Li/Lt6 Phonology and Morphology Lecture 1 Phonemes and abstract representations Today’s topics Two theories of mind Evidence for abstract mental representations Competence vs performance Priming Phonological alternations Evidence for phonemes Neutralization Language games Speech errors Loanword phonology and L2 transfer Orthography Perception Discrimination tasks Two theories of mind rationalist reductionist learning that learning to whole > sum of parts WYSIWIG abstract, multi-level concrete, surface level only symbol-manipulating rules and constraints connectionist network + statistical knowledge Turing machine switch network categorical, symbolic gradient, numerical The reductionist position Popular lay intuition that we store and manipulate surface forms Priming effects by individual voice “Once we introduce mechanisms for describing word-word correspondences into the grammar, it may be possible to dispense with underlying representations altogether (see proposals by Burzio 1998, Bybee 2001).” (Sumner 2003) connectionists Evidence for abstract URs Psychological reality: Sapir 1933 Basic points: speech sounds are stored in the mind as abstract categories (phonemes) These are not always identical to their surface manifestations ((allo)phones) Speakers think of language in terms of phonemes, not phones (i.e. phonemes have psychological reality) 1. 2. 3. oak tree maple tree Evidence: Spelling: Alex Thomas (Nootka) 1. • • writes <ħi, ħu> for [ħε, ħ] writes <C!> for 2 different things he was taught (T!, ’R) Intuitions 2. • NB Sapir needs external evidence to decide if the two forms he hears as identical are actually different phonetically • Southern Paiute • • • Tony says [pABAh] for ‘at the water’ Asked to divide the word into syllables, he says [pA ] [pAh] /p t k/ [β r γ] / V _; no /β r γ/ Sarcee • John Whitney feels that dìníh ‘it makes a sound’ has a final /t/, whereas dìníh ‘this one’ does not (cf. dìníth - í ‘the one who…’) TREE TIN k! L1 competence : performance “by the time infants are starting productive use of language they can already discriminate almost all of the phonological contrasts of their native language. While they cannot yet produce adult-like forms, they appear, in many respects, to have adult-like representations, which are reflected, among other things, in their vociferous rejections of adult imitations of their phonologically impoverished productions” (Faber and Best 1994:266-7) Did you say TINk? “Preferential Looking” paradigm (Hirsh-Pasek and Golinkoff 1993) • 19-month old infants’ comprehension of sentence like “Big Bird is hugging Cookie Monster. Where is Big Bird hugging Cookie Monster?” • Infants (who can’t speak yet) looked longer at correct video Cruttenden 1985 No!! competence vs. performance intoxicated speech of the captain of the Exxon Valdez (Johnson, Pisoni, and Bernacki 1990) Observed effects: • misarticulation of /r/ and /l/ • final devoicing • Deaffrication Performance problem, not different grammar attempts at producing adult [phεn] pen collected from a 15month-old child in a 30-minute period (Ferguson 1986): [mãə], [v], [dεdn], [hIn], [mbõ], [pHIn], [tHntHntHn], [bah], [dhau], [buã] competence vs. performance Bedore, Leonard, and Gandour 1994 4 yr old girl substitutes dental click for {s z S Z tS dZ} She can initially imitate the fricatives, but not produce them on her own After a short training session, she starts to produce [s] correctly She then immediately gets all the others right “the rapid rate of change observed in the child’s phonological system seems consistent with a phonological learning model in which the child has adult-like underlying phonological representations” (283) Priming Colloquial Dutch optionally neutralizes obstruent voicing with the clitic -der ‘her’ Do speakers respond faster to targets that match the voicing of a prime? Lexical decision task, with following sequence of events: 1. 2. 3. PRIME TARGET DECISION (verb+clitic construction) (verbal infinitive or nonword) (is the target a legitimate word of Dutch?) Results /ık kœs der/ ‘I kiss her’ [ık kœzdər] ~ [ık kœstər] /ık kiz der/ ‘I kiss her’ [ık kizdər] ~ [ık kistər] Responses were faster when voicing of prime corresponded to voicing of UR Conclusion Both variants of a verb are not stored in the lexicon Jongman, Allard. 2004.

