From thought to speech Grammatical class constraint
Most substitutions, exchanges, and blends involve words of the same grammatical class
Slots and frames A syntactic framework is constructed, and
then lexical items are inserted into the slots

Grammatical class constraint:
If the word isn’t the right grammatical class, it won’t “fit” into the slot.

Syntactic priming 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
![Page 14: PSY 369: Psycholinguistics Language Production: A General Model.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d0e5503460f949e46fb/html5/thumbnails/14.jpg)

“The rhythm of the lost word may be there without the sound to clothe it; or the evanescent sense of something which is the initial vowel or consonant may mock us fitfully, without growing more distinct.” (James, 1890, p. 251)
Tip-of-the-tongue
![Page 22: PSY 369: Psycholinguistics Language Production: A General Model.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d0e5503460f949e46fb/html5/thumbnails/22.jpg)
Low-frequency words (e.g., apse, nepotism, sampan), prompted by brief definitions.
On 8.5% of trials, tip-of-the-tongue state ensued:
Had to guess: word's first or last letters the number of syllables it contained which syllable was stressed
Brown & McNeill (1966)
Tip-of-the-tongue
![Page 23: PSY 369: Psycholinguistics Language Production: A General Model.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d0e5503460f949e46fb/html5/thumbnails/23.jpg)
Total of 360 TOT states: 233 ="positive TOTs" (subject was thinking of target
word, and produced scorable data 127 = "negative TOTs" (subject was thinking of other
word, but could not recall it) 224 similar-sound TOTs (e.g., Saipan for sampan)
48% had the same number of syllables as the target 95 similar-meaning TOTs (e.g., houseboat for
sampan). 20% had same number of syllables as target.
Tip-of-the-tongue Brown & McNeill (1966)

Similar words come to mind about half the time but how much is just guessing?
First letter: correct 50-71% of time (vs. 10% by chance) First sound: 36% of time (vs. 6% by chance)
Tip-of-the-tongue

Results suggest a basic split between semantics/syntax and phonology: People can access meaning and grammar
but not pronunciation
Tip-of-the-tongue
![Page 26: PSY 369: Psycholinguistics Language Production: A General Model.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d0e5503460f949e46fb/html5/thumbnails/26.jpg)
Semantics Syntax
grammatical category (“part of speech”) e.g. noun, verb, adjective
Gender e.g. le chien, la vache; le camion, la voiture
Number e.g. dog vs. dogs; trousers vs. shirt
Count/mass status e.g. oats vs. flour
Tip-of-the-tongue
![Page 27: PSY 369: Psycholinguistics Language Production: A General Model.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d0e5503460f949e46fb/html5/thumbnails/27.jpg)
Vigliocco et al. (1997) Subjects presented with word definitions
Gender was always arbitrary If unable to retrieve word, they answered
How well do you think you know the word? Guess the gender Guess the number of syllables Guess as many letters and positions as possible Report any word that comes to mind
Then presented with target word Do you know this word? Is this the word you were thinking of?

Vigliocco et al (1997)
Results + TOT: 84% correct gender guess - TOT: 53% correct gender guess
chance level Conclusion
Subjects often know grammatical gender information even when they have no phonological information
Supports split between syntax and phonology in production
Vigliocco et al. (1997)

Central questions How many levels are there? What is the scope of planning? Are the stages discrete or cascading? Is there feedback in lexicalization:
interactive or not?

From thought to speech How does a mental concept get turned into a spoken utterance? Levelt, 1989, 4 stages of production:
1 Conceptualising: we conceptualise what we wish to communicate (“mentalese”).
2 Formulating: we formulate what we want to say into a linguistic plan.– Lexicalisation
– Lemma Selection– Lexeme (or Phonological Form) Selection
– Syntactic Planning3 Articulating: we execute the plan through muscles in the vocal tract.4 Self-monitoring: we monitor our speech to assess whether it is what we
intended to say, and how we intended to say it.
![Page 46: PSY 369: Psycholinguistics Language Production: A General Model.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d0e5503460f949e46fb/html5/thumbnails/46.jpg)
Models of production As in comprehension, there are serial
(modular) and interactive models Serial models - Garrett, Levelt et al. Interactive models - Stemberger, Dell
Levelt’s monitoring stage (originally proposed by Baars) can explain much of the data that is said to favour interaction between earlier levels

An model of sentence production Three broad stages:
Conceptualisation deciding on the message (= meaning to
express)
Formulation turning the message into linguistic
representations Grammatical encoding (finding words and
putting them together) Phonological encoding (finding sounds and
putting them together)
Articulation speaking (or writing or signing)
