Intellectual Giftedness: Signs and Symptoms

"Generally, gifted individuals learn more quickly, deeply, and broadly than their peers. Gifted children may learn to read early and operate at the same level as normal children who are significantly older. The gifted tend to demonstrate high reasoning ability, creativity, curiosity, a large vocabulary, and an excellent memory. They often can master concepts with few repetitions. They may also be physically and emotionally sensitive, perfectionistic, and may frequently question authority."

I especially appreciate that list bit pertaining to authority. Pretty accurate, eh?
