Sentence Comprehension Flashcards
What is parsing?
Determining the linguistic relationships among parts
Immediacy principle: Immediately after a word is heard or read…
… the meaning is accessed
… it is placed into the assumed syntactic structure
Benefit of the immediacy principle:
It’s really fast
Garden Path Sentences
Easy to misparse sentences
Support the immediacy principle
Immediate parsing can lead to errors because there’s a lot of assumption involved
Two approaches to parsing:
Modular approach: comprehension is the result of modules, each devoted to ONE aspect; only syntax is considered, semantics is not considered
Interactive approach: parsing involves more than just syntax, constraint-based model
Modular Approach
- Comprehension is the result of modules, each devoted to ONE aspect
- Only syntax is considered, semantics is not considered
- Parsing strategies –> use the simplest, easiest-to-construct phrase tree possible
- Two strategies: Late Closure Strategy, Minimal Attachment
Interactive Approach
- Parsing involves more than just syntax
- Constraint-based model: all available information is used in parsing; syntax and semantics are assumed to interact during comprehension
Late Closure Strategy
Attach items to the phrase currently being processed
“Close” clause boundaries at the latest point possible
E.g., Because Jay always jogs a mile… seems like a short distance to him
Frazier & Rayner (1982) - eye-tracking (for Garden Path sentences)
Minimal Attachment
Attach items so the fewest new constituents are created
Assumption: more constituents –> harder to process
Frazier & Rayner (1982) - The spy saw the cop…
-… with the binoculars but the cop didn’t see him –> MA works (2 ways to parse - who has the binoculars?)
-… with the revolved but the cop didn’t see him –> MA fails (must reparse)
Study looks at fixation duration - more fixation if you have to reparse
Rayner et al. (1983) - eye tracking study
Sentence 1: The florist sent the flowers was pleased (less plausible)
Sentence 2: The actor sent the flowers was please (more plausible)
(Modular approach says plausibility shouldn’t matter)
(If plausibility affects parsing, then interactive approach)
Results: found that people GP florist sentence; found people also GP actor sentence!
Plausibility didn’t matter - MODULAR SUPPORT
Trueswell et al. (1994) - eye tracking study
Does semantics matter? Does it affect parsing?
Modular prediction - no - semantics shouldn’t matter
Interactive prediction - yes - semantics matter
Results: GP for only one sentence - we use our knowledge to determine if MA is possible - INTERACTIVE SUPPORT
Ferreira & Clifton (1986) - Does context matter?
“The editor played the tape agreed it was a big story”
- Poor context given to some subjects
- Good context given to some subjects
Results: People GP with poor context and with good context; context has no effect - MODULAR SUPPORT
Boland (1997) - Does lexical preference matter? (“Preferred interpretation”)
Modular approach says lexical preference should matter
2 sentences:
-1. Jane saw her duck and fall down (preferred interpretation)
-2. Jane saw her duck and some eggs
Results: found that people didn’t GP sentence 1 (faster); we use lexical knowledge to help us parse - INTERACTIVE SUPPORT
We usually follow parsing strategies… but our parsing can be modified based on our _____________
