  • Studies in Second Language Acquisition
This article reviews the second language research on age-related differences, as well as first language work needed to disambiguate some of the findings. Five conclusions are drawn, (a) Both the initial rate of acquisition and the ultimate level of attainment depend in part on the age at which learning begins. (b) There are sensitive periods governing language development, first or second, during which the acquisition of different linguistic abilities is successful and after which it is…

Maturational Constraint : The Effect of Age of Acquisition on Second Language Comprehension and Pronunciation in Second Language Acquisition
It is a common belief that children, when compared to adult, acquaint themselves easier with a foreign language. This phenomenon has been described as the “critical period hypothesis” by Long and
Maturational constraints in language one and language two: A second look at the research on critical periods
Abstract Research on first language acquisition in young children and second language learning in older children and adults has examined the possible role played by maturational constraints (related
Nonconvergence on the native speaker grammar: Defining L2 success
The issue of critical or sensitive periods affecting the outcome of second language (L2) acquisition has been the subject of intense investigation and debate for many years, with people arguing for

TLDR
This article concludes with a short discussion — in the light of the foregoing — of the degree of absoluteness of the age factor in L2 acquisition; and the notion that there may be not one, but a number, of age-related factors at work.
Second Language Acquisition in Early Childhood
There is a broad consensus in the research literature on the acquisition of bilingualism that the simultaneous acquisition of two (or more) languages can be qualified as an instance of bilingual
Changing perspectives on universal grammar and the critical period hypothesis
It has long been claimed that there is a critical or sensitive period (or periods) for language acquisition, a period with lower and upper bounds during which language acquisition is best achieved
Temporal dynamics of late second language acquisition: evidence from event-related brain potentials
The ways in which age of acquisition (AoA) may affect (morpho)syntax in second language acquisition (SLA) are discussed. We suggest that event-related brain potentials (ERPs) provide an appropriate
Problems with supposed counter-evidence to the Critical Period Hypothesis
Abstract While almost all observers agree that young children, older children, and adults differ both in initial rate of acquisition and in the levels of ultimate attainment typically achieved, they
Individual Differences in Sequence Learning Ability and Second Language Acquisition in Early Childhood and Adulthood
Language aptitude has been hypothesized as a factor that can compensate for postcritical period effects in language learning capacity. However, previous research has primarily focused on instructed
LANGUAGE ACQUISITION AFTER THE CRITICAL PERIOD : DO ADULT LEARNERS FOLLOW A DIFFERENT ROUTE IN SECOND LANGUAGE ACQUISITION ?
The effect of age on second language acquisition represents one of the most recurrently investigated and debated issues in the scope of Second Language Acquisition. There is a broad agreement among

Age Differences in the Pronunciation of Foreign Sounds
TLDR
Two kinds of data are presented which suggest that younger children are not better than older children and adults in learning a foreign language, and the ability to imitate foreign words under controlled input conditions increased linearly with age.
