                                                                 Pacing and Pausing

     Sara tried to befriend her old friend Steve's new wife, but Betty never seemed to have anything to say.

While Sara felt Betty didn't hold up her end of the conversation, Betty complained to Steve that Sara never

gave her a chance to talk. The problem had to do with expectations about pacing and pausing.

     Conversation is a turn-taking game. When our habits are similar, there's no problem. But if our habits

are different, you may start to talk before I'm finished or fail to take your turn when I'm finished. That's

what was happening with Betty and Sara.

     It may not be coincidental that Betty, who expected relatively longer pauses between turns, is British,

and Sara, who expected relatively shorter pauses, is American. Betty often felt interrupted by Sara. But

Betty herself became an interrupter and found herself doing most of the talking when she met a visitor

from Finland. And Sara had a hard time cutting in on some speakers from Latin America or Israel.

     The general phenomenon, then, is that the small conversation techniques, like pacing and pausing, lead

people to draw conclusions not about conversational style but about personality and abilities. These habitual

differences are often the basis for dangerous stereotyping (思维定式). And these social phenomena can

have very personal consequences. For example, a woman from the southwestern part of the US went to live

in an eastern city to take up a job in personnel. When the Personnel Department got together for meetings,

she kept searching for the right time to break in-and never found it. Although back home she was considered

outgoing and confident, in Washington she was viewed as shy and retiring. When she was evaluated at the

end of the year, she was told to take a training course because of her inability to speak up.

     That's why slight differences in conversational style-tiny little things like microseconds of pause-can have

a great effect on one's life. The result in this case was a judgment of psychological problems-even in the mind

of the woman herself, who really wondered what was wrong with her and registered for assertiveness

training.
