Forget what Virginia Woolf said about
What a writer needs-a room of one’s own. The writer she had in mind wasn’t at
work on a novel in cyberspace, one with multiple hypertexts, animated graphics
and downloads of trancey, chiming music. For that you also need graphic
interfaces, ReslPlayer and maybe even a computer laboratory at Brown University.

What do consumers really want That’s a
question market researchers would love to answer. But since people don’t always
say what they think, marketers would need direct access to consumers’ thoughts
to get the truth. Now, in a way, that is possible. At the "Mind
of the Market" laboratory at Harvard Business School, researchers are looking
inside shoppers’ skulls to develop more effective advertisements and marketing
pitches. Using imaging techniques that measure blood flow to various parts of
the brain, the Harvard team hopes to predict how consumers will react to
particular products and to discover the most effective ways to present
information. Stephen Kosslyn, a professor of psychology at Harvard, and business
school professor Gerald Zaltman, oversee the lab. "The goal is not to manipulate
people’s preferences," says Kosslyn A. Reading the Mind of the Market B. Controlling the Consumers’ Preferences C. Improving the Styles of Advertising D. Finding Out the Way to Predict
