    Slide 1:Defining the Site of Linguistic Variation

    William Labov, University of Pennsylvania Workshop on Locating Variability: Formal Approaches UMassAmherst April 24-26, 2008

    Slide 2:Variable AAVE copula as an insertion from a competing grammar

    AAVE 0 Std Eng iz z He is talking about that Full /iz/ He’s talking about that Contracted /z/ He talking about that Absent /0/

    Slide 3:Variable AAVE copula and auxiliary as the result of successive contraction and deletion of an underlying form /iz/

    Lexical entry v => /iz/ Stress assignment [+str] => [-str] Vowel reduction /iz/ => /´z/ Contraction: /´z/ => (z) Deletion: /z/ => (0)  ´z  ´z  z  0 Contraction Deletion  z

    Slide 4:The basic syntactic regularity

    AAVE copula and auxiliary can be deleted or contracted only in those syntactic positions where other dialects can have contraction.

    Slide 5:Phonotactic effects on contraction and deletion

    Jo is talking Jen is talking CVVC CVC Jo’s talking Jen’s talking CVC CVCC Jo talking Jen talking CVC CVC Contraction Deletion CV subject CVC subject

    Slide 6:Phonetic conditioning of contraction and deletion for two adolescent groups in South Harlem [from Labov, Cohen Robins and Lewis 1968]

    Cobras Jets K__ V__ K__ V__

    Slide 7:Possible phonetic conditioning of AAVE copula as an insertion from a competing grammar

    AAVE 0 Std Eng iz z He is talking about that Full /iz/ He’s talking about that Contracted /z/ He talking about that Absent 0 Jen talking Jo talking

    Slide 8:A clear case for an invariant underlying form: Variable past tense {d} in AAVE

    Absence primarily in complex codas. Absence is strongly conditioned by the initial segment of the following word.

    Slide 9:Internal constraints on -t,d deletion for 11 speakers of AAVE [Table 3.7 of 3288 Report, Labov, Cohen, Robins & Lewis 1968]

    KD = complex codas mm = monomorphemic VD = simple codas am = ambiguous p = past

    Slide 10:Variable past tense {d} in AAVE

    Absent primarily in complex codas. Strongly conditioned by the initial segment of the following word. Phonological conditioning regular across the speech community.

    Slide 11:Phonological conditioning of -t,d deletion for AA youth and adults in Harlem, 1968

    Group Single Group Single Monomorphemic Past tense Inwood whites (8)

    Slide 12:Phonological and grammatical factors controlling -t,d deletion for African American speakers in Pacoima CA --from Baugh 1979

    Preceding segment Following segment Grammatical category

    Slide 13:Phonological and grammatical conditioning of -t,d deletion in spontaneous speech of 58 African American struggling readers from Philadelphia, Atlanta and California

    Preceding segment No. pre-ceding segments Grammatical status Voicing Voicing agreement Stress Following segment

    Slide 14:Variable past tense {d} in AAVE

    Absent primarily in complex codas. Strongly conditioned by the initial segment of the following word. Phonological conditioning regular across the speech community. No hypercorrection: past tense {d} is never found in non-past contexts.

    Slide 15:A clear case of no underlying form: variable verbal {s} in AAVE

    Absent in both simple and complex codas. Not conditioned by the phonetic environment.

    Slide 16:Absence of phonological conditioning off verbal {s} in the spontaneous speech of 58 African-American struggling readers, 2001

    Preceding segment Following segment Verb Pronoun/ Noun phrase Region Grade Gender

    Slide 17:Absence of phonological conditioning of verbal /s/ for AA groups in South Harlem [from Labov, Cohen, Robins & Lewis 1968]

    Group Single Group Single Monomorphemic Verbal suffix So. WC

    Slide 18:Variable verbal {s} in AAVE

    Absent in both simple and complex codas. Not conditioned by the phonetic environment Extensive hypercorrection: {s} is inserted in many syntactic contexts besides third singular present.

