Natural selection of the critical period for language acquisition.
The language acquisition period in humans lasts about 13 years. After puberty it becomes increasingly difficult to learn a language. We explain this phenomenon by using an evolutionary framework. We present a dynamical system describing competition between language acquisition devices, which differ in the length of the learning period. There are two selective forces that play a role in determin...

since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
15 صفحه اولThe evolution of the critical period for language acquisition.
Evidence suggests that there is a critical, or at least a sensitive, period for language acquisition, which ends around puberty. The existence of this period is explained by an evolutionary model which assumes that (a) linguistic ability is in principle (if not in practice) measurable, and (b) the amount of language controlled by an individual conferred selective advantage on it. In this model,...

15 صفحه اولAssess the Critical Period Hypothesis in Second Language Acquisition
The ultimate attainment level of Second Language Acquisition (L2A) contrasts sharply with that of First Language Acquisition (L1A) (Birdsong, 1999, p.1). That is: various success versus universal success (Gleitman & Newport, 1995, p.1). This significant difference between L1A and L2A is explained by the Critical Period Hypothesis (CPH). The CPH states that for language acquisition, either first...
