It has been hypothesized that there is a critical period for first-language acquisition that extends into late childhood and possibly until puberty. The hypothesis is difficult to test directly because cases of linguistic deprivation during childhood are fortunately rare. We present here the case of E.M., a young man who has been profoundly deaf since birth and grew up in a rural area where he received no formal education and had no contact with the deaf community. At the age of 15, E.M. was… Expand
Language Acquisition in Late Critical Period: A Case Report
Abstract Studies carried out to support the existence of a critical period for language acquisition have concentrated mainly on the case of being in total deprivation from language contact, and inExpand
Grammatical development in adolescent first-language learners
Studies of first-language acquisition in adolescence are very rare and depend primarily on comprehension measures to evaluate grammatical knowledge. These studies have led to the general conclusionExpand
Language acquisition for deaf children: Reducing the harms of zero tolerance to the use of alternative approaches
TLDR
An alternative to speech-exclusive approaches to language acquisition exists in the use of sign languages such as ASL, where acquiring a sign language is subject to the same time constraints of spoken language development. Expand
Imagination exercises improve language in younger but not in older children with autism suggesting a strong critical period
TLDR
Findings support Lenneberg's critical period hypothesis and indicate that acquisition of voluntary imagination is essential for the full language acquisition and imply that the underlying plasticity dramatically diminishes after the age of five and therefore even greater therapeutic intervention should be targeting the very first years of a child's life.

What Sign Language Reveals about the Critical Period for Language
This chapter examines the critical period for language through the prism of deafness.The first topic is the concept of critical periods, followed by a summary of research investigating age ofExpand
Ensuring language acquisition for deaf children: What linguists can do
Parents of small deaf children need guidance on constructing home and school environments that affect normal language acquisition. They often turn to physicians and spiritual leaders and,Expand
Acquiring a first language in adolescence: the case of basic word order in American Sign Language
TLDR
The early syntactic development of adolescent first language learners is studied by examining word order patterns in ASL, suggesting that adolescent L1 learners go through stages similar to child native learners, although this process also appears to be prolonged. Expand
The initial stages of first-language acquisition begun in adolescence: when late looks early.
TLDR
The current study investigates three cases of young teens who are in the early stages of acquiring American Sign Language (ASL) as a first language, to determine what first-language acquisition in adolescence looks like. Expand
Effects of Early Language Deprivation : Mapping between Brain and Behavioral Outcomes
One core issue regarding language development is the role of early language experience. The literature on child language development has found that the quality and quantity of early language input isExpand
Linguistically deprived children: meta-analysis of published research underlines the importance of early syntactic language use for normal brain development
TLDR
All tests performed on linguistic isolates are ranked by their reliance on the LPFC control of the posterior cortex, showing that purposeful construction of novel mental images is the function of the lateral prefrontal cortex (LPFC) ability to dynamically control posterior cortex neurons. Expand

New evidence is presented that modifies Lenneberg's (1967) proposed critical period of language acquisition. The development of lateralization is complete much earlier than puberty and is thus not aExpand

The results support the conclusion that a critical period for language acquisition extends its effects to second language acquisition. Expand

TLDR
The authors' analysis appears to indicate a relative hemispheric equipotentiality which permits the transfer of language representation to the opposite hemisphere in the case of a unilateral lesions in childhood. Expand

TLDR
This paper suggests that there are constraints on learning required to explain the acquisition of language, in particular, mului ultonol constraints, and suggests that language learning abilities decline because of the expansion of nonlinguisftc cognitive abilities. Expand