    I trusts my friend. [14, Jet, #527] My brothers plays in it. [11, T-Birds, #372] He knows what he gots to do. [13, Jets, #602] I gets high every mornin’ before I go to school. [16, Jets, #667] . . . somebody get hurts. [39, NYC, #802] He can goes out. [13, T-Birds, #375] You don’t belongs with them. [52, Fla., A#663] I don’t know how to gets no girls. [13, Jets, #535] He’s gots to be nasty! [13, Jets, #535] He just wantsa gets off. . . [11, T-Birds, #381]

    Slide 19:Irregular distribution of verbal {s} in AAVE

    Slide 20:Variable verbal {s} in AAVE

    Absent in both simple and complex codas. Not conditioned by the phonetic environment Extensive hypercorrection: {s} is inserted ind many syntactic contexts. Learnability: great difficulty in recognition and acquisition of use.

    Slide 21:A test of the capacity to derive number information from verbal {s}

    ? ?

    Slide 22:Recognition of meaning of inflections by second graders in Harlem before and after training [from Torrey 1965]

    Slide 23:The AAVE possessive

    John house This house is John’s my sister house This house is my sister’s my book This book is mines. POS => 0 / __ NP => /z/

    Slide 24:Absence of attributive possessive {s} in spontaneous speech of struggling readers, California schools, 2002-2003

    Slide 39:Phonological effects on morphological selection

    sharpen atomize lighten concretize darken finalize heighten civilize whiten fantasize roughen cannibalize shorten slenderize

    Slide 40:Phonological derivation of allomorphs of English articles

    the /Diy/ => D´ / [-str] __ # [+cons] +Det an /ćn/ => ´n / [-str] n => 0  / ´ __ #[+cons] +Det under-lying form out-put form

    Slide 41:The Asymmetry of Variation Principle

    Morphological variation is not associated with postlexical phonetic variation; postlexical phonetic conditioning is associated with an invariant vocabulary item.

    What is a reading error? In responding to oral reading, how can we distinguish between differences in pronunciation and mistakes in reading?

    Slide 42:Further differentiation of past-tense {d} and verbal {s} from answers to a question raised in research on raising reading levels, 2001-2006

    Slide 43:Clear errors and potential errors

    Clear errors: selection of wrong words: Reader: Tyreke J., 8 years old, 3rd grade, African American, Philadelphia. Text: My blood began to boil. Reading: My boat began to bill. Potential error: failure to articulate a past tense morpheme: Reader: Filores J., 8 years old, 3rd grade, African American, Philadelphia. Text: I played it cool and took a sip of my coke. Reading: I play it cool and took a sip of my coke

    Slide 44:Potential past tense errors

    Absence of the grammatical suffix {d} in final homovoiced clusters: dined read as /dayn/ = dine? rolled read as /rowl/ = roll, role? missed read as /mis/ = miss? laughed read as /lćf/ = laugh?

    Slide 45:The semantic shadow hypothesis

    Failure to identify the intended meaning of a given element in the text will increase the probability of errors in the remainder of the clause.

    Slide 46:Frequency of following errors for clear errors and correct reading by dialect type, 2001-2

    Slide 47:Frequency of following errors for clear errors and correct reading by dialect type, 2001-2

    Mean error rate, all words = .133

    Slide 48:Calculation of proportion of following errors for five types of potential errors

    Slide 49:Frequency of following errors for clear errors, potential errors and correct reading by dialect type [N=567]

    Slide 50:Ethnic/language groups in the 2001-2006 study

    Philadelphia California African American (A) 112 79 Euro American (W) 62 44 Latinos who learned to read in English first (E) 57 83 Latinos who learned to read in Spanish first (S) 51 89

    Slide 51:Frequency of following errors for clear errors, potential errors and correct readings by dialect type for 58 African American readers

    Slide 52:Frequency of following errors for clear errors, potential errors and correct readings by dialect type for African American and Latino (S) readers [N=238]

    clear errors identical correct reading identical past {d} idifferent

    Slide 53:Likelihood of potential errors being reading errors by dialect type and ethnic/language group, 2001-02 [N=722].

    not significantly different from correct reading, significantly different from errors significantly different from correct reading, not significantly different from errors xxx significantly different from correct reading and errors xxx not significantly different from correct reading and errors E = learned to read in English first S = learned to read in Spanish first xxx xxx = correct reading ?correct reading
