Title: Questions for the Week
1Questions for the Week
2Questions
- Can (all?) modifications in foreign language
production be explained as transfer from the
native language grammar? Does universal
markedness play a role? Language-independent
phonetic factors?
3Questions, continued
- Why are some foreign structures mastered more
quickly than other (equally new) structures? - Japanese chiimu team
- shiifuudo seafood
- shiitibanku Citibank
- never siichibanku
4Questions, continued
- What determines how illegal structures are
modified? - Christmas
- Japanese kurisumasu
- Hawaiian kalikimaki
- Maori kirihimete
- Samoan kilisimasi
5Questions, continued
- How much of foreign language modification is a
result of misperception? Of misproduction? And
how can we tell?
6For example
- Does a Japanese speaker who pronounces
Christmas as kurisumasu actually HEAR the
English pronunciation as kurisumasu? - English Japanese
- kr?sm?s kurisumasu ?
7Grammar
- Acoustic Form
- perception
(e.g.,Boersma 1998, V Pater 2004) - Phonological Representation gt UR gt
- production
- V
- Phonetic Representation
8(1) Modification Misproduction (e.g., Paradis
and LaCharité 1997)
- Adapters correctly identify FL phonemes, map to
UR. - Production grammar repairs underlying
representations to conform to native language
constraints.
9Problems with claim that all modification
misproduction
- Modification may be influenced by subphonemic
information. - e.g., Kang 2003 Vowels in Korean loans may be
inserted even after legal stop codas. Likelihood
of insertion is related to likelihood of the
release of that stop in the English source.
10(2) ModificationMisperception (e.g., Peperkamp
Dupoux 2003)
- Japanese listeners hear ebzo as ebuzo.
- Cf. Dupoux et al. 1999, Dehaene-Lambertz et al.
2000, Jacquemot et al. 2003 for experimental
support.
11Not a lexical effect Dupoux et al. 2001
- Lexical decision task
- nonword stimuli real words
- sokdo sokudo speed
- mikdo mikado emperor
- Sokdo classified as real words, mikdo as nonwords
12Problems with claim that all adaptation
misperception
- Some perception is accurate (e.g. Berent et al.
syllable-counting experiments) - Still must explain direction of misperception
why kurisumasu and not kilihimete, etc.?
13(3) Modification misproduction, but guided by
phonetic similarity
- P-map Hypothesis (Steriade 2001, etc.) Learners
perceive FL phonological forms accurately, but
the production grammar contains constraints that
enforce phonetic similarity between UR and PR.
14Problem with claim that adaptation production
perceptual similarity
- Even after adding perceptual similarity
constraints to the production grammar, we are
left with a residue of cases that must be
analyzed as misperception (inaccurate mapping
from foreign acoustic form to adapters UR).
15(4) Dual-level model(e.g., Silverman 1992, Yip
2002, 2006)
- Listeners misperceive less salient features
(partially inaccurate mapping to UR). - Listeners accurately perceive more salient
features, but production grammar may still make
changes in mapping from UR to PR.
16Problem with Dual-Level Model of adaptation
- Lack of clear criteria for deciding whether a
particular modification pattern is a function of - Misperception
- Misproduction
17Questions, continued
- If foreign forms are misperceived, at what level
of processing does this misperception occur?
18Questions, continued
- To what extent is perception determined by early
language experience? - Is there a neural commitment to L1 contrasts?
19Questions, continued
- Can formal theories of grammar shed light on
foreign language production patterns?
20One Potential Criterion for perception vs.
production Learnability
- OT aims to define
- What is a possible grammar (set of ranked
constraints). - What is a learnable grammar (rankings can be
derived from input data, using an error-driven
algorithm).
21- Modification patterns that cannot be described in
terms of learnable production grammar rankings
must be a function of - Misperception, or
- Other factors (frequency, timeline of exposure to
FL, etc.).
22Today
- Models of Acquisition First Language and Foreign
Languages
23To build a phonological grammar, children must
learn
- What is linguistically significant in the target
language (possible contrasts). - What is legal in the target language (possible
structures, phonotactics). - Morphemes and allomorphs (alternations).
