It is important to keep in mind that, given enough time and reasonably good instruction, virtually anyone can learn a second language, but people differ in terms of the rate and ease with which they can learn. Scores from a language aptitude test can therefore be used to help to determine how much time will be sufficient for an individual language learner to accomplish a given goal, assuming that the individual has at least some motivation to learn. Carroll, an internationally acclaimed psychometrician and educational psychologist, conducted a five-year research project in the s to investigate the concept of language aptitude and how it could be measured. During this time, Carroll identified four distinct abilities that factored into language aptitude, separate from motivation and verbal intelligence. Carroll designed the Modern Language Aptitude Test based on this four-part model of language aptitude.
