Language Acquisition After Puberty (Strozer)
Chapter 1
Claim # 1: No nonhuman animal is capable of mastering a human lg. Claim # 2: Any normal child can become a native sp. Of a lg.
Human vocal track develops in a very specific way. The attempt to teach a chimp, Vickie, to talk failed. The vocal track of chimps are not suitable for a human lg. Other experiments with chimps can be analyzed as stimulus-response
cases. Human languages are not limited to the spoken modality. Chimps lack the mental makeup required by human lg. What chimps posses is their own semiotic system of communication,
which has nothing in common with human lg. A human lg. is more than vocabulary. It is a highly intricate system, a
generative procedure. The same string of words may mean different things for humans (Mary
taught John Spanish vs. John taught Mary Spanish). Attaining a lg. is not something that the child does, but rather something
that happens to the child who is in the right place at the right time.
Claim # 3: All and only (normal) can attain language natively. (the “never after puberty thesis)
Only before puberty (give or take a few years) is it possible for a human to attain language natively, become bona fide native speakers.
Minimal definition of human lg: a system that relates a meaning to a signal over and unbounded range of meanings and signals.
The lg experience is very different when the would-be speakers have not reached puberty and when they are past puberty.
Any child who is part of a linguistic community comes to be in possession of at least one language at a tender age, by the time the child reaches puberty his or her linguistic maturation has reached a steady state.
The adolescents or adults striving to develop competence in a language usually avail themselves of instruction.
A foreign lg program needs to be carefully designed. The randomness of first language acquisition is not a good model for language teaching.
Chapter 2
Our knowledge cannot all be due to nature. Phenotype: The appearance of an organism resulting from the interaction
of the genotype and the environment. Genotype: the genetic makeup of an organism or group of organisms
with reference to a single trait, set of traits or and entire complex of traits. Familiarity tends to breed the sort of attitude that makes it difficult for us
to perceive the obvious. Little exposure to language had only a minor effect on their eventual
language achievement (deaf-blind adults). Deaf children with zero linguistic input have been able to spontaneously
develop a sign system remarkably like human language. There is evidently an innate capacity for language. The environment provides sounds or signals. The lg faculty is part of an individual’s genetic construction, that is, of his
or her genotype and that the phenotype of the mature individual is the outcome of the interaction the genotype with experience.
The environment is too poor and too unorganized to provide what is needed.
There are lg principles of human nature that are part of the human brain. Language faculty (traditional term) or cognitive structure for language. Lg. appears to be a by-product of the relative increase in the size and
complexity of the brain. If lg is genetically programmed at birth why do we all not speak the same
language? The language faculty is a sort of mental organ Broca’s area: the area of the frontal lobe associated with lg. Wernicke’s area is somewhat larger than Broca’s. It was then discovered that Wernicke’s area is larger than thought,
extending to parts of the left parietal lobe. The two major areas are part of the left hemisphere.
