Prescriptivism and Descriptivism September 19, 2012
Current Work with Bonobos • After Nim Chimpsky, funding for primate language studies mostly dried up. • …although a few experiments went on. • One project involves bonobos, a sub-species of chimpanzees. • Bonobos Sherman and Austin have also been trained to use lexigrams. • Kanzi learned just by watching Sherman and Austin’s training! • But the Bonobo project is now in trouble—check out: • http://news.iowapublicradio.org/post/bonobo-hope-great-ape-trust-sanctuary
Mission Objectives • Wrap up Prescriptivism ~ Descriptivism • Try to figure out how language can be creative. • The previous problems with prescriptivism: • Confusion about application of prescriptive rules • (they’re not natural) • Hypercorrection • Standards can shift over time • Prescriptive rules form a poor understanding of natural language.
Problem #3: Missing Patterns • Prescriptivist rules do a poor job of accounting for many of the patterns we find in natural language. • Here’s one prescriptive rule which misses a consistent pattern: • “Incorrect”: I feel bad (about the accident). • “Correct”: I feel badly (about the accident). • Why? The verb “feel” should be modified by an adverb (“badly”), not an adjective (“bad”). • But is bad/badly modifying the verb or the subject of the sentence?
Linking Verbs • How about these examples? • Bob is happy. (*Bob is happily.) • Susie looks hot. (*Susie looks hotly.) • The water seems fine. (*The water seems finely.) • I feel sleepy. (*I feel sleepily.) • James Brown feels good. (*James Brown feels well.) • The verbs in these sentences are known as linking verbs. • They connect the subject to some property describing the subject. • (They do not modify the verb itself.)
Different Standards • Rules for a standard form of a language… • Normally describe the variety of language used by the group in power. • Other forms of the language are non-standard. • And are often identified with social, regional or ethnic groups. • Linguists have discovered that all forms of language (standard or not) are rule-based and orderly. • Non-standard forms of the language are not simply mistake-ridden versions of the standard form. • There is no linguistic reason to consider one variety of language superior to another.
Quick Write:Appalachian English • Appalachian English is a variety of English traditionally spoken in the Appalachian mountains. • Developed (and maintained) unique features due to isolation from outside communities. • One interesting feature: • a-prefixing…
“a” Prefixing Summary • [a-] form cannot be a noun (#1 and #5) • [a-] form cannot be an adjective (#2 and #6) • [a-] form cannot be preceded by a preposition • (#3 and #7) • first syllable of [a-] form must be stressed (#4 and #8) • Note: people often consider speakers of Appalachian English to be unsophisticated • …but the proper use of the [a-] prefix involves a relatively complex set of conditions.
AAVE • Another variety of English that has (traditionally) been low on the prestige scale is African-American Vernacular English (AAVE). • a.k.a. Black Vernacular English (BVE), Ebonics • Predominantly spoken by African-Americans • but not all African-Americans… • and some others, as well. • AAVE has a variety of interesting features... • some familiar: multiple negation, ain’t as an auxiliary • others are less familiar…
AAVE Verbs • Verb conjugation: third personal singular verbs lack an [-s] marker. • Ex: He look, it do, she have • “Paradigm leveling” • = making a set of related forms more uniform • (similar to “he don’t”/”she don’t”) • Under certain conditions, the verb “to be” can be deleted. • Ex: you so crazy, she workin’, he lucky • In the same conditions, “to be” can be contracted in standard English: • You’re so crazy, she’s working, he’s lucky…
To Be Deletion • What are the right conditions for deletion/contraction? • AAVEStandard English • You so crazy. You’re so crazy. • *He as nice as he say he. *He’s as nice as he says he’s. • *Here I. *Here I’m. • They mine. They’re mine. • *How beautiful you. *How beautiful you’re. • The verb needs to link the subject to something after it.
AAVE: Habitual Be • AAVE also has a form of “to be” that standard English does not. • “habitual” be • Habitual be expresses something that the subject does on a regular basis. • Examples: • He be working at Tim Horton’s. • She be late. (= She is usually late.) • She late. (= She’s late (right now).) • Do you be tired? (=Are you often tired?)
