Evidence #1: Passage 1 states, "Children's social skills may be declining as they have less face to face interaction due to their increased use of social media, according to a UCLA psychology study".

Kids are losing their ability to read emotions because people are only looking at technology only for educationally-wise.

Evidence #2:Passage 3 states " Many people are looking at the benefits of digital media in education and not many are looking at the costs, said Patricia Greenfield, as distinguished professor of psychology in the UCLA College and senior author of the study".

Students that don't have technology grow in lost abilities. 

Evidence #3:Passage 3 states,"The children who had been at the camp improved significantly over the five days in their ability to read facial emotions and other nonverbal cues to emotion, compared with the students who continued to use their media devices".

the end of the study, down from 14.02 at the beginning

Evidence 2: Students participating in the study reported that they text, watch television and play video games for an
average of four-and-a-half hours on a typical school day. Some surveys have found that the figure is even higher
nationally, said Uhls, who also is the Southern California regional director of Common Sense Media, a national
nonprofit organization..

Evidence 3: 14 She said the implications of the research are that people need more face-to-face interaction, and that even
when people use digital media for social interaction, they’re spending less time developing social skills and
learning to read nonverbal cues.

According to the passage”Researchers tracked how many errors the students made when attempting to identify the emotions in the photos and videos. When analyzing the photos, for example, those at the camp made an average of 9.41 errors at the end of the study, down from 14.02 at the beginning.’’ (paragraph 10)

According to the text’’“You can’t learn nonverbal emotional cues from a screen in the way you can learn it from face-to-face communication,” said lead author Yalda Uhls, a senior researcher with the UCLA’s Children’s Digital Media Center, Los Angeles’’  (paragraph 11)

According to the text”Uhls said that emoticons are a poor substitute for face-to-face communication: “We are social creatures. We need device-free time.” (paragraph 16)

 For example  phones were made in 1973 for communication purposes ,now it's used for posting information , rewarding yourself by posting , texting friends and buying things .

online.

paragraph 5 “The psychologists studied two sets of sixth-graders from a Southern California public school: 51 who lived together for five days at the Pali Institute, a nature and science camp about 70 miles east of Los Angeles, and 54 others from the same school.”
Evidence 2: 
paragraph 10 “Researchers tracked how many errors the students made when attempting to identify the emotions in the photos and videos. When analyzing the photos, for example, those at the camp made an average of 9.41 errors at the end of the study, down from 14.02 at the beginning.”
When staying away from the internet you can see the difference in the the students work. 
Evidence 3 main point:
 Paragraph 1 children’s social skills may be declining as they have less time for face-to-face interaction due to their increased use of social media, according to a UCLA psychology study.Scientists are doing an experiment to find out if 6th graders do better with or with out technology. The did communicate experiments , brain function and etc.
