Introduction
Infants are linguistic genius. Kuhl (2004, 2009) discovered that babies are born with the ability to make all the discrimination by languages of the world. Infants use computational strategies and statistically calculate the sound of their caregiver talking to discover all the phonemes and words. But babies lose the ability to hear those differences of other nonnative languages. Kuhl, Conboy, Padden, Nelson and Pruitt (2005) proposed the children early speech perception and implicated the “critical period”. They argued that by the end of the first year, there would be a decline in phonetic discrimination of nonnative phonemes and pointed out that a negative correlation between infants early discrimination phonetic skill of native and nonnative languages. More importantly, at the 7 months of age, the native –and nonnative-phonetic discrimination skills predicts the future language skills.
Kuhl et al. hence hypothesized that the “first critical period” in development happens during 8 to 10 months of age. Which specifies that infants try to maintain the ability to discriminate the phonetic contrast in their native language while lose this ability to nonnative languages. Meanwhile, Friedmann and Rusou (2015) also examined the critical period for first language acquisition while focusing more on syntactic acquisition, the result reclaimed the critical period ends during the first year of life, and children showed syntactic impairments if they lack of proper…