24Stages of Acquisition (e.g., Hayes 2004)
- Birth to 6 months can distinguish all possible
phoneme contrasts. - 6-8 months begin to form sound categories
(perceptual magnet effects). - 8-10 months begin to form a lexicon begin to
learn phoneme categories of ambient language. - Older begin to learn morphological processes,
alternations.
25Perception vs. Production Common Assumptions
- Children generally perceive L1 accurately.
- Many of childrens simplifications of adult forms
are due to misproduction rather than
misperception.
26Example One Argument for Accurate Perception
- Gnanadesikan (2004) Productions by G, 27-33
months
27Simplification of onset clusters
- G Adult
- a. s-stop
- gaj skaj sky
- b?w sp?l spill
- d? star star
- b. s-sonorant
- so sno snow
- sip slip sleep
28- s-obstruent gt obstruent (sky gt gaj)
- s-sonorant gt s (snow gt so)
- Onset C of lowest sonority is maintained.
29Clusters containing labial r or w
- G Adult
- a. pi tri tree
- b. b?k dr??k drink
- c. paj kraj cry
- d. bep grep grape
- e. pajt kwajt quite
- f. f?'D? sw?'D? sweater
- g. f?w sm?l smell
30- pr, tr, kr, kw gt p (tree gt pi)
- br, dr, gr gt b (grape gt bep)
- sm, sw gt f (smell gt f?w
- Labial articulation is always maintained, though
labial segment may disappear.
31Gs perception bep grape
- Does G actually hear (e.g.) gr as b?
32Replacement of initial unstressed syllable
- G Adult
- a. fitén? k?ntén?r container
- b. fig?'Di sp?g?'Di spaghetti
- c. fib?'k? r?b?'k? Rebecca
- d. fimáwo t?máro tomorrow
33Accurate perception?
- Does G actually hear the material in the initial
syllable replaced by fi?
34Preference for obstruent onsets
- G Adult
- a. fikál? koál? koala
- b. fibún b?lún balloon
- c. fipís p?lís police
- d. fibó b?ló below
35- When the syllable following fi begins with a
high sonority onset (liquid, glide) or no onset,
the word-initial onset is recruited - balloon gt fibún
36Gs Perception
- Although G replaces initial unstressed syllables
with fi, she apparently does hear the segmental
content (at least the onset) of these
syllables--because features of that onset may
appear elsewhere in the word.
37- fib?j? g?r?l? gorilla
- It seems unlikely that G hears gr in gorilla
as b, since G seems to hear that gorilla
contains 3 syllables.
38Gnanadesikans analysis
- Gs modifications result from a grammar that
differs from the adult grammar. - These modfications result from a preference for
less marked surface structures. - Each feature of Gs grammar is attested in some
adult NL grammar.
39OT is intended as a theory of
- typologydefines possible grammars.
- learnability--defines how a grammar is learned
from exposure to a set of data.
40Architecture of the theory
- Markedness constraints (or well-formedness
constraints, structural constraints) define
possible surface structures. - e.g. NoCoda, NoComplexOnset
41- Faithfulness constraints define possible mappings
from lexical representations to surface
representations. - e.g. Dep (no insertion), Max (no deletion)
42Ranking Tableau MgtgtF
/sno/ NoComplexOnset (Markedness) Max (no deletion) (Faithfulness)
a. sno !
gt b. so
43Ranking Tableau FgtgtM
/sno/ Max (no deletion) (Faithfulness) NoComplexOnset (Markedness)
gt a. sno
b. so !
44Rankings determine surface structures
- M gtgtF suppresses surface contrasts.
- NoComplexOnset gtgt Max
- /so/ gt so
- /sno/ gt so
- (no CV-CCV contrast is possible)
45- F gtgt M preserves lexical contrasts.
- Max gtgt NoComplexOnset
- /so/ gt so
- /sno/ gt sno
- (CV-CCV contrast is possible)
46Rankings determine preferred repair
- Dep gtgt Max /sno/ gt so
- (deletion is preferred to insertion)
- Max gtgt Dep /sno/ gt sVno
- (insertion is preferred to deletion)
47Rankings determine
- Choice of deletion vs. insertion
- Which C is deleted (/sno/ gt so vs. no)
- Which V is inserted (/sno/ gt sino, sono, etc.)
