Parents Who Set Limits on Tech Use Have Smarter, Healthier Kids

What's the Latest?


Parents can encourage better study habits and healthier lifestyles by limiting the amount of time their children spend in front of a screen. From TVs and laptops to tablets and smartphones, screen time trades off with other valuable activities, according to a study of over 1,300 3rd to 5th graders. "Reducing total screen time increases children’s amount of sleep, which in turn lowered their weight gain.  Reducing total screen time also led to higher school performance, more prosocial behavior, and lower aggressive behavior." Reducing media violence also resulted in more prosocial behavior.

What's the Big Idea?

Due to the emergence of different kinds of media and different kinds of media platforms, most researchers think in terms of "total screen time." So rather than limiting the amount of time a child spends watching TV, parents are encouraged to consider all the entertainment hours spent before TV, DVDs, iPad, Facebook, and video games. "[T]he American Academy of Pediatrics...recommend that elementary school children spend no more than one hour of total screen time a day, and no more than two hours a day for secondary school children."

  • If men fought other men, winners would have survived and reproduced, losers not so much.

Study: Private prisons result in more inmates, longer sentences

The Labour Economics study suggests two potential reasons for the increase: corruption and increased capacity.

Politics & Current Affairs
  • After adopting strict sentencing laws in the '80s and '90s, many states have turned to for-profit prisons to handle growing prison populations.
  • A new study in Labour Economics found that privately-run prisons correlate with a rise in incarceration rates and sentence lengths.
  • While evidence is mixed, private prisons do not appear to improve recidivism or cost less than state-run facilities.
