Over at Mind Matters, there's a cool post by Fionnuala Butler and Cynthia Picketton on the benefits of watching television when lonely, which seems to provide the same sort of emotional relief as spending time with real people:
In a recent article published in the Journal of Experimental Social Psychology, Jaye Derrick and Shira Gabriel of the University of Buffalo and Kurt Hugenberg of Miami University test what they call the "Social Surrogacy Hypothesis."The authors theorized that loneliness motivates individuals to seek out relationships, even if those relationships are not real. In a series of experiments, the authors demonstrated that participants were more likely to report watching a favorite TV show when they were feeling lonely and reported being less likely to feel lonely while watching. This preliminary evidence suggests that people spontaneously seek out social surrogates when real interactions are unavailable.
