Addiction
According to a study conducted by Leif Denti at the University of Gothenburg, spending time on Facebook can become addictive. Participants in the study reported that they felt ill at ease when they were not able to regularly check up on their Facebook account. With other people constantly posting new photos or status updates, people that become addicted to Facebook can feel like they are missing out if they are not constantly logged in. According to the study, these users do not even realize that they are engaged in excessive use of the service, as it becomes an unconscious habit.
