Download - Critical period hypothesis
The crticial period hypothesis in essence contends that the ability to learn a language is limited to the years before puberty after which, as a result of neurological changes in the brain the ability is lost.
Feral Children
unless exposed to lg in the early years of life, humans lose much of their innate ability to learn a language
Compelling evidence of feral, confine and isolated children
FC don't provide the best evidence partly because of sub normality

In the classroomA problem arising from the differences between
younger learners and adults is that adults believe that they cannot learn languages well.
Teachers can help learners With this belief, for ex, by talking about the learning process and styles, helping set realistic goals, choosing suitable methodologies, and addressing the emotional needs of the adult
learner.
co-ordinated bilingualismChildren develop two parallel linguistic systems, so
that for any one word. when the two parents have different mother
tongues and each parent speaks only his or her own mother tongue to the child.
the child constructs two separate linguistic systems and can handle each of them easily.
Another situation is when relatively young children who have already mastered their mother tongue are adopted by parents who speak a different language.
Once again, the distinction between the two languages is crystal-clear for the child.
compound bilingualismChildren have only one signified for two signifiers
and so cannot detect the conceptual differences between the two languages.
Compound bilingualism is what occurs when both parents are bilingual and both parents speak to the child in both languages indiscriminately.
The child will grow up to speak both languages effortlessly and without an accent, but will never master all the subtleties of either of them. In other words, the child will not really have a mother tongue.
Late bilingualism Late bilingualism is developed after the
critical period for language learning. In such cases, it is thought that when people
acquire their second language through immersion in a community that speaks it
Implicit memory plays more of a role, whereas when they do so solely through formal classroom studies, explicit memory is more involved.
