Filling in Memory

Here's a section (pages 78-80) from psychologist Dan Gilbert's great book Stumbling on Happiness about how memory works:



The preview cuts off at the bottom of page 80. Here's the rest from that section:

"...reading the words you saw. But in this case, your brain was tricked by the fact that the gist word--the key word, the essential word--was not actually on the list. When your brain rewove the tapestry of your experience, it mistakenly included a word that was implied by the gist but that had not actually appeared, just as volunteers in the previous study mistakenly included a stop sign that was implied by the question they had been asked but that had not actually appeared in the slides they saw.

"This experiment has ben done dozens of times with dozens of different word lists, and these studies have revealed two surprising findings. First, people do not vaguely recall seeing the gist word and they do not simply guess that they saw the gist word. Rather, they vividly remember seeing it and they feel completely confident that it appeared. Second, this phenomenon happens even when people are warned about it beforehand. Knowing that a researcher is trying to trick you into falsely recalling the appearance of a gist word does not stop that false recollection from happening."

Too many words, Sean! Can't you just put up a video? You better make it funny, too!

Fine. Here's Dan Gilbert on The Colbert Report:
