  1. Presentation at the international conference: “Language Acquisition – comparative perspectives”, Homage to Clive Perdue December 5-6 2008, University of Paris 8

  2. L1 or L2 acquisition? Development of finiteness in adult L2, in young children (2L1) and in bilingual children (cL2) Suzanne Schlyter, Lund University In collaboration with Jonas Granfeldt, Lund University and Maria Kihlstedt, Paris X

  3. Structure of the speech • Introduction • Part I: adult L2 acquisition • Part II: first language (L1) acquisition • Part III: child L2 acquisition • Part IV: Discussion • Working Hypothesis: Those children who have acquired INFL+COMP before the L2 acquisition starts, will develop L2 French like adult L2 learners

  4. Why finiteness? • Central for the syntactic development – the I(NFL) category

  5. CP’ CP Spec IP’ C IP Spec VP’ I VP Spec Illustration - Syntactic structure V DP - que Pierre a t cassé la voiture

  6. Different positions on acquisition of finiteness and syntactic structure • A) Structure building: • L1 and L2, initial stages: only lexical elements (only VP, no INFL) (Perdue, Jordens, Hawkins, Myles …) • B) Complete syntactic representation in L1 and L2 from initial stages (L1: e.g. Wexler ) • > adL2 learners have access to INFL, COMP etc from start (White 2003); lack of finite marking in L2 is a superficial problem (Missing Surface Inflection) (Lardière, Prevost, …) • C) Structure building in L1, complete syntax in L2 (Granfeldt 2003, Schlyter 2005) Possibly syntactic growth = cognitive growth (Schlyter 2008)

  7. Meisel (2006, 2007, 2008) :(2)L1 vs adL2 • Fundamental difference L1-L2, only L1 UG-guided >> Critical Period • ”The FDH (…) enables us to make specific claims ablut the grammatical domains in which L2 is expected to differ from (2)L1” • (2)L1: on Subj-Verb Agr never errors (i.e. always je prends, never *je prendre etc)

  8. Marking of finiteness in FRENCHin children and adults • Subject clitic as ’prefix’ je mets / il marche • Difference finite – nonfinite forms je mange / j’ai mangé il prend / il va prendre

  9. PART IADULT SECOND LANGUAGE ACQUISITION adL2

  10. adL2 – adult second lg acquisition • Finite verb forms – a well known difficulty (ESF program, Prévost & White 2000, Herschensohn 2001, Schlyter 2004, Schlyter & Bartning 2005 etc) • (Prévost 2008): finite forms like il boit and non-finite verb forms in finite contexts: *il prendre des vêtements / *nous faire la cuisine • Proportion nonfinite verbs in finite contexts: ESF data Abdelmalek 24%, Zahra 22% • Prevost adL2 data: On all verbs: 27-2.5, 32-1.3, 15-0.7, 9-0.0% with growing stage. On lexical verbs only: 39-3.4, 54-2.6, 27-1.5, 15-0.0

  11. Swedish-French adL2 • Schlyter 2004: *je comprendre, la dame comprendre ‘I understand-INF, the lady understand-INF’ *je ne connaître pas ‘I NEG know-INF NEG’ *eh quand on voir français eh … ‘eh when one see-INF French eh’ >> If V+Neg then IP; if CP then IP >> Finiteness in syntactic sense is present – still nonfinite verbs

  12. Schlyter & Bartning 2005nonfinite verbs forms in adL2 • Initial stages (Stades 1 à 2, <9 months exposition): • Corpus Lund (Schlyter): • nonfinite forms 34% (of lexical verbs) • (= 64% finite forms) • Corpus InterFra (Bartning) • Nonfinite forms 22% (=78% finite f) • Thomas, A. (forthc) ca 50% • Advanced stages (from Stage 4 B&S): • practically NO nonfinite forms (cf. Prévost 2008 ’High Intermediate’)

  13. AdL2:Formes finies/non-finies, corpus Lund

  14. AdL2: Formes finies/non-finies dans 3 groupes d’InterFra

  15. Summary adult L2 acq (Sw>Fr) • Many nonfinite forms in finite contexts • Simultaneously AUX, MOD and SUBJUNCTIONS (=INFL, COMP), also in very early stages • Later: development towards correct finiteness • >> access to INFL from start

  16. PART II(BILINGUAL) FIRST LANGUAGE ACQUISITION (2)L1

  17. (2)L1 – first lg acquisition of finiteness in French • Initial stage without marking of finiteness pleure, le bébé‘ weeps, the baby’ • Soon complete marking without errors, correct syntax, evidence for acq of INFL (Pierce 1992, Meisel 1994, Schlyter 2004, etc) j’ai trouvé! ’I (have) found! n'aime pas celle-là’like not (=don’t like) that one’ • NEVER nonfinite forms after scl (like *je aimer, *il boire etc.)

