[sci.lang] accents in adult language learners

rolandi@gollum.UUCP (12/05/87)

Among linguists it is accepted as a truism that infants the world over
emit the same set of basic phonemic babblings.  If all infants start out 
with the same set of babblings, presumably a superset of the IPA, what 
happens to them as their users get older?   Why can't adults call up the
constituents of these elemental babblings when acquiring a foreign 
language and thereby do so without retaining an accent?

Because these "constituents" have become the victims of disuse.

When a child learns only one language, the child's culture essentially
ignores all phonemic utterances that are not included in its language.
Although initially included in the infant's behavioral repertoire, phonemes
unused by the verbal community do not mediate reinforcement.  They thereby
become less probable, ultimately falling entirely from the repertoire.
Whether or not this motor loss is accompanied by changes in neurology is
an experimental question, but the CAUSE of the behavioral loss is the fact
that they are unreinforced by the child's verbal community. (see Skinner, 1957)

There may well be some neurological correlate to this change in linguistic
ability.  But before one is to assume that some neural process is the CAUSE, 
(like our handy and unexplained explanation, the "crystallization process")
I think one should first consider the possibility that the neural process 
is instead the EFFECT.  Would anyone seriously maintain that unused muscles
do not fall to atrophy?

it's refreshing to see someone scrutinize the acquisition method before
jumping to the conclusion that there is some internal mechanism involved.
Unlike the hypothesized internal mechanism, methods of acquisition are
much more available to experimentation.  To say that adults do not
learn languages without accents does not mean that they CANNOT do so.  The
question at this point becomes, "How does one TEACH an adult a second
language without retaining an accent?"  I'd like to pose that question
to any speech pathologists out there.....
