Living in the 21st century requires keeping up to date with the latest technological advances. Since the development of social networking sites, people are now able to create a carefully crafted identity for themselves. This has led psychologists to wonder how well these online personas match the person in front of the computer. The innovative branch of media psychology studies how social networks represent individuals and initiate human interactions within a society. A fundamental question is to what extent are people able to know each other through social networking sites? In a research study, Psychster Inc. explored the characteristics of profile photos and their association with impression. Using a specially designed social networking site, http://www.YouJustGetMe.com, Psychster analyzed 1,316 first impressions from profile owners who had posted photographs as part of a full profile (Steele , Evans and Green, 2008). The results suggested that photographs in which profile owners were smiling, outdoors, and shown with others were associated with higher impression agreement. Some findings implied that other aspects of photographs, such as headgear and weight, also affected impression concordance based on the gender of the profile owner (Steele, Evans, & Green, 2008). Overall, this research suggests that visitors to online profiles are likely to view the profile owners in the same way that the owners view themselves, even if they have never met before. In another study, psychologist Samuel Gosling of the University of Texas measured the correlation between active and deactivated personality. line of 133 undergraduate students with Facebook profiles. Gosling found that students' personalities were accurately represented online, unlike the middle of a sheet of paper or 1,000 words?
