AP PSYCHOLOGY

Detailed explanation-1: -The critical period hypothesis states that the first few years of life is the crucial time in which an individual can acquire a first language if presented with adequate stimuli, and that first-language acquisition relies on neuroplasticity.

Detailed explanation-2: -The critical period hypothesis (CPH) states that the first few years of life constitute the time during which language develops readily and after which (sometime between age 5 and puberty) language acquisition is much more difficult and ultimately less successful.

Detailed explanation-3: -The learning theory of language acquisition suggests that children learn a language much like they learn to tie their shoes or how to count; through repetition and reinforcement. When babies first learn to babble, parents and guardians smile, coo, and hug them for this behavior.

Detailed explanation-4: -(Owens, 2012) There are four theories that explain most of speech and language development: behavioral, nativistic, semantic-cognitive, and social-pragmatic.

Detailed explanation-5: -There are three theories of language acquisition: cognitive, inherent, and sociocultural. Each theory has specific aspects that make each of them unique in its development of language.
