| Abstract: | A group of bright-average 7th grade junior-high-school students was contrasted with a group of manifestly academically gifted students of comparable age who were taking college-level courses in mathematics and science. The groups differed significantly and markedly (showing an overall mean difference of 1.34 SD) on every one of the nine different reaction-time (RT) tasks measuring the speed with which persons perform various elementary cognitive processes. The results indicate that: (1) various RT measurements discriminate about as much between intellectually average and superior groups as past studies have found RT measurements to discriminate between average and subnormal groups: and (2) the academically gifted differ from their nongifted age-peers in more than just scholastic knowledge and advanced problem-solving skills—they differ fundamentally in speed of information processing on extremely simple cognitive tasks with average response latencies of between 0.3 and 1.5 sec. |
