Methodology in Language Learning: Language Aptitude and Age

Does language aptitude change with age either in a positive or in a negative way? On the one hand, if language aptitude is indeed a trait, it should be relatively stable. Intelligence, for example, has been found to be remarkably stable. The other side of the coin, however, is that age is a central factor in an individual’s language learning capacity—as evidenced by the vast amount of literature on the ‘critical period hypothesis’ addressing age-related changes in SLA—and therefore it is not unreasonable to assume that some of the age-related variation is mediated through aptitude changes that occur over time. In sum, there are several findings in this study that provide some support nor the argument that analytical language ability is more closely associated with second language outcomes when intensive exposure to the language is first experienced in adolescence. This relationship appears to hold, though not as strongly, even when exposure takes place in an environm...
