10 | Syntactic sentence processing Flashcards
Derivational theory of complexity
What factors make a sentence more complex to process
Complexity is increased by
- passive
- negation
- word order(Sub,Verb,Obj vs. Obj,Verb, Sub)
Clausal hypothesis
We divide sentences into clauses by chunking them
Usually by Verb phrases
Phoneme monitoring
The children [that were] playing in the hayloft startled the farmer’s wife.
Processing is easier/faster when explicit markers (“that where”) are NOT left out.
How does Prosody and punctuation effect proccesing?
It can change how we interprit the sentence:
What is this thing called love?
What is this thing called, love?
What, is this thing called love?
Garden path
Leads the listener/reader to an incorrect interpretation of the sentence
Newspaper headlines:
- Man held over betting shop killings freed
- Eye drops off shelf
- Two sisters reunited after 18 years in checkout queue

Goal: Building a syntactic tree. (Phrase maker)
Parser is deterministic: Can only build one tree at a time.
Tries to keep the syntax as simple as possible
Tries not to leave too much material unattached (not building into the syntactic tree under construction)
Parsing strategies
Late closure
Minimal attachment
Right Association
Late closure
When possible, attach material intro the clause or phrase currently being processed.
Minimal attachment
Attach incoming material into the phrase marker being constructed, using the fewest possible nodes consistent with the well-formedness rules of the language under consideration.
Right Association
New nodes are preferably attached to the lowest node.
If the LC and MA does not indicate otherwise…
Category ambiguity
A word can be of multiple categories
walk (noun or verb?)
Recency Principle
Preference to attach materiel to a recent point in the preding structure. (Alternative: The cost is a greater processing cost with more distant attachments)
The lamp near the painting of | the house that was damaged in the flood |
Predicate Proximity
Preference to attach relative clause to the NP that is closest to the verb in the main clause. (or otherwise that which is in the highest structure of the tree)
The lamp | near the painting of the house | that was damaged in the flood
