Influencing Others in Business Environments

Throughout human civilization, the art of selling ideas or products has
been a cornerstone of society. Some people have become masters at this art,
yielding themselves and their companies large amounts of profit. Why is it that
some people are better at this than others? This paper will take a look at the
various aspects of nonverbal communication in selling (or influencing others to
buy) and in job interviews by examining in detail the various aspects of
proximics, haptics, physical attractiveness, and other nonverbal cues that
influence people to say yes.

Artifacts and local environment

Several studies have presented evidence in support of the theory that
"dressing for success" affects one\'s ability to influence other people. One
study found that people dressed in suits versus people dressed in casual or
working-class clothes actually affects a subject\'s likelihood of answering a
question correctly. In this study, a person dressed in a suit had a 77% percent
chance of getting money returned to them, while those dressed casually or in
working outfits had a 38% chance (Bickman, 1971). This study suggests that a
person\'s status affects how well they are received by the person they are trying
to influence, and thus their likelihood of being able to influence them into
buying an idea or product.
Seating arrangements can affect ones ability to influence others.
Seating arrangements that are closer to one another have a greater effect and
lead to a less hostile environment than when people are seated opposite of one
another (Sommer, 1967). Sommer found that when a relationship is of a
competitive nature (i.e. bargaining situations such as labor contract
agreements) there is a preference for this style of seating because it "reflects
a desire to obtain information about one\'s competitor." Another study suggested
round tables help to "increase informality and feelings of closeness in
comparision to square or rectangular tables" (Sommer, 1965). Dawson (1986)
suggested having the members of the negotiation dispersed, that is, have
intermixing the opposing members together helps smooth over negotiations.
Placing artifacts in the negotiating environment can have affects on the
negotiation. A flower, vase, or abstract artwork have a tendency to promote
informality and affiliative behavior while books and magazines placed in the
environment discourage these processes (Mehrabian, 1971).

Voice and Tone

Voices have a significant persuasive affect. A study by Mehrabian and
Williams (1969) suggested that there are four nonverbal cues of voice that have
a persuasive effect. These are: having a louder amplitude, having a greater
intonation, having greater fluency in speech, and having a faster tempo during
speaking. Another study showed that when one has a louder and more fluent voice
they were more likely to get a favorable decision on a job interview or in a
legal battle (Hollandsworth et al., 1979). Faster tempos have a more persuasive
affect by exhibiting expertise and competence (Buller, 1986). But, there is a
limit. Speaking tempos greater than 375 syllables per minute decrease their
persuasive affect with faster tempos exhibiting greater and greater levels of
loss of persuasiveness.

Physical Appearance

Phsyical apperance has several manners in which it can help or hinder
the outcome of a negotiation. Raw physical attractiveness, one\'s innate or
genetic attractiveness, has been shown to dramatically affect the attentiveness
of an audience. One study did an experiment with a woman, first she was dressed
to look unattractive, then she was dressed attractively. The study showed that
among male audience members her ability to influence them varied with how well
she dressed. When she was dressed well, she was seen as more persuasive than
when she was dressed unattractively (Mills & Aronson, 1965). Another study
between a middle aged male professor and a younger attractive male undergraduate
yielded some interesting results. The study showed that among a female
audience, the young male was seen as persuasive with or without evidence to
support his theories; whereas, the male professor was only seen persuasive with
evidence (Norman, 1976). All of these studies suggest that the persuasive
affect of attractiveness is most significant with the opposite sex. That is,
the persuasive effect of attractiveness only works when the audience members
being influenced are not of the same sex as the speaker. Why is this so?
Bettinghaus and Code (1987) offer this answer: "Attractive sources influence us
because of their attractiveness, not because of message content. That is, since
we identify with, and desire approval from, attractive sources, we respond to
them, not the messages)."

Listening and Silence

Listening (or silence) is another key and often under-rated aspect of
effective nonverbal behavior. While most people think they know how to listen,
few can do it well (Churchman, 1993). One cliche
