Characteristics
According to psychiatrist Darold Treffert, almost all savants have special, prodigious memory, which he describes as "very deep, but exceedingly narrow". It is narrow in the sense that they can have exceptional memory but some of them have difficulty putting it to use. Savant skills are usually found in one or more of five major areas: art, musical abilities, calendar calculation, mathematics and spatial skills.
