How is twitter hurting students? One might find it odd that a social network like twitter can hurt a student, but studies performed by Dr. Alloway says that because of the way its stream is formatted it doesn’t engage the students brain. Dr. Tracy Alloway of Scotland’s University of Stirling studies the working memory and has developed a training program to increase the performance of children ages 11-14 who are slow learners. She has found that twitter does not engage the children’s brain enough and it reduces their attention span. Twitter is a social network that has an endless stream of status updates that you do not have to read or keep track of. Therefore, you don’t have to process any information. On the other hand, Facebook does the total opposite Dr. Alloway states, Facebook keep the brain engaged because it requires you to keep up with past events, present and future.
