Types of L2 morphosyntactic knowledge that can and cannot be observed in learner corpora
1 like2,143 views
This document discusses the types of L2 morphosyntactic knowledge observable in learner corpora and the limitations of such data in Second Language Acquisition (SLA) research. It differentiates between explicit, implicit, declarative, and procedural knowledge and highlights the strengths and weaknesses of using learner corpora for exploring linguistic phenomena. Additionally, it calls for more detailed analyses and collaboration between corpus linguists and SLA researchers to enhance understanding of L2 acquisition processes.

- 2. About me
- 3. • Interests: Second language acquisition (SLA) • SLA is the scholarly field of inquiry that investigates the human capacity to learn languages other than the first, during late childhood, adolescence or adulthood, and once their first language or languages have been acquired. (Ortega, 2009, pp. 1–2) About me
- 4. • Goal and scope of SLA research • (SLA) seeks to understand universal, individual and social forces that influence what gets acquired, how fast, and how well, by different people under different learning circumstances. (Ortega, 2009, p. 10) Goal & scope what gets acquired
- 8. Acquired • Two types of L2 knowledge • explicit vs. implicit (e.g., Ellis et al., 2009) • declarative vs. procedural (e.g., Dekeyser, 2007) • learned vs. acquired (e.g., Krashen, 1981) Two types of L2 knowledge
- 9. Two types of L2 knowledge • Explicit knowledge is“the conscious awareness of what a language or language in general consists of and/or of the roles that it plays in human life”(Ellis, 2004, p. 229). • Implicit knowledge is intuitive and procedural, variable but systematic, usually accessed by means of automatic processing and during fluent performance, and not verbalizable. (Gutiérrez, 2013, p. 424)
- 10. Two types of L2 knowledge • Theories of L2 acquisition… seek to explain how learners develop implicit knowledge, not explicit knowledge…. L2 acquisition, then, is equated with the development of implicit knowledge. (Ellis, 2006, pp. 434–435)
- 11. Learner corpora
- 12. • Learner corpora can be defined as systematic computerized collection of texts produced by learners (Nesselhauf, 2005, p. 40). Learner corpora

W: Written, S: Spoken This is not to be meant as an exhaustive list. Available corpora
- 14. • The ICNALE Written • Two topics: Part-time jobs & smoking • 20–40 minutes per essay • No reference allowed • 200–300 words each • Spelling check required (MS Word) http://language.sakura.ne.jp/icnale/instruction.html Data collection
- 15. • For the purposes of fundamental SLA research, oral data is an important window into learners’underlying mental grammars, and may be relatively freer of metalinguistic interference than written data, which is complicated by additional layers of learnt knowledge and monitoring processes. (Myles, 2005, p. 375) Written & spoken corpora
- 16. • Most of the corpus-based SLA studies have used written corpora. • L2 written corpora… are much more readily available than oral ones. (Myles, 2005, p. 375) Written & spoken corpora
- 17. • Most of the studies using corpora… remain rather descriptive, documenting differences between learner and native language rather than attempting to explain them, and the developmental dimension is almost totally lacking. Corpus-based L2 studies are also often not sufficiently informed by SLA theory…. (Myles, 2005, p. 380) Written & spoken corpora

- 19. Learner corpora and SLA research • In SLA research, learner corpora [LC] can be useful in some areas, but not in some other areas. • Questions LC are good at handling • Questions LC cannot really answerQuestions LC cannot really answer Questions LC are good at handling
- 20. Questions LC are good at handling Questions LC cannot really answer • Questions on lexis and collocation • Questions involving morpheme order • Cross-linguistic comparison
- 21. Murakami (2013) Questions LC cannot really answer • Tested the notion of the“natural order”in (e.g., Dulay & Burt, 1973) • Used the Cambridge Learner Corpus (CLC) • Computed the accuracy of six morphemes by learners from six L1 backgrounds • Found a clear L1 influence in some morphemes L1 influence
- 22. Questions LC cannot really answer L1 influence • Findings (relevant to Korean & Japanese) • Articles are ranked low in article-less L1 groups (including Korean & Japanese) • Lower accuracy in plural –s • Higher accuracy in possessive ’s
- 23. Learner corpora and SLA research • In SLA research, learner corpora [LC] can be useful in some areas, but not in some other areas. • Questions LC are good at handling • Questions LC cannot really answer Questions LC are good at handling Questions LC cannot really answer
- 24. Questions LC cannot really answer • Questions as to what is meant by “X has (or has not) been acquired” • Questions derived from more detailed analyses of linguistic phenomena
- 25. Questions LC cannot really answer • Target-like use (TLU) score: number of correct suppliance number of obligatory contexts + number of overgeneralization errors L1 Korean L1 Japanese articles 0.77 0.76 plural –s 0.89 0.88 possessive ’s 0.87 0.80 From Murakami (2013)
- 26. Questions LC cannot really answer • High accuracy (i.e., TLU) even in morphemes ranked“low” • What does the accuracy actually show • Accuracy order vs. acquisition order
- 27. • Target-like use (TLU) score: L1 Korean L1 Japanese articles 0.77 0.76 plural –s 0.89 0.88 possessive ’s 0.87 0.80 third person –s 0.88 0.84 From Murakami (2013) Questions LC cannot really answer
- 28. Third-person singular (3sg) –s Questions LC cannot really answer • In morpheme order studies, accuracy scores are interpreted relative to other morphemes and/or other L1 groups. • What does the 84–88% accuracy actually mean? • Have the Korean & Japanese learners in the CLC acquired 3sg –s?
- 29. Relevant SLA question Questions LC cannot really answer • Representational deficit hypothesis (RDH) vs. Missing surface inflection hypothesis (MSIH) • RDH: Mental representation responsible for inflection is somehow impaired or missing • MSIH: Representation is intact and inflectional errors are caused at a surface level
- 30. Relevant SLA question Questions LC cannot really answer • Representation of subject-verb agreement can be further divided into: • Person (1st, 2nd, & 3rd) • Number (singular & plural)
- 31. Relevant SLA question Questions LC cannot really answer • Studies have employed various methods • Spontaneous production data (e.g., Ionin & Wexler, 2002; Lardiere, 1998) • Oral translation (e.g., Wakabayashi & Yamazaki, 2006) • Self-paced reading (e.g., Jiang, 2004; Shibuya & Wakabayashi, 2008; Wakabayashi, 1997, Jiang, 2004; ) • Event-related potential (ERP; e.g., Wakabayashi et al., 2007)
- 32. What can we do then?
- 33. • More detailed analysis of LC • Discussion on the relation between TLU (accuracy) and knowledge • Use/creation of LC with reduced interference of explicit knowledge (e.g., spoken corpora; severer time pressure in production) What can we do then?
