1 CLL Session 8: Age effects in SLA
LAEL, Lancaster University Florencia Franceschina

2 1. Some observable facts Older is better in the short term
Younger is better in the long term Even very extensive exposure does not guarantee native-like attainment

3 Older is better Older learners have been observed to have an advantage in terms of rate of acquisition in the initial stages of SLA, both In naturalistic settings (e.g., Snow and Hoefnagel-Hoehle, 1978) In instructed settings (e.g., six studies in Garcia-Mayo and Garcia-Lecumberri, 2003)

4 Snow and Hoefnagel-Hoehle (1978)
L1 English / L2 Dutch Immersion Tasks: Pronunciation, auditory discrimination, morphology, sentence repetition, sentence translation, sentence judgement, story comprehension, Peabody Picture Vocabulary Test Findings: After 3 months’ residence: adults and adolescents outperformed children on tests After 10 months’ residence: the children caught up

5 Garcia-Lecumberri and Gallardo (2003)
L1 Spanish/Basque / L2 English Instructional setting Start age: 4, 8, 11 Mean time-span of exposure: 6 years for all Tasks: vowel/consonant discrimination, spoken production (measures of intelligibility, degree of foreign accent, overall performance) Most results indicate an advantage for the late starters

6 Younger is better Immigrant studies have shown that there is a negative correlation between age of arrival (AoA) and level of L2 attainment Examples: - Oyama (1976, 1978) - Patkowski (1980) - Johnson and Newport (1989) - Hyltenstam (1992)

7 Long exposure does not guarantee success
Example: Coppieters (1987) 21 L2 French nearnatives LoR in France: years task: intuitions about grammar none of them was within the NS range

8 Other differences between adult and child SLA
Younger and older learners make different types of mistakes in certain areas Example: Lasagaster and Doiz (2003) written production, L2 English 11/15/17 year-olds - younger learners make more spelling mistakes - younger learners resort to codeswitching more often - older learners make more tense mistakes, but they use more complex language than the younger ones

9 2. Accounts of age effects
Critical period vs. General age factors

10 Critical Period Hypothesis (CPH)
Lenneberg’s original formulation (1967) Evidence: Recovery from brain damage (Lenneberg, 1967) Feral children (e.g., Genie - Curtiss, 1977) Late FLA in deaf signers (Mayberry, 1993)

11 Exercise: Who are these people? Which one is the odd one out? Why? Victor of Aveyron Kaspar Hauser Kamala and Amala Ivan Mishukov

12 General age factors Example: Bialystok (1997), Bialystok and Hakuta (1994) argue against a cut-off point, and for a continuous decline of language learning abilities
