ASSOCIATION BETWEEN PERFORMANCE SCORE ON APTITUDE-TESTS AND SPEED OF EXECUTION

The relationship between the speed of execution and the ability of a s ubject when performing mental tasks is a longtime concern of psychomet ric researchers. However, this relationship is not well documented bec ause execution speed has been measured inaccurately in the past. The r elationship between speed of execution and intellectual ability is eva luated here while using subtests from a French Canadian computerized b attery of aptitude tests, the Tests d'aptitudes informatises pour enfa nts, which adequately provide control of the response time for each pr esented item. The speed of execution indices we examined here are calc ulated from the easiest items of six subtests. Those indices are compa red with the scores on these subtests as well as with other indices of intellectual ability. The sample comprises 148 children whose average age was 10 years. Analysis suggests that high speed and high scores a re related for some types of mental work.
