Where
we are
We've looked at how words work:
á
Their
meanings and the cognitive processes underlying them are grounded in human
embodiment – they depend on the particularities of the individualŐs
interactions with the world, in a particular sort of body, with the sorts of
mental faculties we have, in the context of other humans, with social goals,
interactions, etc.
á
Moreover,
words can have multiple meanings or gain new meanings. We've seen cognitive
mechanisms for this like metonymy, metaphor, and construal.
á
The words
that a language has can influence how speakers of that language think - what
aspects of the world they attend to, how they categorize experiences, and what
they think is similar or different.
Grammar
The third part of the course addresses
how we productively combine words and morphemes to create more complex
structures, like complex words and sentences. This is grammar: the study of what people know about how words and
morphemes combine to produce meaningful patterns.
Background on Chomskian
linguistics
Until
the late 1950s, the study of the language of individuals was largely
behaviorist. The mind was treated like a black box, where all you could
study was what went in and came out of human language users.
- Noam
Chomsky, an MIT linguist, advocated viewing language instead as a window
to the mind, and language has since been embraced
as one as the major areas of cognitive science.
Properties of Chomskian
linguistics
- The
goal of Chomskian [aka Generative]
linguistics: make the study of language more rigorous, by developing a
formal model of language, which accounts for grammaticality.
- Chomsky
observed that there are more grammatical sentences than can be listed, due
to the compositionality of language.
The box is on the table in the
corner of the room at the top of the stairs in the back of the house...
- In fact,
language is recursive, so there's an infinite number of
grammatical utterances.
The monkey killed the student.
The monkey that the professor
trained killed the student.
The monkey that the professor
that the police were searching for trained killed the student.
- Language
on this view is a Generative system, which produces grammatical utterances
and not ungrammatical utterances.
I love my good monkey.
*I monkey my love good.
- The
Chomskian notion of grammaticality has nothing to do with meaning
Colorless green ideas sleep
furiously.
Why we
should be grateful to Chomsky
- Brought
language to prominence as a cognitive function - about 1/4 of talks at the
annual international Cognitive Science Society Conference are about
language
- Brought
rigor to the study of grammar
- Views
language as a mental function, not just as something shared by a community
But
there are lots of things that are profoundly wrong with a Chomskian approach to
language, based on a large number of unsubstantiated assumptions:
- The
study of language is the study of grammaticality
- What
is grammaticality? It's whether a sentence is grammatical or not, that
is, whether it is produced by a grammar or not. You see the circularity
here?
- Many
people use grammaticality judgments. But it's not clear what these mean
- They
conflate grammar, conventionality, meaning, pragmatics, use, context
- They
ask for an opinion, so they invite meta-linguistic processing
- They
can't be direct reflections of grammatical knowledge, because of the
competence-performance distinction, discussed below
- Language
is for communication, instruction, other social
purposes. Studying language through grammaticality judgments is like
studying running by asking people about what they think about how they
run. Why not study it directly?
- The
study of language need not be embedded in the study of language use
- You
can study sentences in isolation, and build theories to explain why
sentences are grammatical or not independent of the individuals who
actually use language or mechanisms the use for language.
- This
is so wrong, it's hard to even articulate.
- Syntax
is modular - i.e. it does not depend on any other aspects of language
- There
is no evidence for this, and we'll see some evidence against it.
- Language
is modular, i.e. it does not depend on any other cognitive mechanisms
- We've
already seen evidence against this.
- Variation
across individuals is irrelevant to grammar
- But
there's lots of variation across individuals, which in principle cannot
be accounted for by the Generative program, which studies an imaginary
"ideal speaker-listener, in a completely homogenous speech
community" [Chomsky, 1965:3]
- There
is a qualitative distinction between core
[universal] & peripheral
[language-specific] grammar
- Only
core grammar is part of
universal linguistic knowledge and therefore worthy of linguistic study.
If you assume this, you miss out on something like 90% of grammar.
- Strangely,
core and peripheral grammar are very similar in their patterning,
acquisition, and behavior. Must just be coincidence.
- Competence
is distinct from performance
- In
many contexts, the distinction between language knowledge, competence, and language behavior,
performance, is a reasonable
distinction, e.g. speech errors
- But
in practice, it is used to shield grammatical theory from actual language
use. Sentences can be deemed grammatical even though people judge them
ungrammatical. And vice versa.
E.g. multiple embedding of RCs.
- Meaning
is lexically compositional - only words and morphemes provide meaning.
- Patterns
for combining words and morphemes have no meaning - they are simply
different formal structures that are related through syntactic
transformations.
- We
will see that they differ in meaning, information structure, use, and
pragmatics
- Meaning
is logical, objective
- We've
seen that this is not true
On the
basis of these faulty assumptions and some bad reasoning, the Generative
approach comes to the incorrect conclusion:
- One speakerŐs
grammaticality intuition is evidence about all speakersŐ mental systems.
- The
fallacious reasoning here is exceptional. Assume that [contrary to
observation] all speakers of a language have the same grammar. Then
conclude that you can observe one individual and learn all there is to
know about the grammar of the language.
- Even
if the assumption were correct, the conclusion would not be. You cannot
fully understand the human genome by studying a single individual.
Construction Grammar
The
approach to grammar we will be adopting doesn't make any of these assumptions.
Rather:
- The
study of language is the study of all aspects of language behavior,
including meaning, interpretation, understanding, acceptability
- We
study language in terms of the way it's used, including the cognitive
mechanisms it uses
- We
are not theoretically predisposed against the possibility that syntax and
language more broadly aren't strictly modular
- We
assume no competence-performance distinction, but there is self-monitoring
- We make
no assumptions about variation.
- We
make no assumption about a core-periphery distinction
- We
make only two assumptions:
- Language
knowledge consists of form-meaning [or form-function] pairings, and these
may be more or less specific and more or less complex.
- Language
is embodied - that is, it is part of the human cognitive system.
