Lenneberg formed the critical period hypothesis theory which contends that language is innate but has to be attained before the age of puberty or else the ability to learn language ebbs (as a result of the lateralization of the brain) 1 at present, the critical period hypothesis theory is widely accepted by numerous linguists.
The critical period hypothesis says that there is a period of growth in which full native competence is possible when acquiring a language this period is from early childhood to adolescence the critical period hypothesis has implications for teachers and learning programmes, but it is not universally accepted acquisition theories say that. The critical period hypothesis, or its idea, was first introduced by penfield and roberts, who argued that language acquisition is most efficient before “the human brain becomes stiff and rigid” (1959:236. In psychology the term is most often associated with language acquisition as the critical period hypothesis popularised by lenneberg (1967) hypothesised that language learned outside the critical period for language learning would develop abnormally, never reaching a native level of fluency. The critical period hypothesis (cph) is the essence of this considerations lenneberg tries to find evidence for his theory in the study of retarded, aphasic or deaf children and in neurological studies but at this time the most striking proof for the cph, genie, was still imprisoned in a small room in her parents home three years after.

Critical period for language acquisition, then l2a during the critical period should resemble first language acquisition (lia) because both processes are governed by the learner's access to those p rinciples.
The ‘critical period hypothesis’ (cph) is a particularly relevant case in point this is the claim that there is, indeed, an optimal period for language acquisition, ending at puberty however, in its original formulation lenneberg 1967), evidence for its existence was based on the relearning of impaired l1 skills, rather than the learning of a second.
