What does the term "language aptitude" refer to in the context of the DLAB?

The term "language aptitude" refers specifically to a person's potential to learn new languages, which is fundamental to the DLAB's purpose. The DLAB assesses various cognitive abilities that correlate with how well an individual can acquire and process new languages. This potential encompasses a range of skills, such as phonetic coding ability, grammatical sensitivity, and memorization, which are indicative of someone’s capacity to grasp and utilize linguistic principles in a new language.

Knowledge of multiple languages, the ability to teach languages to others, and fluency in one's native language are all related to language skills but do not directly encapsulate the concept of "aptitude." Knowledge of multiple languages implies an experience level rather than potential, teaching ability emphasizes knowledge transfer rather than personal acquisition, and fluency in one’s native language, while beneficial, does not necessarily predict aptitude for learning additional languages.
