The current generation is living in the digital age, where technology has blended with daily activity to become a way of life. Kids are operating electronic devices practically moments after being born. College students tend to take notes on laptop in class and utilize varies sources that are provided online.

From my perspective, the collaboration of technology has a negative impact on the human’s cognitive system because multitasking reduces productivity and shortens people attention span.
A recent research conducted by the University of Michigan indicates that the human brain does not multitask. In the experiment, scientists used an MRI scanner to photograph people’s mental process when performing several tasks simultaneously. The result shows that the brain has to switch among tasks, which means the brain will set the previous task aside before processing the new task. The times for switching are not obvious if the tasks are simple, but according to Weissman, even simple tasks can overwhelm the brain when they are processed together (Jon Hamilton, 2008). In her research paper “Is Multitasking Limited by a Mental Bottleneck?” Frederik Joelving reveals that the brain area which limits multitasking is the prefrontal cortex. The prefrontal cortex is the core executive of our brain, this brain region responsible for planning complex cognitive behavior, and decision-making. Researcher used...

...ercent of children had attention problem at age seven as result of watching television daily at age one to three. More research should be conducted for reliability, but base on this result, early television exposure is associated with attention problem at age seven. Therefore, society should raise attention on the negative impact of television on children.
No doubt, technology is increasingly important in modern world. Technology brings dozens of conveniences to daily life, but the side effects of these conveniences shouldn’t be ignored. Multitask is a misconception that should be carefully address and the use of digital devices such as computers and television will be distracting and decrease people’s attention. All the researches above serve as evidences to be careful with multimedia in order to inform readers on the potential negative impact of technology.
