Semantics Phrase and sentence level Some of the theories Truth conditional semantics: meaning is a logical relationship between an utterance and a state of affairs in the world Truth conditional semantics Proposition: A relationship between two (or more) concepts Has a truth value Jackendoff’s semantics Jackendoff’s Concepts are lists of features, images, and procedural knowledge Conceptual formation rules Cognitive grammar Mental models - mental simulations of the world

Pragmatics Sentences do more than just state facts, instead they are uttered to perform actions How to do things with words (J. L. Austin, 1955 lectures) Using registers Conversational implicatures Speech acts

Pragmatics Registers: How we modify conversation when addressing different listeners Determine our choice of wording or interpretation based on different contexts and situations Speech directed at babies, at friends, at bosses, at foreigners

Pragmatics Conversational implicatures Speakers are CooperativeCooperative Grice’s Conversational MaximsConversational Maxims Quantity: say only as much as is needed Quality: say only what you know is true Relation/Relevance: say only relevant things Manner: Avoid ambiguity, be as clear as possible

Pragmatics Speech acts: How language is used to accomplish various ends Direct speech acts Open the window please. Clean up your room! Indirect speech acts “It is hot in here” “Your room is a complete mess!” Non-literal language use e.g., Metaphors and idioms

Pyscholinguistics and pragmatics Three-stage theory Stage 1: compute the literal interpretation of the utterance Stage 2: evaluate the interpretation against assumptions Grice’s conversational maxims Stage 3: if interpretation doesn’t seem correct, derive (or retrieve) non-literal interpretation One stage approaches Evaluate utterance at multiple levels simultaneously and select the appropriate one Use context to derive the single most-likely interpretation
