Giftedness generally refers to talents, abilities, or intellect that is beyond what is considered "normal." These well above-average abilities are normally noted in childhood and continue into adulthood. The term giftedness (at least in academic subjects) is frequently used interchangeably with "genius" which psychologists quantify as scoring in the top 2% of IQ's. However, a person can also display giftedness in non-academic subjects such as art or music. Extreme examples of this throughout history include Da Vinci, Einstein, and Mozart.
