May also include vivid dreams, fear of the unknown, poetic creativity, or love of fantasy. Persistence in asking probing questions, love of knowledge, discovery, theoretical analysis and synthesis, independence of thought. This is not the same as IQ, which is the ability to solve a problem. Intellectual overexcitability is the love of solving the problem.

It's easy to see that someone with psychomotor overexcitability has a high likelihood of meeting the DSM IV criteria for ADD with hyperactivity. In the real world, it seems that a bright child with overexcitabilities who is doing well in school will be labeled gifted. But if the same child underachieves in school, the ADD label might be used instead. And many gifted students may be underachievers. Or even more.
