She Has a Perfect Memory

I found this story to be very interesting, but I can’t remember why.

“McGaugh’s journey through an intellectual purgatory began six years ago when a woman now known only as AJ wrote him a letter detailing her astonishing ability to remember with remarkable clarity even trivial events that happened decades ago.

Give her any date, she said, and she could recall the day of the week, usually what the weather was like on that day, personal details of her life at that time, and major news events that occurred on that date.

Like any good scientist, McGaugh was initially skeptical. But not anymore.

“This is real,” he says.

Soon after AJ took over his life, McGaugh teamed with two fellow researchers at the University of California at Irvine. Elizabeth Parker, a clinical professor of psychiatry and neurology (and lead author of a report on the research in the current issue of the journal Neurocase), and Larry Cahill, an associate professor of neurobiology and behavior, have joined McGaugh in putting AJ through an exhaustive series of interviews and psychological tests. But they aren’t a lot closer today to understanding her amazing ability than they were when they started.

“We are trying to find out, but we haven’t hit ‘bingo’ yet,” says McGaugh.

His initial hypothesis, like several others, has turned out to be wrong — or at least incomplete.

McGaugh has spent decades studying how such things as stress hormones and emotions affect memory, and at first he thought AJ’s memories were of such emotional power that she couldn’t forget them.

But that hypothesis fell short of the mark when it became obvious that “the woman who can’t forget” remembers trivial details as clearly as major events. Asked what happened on Aug 16, 1977, she knew that Elvis Presley had died, but she also knew that a California tax initiative passed on June 6 of the following year, and a plane crashed in Chicago on May 25 of the next year, and so forth. Some may have had a personal meaning for her, but some did not.”
