One of the first formal studies
of the phenomenon
was at Harvard Medical School
in the year 2000.
Participants played the
game for seven hours each,
spread over the
course of three days.
Remarkably, 63 percent
of the participants,
almost two thirds,
reported seeing imagery
from the game
hours after they
finished playing,
often just as they
were falling asleep.
This fact on its
own was newsworthy.
But even more surprising,
amnesic patients with brain
damage that prevents them
from forming new memories
also reported seeing
game imagery
well after they'd
finished playing.
These participants were unable
to recall having ever played the
game, but their descriptions
matched those of players with
perfect memories.
Blocks, they all saw blocks,
falling from space,
sometimes rotating or fitting
neatly into empty spaces
between other blocks.
Some participants also
reported seeing completed lines
disappearing.
