Treffert: "At the 1964 annual meeting of the American Psychiatric Association, a discussant concluded, 'The importance, then, of the Idiot-Savant lies in our inability to explain him; he stands as a landmark of our own ignorance and the phenomenon of the Idiot-Savant exists as a challenge to our capabilities.' In the years that have followed, the inability to explain the idiot savant has not lessened, and the challenge to our capabilities ... undiminished. However, no model of brain function, particularly memory, will be complete until it can account for this rare but spectacular condition, with its islands of mental ability in a sea of mental handicap and disability. "Through the past century, since Down's description of this disorder, the several hundred idiot savants reported in the world literature have shown remarkable similarities within an exceedingly narrow range of abilities, given the many possible skills in the human repertoire. Why do so many idiot savants have the obscure skill of calendar calculating? Why does the triad of retardation, blindness, and musical genius appear with such regularity among them? Why is there a 6:1 male-to-female ratio in this disorder? What accounts for the more common occurrence of the idiot savant ...

Science Frontiers ONLINE No. 65: Sep-Oct 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Calendar calculating by "idiot savants"M.J .A . Howe and J. Smith have reported on an extensive study of calendar-calculating by individuals with otherwise subnormal intelligence. It is very clear that these so-called "idiot savants" use a variety of mental techniques, all rather different from rote memory, such as employed by memorizers of pi. First, we present Howe-and-Smith's abstract; then, a particularly interesting specific case. "A number of mentally handicapped individuals are able to solve difficult calendar date problems such as specifying the day of the week for a particular date, sometimes over ... of more than 100 years. These individuals are self-taught and do not follow procedures at all similar to the usual, published, algorithms. An investigation of one individual revealed that he retained considerable information about the structure of days in particular months, probably as visual images. His skill closely depended on the extent and form of his knowledge of calendars, and his errors were often a consequence of lack of knowledge about a particular time period. Mentally retarded individuals who perform calendar date feats are often socially withdrawn and devote considerable periods of time to calendar dates. The most capable calendar-date calculators are usually individuals who have a strong interest in calendars as such." Although some calendar calculators may use visual imagery - perhaps something like eidetic imagery - at least one calendar calculator was blind ...

... that perfect pitch, though common in musicians, occurs only in about 1 of every 10,000 people. Among the autistic, however, the incidence rises to perhaps 1 in 20. He next moves on to "savants;" that is, individuals with exceptional mathematic, mechanical, musical, and artistic talents, but with serious deficiencies in other human attributes. Calculating prodigies and other "idiot savants" immediately come to mind here. Sachs claims that perfect pitch is is even more common among the savants. In fact, all muscial savants seem to have it. Perfect pitch is also common among those with Williams syndrome, which he defines as: "a -- syndrome which predisposes to hyperacusis and exceptional development of auditory, musical, and verbal skills, combined with striking visual ... asymmetry observed in musicians with perfect or absolute pitch* (SF#99), O. Sacks expands the domain of the phenomenon to include other human talents. Sacks says that perfect pitch, though common in musicians, occurs only in about 1 of every 10,000 people.

... 7; the remainder gives the day of the week. For example, 27 October 1964 gives 27+ 1 (the code for October)+ 3 (the code for 1964) = 31. Dividing by 7 gives a remainder of 3 which is the third day of the week, Tuesday." (Ref. 2) Note the connection between TM's feats and those of those idiot savants adept at calendar-calculating. Demonstration 3. TM quickly gives the telephone number of any of the 15,000 hotels listed in a large directory. "The telephone have been learned through a mnemonic system for encoding numbers as a series of two-digit pairs. Each pair has a learned associate (e .g . 00 is a bicycle, 57 is tomato sauce, 39 ... Hitler, 41 is mum, his mother's age when he started this system). For larger numbers these associates are combined into wholes which are usually highly imageable (a bottle of tomato sauce riding a bicycle) and attached to some other associate to the hotel name." (Ref. 2) TM's mnemonics seem weird, but they work; and they probably could work for anyone -- for we barely tax our mental powers in modern life. But would our latent mental capabilities been of use to ancient man, or is this still another case of "evolutionary overshoot", as we harped on so heavily under BIOLOGY in this issue? References 1.

... of a Pendulum," New Scientist, p. 37, July 24, 1986.) Comment. Some of the anomalies we record may be the consequence of simple systems gone wild. Chaotic motions of some asteroids and at least one solar system moon are already suspected. Imagine what might happen in much more complex systems, such as biological evolution (hopeful monsters?), brain development (idiot savants?), etc. From Science Frontiers #47, SEP-OCT 1986 . 1986-2000 William R.
