3 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

4 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

5 Why finiteness? Central for the syntactic development – the I(NFL) category

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

7 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)

8 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)

9 Marking of finiteness in FRENCH in 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

10 PART I ADULT SECOND LANGUAGE ACQUISITION adL2

11 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

12 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

13 Schlyter & Bartning 2005 nonfinite 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’)

14 AdL2: Formes finies/non-finies, corpus Lund Apprenants formes finies, % Moins de 9 mois d’exposition66% Groupe intermédiaire80% Plus de trois ans d’exposition dans le pays ; ou après l’école et un semestre d’université 94%

17 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

18 PART II (BILINGUAL) FIRST LANGUAGE ACQUISITION (2)L1

19 (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.)

20 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

23 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

24 PART III CHILD SECOND LANGUAGE ACQUISITION chL2

25 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?

26 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!

33 PART IV DISCUSSION

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

35 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.

36 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)
