What is Parsing?
Process by which words in a message are transformed into a mental representation of the combined meaning of the words
What are constituents in Parsing?
Constituents in Parsing are subpatterns that correspond to basic phrases, or units, in a sentence’s structure
Identification of constituent structure is important to the parsing of a sentence
What do participants do during comprehension (parsing)
– Process the meaning of a sentence one phrase at a time
– Maintain access to a phrase only while processing its meaning
what did Jarvella (1971)’s study include?
Jarvella (1971) had people listen to long passages of speech. Interruptions during the passages were cues to the participants to recall, as precisely as possible, whatever they could from the sentence just heard. Jarvella created passages that contained identical phrases, except that the phrases “belonged” to different clausal constituents.
What is the immediacy of interpretation in parsing?
– People try to extract meaning out of each word as it arrives
– They do not wait until the end of a phrase to decide on how to interpret a word
what did Just and Carpenter’s (1980) study find?
Participants fixated longer on unfamiliar or surprising words while reading a sentence
what did Berkum et al. (1999) study find?
The cat entered the room suddenly, startling a mouse which had found a bit of cheese in the corner.
The mouse quickly/slowly returned to its hole
quickly = predictable slowly = unpredictable
how do people process sentences according to parsing?
- People process a sentence as each word comes in
- However, the meaning of a sentence is defined in terms of the phrase structure
- Thus, some of the information cannot be processed until the phrase is complete
What is permanent ambiguity in parsing?
- Ambiguity remains to the end of a sentence
* e.g., Flying planes can be dangerous.
What is transient ambiguity in parsing?
• Ambiguity is resolved by the end of a sentence
• e.g., The old train…
… left the station.
… the young.
what is the principle of minimal attachment in parsing?
The parser builds the simplest syntactic structure possible (that is, the one with the fewest phrasal nodes).
– One interprets a sentence in a way that causes minimal complication of its phrase structure
The horse raced past the barn fell.
The woman painted by the artist fell.
– If ambiguity is resolved within a phrase, we are often unaware of dealing with the ambiguity
how do we deal with lexical ambiguity according to Swinney?
The man was not surprised when he found several spiders, roaches, and other bugs in the corner of the room.
– Lexical decision task
• spy, ant, or sew
– When they were presented within 400 ms of the prime word (bugs), recognition of both spy and ant was facilitated
– If the delay was more than 700 ms, only the elated word (ant) was facilitated
According to parsin, what do people do when presented with ambiguous words?
When an ambiguous word is presented, participants select a particular meaning
within 700 ms
what are the two syntactic cues that are used to interpret a sentence?
– Word order
– Inflectional structure
Him kicked the girl.
The girl kicked he.
The girl kicked him.
He kicked the girl.
what else is used to interpret a sentence and what was an experiment that supported this?
Semantic cues are also used Jane fruit eat [Jane eat(s) fruit] • Fillenbaum (1971, 1974) 1. John was buried and died. 2. John died and was buried. – When asked to paraphrase the sentence #1 above, about 60% of the participants generated a sentence that had the same meaning as #2
how are syntactic and semantic cues integated?
Syntactic and semantic cues are integrated to arrive at an interpretation of a sentence
What was Typer and MArslen-Wilson (1977)’s study?
– If you walk too near the runway, landing planes are
– If you’ve been trained as a pilot, landing planes are
How do we combine syntactic and semantic cues?
through interactive processing
what is interactive processing?
– Syntactic and semantic cues are simultaneously processed
– People appear to be able to use semantic information immediately to guide syntactic
