Age and acquisition

Dispelling Myths

  • Children repeat things over and over again. This is what we must also do.
  • Language learning is imitation. You must be a mimic.
  • First, we practice the separate sounds, then words, then sentences. Natural order = good for language learning.
  • First listening then speaking = right order in language

  • learning.
  • First listening and speaking reading and writing.
  • When small, we do not translate.
  • Children do not use grammar so it is not necessary.

Neurobiological considerations


Lenneberg
(1967)
Lateralization
  • Hemispheric lateralization

  • begins at

around 2 and is completed around puberty
Geschwind
(1970)
Lateralization
Is completed much earlier
Krashen
(1973)
Lateralization
Is completed at 5 years old
Scovel
(1984)
Lateralization
emerges at birth is evident at 5
is completed at around puberty

Neurobiological considerations

  • Biological Timetables

Scovel (1988)
Sociobiological critical period
birds mammals
human beings?
Socially bonding accent
(1) To form an identity with their own community as they anticipate roles of parenting and leadership
(2) To attract mates of “their own kind” in an instinctive drive to maintain their own specie.
Not communicative fluency
Not other “higher-order” processes

Neurobiological considerations

  • Right-Hemispheric Participation

There is a significant right hemispheric participation particularly in early stages of language learning
Obler (1981)
L2 learners, particularly adults, might benefit from more encouragement of right-brain activity in classroom context.

Neurobiological considerations

  • Anthropological evidence

Sorenson (1967)
Tukano culture (South America)
12 languages
1 community => 1 language
1 person
is exposed to 2 or 3 languages
1 person
L1
is exposed to 2 or 3 languages

“The Language acquisition seen in adult
language learners in the largely monolingual American middle class
speech communities may have been inappropiately taken to be universal…” (Hill, 1970)

The significance of accent


“foreign accent”
Speech muscles
gradually develop control complex sounds
are sometimes not
achieved until 5
Complete phonemic control before puberty
“Most of the evidence indicates that persons beyond the age of puberty do not acquire what has come to be called authentic pronunciation”. (Brown, 2007)
Of course… there are exceptions
  • Neuromuscular plasticity
  • Cerebral development
  • Sociobiological programs
  • Environment of sociocultural influences

The significance of accent


We all know people who have less than perfect pronunciation but who also have excellent and fluent control of a second language, control that can even exceed that of many native speakers
