Toward a more comprehensive theory of exceptional abilities

In our response to Professor Francoys Gagne, we suggest a more comprehensiv e theory of elite performance. This theory is composed of three components: general intelligence, domain-specific skills, and practice. Evidence is pr esented in support of this position. In addition, we take a harder line on a number of issues: (a) There is no doubt that 50% or more of cognitive abi lity is genetically determined; (b) domain specific skills must be included to account for phenomena like savants; and (c) practice alone cannot accou nt for expertise. Finally, we discuss the need for explicit definitions of gifted and talented. We conclude that if education were properly individual ized, such definitions would not be necessary.
