It is easy to assume we crave delicious food or impulsively check email because we find pleasure in the activity. But pleasure is just half the story. Temptation is more than just the promise of reward. Recent advances in neuroscience allow us to peer into the brain, providing a greater understanding of what makes us want. In 2011, Sriram Chellappan, an?assistant professor of computer science at Missouri University of Science and Technology, gained unheard of access to sensitive information about the way undergraduates were using the Internet. His study tracked students on campus as they browsed the web. Chellappan was looking for patterns, which not only revealed what students were doing online, but provided clues about who they were. ?We believe that your pattern of Internet use says something about you,” Chellappan wrote in the New York Times. “Specifically, our research suggests it can offer clues to your mental well-being.? Chellappan concluded that there was, in fact, predictive power in the data. He found students with early signs of clinical depression used the Internet differently and he could identify students most likely to face mental health issues simply by looking at how they clicked. ?We identified several features of Internet usage that correlated with depression,? wrote Chellappan. ?For example, participants with depressive symptoms tended to engage in very high e-mail usage.” Chellappan developed the technology in hopes of creating an early-warning system to identify struggling students. But his study raised another question, why do people with depression check email more? Alleviating Pain The answer may provide clues about why all of us use the products and services we do in our everyday lives. Psychologists believe people with depression feel negative emotions, like anxiety, more frequently than other people do. There is evidence that the depressed students in Chellappan’s study were using the Internet more because they experience negative mental states more often. To try and feel better, they turned to the web to boost their mood. Finding ways to make ourselves feel better is not something only depressives do. We all seek relief from feeling bad and the brain is primed to help us learn where we can find escape. Just as we might take a Tylenol to relieve a headache, we turn to
