8. Summary of Sentence Processing Strategies
1. "Divide each sentence up into sentoids by
looking for NP—V (—NP) sequences
('canonical sentoid strategy')

4. Use your knowledge of the world to pick the
most likely interpretation. "

11. Sentence Comprehension Model
1. Parse the sentence
2. Look words up in mental lexicon as they are presented
3. Access meaning and grammatical categories (activating related nodes along the way)
4. Construct a syntactic representation [we use trees when we diagram them]
5. Sentence meaning is built up from the meaning of the component words and sentence structure

12. Grice's Maxims of Conversation
1. Quantity Be informative
2. Quality Be truthful

13. Speech Acts: Function and Form
Speech Act Sentence Type
Function Form
assertions declarative
questions interrogative
orders imperative
requests imperative

14. Stage Model of the Interpretation of Indirect Speech Acts (Searle, 1975)
1. Listener extracts literal meaning.
2. Listener decides if the literal meaning is what
was intended
3. If not, listener computes intent using context
and communicative conventions
Carroll, David W Psychology of Language, third edition. Pacific Grove: Brooks/Cole Publishing Company, p. 141.

15. Stage Model of the Interpretation of Metaphors (Grice, 1975; Miller, 1979; Searle, 1979)
1. Listener recognizes that sentence is not
literally true
2. Listener searches for another possible
meaning using convention of quality
Carroll, David W Psychology of Language, third edition. Pacific Grove: Brooks/Cole Publishing Company, p. 143.

16. Factors in Memory for Sentences -1
1. We store the meaning (or "gist")
2. We do not seem to retain the exact form
(except for "pragmatically striking" utterances)
3. We tend to draw (non-linguistic) inferences
and store these
4. Stored inferences tend to be remembered as
WHAT we heard rather than an inference
based on what we heard.

17. Factors in Memory for Sentences -2
"All of these considerations suggest that a linguistically based representational system (such as deep structure in transformational grammar) is a poor candidate for a model of sentence memory."
Carroll, David W Psychology of Language, third edition. Pacific Grove: Brooks/Cole Publishing Company, p. 151.

18. Propositions (61) George hit Harry. (62) Hit (George, Harry)
(63) Harry was hit by George.

Argument = N, ProN
