1. Mental Lexicon1. Mental Lexicon
How can we investigate the mental lexicon?
Main question: how is the mental lexicon organized? How do we retrieve words?

2. Collocates2. Collocates
What are some psycholinguistic ways to look at collocates?Psycholinguists usually take information from corpora and
use it to create stimuli . . . .

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

Why are response times slower for high frequency words?

b. eye movementsb. 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 otherThe freaky thing is that natives processed collocates
faster . . . Non native speakers processed non-collocates faster

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

What else we know. . .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

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
