No­ti­fi­ca­tion dis­trac­tion

Down to Earth - - SCIENCE -

EN­ERGY USE has fast out­paced pop­u­la­tion growth dur­ing the past few 100 years, with each gen­er­a­tion pro­duc­ing more en­ergy per per­son than its pre­de­ces­sor. A study quan­ti­fied the re­la­tion­ship be­tween hu­man pop­u­la­tion growth and en­ergy use on an in­ter­na­tional scale and found that the dy­nam­ics changed af­ter 1963, when the world's pop­u­la­tion started grow­ing faster than ever be­fore. The ra­tio be­tween en­ergy in­creases and pop­u­la­tion growth has nar­rowed, with the for­mer now align­ing more closely to the lat­ter. The study also found that per capita en­ergy yields fluc­tu­ated dur­ing times of so­cio-eco­nomic and en­vi­ron­men­tal up­heaval: the Lit­tle Ice Age, the In­dus­trial Revo­lu­tion, World War I and II, the oil crises of the 1970s. This sug­gests that ef­forts are needed to in­crease the re­li­a­bil­ity of fu­ture en­ergy yields to sta­bilise pop­u­la­tion growth and the global so­cioe­co­nomic sys­tem. PLoS One, June 19 US­ING A mo­bile phone while per­form­ing an­other task is as­so­ci­ated with poorer per­for­mance. That's be­cause peo­ple have lim­ited ca­pac­ity for at­ten­tion that must be split be­tween tasks. Now a new study says that even cell phone no­ti­fi­ca­tions can af­fect your at­ten­tion per­for­mance. Par­tic­i­pants of the study who re­ceived no­ti­fi­ca­tions made three times more mis­takes on a com­puter task than those who didn't.
