On how age affects L2 learning in natural and instructed settings Carmen Muñoz Universitat de Barcelona GALA ’07 University of Thessaloniki
C. Muñoz - Gala '07 Age effects “The earlier the better”
C. Muñoz - Gala '07 Opinions “ The bilingual children I have met over the years learnt their skills at a very young age. When a child arrives in school with no English they learn quickly. ” (British teacher; Enever, forthcoming) “ Children are learning language anyway and pick it up naturally ” (British teacher; Enever, forthcoming) “ The younger they are, the more they are like sponges, the more they absorb, the more they retain. ” (Spanish parent; Torras, Tragant & García,1997)
C. Muñoz - Gala '07... like a sponge young children “soak up” languages
C. Muñoz - Gala '07 Scientific facts? Critical Period Hypothesis (Lenneberg, 1967) “... after the critical period language acquisition may be impossible or incomplete ”
C. Muñoz - Gala '07 Multiple sensitive periods –Some variability in ages of onset and offset –Environmental influence –Different timings for pronunciation (age 6), morphosyntax (midteens), … Scientific facts?
C. Muñoz - Gala '07 Theoretical dimension A biologically determined period → an innate language-specific faculty A valid SLA theory needs to solve the problem of age-related outcomes (Long, 2007) Applied dimension When to begin FL teaching at schools? Theoretical and applied dimensions
C. Muñoz - Gala '07 This talk Point out asymmetries concerning age-effects in natural and instructed learning contexts. -SLA and FLA -Characteristics of FL learning settings -5 asymmetries -Conclusions
C. Muñoz - Gala '07 SLA vs. FLA SLA resembles the natural way young children learn their L1, i.e., by implicitly acquiring the language while attempting to use it in communicative contexts for real- world purposes Instructed FLA draws more on conscious learning, explicit focus on form, and controlled practice.
C. Muñoz - Gala '07 Foreign language settings 1. instruction is limited to 2-4 sessions of approx. 50 min. / week 2. exposure to the TL during those class periods may be limited both in source (mainly the teacher) and quantity 3. the TL is not the language of communication between peers 4. the teacher’ s oral fluency may be limited 5. the TL is not spoken outside the classroom
C. Muñoz - Gala '07 5 asymmetries 1. Age-related advantages 2. Age of acquisition 3. Ultimate attainment 4. Length of exposure 5. Learning mechanisms
C. Muñoz - Gala '07 Learning outcomes Instructed L2 settings? …. can we automatically generalize?!
C. Muñoz - Gala '07 Instructed FL learning. The BAF Project Explore age effects in a foreign language setting –at different points in time (short/long term defined by increments of instruction/exposure) –for different language abilities –mixed design including longitudinal data
C. Muñoz - Gala '07 Group A AO = 8 Group B AO = 11 Group C AO = 14 Group D AO = 18+ Time h. A1A1A1A1 AT = 10;9 N = 284 OSE = 165 B1 AT = 12;9 N = 286 OSE = 107 C1 AT= 15;9 N = 40 OSE= 40 D1 AT = 28;9 N = 91 OSE = 67 Time h. A2 A2 AT = 12;9 N = 278 OSE = 140 B2 AT = 14;9 N = 239 OSE = 99 C2 AT =17;9 N = 11 OSE= 11 D2 AT = 39;4 N = 43 OSE = 21 Time h. A3 AT = 16;8 N = 338 OSE = 61 B3 AT = 17;9 N = 296 OSE = 51 D3 AT = 41;7 N = 7 OSE = 3 Time h. A4 AT = 17;9 N = 155 OSE = 27 The BAF Project
C. Muñoz - Gala '07 The BAF Project Questionnaire: language (L1, L2, L3) use, motivation, strategies,... Measures: –cloze (L1, L2, L3) –dictation (L1, L2, L3) –grammar –composition: fluency, (lexical & grammatical) complexity, accuracy –listening comprehension –minimal pair discrimination –word imitation –oral interview: production and reception; vocabulary development –oral narrative: textual cohesion; vocabulary development; grammar –role-play –map task
C. Muñoz - Gala '07 General results: cross-sectional and longitudinal data T1: D1 > C1 > B1 > A1 T2:D2 > C2 > B2 > A2 T3: B3 > A3
C. Muñoz - Gala '07...late starters are more efficient Advantage not uniform with respect to: - phonetics/phonology - morphosyntax - listening comprehension Gap reduced when difference in age (and cognitive development) is reduced as well
C. Muñoz - Gala '07 Phonetics –Initial age of learning not conclusive determinant … (Fullana, 2006)
C. Muñoz - Gala '07 “Accented L2 input hypothesis” “ L2 learners will fail to perceive and produce L2 sounds accurately if they are not provided with adequate L2 phonetic input, regardless of their starting age of L2 learning.” (Flege, 1991)
C. Muñoz - Gala '07 Morphosyntax vs. Listening comprehension (from Muñoz, 2006)
C. Muñoz - Gala '07 Morphosyntax ES < LS Increase in morphosyntax gains around puberty years
C. Muñoz - Gala '07 In an instructed L2 learning setting do younger starters outperform older starters in the long-term?... in the long-term?