Descriptive Benefits • Language tends to operate in patterns, even if they are non-standard. • Important: Appalachian English and AAVE speakers are not just speaking English with mistakes. • Descriptive linguistics enables us to understand how those patterns work. • Even if you want to change the world, you’re better off understanding how it works to begin with. • History of economics analogy.
To Be Fair • Standards are useful because they provide a single form of the language to teach to non-native speakers. • They help establish uniformity in the written language. • They can help clear up confusions. • for instance: supposably • They also help to distinguish those who have mastered the arbitrary rules from those who haven’t. • (for better or worse) • Otherwise: • They are not useful for (scientific) linguistic analysis.
Linguistic Creativity (again) • One of the crucial design features of language was creativity (or productivity). • Charles Hockett: • “Language users can create and understand completely novel messages.” • “In a language, new messages are freely coined by blending, analogizing from, or transforming old ones. This says that every language has grammatical patterning.” • “In a language, either new or old elements are freely assigned new semantic loads by circumstances and context. This says that in every language new idioms constantly come into existence.” • How is it possible for human beings to do this?
To Infinity and Beyond • Last week, we found out that honeybees can produce a variety of different “dance messages”. • = “Food source beyond 65 feet, fly at 0 • degree angle with the sun.” • = “Food source beyond 65 feet, fly at 45 • degree angle with the sun.”
To Infinity and Beyond • The number of different messages the bees can produce is limited only by the number of angles they can differentiate: • “Food source beyond 65 feet, fly at 1 degree angle with the sun.” • “Food source beyond 65 feet, fly at 2 degree angle with the sun.” • …………… • “Food source beyond 65 feet, fly at 359 degree angle with the sun.” • Q: Can the bees dance at angles they haven’t seen before? • If so, how?
Different Infinities • What kind of infinities exist in human language? • Note that we can say (translations of) everything the bees can say: • Fly at a 1 degree angle with the sun. • Fly at a 2 degree angle with the sun. • …………… • Fly at a 359 degree angle with the sun. • • We can get as detailed as we want to about it, too: • Fly at a 45 degree, 13 minute, 27.6685 second angle with the sun.
Infinity + 1 • In addition to the infinity of things the bees can say, we can say other things, too. • Examples (borrowed from Ray Jackendoff): • A numeral is not a numbskull. • A numeral is not a nun. • A numeral is not a nunnery. • …………… • A nun is not a nursery. • …………… • An oboe is not an octopus.
Linguistic Infinities • These are uninteresting, but novel sentences. • In order to understand them, you must know the rule by which they are constructed. • Rule: • [Sentence] = A X is not a Y. • Point: • Knowledge of rules is more abstract than just knowledge of sentences.
Language Model #1 • In this model, all we “know” are the individual sentences we can use in language. • (no rules) • This is a good enough model to describe the vervets’ (or prairie dogs’) “language”. A nun is not a nursery. Fly at a 45 degree angle with the sun. I like linguistics.
Language Model #2 • In this model, we “know” all the rules we can use to combine words to form sentences in a language. • This is a good enough model to describe the bees’ “language”. • Is it good enough for human language? A X is not a Y. X at a Y degree angle with the Z. X likes Y.
What do you think? • No. There are even bigger infinities. • Check out these sentences: • Bill thinks that Beth is a genius. • Sue suspects that Bill thinks that Beth is a genius. • Charlie said that Sue suspects that Bill thinks that Beth is a genius. • Jean knows that Charlie said that Sue suspects that Bill thinks that Beth is a genius. • ad infinitum... • Some “real” examples:
How many rules do we need? • X verbs that Y is a Z. • W verbs that X verbs that Y is a Z. • V verbs that W verbs that X verbs that Y is a Z. • and so on… • Q: Can we store all these patterns in our heads? • A: No, because no matter how many we store, there is always a longer one… • So how do we know all of these sentences?
Language Model #3 • Jackendoff: “We know not just patterns of words, but patterns of patterns.” • This is how we can be infinitely creative with a finite set of rules. S = X likes Y. S = A X is not a Y. S = X verbs that S.
