What is the critical period hypothesis for second language acquisition?
The critical period hypothesis or sensitive period hypothesis claims that there is an ideal time window of brain development to acquire language in a linguistically rich environment, after which further language acquisition becomes much more difficult and effortful.
Why is critical period important in second language learning?
According to the critical period hypothesis, language can be acquired only within a critical period, extending from early infancy until puberty. The hypothesis is untestable for first language acquisition because no child can be intentionally deprived of language for experimental purposes.
Does critical period exist?
Critical period opening Critical periods of plasticity occur in the prenatal brain and continue throughout childhood until adolescence and are very limited during adulthood.

What is the importance of the critical period?
Critical period is an ethological term which refers to a fixed and crucial time during the early development of an organism when it is able to learn things which are essential to survival. These influences impact the development of processes such as hearing and vision, social bonding, and language learning.
How significant is the critical age period in the process of learning a language?
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.
What is critical period in child development?
Children's brains develop in spurts called critical periods. The first occurs around age 2, with a second one occurring during adolescence. At the start of these periods, the number of connections (synapses) between brain cells (neurons) doubles. Two-year-olds have twice as many synapses as adults.
What is meant by the concept of a critical period for language acquisition quizlet?
What is meant by the notion of a critical period for language acquisition? It is the time in one's childhood in which one is particularly sensitive to language cues and most easily acquires language.
