Computers，smartphones，and audio players are an essential part of students' everyday lives.That means that whenever students are doing homework，they are going to be faced with the problem of using their devices for purposes other than learning.Instead of concentrating on one task，they are performing multiple tasks.
    According to the research by Larry Rosen，published in the journal Computers in Human Science，students spend up to 45% of their homework time on various tasks unrelated to their studies.Students often get distracted（分神）by their phones or use their laptops for unauthorized （未经许可的）activities.
    Often，students think that they are able to multitask effectively，without sacrificing their studies.However，the research shows that it is true in only 5% of all cases.
    But why do teenagers multitask？The answer is simple：multitasking makes us feel good.As the research indicates，the entertainment gained from secondary activities during studies makes learners feel better emotionally.Watching TV or talking to your friends by email is pleasant and helps students fight boredom while doing homework or listening to a lecture they find boring.Another reason why students multitask is that they simply do not see the negative impact it has on their coursework.Teenagers often overrate their abilities.The seemingly tiny distractions，however，result in a constant need to switch focus and sort out information，injuring the brain by overuse and making the process inefficient.
    However，the effects of multitasking are not entirely negative.The research conducted by HKU indicates that people who routinely multitask are able to use their senses in conjunction （结合）more easily.Other research also shows that multitasking has a positive effect on the ability to pass judgment and solve problems quickly and efficiently.
