The Internet has developed and evolved over the last forty years, making the world, as we know it, a smaller place. With advances in communications and a variety of social networking sites (SNS; for definition and history see Boyd & Ellison, 2007), the restrictions can be limitless. The use of SNS, for example Facebook, has been integrated into the daily routine. Longwood University suggests that Facebook has brought great innovation to our society, such as worldwide communication at your fingertips, keeping in touch with old/new friends and social news updates, etc. However, SNS has a dark side and most people are affected by its negative behavioral impact. I will examine a psychological overview of many negative cognitive behaviors in adolescents, as a result of excessive SNS use via Facebook. As quoted in May 2010, Mark Zuckerberg told Time reporter Dan Fletcher that Facebook's mission was to build a Web where "the default is social" to "make the world more open and connected." Facebook was created so carefully using “invisible algorithms and protocols to control the visibility of friends, news, articles or ideas” thus keeping the user interested and connected for longer. As one might read this as a positive statement, there are many psychological consequences negative, such as addiction. Research indicates from Wilson et al. (2010) that low self-esteem has amplified the addictive process of adolescents who repeatedly access SNSs , MW (2013), when self-esteem is low, confidence and motivation are minimal in adolescent behavior. Consequently, addiction to SNS access causes an increase in self-esteem, i.e., confidence and motivation. Also...... half of the paper...... University Press.12 - Eyesenck, M.W. (2013).