  18. 2L1 Swedish – French children • Children growing up with Swedish and French (Schlyter 1993, 2004, 2005, Granfeldt 2003 etc.) • Next slide: Occ of subject + nonfinite form (like *il prendre, *je boire ) vs scl+V, in early stages (on ca 2600 utterances) • Result: NO subj-clitic+Nonfinite form

  19. Illustration: the verb ”donner” at different ages:

  20. Summary 2L1 acquisition (Sw+Fr) • Initially no evidence for INFL • Later, evidence for INFL: Scl+finite verbs, aux, mod (PC, FutPr) • >> Structure building • No incorrect use of scl+nonfinite forms

  21. PART IIICHILD SECOND LANGUAGE ACQUISITION chL2

  22. Why interesting? • Bilingual daycare, bilingual schools • The age factor • If Critical Period, when does it stop? puberty (Lenneberg); 6-7 ys (Rottweiler & Kroffke, Tracy & Thoma); 3-4 ys (Meisel, Unsworth). Depends on phenomena? on language? • If gradual decline (Montrul 2008), what declines?

  23. Previous studies on chL2 French • Meisel (to appear), children AO 3-4 years: Many have nonfinite forms >> = adL2 • Prévost 2004, children Kenny, Greg: Nonfinite forms like in L1 acq • Prévost 2008, same children: Few nonfinite forms (2.2 – 5.7%) >> = L1 >> contradictions!

  24. Present study:(Swedish >) French Child L2 • Children: RACHEL, PATRICK, VIOLA, VALENTINA, HANNES, from LFSL Stockholm (see Granfeldt, Schlyter & Kihlstedt 2007) • L1 Swedish, L2 French • Age of Onset 3;4 to 6;6 years • Levels defined in Mean Length of Utterance (MLU) and VocD/10:

  25. Development cL2 children - MLU + VocD/10(Arlette 2L1), Rachel, Patrick, Viola, Hannes, Valentine

  26. Nonfinite forms in cL2 from very early Patrick 6;1 years, input 7 m *INV: regarde, qu+est+ce+qu' elle fait avec la fleur ? ‘look what she does with the flower’ *CHI: il [/] il [/] il &pernde[= peint] . ‘he he he paint.INF’ Hannes 7;1 ys, input 7 m *CHI: et le chien qui &oua [?= voit] et [/] ‘and the dog who sees’ *CHI: et # il # prendre # le # chat # dans # euh ça . ‘and he take.INF the cat in that’

  27. Finite forms (of lexical/all verbs with subject) in cL2 *MLU sans ’oui’

  28. Verb forms in chL2, Swe - French

  29. Comparison between groupsSwedish > French in earliest stages • Nonfinite forms in finite contexts (Lexical Verbs) • adL2: around 30% below 8m exp • (2)L1: 0 % continously • chL2: around 23% at 7 m exp but rapidly reach 0% >> these chL2 more like adL2 than L1

  30. PART IVDISCUSSION

  31. Previous proposals for chL2 • Meisel: Fundamental Difference Hypothesis, Critical Period for grammar ends ca 3-4 years, then chL2 (French) = AdL2

  32. Previous proposals for adL2 acq • adL2 learners have acquired INFL, COMP etc through their L1, and have access to them in L2 (Schwartz, White,…) • Cf Perdue fortc • [les apprenants adultes] maîtrisent la manière dont la finitude est exprimée dans leur L1 et leur tâche d'apprentissage consiste (principalement) à découvrir de nouveaux moyens linguistiques pour exprimer ce concept.

  33. Our proposal for cL2 (Granfeldt, Schlyter, Thomas) • We know that children acquire the entire syntactic structure at about 3 – 4 years, i.e. VP > INFL > COMP • HYP: Those children who have acquired INFL+COMP before the L2 acquisition starts, will develop L2 French like adult L2 learners – not because of age but because of previous development • These chL2 learners have access to the corresponding cognitive categories (Schlyter forthc) • chL2 or adL2 learners resort to default forms in the L2 to express these functional / cognitive categories (Thomas forthc)
