"Imagine you could play a computer game for five
minutes each morning that would help you feel more
secure and confident in yourself. Our research
shows that people may be able to change the negative
thought patterns that sometimes produce insecurity.
We are now examining whether over time, with practice,
people can develop positive, beneficial habits of
thought to help them become more secure and
self-confident on a long term basis -- whether in
the context of their working life, their personal
relationships, or their overall sense of well being."

While this sounds like an advertising gimmick, it's actually respectable science by researchers at McGill University. According to Science News, "The team's first research results on Wham! will be published in the peer-reviewed journal, Psychological Science in July." http://www.sciencedaily.com/releases/2004/05/040507082758.htm