Japanese g~ŋ and rendaku (Ito and Mester 2003) Rendaku: C [+voi] / ]+[ __ X] Lyman’s Law: X does not contain [+voi, -son] taba ‘bundle’ satsu+taba ‘wad of bills’ (*satsu-daba) g-weakening: non-initial /g/ [ŋ] kami-kaze vs. ori-gami [gai+jiN] ‘foreigner’ [koku+ŋai] ‘abroad’ Rule interaction R feeds GW: /ori+kami/ [oriŋami] R counterfeeds GW: /saka+toge/ ‘reverse thorn/ [sakatoŋe] If GW preceded R it would change g to ŋ and thereby feed R, resulting in *sakadoŋe Evidence for abstract phonemes Phonemes are also abstractions Ambiguity: German devoicing Rad Rat nom. [ At] gen. [Ads] [Ats] [] = voiced uvular fricative cf. French, Hebrew Perception Categorical perception: VOT Categorization functions for synthetic stimuli ranging from [b] to [p]. Open circles indicate the percent of times that each stimulus was perceived as [b], and the filled circles indicate the percent of times that each stimulus was perceived as [p].

Delattre, Liberman, & Cooper (1955) JASA 27, 769-773 Phonemes vs. allophones t : th in English (allophonic) vs. Thai (phonemic) Speakers produce consistent and finely controlled distinctions between allophones When measured experimentally, subjects typically distinguish allophones at above chance levels, but much less easily and well than phoneme pairs • for aspiration in English, see Pegg & Werker 1997, Whalen et al. 1997, Utman et al. 2000, Jones 2001 L2 transfer Phoneme vs. allophone Phonemes can distinguish meaning (flight : fright) Allophones don’t Orthography Phonological mediation In semantic disambiguation tasks, the phonology of a word interfered with the disambiguation process even when the reader had access to its semantic representations (Van Orden 1987). reader was presented with IS THIS A FLOWER? followed by the presentation of ROWS Correct response accuracy for such sentence-target pair was significantly lower when the targets shared a phonological representation with a word neighbor that semantically fit the question (i.e., ROSE). when the subject had the ability to resolve the task with the correct answer (NO) phonological information intervened. Letter priming Lee and Turvey 2003 forms with deleted silent letters (SALM, COLUM) prime better than forms with deleted pronounced letters (COUSI) Conclusion: phonological representations are activated during visual word recognition. Speech errors Types of speech errors Language games Backwards English Cowan & Leavitt 1992 study of one woman Example: garage [graž] reversed as [žarg] Evidence that she reverses phonemes (rather than letters): • 1. no silent letters pronounced in reverse forms • 2. homographs were always pronounced differently (two <g>'s in garage) Not functioning as reversed tape recorders: • Compound units (diphthongs and affricates) were consistently preserved as units rather than being reversed. • choice [tšojs] was reversed as [sojtš] (rather than *[sjošt]) Verlan Procedure Invert syllables (in polysyllabic words) • L’envers ‘the reverse’ → [verlan], femme ‘woman’ → meuf • Cf. Spanish Vesre, which inverts syllable order, e.g. muchacho → chochamu What to do with monosyllables? Include final optional schwa, if there is one moi [mwa] ‘me’ → ouam [wam] fou [fu] ‘crazy’ → ouf Viens chez ouam soir-ce y'a une teuf de ouf, je suis avec l'autre nasbo, j ai du sky et la race de beuh ‘Come to my place tonight there is a huge party, I'm with this hot chick, I've got some whiskey and a lot of weed’ teuf - fête ‘party’, nasbo = bonasse ‘hot chick’, sky = whiskey, beuh = herbe ‘weed’ Key for us: monosyllables inversion of phonemes Drop final vowel Conclusions Words are not acoustic signals, but rather abstract mental representations of language. Words in turn are composed of abstract phonemes, which are again abstract mental symbols rather than elements of the physical world. References Bedore, L., L. Leonard, and Jack Gandour. 1994.
