The Nightmare Of Total Recall, Ctd.

Jonah Lehrer recalls:

This isn't the first case report of a person with perfect memory. In the masterful The Mind of A Mnemonist, the Soviet neurologist A.R. Luria documented the story of a Russian newspaper reporter, D.C. Shereshevskii, who was incapable of forgetting.

For example, D.C. would be bound by his brain to memorize the entire Divine Comedy of Dante after a single reading. Audiences would scream out random numbers 100 digits long and he would effortlessly recount them. The only requirement of this man's insatiable memory was that he be given 3 or 4 seconds to visualize each item during the learning process. These images came to D.C. automatically.

Eventually, D.C.'s memory overwhelmed him. He. struggled with mental tasks normal people find easy. When he read a novel, he would instantly memorize every word by heart, but miss the entire plot. Metaphors and poetry - though they clung to his brain like Velcro - were incomprehensible. He couldn't even use the phone because he found it hard to recognize a person's voice "when it changes its intonation...and it does that 20 or 30 times a day."
