Aptitude is inborn potential to perform certain kinds of activities, whether physical or mental, and whether developed or undeveloped.
[1] The mass term ability refers to components of competence acquired through a combination of both aptitude and skills.
[4] Talented individuals generally show high levels of competence immediately in only a narrow range of activities,[5] often comprising only a single direction or genre.
For example, the U.S. Department of Labor's General Learning Ability is determined by combining Verbal, Numerical and Spatial aptitude scores.
Aptitude tests can typically be grouped according to the type of cognitive ability they measure, whether that be fluid or crystallized intelligence.
