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 same person. 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 who 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 (联想) 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 (名人的) 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 performance compared with the students receiving information (source memory).
The researchers concluded that out-going information was less associated with its environmental context (背景)---- that is, the person ---- than was 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 limited, 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.

Some years ago on a hot summer day in south Florida a little boy decided to go for a swim in the old swimming hole behind his house.In a hurry to dive into the cool water, he ran out of the back door, leaving behind shoes, socks, and shirt as he went.
He flew into the water, not realizing that as he swam toward the middle of the lake, a crocodile was swimming toward him.His mother in the house was looking out of the window and saw the two.In great fear, she ran toward the water, shouting to her son as loudly as she could.Hearing her voice, the little boy became alarmed and made a U-turn to swim to his mother.It was too late.Just as he reached her, the crocodile reached him.From the shore, the mother grabbed her little boy by the arms just as the crocodile snatched his legs.That began an incredible tug-of-war between the two.The crocodile was much stronger than the mother, but the mother was much too passionate to let go.A farmer happened to drive by, heard their screams, raced from his truck, took aim and shot the crocodile.
Remarkably, after weeks and weeks in the hospital, the little boy survived.His legs were extremely scarred by the attack of the animal.And, on his arms, were deep scratches where his mother’s fingernails dug into his flesh in her effort to hang on to the son she loved.
The newspaper reporter, who interviewed the boy, asked if he would show him his scars.The boy lifted his legs.And then, with obvious pride, he said to the reporter, “But look at my arms.I have great scars on my arms, too.I have them because my Mom wouldn’t let go.”
Never judge another person’s scars, because you don’t know how they were made.

In our culture, the sources of what we call a sense of “mastery”— feeling important and worthwhile — and the sources of what we call a sense of “pleasure”— finding life enjoyable — are not always the same.Women often are told “You can’t have it all.” Sometimes what the speaker really is saying is: “You choose a career, so you can’t expect to have closer relationships or a happy family life.” or “You have a wonderful husband and children — what’s all this about wanting a career?” But women need to understand and develop both aspects of well-being, if they are to feel good about themselves.
Our study shows that, for women, well-being has two aspects.One is mastery, which includes self-respect, a sense of control over your life, and low levels of anxiety and depression.Mastery is closely related to the “doing” side of life, to work and activity.Pleasure is the other aspect, and it is made up of happiness, satisfaction and optimism.It is tied more closely to the “feeling” side of life.The two are independent of each other.A woman could be high in mastery and low in pleasure, and vice versa(反之亦然).For example, a woman who has a good job, but whose mother has just died, might be feeling very good about herself and in control of her work life, but the pleasure side could be damaged for a time.
The concepts of mastery and pleasure can help us identify the sources of well-being for women, and correct past mistakes.In the past, women were encouraged to look only at the feeling side of life as the source of all well-being.But we know that both mastery and pleasure are important.And mastery seems to be achieved largely through work.In our study, all the groups of employed women were valued significantly higher in mastery than women who were not employed.
A woman’s well-being is developed when she takes on multiple roles.At least by middle adulthood, the women who were involved in a combination of roles — marriages, motherhood, and employment — were the highest in well-being, in spite of warnings about stress and strain.
