You 'see' far more in a glance than you can ever report seeing

In 1960, George Sperling flashed a grid of 12 letters for just 50 milliseconds. Asked to recall the whole grid, people could name only about a third of the letters. But cued to report just one row right after the flash, they got nearly all of it — proving every letter had briefly registered. That fast-fading visual buffer, later named iconic memory, decays in under half a second.
