PITTSBURGH, May 9 (UPI) -- Virtual possessions -- digital imagery, Facebook updates, online music collections, e-mail threads -- have a powerful hold on teenagers, U.S. researchers say.
Researchers at Carnegie Mellon University say the very fact that virtual possessions are without physical form may actually enhance their value, a university release reported Monday.
"A digital photo is valuable because it is a photo but also because it can be shared and people can comment on it," said John Zimmerman, associate professor of human-computer interaction and design.
For the 21 teenagers in the CMU study, a digital photo that friends have tagged, linked and annotated was more meaningful than a photo in a frame or a drawer, the researchers found.
One study subject said she takes photos at events and uploads them immediately so she and her friends can tag and talk about them.
"It feels like a more authentic representation of the event," the 16-year-old told the researchers. "We comment and agree on everything together … then there's a shared sense of what happened."
Those in the study said they could display things online, such as a photograph of a boyfriend disliked by parents, which were important to their identity but could never be displayed in a bedroom.
In fact, the teenagers said, the online world allowed them to present different facets of themselves to appropriate groups of friends or to family.
