In a recent study carried out by psychologists on the disruptive effects of smart phones, two groups of college students were given word-search puzzles. The first group was told to complete the puzzles with its participants' smart phones in their line of sight. The second group, however, was told that the phones would interfere with the equipment in the experiment and would need be moved away from the testing area. Midway through the second group's solving of the puzzles, the experiment called one of the phones and let it ring for a while before hanging up. Many of the students in that group were unable to focus from then on, becoming anxious and performing more poorly than the first group.
在心理学家最近就智能手机的弊端展开的一项研究中，两组大学生分到了一项玩拼单词游戏的任务。第一组被告知，游戏期间，他们的智能手机要放在他们的视线之内。第二组则被告知，手机会干扰实验使用的设备，故需要将其放到测试区之外。第二组进行游戏任务期间，实验方给该组成员的一部手机打了电话，让它响了一会儿，然后挂断了电话。该组的很多同学后续都变得无法集中注意力，变得很焦虑，游戏表现也比第一组更差。
Use of electronics has also been known to lead to a decline in human interactions. Rather than having real-life conversations, many express emotions and engage in deep conversations through social media sites. Many students use their phones and computers during class for non-academic activities, which leads to poor grades. Perhaps the most dramatic impact is the reduction in amount of sleep, which lead to poor health and weight gain.
众所周知，使用电子产品还会导致人与人接触的减少。相比在现实生活中进行交谈，很多人都选择了通过社交网站表达情感或进行深入对话。许多学生还会在课堂上用手机和电脑做跟课堂无关的事情，继而出现成绩不佳的问题。最为严重的影响或许要数睡眠时间的减少，这一问题还会进一步导致健康状况不佳和体重增加。
Technology is a great tool. However, it's important to recognize its downsides. Lack of sleep, reduction of productivity, and weight gain are only a few. If we are not careful about all these mind problems right now, the effect on the future generation is going to be much bigger.
技术确实是非常不错的工具。然而，认识其缺陷也很重要。睡眠不足、生产力下降，体重增加都仅仅是很小的一部分影响。如果我们现在不小心处理所有这些心理问题，那智能手机对下一代的影响还会更加严重。
