214 • CHAPTER 8 Everyday Memory and Memory Errors
The War of the Ghosts
One night two young men from Egulac went down to the river to hunt seals, and while
they were there it became foggy and calm. Then they heard war cries, and they thought:
“Maybe this is a war party.” They escaped to the shore and hid behind a log. Now canoes
came up, and they heard the noise of paddles and saw one canoe coming up to them.
There were fi ve men in the canoe, and they said:
“What do you think? We wish to take you along. We are going up the river to make
war on the people.”
One of the young men said: “I have no arrows.” “Arrows are in the canoe,” they said.
“I will not go along. I might be killed. My relatives do not know where I have gone. But
you,” he said, turning to the other, “may go with them.”
So one of the young men went, but the other returned home. And the warriors went on
up the river to a town on the other side of Kalama. The people came down to the water,
and they began to fi ght, and many were killed. But presently the young man heard one
of the warriors say: “Quick, let us go home; that Indian has been hit.” Now he thought:
“Oh, they are ghosts.” He did not feel sick, but they said he had been shot.
So the canoes went back to Egulac, and the young man went ashore to his house and
made a fi re. And he told everybody and said: “Behold I accompanied the ghosts, and we
went to fi ght. Many of our fellows were killed, and many of those who attacked us were
killed. They said I was hit, and I did not feel sick.”
He told it all, and then he became quiet. When the sun rose, he fell down. Something
black came out of his mouth. His face became contorted. The people jumped up and
cried. He was dead. (Bartlett, 1932, p. 65)After his participants read this story, Bartlett asked them to recall it as accu-
rately as possible. He then used the technique of repeated reproduction, in which
the same participants came back a number of times to try to remember the story
at longer and longer intervals after they fi rst read it. This is similar to the repeated
recall technique used in the fl ashbulb memory experiments (see Method: Repeated
Recall, page 209).
Bartlett’s experiment is considered important because it was one of the fi rst to use
the repeated reproduction technique. But the main reason the “War of the Ghosts”
experiment is considered important is the nature of the errors Bartlett’s participants
made. At longer times after reading the story, participants forgot much of the informa-
tion in the story. Most participants’ reproductions of the story were shorter than the
original and contained many omissions and inaccuracies.
But what was most signifi cant about the remembered stories is that they tended
to refl ect the participant’s own culture. The original story, which came from Canadian
folklore, was transformed by many of Bartlett’s participants to make it more consistent
with the culture of Edwardian England that they belonged to. For example, one partici-
pant remembered the two men who were out hunting seals as being involved in a sailing
expedition, the “canoes” as “boats,” and the man who joined the war party as a fi ghter
that any good Englishman would be proud of—ignoring his wounds, he continued
fi ghting and won the admiration of the natives.
One way to think about what happened in Bartlett’s experiment is that his partici-
pants created their memories from two sources. One source was the original story, and
the other was what they knew about stories in their own culture. As time passed, the
participants used information from both sources, so their reproductions became more
like what would happen in Edwardian England. This idea that memories can be infl u-
enced by the sources of information involves a phenomenon called source monitoring,
which is at the heart of the constructive approach to memory.SOURCE MONITORING AND SOURCE MONITORING ERRORS
“Did you hear about the mob scene at the movie theater for the opening of the new Harry
Potter movie?”
“Yes, I heard about it on the evening news.”
“Really? I heard about it from Bernita, who loves Harry Potter, or was it Susan? I
can’t remember.”Remember/
