Chapter 11 – Language Structure
Linguistics
Linguistics – studies the structure of natural language.
Psycholinguistics – studies the way people process natural language.
Linguistics focuses on: Productivity – an infinite number of
utterances are possible in any language. Regularity – utterances are systematic in
many ways.
Grammar
Words can be combined into trillions of novel sentences, but not randomly. From runners physicians prescribing a
states joy rests what thought most. Grammar is a set of rules that generates
acceptable sentences and rejects unacceptable ones.
Three Kinds of Grammar
Syntax – word order and inflection (where emphasis is placed). Did hit the girl the boys?
Semantics – meaning of sentences. Colorless green ideas sleep furiously. Sincerity frightened the cat.
Phonology – sound structure of sentences (pronunciation).
Prescriptive vs Descriptive
Linguistic intuition – speakers can make judgments about utterances without knowing the explicit rules.
Ambiguities: They are cooking apples – structural. I am going to the bank – lexical.
Everyday speech (performance) does not conform to linguistic theory (competence).
Phrase Structure
Important to both linguistics and psychology of language processing.
Phrase structure – the hierarchical division of the sentence into phrases. Verb phrase Noun phrase
Rewrite rules – rules for generating sentences out of the parts.
Pauses
When people produce sentences, they generate a phrase at a time. Pauses occur at the boundaries of
phrases. Pauses are longer at boundaries of major
phrases compared to minor ones. Pauses occur at the smallest level above
the word that bundles coherent semantic information (meaning).
Speech Errors
Errors show the reality of phrase structure. When people repeat themselves they tend
to repeat or correct a whole phrase. Anticipation – an early phoneme is
changed to a later phoneme (toin coss) Occurs within a phrase – 13% across
phrases Word errors can occur across phrases –
83%
Transformations
Some constructions seem to violate phrase hierarchy: Whom is the dog chasing down the street? The dog is chasing whom down the street?
A transformational grammar has been proposed which hypothesizes a deep structure that guides such violations. This idea about grammar is controversial.
