ABSTRACT
Recent years have witnessed major changes in the conception of human ability. Ability is not a fixed attribute in a behavioral repertoire. Rather, it is a generative capability in which cognitive, social, motivational, emotional, and behavioral skills must be organized and effectively orchestrated to serve innumerable purposes. There is a marked difference between possessing knowledge and skills and being able to use them proficiently under diverse circumstances, many of which contain ambiguous, unpredictable, and stressful elements.
