These distractions are more than mere annoyances.
A study offers more insight into our struggle with distractions. It found that our brain waves pulsate (搏动) at different frequencies depending on the type of external stimuli. The rhythm is faster for automatic stimuli but slows down for tasks we consciously choose to focus on.

3 . Social network Facebook has announced that it is pausing work on Instagram Kids, a young people’s version of Instagram, the photo and video-sharing app that Facebook owns. Instagram Kids would have been for 10 to 12-year-olds, who cannot officially use Instagram because it has an age limit of 13.
However, Facebook has recently been criticized for the effect that Instagram can have on teenagers’ mental health, and in particular how girls feel about their bodies.
Facebook has since published its own research which suggests that Instagram more often has a positive effect. However, the criticism has made the company decide that now is a bad time to develop the app for people who are younger than teenagers.
Adam Mosseri, the boss of the Instagram, said that this would give the company time to listen to and work with parents, experts, public officials and politicians and to show that Instagram Kids would take into account concerns around the mental health and wellbeing of its users.
Instagram Kids has not been completely cancelled, but if it is eventually launched in the future, you’ll need a parent or guardian’s permission to sign up. There will be no advertisements and you will only be able to access “age-appropriate” photos and videos.
Mosseri said that he understood people’s worries about the project and that these steps should help the company to get things right. However, several US politicians have called on Instagram not to restart work on the app. “A pause is not enough,” said a statement from four politicians who are keenly opposed to Instagram Kids. “Facebook has completely given up the benefit of the doubt when it comes to protecting young people online and it must completely abandon this project,” the statement said.
