Passage Three

　　In a recent study carried out by psychologists on the disruptive effects of smart phones, [22] 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. [23] Many of the students in that group were unable to focus from then on, becoming anxious and performing more poorly than the first group.

　　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. [24] Perhaps the most dramatic impact is the reduction in amount of sleep, which lead to poor health and weight gain.

　　Technology is a great tool. [25] 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.
