     We may all have had the embarrassing moment: Getting half-way through a story only to realize that we've

told this exact tale before, to the person we're boring with it now. Why do we make such memory mistakes?

     According to research published in Psychological Science, it may have to do with the way our brains

process different types of memory.

     Researchers Nigel Gopie, of the Rotman Research Institute in Toronto, and Colin MacLeod, of the University

of Waterloo, divided memory into two kinds. The first was source memory, or the ability to keep track of where

information is coming from. The second was destination memory, or the ability to recall whom we have given

information to.

     They found that source memory functions better than destination memory, in part because of the direction

in which that information is travelling.

     To study the differences between source and destination memory, the researchers did an experiment on 60

university students, according to a New York Times report. The students were asked to associate 50 random

(随意的) facts with the faces of 50 famous people. Half of the students "told" each fact to one of the faces,

reading it aloud when the celebrity's picture appeared on a computer screen. The other half read each fact

silently and saw a different celebrity picture afterward.

     When later asked to recall which facts went with which faces, the students who were giving information

out (destination memory) scored about 16 percent lower on memory perfonnance compared with the students

receiving information (source memory).

     The researchers concluded that outgoing information was less associated with its environmental context (背

景) that is, the person-than incoming information.

     This makes sense given what is known about attention. A person who is giving information even little facts,

will devote some mental resources to thinking about what is being said Because our attention is finite (有限的),

we give less attention to the person we are giving information to.

     After a second experiment with another group of 40 students, the researchers concluded that self-focus is

another factor that undermines destination memory.

     They asked half the students to continue giving out random information, while the other told things about

themselves. This time around, those who were talking about themselves did 15 percent worse than those giving

random information.

     "When you start telling these personal facts compared with non-self facts, suddenly destination memory

goes down more, suggesting that it is the self-focus component (成分) that's reducing the memory," Gopie told

Live Science.
