14. In the Chapter Preview we presented a study show-
ing that handling money reduces the perception pain
(Zhou, Vohs, & Baumeister, 2009). In the experiment,
a group of college students was told that they were
participating in a manual dexterity study. Half of the
students were given a stack of money to count and the
other half got a stack of blank pieces of paper. After
the counting task, the participants were asked to dip
their hands into bowls of very hot water (122°F) and
rate how uncomfortable it was. The following data
show ratings of pain similar to the results obtained
in the study.
