There is evidence supporting the idea that it is easier to learn a new language between the ages of 2 and 10. This period is often referred to as the "critical period" for language acquisition[1][4]. A study published in the journal Cognition found that it is nearly impossible for language learners to reach native-level fluency if they start learning a second language after age 10[4]. However, this does not mean that language skills decline at this age; in fact, people still learn quickly between the ages of 10 and 18, but they have a shorter window before their learning ability declines, making it harder for them to achieve the proficiency of native speakers[1].
Some key findings from the research include:
- The critical period for language acquisition might be longer than previously thought, with some scientists believing it closes shortly after birth, while others stretching it only to early adolescence[4].
- The largest dataset ever assembled for a study of language-learning ability, consisting of a grammar quiz taken by nearly 670,000 people, was used to analyze the critical period for language learning[1].
- While it is typical for children to pick up languages more easily than adults, this trend has been difficult to study in a laboratory setting[1].
In conclusion, there is evidence to support the idea that it is easier to learn a new language between the ages of 2 and 10, as this period is considered the critical period for language acquisition. However, it is still possible to learn a language after this age, but achieving native-like proficiency becomes more challenging[1][4].
