Not getting enough charitable donations? Try having people to touch sandpaper before you ask for money. A new study shows that
touching1 rough surfaces triggers the emotion of empathy, which motivates people to donate to non-profit organizations. "We found that when people were experiencing mild
discomfort2 as a result of touching a rough surface, they were more aware of discomfort in their
immediate3 environment," said Chen Wang, an assistant
marketing4 professor at Drexel University in Pennsylvania. "They could better empathize with individuals who were suffering."
Their findings are available online in the Journal of Consumer
Psychology5. In one experiment, the team tested brain activity when participants viewed painful
versus6 neutral images. In some trials the participants held an object wrapped in sandpaper -- known as haptic roughness -- while they saw the pictures. In other trials they held an object wrapped in smooth paper. The participants showed more brain activity when touching the sandpaper than the smooth paper, particularly when viewing the painful images.
In another experiment the researchers asked one group of participants to wash their hands with a smooth soap and the other with a rough, exfoliating solution. Then each group filled out questionnaires rating their willingness to donate to a charity. The group that had used the rough hand wash was more willing than the soft soap group to donate to a lesser-known foundation that supports people who suffer from Sjogren's
Syndrome7, an autoimmune disease in which the white blood cells attack the moisture-producing
glands8.
This difference between the groups did not occur when participants rated their willingness to give to the well-known National Breast Cancer Foundation. Familiarity with a charity
overrode9 the effect of haptic roughness, Wang said.
The findings could have significant implications for less well-known charities that are trying to raise money, according to the study.
"Often smaller charities invest a lot of money in
advertising10 to build
awareness11, but our data suggests that introducing haptic roughness into outreach materials could be an
innovative12 and cost-effective approach," she said.