C. Muñoz - Gala '07... in the long-term? “… if the older learners’ advantage is mainly due to their superior cognitive development, no differences in proficiency are to be expected when differences in cognitive development also disappear with age.” (Muñoz, 2006: 34 )
C. Muñoz - Gala '07 …getting a clearer picture of age effects in a school setting …
C. Muñoz - Gala '07 Same amount of instruction different age at testing. BAF Project -Early starters < Late starters -In the long term, early starters may catch up but no long-term advantage > Late starters are more efficient learners
C. Muñoz - Gala '07 Different amount of instruction same age at testing -Early starters > Late starters in oral/aural skills -In the long term, late starters catch up to early starters in literacy skills Burstall (1975); Oller & Nagato (1974); Harley (1986); Swain & Lapkin (1986); Turnbull et al. (1998); …
C. Muñoz - Gala '07 Different amount of instruction same age at testing - When there is enough exposure, older starters show higher learning efficiency in literacy skills as well. - Are younger starters’ higher oral/aural skills an effect of their initial age of learning or of exposure/instruction? … Age effects or Time effects??
C. Muñoz - Gala '07 “… no explanation has yet been provided for why in school settings the additional time associated with an early headstart has not been found to provide more substantial long-term proficiency benefits.” (Harley, 1998)
C. Muñoz - Gala '07 Asymmetry 2: Age of acquisition Natural settings Age of acquisition = = beginning of significant exposure
C. Muñoz - Gala '07 Significant exposure “… to participate in social settings effectively dominated by the L2 ” (Stevens, 2006) = …learners are able to carry out a variety of speech acts over a wide range of situations and topics “... immersion in the L2 context ” (Birdsong, 2006)
C. Muñoz - Gala '07 Significant exposure? NO social settings dominated by L2 in which to participate learners are not able to carry out a variety of speech acts over a wide range of situations and topics NO immersion: 3-4 hours / week 1 hour / week? Instructed settings
C. Muñoz - Gala '07 Significant exposure? Previous instruction in home country? – No correlation found (Johnson & Newport, 1989, etc.) Exception (Urpunen, 2004) – Disregarded: ”insignificant” (White & Genesee, 1996)
C. Muñoz - Gala '07 Asymmetry 2: Initial point Instructed settings Age of acquisition = Beginning of insignificant exposure a valid index? point vs period
C. Muñoz - Gala '07 Asymmetry 3: Ultimate attainment UA = final product of L2 acquisition = +/- nativelikeness Final product entails cessation of learning that appears in spite of optimal learning conditions (including input that is neither quantitatively nor qualitatively limited). Han (2004); Han & Odlin (2006); Selinker & Lamendella (1979)..
C. Muñoz - Gala '07 Instructed settings The requirement of having optimal learning conditions (including input that is neither quantitatively nor qualitatively limited) is not fulfilled in foreign language learning. Asymmetry 3: Ultimate attainment
C. Muñoz - Gala '07 Natural settings: Length of time of residence → ultimate attainment in L2 (native-like) Snow (1983): 2 yrs > 5 yrs Slavoff & Johnson (1995): 3 yrs not enough Krashen et al. (1979): 5 yrs DeKeyser (2000): 10 yrs Asymmetry 4: Length of exposure
C. Muñoz - Gala '07 Asymmetry 4: length of exposure Instructed settings 10 years (14 h / day) = hours = weeks (4h / week) = 245 years …
C. Muñoz - Gala '07 Asymmetry 5: Learning mechanisms Natural settings “... automatic acquisition from mere exposure to a language may disappear after puberty …” (Lenneberg,1967: 176) “… between the ages of 6-7 and 16-17, everybody loses the mental equipment required for the implicit induction of the abstract patterns underlying a human language.” (DeKeyser, 2000)
C. Muñoz - Gala '07 “ the implicit acquisition processes … require massive amounts of input, that only a total immersion program can provide, not a program with a few hours of foreign language per week.” (DeKeyser, 2000) Implicit acquisition
C. Muñoz - Gala '07 Asymmetry 5: implicit vs. explicit Natural settings provide enough comprehensible input to make form-meaning mappings... suited for younger learners Instructed settings provide explicit instruction (“short-cuts”)… suited for older learners, but do not provide the amount and intensity of input necessary for implicit learning.
C. Muñoz - Gala '07 Conclusions
C. Muñoz - Gala '07 Contribution of studies in natural contexts The earlier the better
C. Muñoz - Gala '07 Overgeneralization The earlier the better in any situation and independently of learning conditions (exposure, pedagogical, etc.)
C. Muñoz - Gala '07 Contribution of studies in instructed contexts... provided it is associated with enough significant exposure - distributed intensively - and with opportunities for participating in a variety of L2 social contexts The earlier may be the better...
C. Muñoz - Gala '07... children need water like a sponge!
C. Muñoz - Gala '07 Research agenda To determine the amount of input required for an early start to be effective in promoting language learning To focus on the relative gains of different-age pupils with different types of time distribution The distinction between short-term and long- term benefits of starting at different ages The comparative study of the learning rate of different-age learners to inform educators about what to expect after n years of FL instruction from different-age learners (Muñoz, 2008)
