Second Language Acquisition and the Critical Period Hypothesis
Critical Period For Language Acquisition - Business Insider
Early Foreign Language Instruction is “Not a Magical Tool”
In The Age Factor in Second Language Acquisition, David Singleton concedes that in second-language instruction, “younger = better in the long run.” But this is a general rule with plenty of exceptions. The exceptions include the 5 percent of adult bilinguals who master a second language even though they begin learning it when they are well into adulthood, long after any critical period has presumably come to a close.

As John T. Bruer, author of The Myth of the First Three Years, states: “One of the dangers of the…emphasis on critical periods, is that it prompts us to pay too much attention to when learning occurs and too little attention to how learning might best occur.” Marshall agrees, pointing out that learning a foreign language in elementary school—what most researchers generally agree is the ideal time—is not a “magical tool for creating perfect second-language speakers.” Timing, in other words, is not everything.
Case Study of Genie - Critical Period Hypothesis
The critical-period hypothesis for second-language acquisition was tested on data from the 1990 U.S. Census using responses from 2.3 million immigrants with Spanish or Chinese language backgrounds. The analyses tested a key prediction of the hypothesis, namely, that the line regressing second-language attainment on age of immigration would be markedly different on either side of the criticalage point. Predictions tested were that there would be a difference in slope, a difference in the mean while controlling for slope, or both. The results showed large linear effects for level of education and for age of immigration, but a negligible amount of additional variance was accounted for when the parameters for difference in slope and difference in means were estimated. Thus, the pattern of decline in second-language acquisition failed to produce the necessary discontinuity that is an essential hallmark of a critical period.
