  2. Psycholinguistic ways of examining the lexicon/syntax Three things we will look at: • Mental Lexicon • Collocates • Influence of lexicon on sentence structure

  3. 1. Mental Lexicon How can we investigate the mental lexicon? Main question: how is the mental lexicon organized? How do we retrieve words?

  4. a. aphasia T: Now then, what’s this a picture of? (showing a picture of an apple) P: Ra-ra-rabbit. T: No, not a rabbit . . . It’s a kind of fruit. P: Fruit T: What kind of fruit is it? P: Oh this is a lovely rabbit. T: Not a rabbit. It’s an apple. P: Apple, yes. T: Can you name any other pieces of fruit? What other kinds of fruit would you have in a dish with an apple. P: Beginning with an A? T: No, not necessarily. P: O well rhubarb. T: Perhaps, yes. P: Rhubarb. T: What’s this boy doing? (showing a picture of a boy swimming.) P: O he’s in the sea. T: yes. P: Driving. . . driving. It’s not very deep. He’s driving with his feet, his legs driving. Well, er driving er diving. T: In fact, he’s . . . P: Swimming. T: Good, what about this one? (showing a picture of a boy climbing over a wall). P: Driving on a wall. T: He’s what? P: Dr . . . driving, he’s climbing on a wall.

  5. Is a robin a bird? Is a bad a bird? Is a goose a computer? Is a horse a mammal? Does a monkey have teeth? Does a pickle have fingernails? Does a bird have feet? Is a cow a bird? Is a tomato a vegetable? Does a bird have wings? Does an octopus run on batteries? Is a horse a mammal? Is robbery a crime? Is murder a crime? Is libel a crime? Is a shark dangerous? Is a cow dangerous? Is a cat dangerous? Did Abraham Lincoln have a beard? Is corn a vegetable? Which were easy to reject? Which were more difficult? b. Semantic Verification Task

  6. b. Semantic Verification Task

  7. 2. Collocates What are some psycholinguistic ways to look at collocates? Psycholinguists usually take information from corpora and use it to create stimuli . . . .

  8. a. response times research question: Are collocates stored as a single unit in the mental lexicon? Sosa & McFarlane, 2002

  9. a. response times Why are response times slower for high frequency words?

  10. b. eye movements Research question: Do native and non-native speakers of English process collocates and non-collocates similarly? Looked at eye movement response times (and what they looked at for both native and non-native speakers AND at both collocates and non-collocates Findings: Both groups processed one faster than the other The freaky thing is that natives processed collocates faster . . . Non native speakers processed non-collocates faster Why? Gerard, 2008

  11. 3. Lexicon and sentence structure a. lexical priming b. syntactic priming main question: what aspects of the lexicon/syntax determines what sentence structure we use?

  12. a. lexicon

  13. What else we know. . . • Animate objects chosen as subjects • Humans chosen as subjects • More frequent word chosen as subjects • Phonological priming (especially rhyming) more likely to cause word to be chosen than semantic priming • Age that word is learned determines which word is chosen as subject

  14. The woman dialed 911 to report an emergency situation in her building.

  15. The car’s windshield was struck by a brick.

  16. One of the fans punched the referee.

  17. Bock & Griffin (2000)

  18. b. syntax • a: The ghost sold the werewolf a flower • a: The man gave the woman a box • Bock (1986): syntactic persistance tested by picture naming • b: The ghost sold a flower to the werewolf • b: The man gave a box to the woman

  19. b. syntax • Bock (1989): global syntactic role matters, syntactic priming does not depend on lexical similarity • a: The werewolf baked a cake for the witch • b: The snowman brought a book to the boy • NP V NP PP • c: The snowman brought a book to study

  20. b. syntax • Manipulations of roles: The foreigner was loitering by the traffic light The boy is being woken by the alarm clock • Manipulations of verb form: Same vs different tense (hands/handed) Same vs different number (hands/hand) Same vs different aspect (hands/is handing) Bock & Loebell (1990)

  21. b. syntax How long does syntax priming last? Bock & Griffin (2000) used same stimuli but varied the amount of time between stimuli and showing Picture from 0 to 2 sentences Bock & Griffin (2000)

  22. b. syntax How long does syntax priming last? Bock & Griffin (2000

  23. Even longer . . .

  24. b. syntax In real life, syntactic priming seems to occur as well Branigan, Pickering, & Cleland (2000): Speakers tend to reuse syntactic constructions of other speakers Potter & Lombardi (1998): Speakers tend to reuse syntactic constructions of just read materials It may be a feature that helps us to learn language . . . . Researchers are now using priming to teach second languages