48Assumptions (classical OT)
- Constraint set is universal.
- Rankings are language-specific.
- Each possible ranking defines a possible grammar.
49Classical OT model of First Language Acquisition
- Constraints are innate.
- Rankings must be learned.
50Corollary
- Each developing grammar (each stage of language
acquisition) must represent a possible human
grammar, since grammars differ only in ranking of
constraints.
51Parallels between Gs grammar and adult grammars
- onset simplification to lowest-sonority C gay
for sky, so for snow - Sanskrit reduplication pa-prach, tha-stha
52Coalescence of segments
- bep for 'grape', f?w for 'smell
- Navajo dx gt g, Luganda mu gt mw, Kirundi
tu gt tkw
53Preference for trochaic feet, aligned with left
edge fibún for balloon
- Fikkert 1994, Demuth 1996
- Dutch óxant (ólifant), ánd?, ánR? (andere),
- bál? (bal)
- Sesotho kolo (sekolo) school
- Kiche (word-final stress) lóm (jolóm) head
54Melodic overwriting fi
- Kolami pal-gil, kota-gita, maasur-giisur
- Chinese secret language may ka for ma, xway kwey
for xwey
55Child grammar possible adult grammar
- Each developing grammar should reflect some
possible constraint ranking.
56Question
- Is there an initial state/default constraint
ranking? - Answer from Gnanadesikan and others MgtgtF
57Arguments for Default MgtgtF
- 1. Childrens modifications are generally in the
direction of reduced markedness.
58Subset Problem (Angluin 1980, Baker 1979)
- 2. If children can only use positive evidence
(actual linguistic forms) in constructing a
grammar, they must begin with the most
restrictive grammar possibleotherwise their
grammars will overgenerate.
59Illustration
- Child C (for conservative) assumes MgtgtF
NoComplexOnset gtgt Faithfulness. - Child Cs grammar allows only CV syllables.
60- Child R (for reckless) assumes FgtgtM
- Faithfulness gtgt NoComplexOnset.
- Child Rs grammar allows both CV and CCV
syllables.
61If Child C (MgtgtF) is born to
- Hawaiian-speaking parents,
- Childs grammar adult grammar
- English-speaking parents,
- Childs grammar ? adult grammar, but no
worries--child gets positive evidence (CCV)
telling her to rerank constraints.
62If Child R (FgtgtM) is born to
- English-speaking parents,
- Childs grammar adult grammar
- Hawaiian-speaking parents,
- ? Childs grammar ? adult grammar, AND
- no positive evidence can ever trigger
- reranking.
63Learning is error-driven
- Default ranking MgtgtF.
- Other rankings (MgtgtM, FgtgtF) must be learned from
data.
64What is default for language contact situations?
- Presumably, the learner/adapter begins from the
NL rankings. - Therefore, adaptation/error patterns should be
explainable as either - transfer of NL rankings, or
- universal default rankings.
65Potential Problems in Language Contact Phonology
- 1. M gtgtM rankings (differential difficulty)
- NL bans 2 structures
- FL allows both structures
66- BUT learners/adapters master one structure more
easily. - e.g. Japanese shiitibanku (both ti and si are
illegal in Japanese).
672. FgtgtF rankings (differential repair)
- NL has no inputs with illegal structures, so no
evidence for repair preference - BUT learners/adapters adopt specific repairs,
- AND these repairs may vary across languages
(therefore not universal), - AND different repairs may be used within a single
language in different contexts.
68Dehu (Tryon 1970)
- a. Obstruent__Sonorant copy V
- peleit plate
- galas glas
- b. Obstruent__Obstruent default i
- sipö spur
- sipun spoon
693. Ranking Reversals
- Korean NL stopnasal gt nasal nasal
- /kukmul/ gt ku?mul soup
- But in SLA, Koreans often insert vowel
- /tegnal/ gt teg?nal (Hwang 2006).
70Proposal
- Where modification patterns would require a
grammar with unlearnable rankings, these patterns
have their source in factors such as - misperception
- frequency
- orthography
- time course of language contact
- etc.
