Metalinguistic knowledge (whether learned
explicitly or implicitly) is typically greater with
adolescents than with very young children.
A, L and S's article studied 5th
and 6th graders
Those who showed some signs of metalinguistic
knowledge were more successful (and faster) at
acquiring L2.
Singleton also acknowledged that
knowledge of "a" language helps in
acquisition
Center for Applied Linguistics (CAL) Digest
Younger learners are more successful in pronunciation
than older students; but other aspects of success are not
guaranteed
Ortega
Age may play a role, but it's much more
complex than a biological issue; many
contextual factors must be accounted for.
Singleton would agree.
Marinova-Todd would also agree.
Studies by Long suggest that adult learners have an
advantage for maybe 1-3 years, but young learners will have
a greater long term advantage.
A study by Muñoz, however, suggests
that younger learner never catch up
to the advantage of the older starting
learners.
Conclusion: there is no consensus among researchers.
Many, many factors of the learner's context affect the
outcome of the success of the acquisition.
Primary Issues in age and SLA:
Information supporting the claim that younger
learners are more successful is anecdotal.
Address by a CAL Digest (By Don Snow) paper
that gives the 5 myths
Marinova-Todd
Argues that studies do not support the claims that adults are unsuccessful at SLA
Researchers have made 3 mistakes
1. Misinterpretation
Speed of young children acquiring L2
quickly is simply anecdotal
information
2. Misattribution
Neurobiological studies have faulty conclusions because of
misattributing (incorrectly connecting) the changes that
happen in the brain to language learning.
3. Misemphasis
Research has ignored those adult learners who have
sucessfully acquired an L2 and focused primarily on the
unsuccessful learners
Age may very well be related to sucess/rate of SLA; but this CANNOT be confused with biology alone.
Marinova-Todd suggests that age related differences are connected to the
"situation of learning" (environmental factors) rather than the "capacity"
(biological) of learning
Singleton also affects are more than age related. A
"desire" to learn is another factor.
Motivation may help or hinder
Motivation may be different at different ages.
CAL article suggests more than biological issues: also
psychological and social--yes, these might be different
at different ages