Check it out • Included among the infinite number of things we can say is a lot of complete nonsense. • Examples (from Chomsky and Lewis Carroll): • Colorless green ideas sleep furiously. • I’m memorizing the score of the sonata I hope to compose someday. • ‘Twas brillig, and the slithy toves • Did gyre and gimble in the wabe… • Check out the postmodernism generator: • http://www.elsewhere.org/pomo/
What’s the difference? • Nonsense sentences work because they fit in with the patterns formed by the sentences that actually do make sense. • (and that we use every day) • Compare with the following: • Large green lizards sleep soundly. • I’m memorizing the score of the sonata I hope to perform someday. • ‘Twas evening, and the slimy toads • Did squirm and wiggle in the cage…
What’s the difference? (part 2) • But the following sentences don’t work at all: • Green sleep ideas furiously colorless. • I’m memorizing the perform of the score I sonata to hope someday. • Brillig and, slithy and the toves • Wabe gimble in the gyre and did… • Note: just because we can say an infinite number of things, we can’t just say anything…
Technical Terminology • The set of rules that we know for creating sentences in a language is the grammar of that language. • The rules of grammar that we know are very abstract. (patterns of patterns) • Strings of words which do not adhere to these rules are ungrammatical. • Q: If these rules are so abstract, how did we figure out what they are? • How do we learn language?
Beneath the Surface • Note: we learn the language that we hear as we grow up, but… • We never hear the rules. • We can only learn from examples. • Our knowledge of language is sub-conscious. • Analogy: driving a car. • This knowledge is difficult to characterize. • (It is not explicitly taught to us.)
How is that possible? • Theory: language acquisition is so hard that we can’t do it by just observing other language users. • (we need help) • Claim: every human being has a “Language Acquisition Device” (LAD) • LAD = innate knowledge of language. • The LAD helps us learn language as we grow up. • Interacts with experience.
Predictions • The LAD theory makes some important predictions. • Universal Grammar (UG) • All languages should share certain features in common • …due to the workings of LAD. • A basic example: • All languages have nouns and verbs. 2. Poverty of the Stimulus • There should be properties of language that people “know” without ever having experienced them.
A More Complicated Example • How do you turn the following sentence into a yes/no question? • The boy who is sleeping is dreaming of a new car. • = Is the boy who is sleeping dreaming of a new car? • Not: *Is the boy who sleeping is dreaming of a new car? • “The boy” is linked to the second “is”. • Kids understand this connection without ever being taught about the link. • They never form the question the wrong way. • Think: baby turtles crawling towards the ocean.
Recursion • Recursion = another universal property of language? • which is unique to humans? • (Noam Chomsky thinks so.) • Remember, recursion = • involving a procedure that can refer to itself. • Ex: an English sentence may consist of: • [Noun] [verbs] that [sentence]. • With this rule, we can make sentences like: • Jean knows that Charlie said that Sue suspects that Bill thinks that Beth is a genius. • Sentences like this could be infinitely long…
Limited Infinities • However: there are limitations on how much we can remember. • This means that a sentence like: “I don’t know if Ross suspects that Monika thinks that Chandler hopes that Joey supposably believes that Phoebe heard that…” • couldn’t really go on forever. • Check out another kind of recursion: • The boy scared Mary. • The boy that the dog bit scared Mary. • How about: • The boy that the dog that the cat scratched bit scared Mary. (?!?)
Competence vs. Performance • An important distinction: • Linguistic Competence: • What a (native) speaker knows about a language. • Linguistic Performance: • How language is actually used in speech production and comprehension. • Word strings that are ungrammatical violate the rules of linguistic competence. • Other strings are impossible to say (or understand) because of performance limitations.
Performance Problems • Note: it is not impossible for native speakers of a language to make mistakes. • Ex.: slips of the tongue. • You have hissed all my mystery lectures. • = You have missed all my history lectures. • My wife made me some banana bed yesterday. • = My wife made me some banana bread yesterday. • Stammering, pauses, hesitations. • What matters (for grammar) is not what you actually do so much as what you think about what you do.
