Lenneberg (1967) hypothesized that language could be acquired only within a critical period, extending from early infancy until puberty. In its basic form, the critical period hypothesis need only have consequences for first language acquisition. Nevertheless, it is essential to our understanding of the nature of the hypothesized critical period to determine whether or not it extends as well to second language acquisition. If so, it should be the case that young children are better second… Expand
Critical period effects on universal properties of language: The status of subjacency in the acquisition of a second language
The results suggest that whatever the nature of the endowment that allows humans to learn language, it undergoes a very broad deterioration as learners become increasingly mature. Expand
Language Acquisition During and After Critical Period (A Comparative Review Between Children and Adults)
This research paper is a review of the previous literature that focuses on whether or not there is an influence of second language acquisition during 'critical period'. Critical period refers toExpand

On the evidence for maturational constraints in second-language acquisition
Second-language (L2) acquisition is generally thought to be constrained by maturational factors that circumscribe a critical period for nativelike attainment. Consistent with the maturational viewExpand
Critical Period Constraints In The Second Language Acquisition Of Syntax: The Case Of EFL Arabic Learners Of English
Age is believed to be a determining factor in achieving native-like competence in second language (L2) acquisition. The Critical Period Hypothesis (Lenneberg, 1967) states that native competenceExpand
Critical Period Effects in Second Language Acquisition: The Effect of Written versus Auditory Materials on the Assessment of Grammatical Competence†
Current research has supported the existence of a critical period for the acquisition of the grammar of a second language. In one study, native speakers of Chinese and Korean, who had arrived in theExpand
Age Constraints on Second-Language Acquisition
This study evaluated the critical period hypothesis for second language (L2) acquisition. The participants were 240 native speakers of Korean who differed according to age of arrival (AOA) in theExpand
The Effects of Age on the Rate of Learning a Second Language
The present study evaluates the role of age on the rate of acquiring English as a second language in an immersion setting. Subjects were children with native languages typologically very differentExpand
Maturational Constrains and Second Language Acquisition by Iranian Second Language Learners
Second-language (L2) acquisition is generally thought to be constrained by maturational factors that circumscribe a critical period for native-like attainment. Consistent with the maturational viewExpand
Cross-linguistic evidence for the nature of age effects in second language acquisition
ABSTRACT Few researchers would doubt that ultimate attainment in second language grammar is negatively correlated with age of acquisition, but considerable controversy remains about the nature ofExpand


Age Differences in the Pronunciation of Foreign Sounds
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. Expand
The sensitive period for the acquisition of syntax in a second language.
This research tested the hypothesis that learners whose exposure to a second language begins before the age of 15 years achieve higher syntactic proficiency in the target language than adultExpand
The Relationship Between Age and Accuracy of Foreign Language Pronunciation.
AbstractThe assumption that younger children can master the phonological system of a second language more easily than those who are older was tested under laboratory conditions. This assumption isExpand
The Sensitive Period and Comprehension of Speech
The sensitive period as a developmental concept is discussed. Observations are made on various problems involved in attempting to explain adult difficulties with second language acquisition byExpand
A sensitive period for the acquisition of a nonnative phonological system
Immigrants who had learned English at various ages and who had been in the United States for various amounts of time were judged for degree of accent in English. It was found that age at arrival wasExpand
Trends in Second-Language- Acquisition Research
Recent concern with bilingual education has led to an increased interest in understanding the process of second-language acquisition. In this article Kenji Hakuta and Herlinda Cancino present aExpand
Age, Rate and Eventual Attainment in Second Language Acquisition.
(1) Adults proceed through early stages of syntactic and morphological development faster than children (where time and exposure are held constant). (2) Older children acquire faster than youngerExpand
The current status of the motherese hypothesis.
The new analysis suggests that increased complexity of maternal speech is positively correlated with child language growth in this age range, and most effects of the mother on the child's language growth are found to be restricted to a very young age group. Expand
Formal Principles of Language Acquisition
The authors of this book have developed a rigorous and unified theory that opens the study of language learnability to discoveries about the mechanisms of language acquisition in human beings and has important implications for linguistic theory, child language research, and the philosophy of language.

The learning strategy of the total physical response: some age differences.
This study compared the listening comprehension of 8-, 10and 14-year-old children, and college adults when each S was in physical action during retention tests to show that the adults were superior to the children of any age group at p < .0005. Expand
