What’s Next for News?behave with my iPhone? Well,it’s hard to imagine a morepowerful novelty-generatingdevice. Every time it buzzesto signal a new e-mail or textmessage it is wiring even morefirmly into my brain the desireto pick up the device and lookfor that precious nugget of newinformation, which often is onlya reminder of another committeemeeting. Although noresearch has yet been publishedon this, I am confident that wesoon will see that our bond tothese devices works through thesame mechanisms in the brainthat govern addiction to drugs,food and many other things.Maximizing LearningThere is a second, relatedquestion of particular interestfor journalists. How can newsof importance be effectivelyconveyed through the digital clutterand information overload to peoplewho are in constant novelty-seekingmode? Key to figuring out how to dothis is gaining an understanding ofwhy and how the brain responds tonovelty—and then taking advantageof this knowledge in figuring outhow to attract attention. However, itis equally important to be sure thatonce information breaks through theclutter that the person receiving itremembers it.Unfortunately, our intuitions maylead us astray: Psychological researchhas shown that people are not verygood predictors of their own or others’learning. A good example of thiscomes from a study done in 2006by Henry Roediger and a graduatestudent, Jeffrey Karpicke, at Washington<strong>University</strong> in St. Louis. Usingtwo different approaches, they taughtstudents about the sun and sea ottersby giving them a paragraph containingscientific information to read abouteach topic. One group of studentshad the chance to read the materialfour times. Another group was givenThese highlighted regions in the prefrontal cortex weremore active when a person silently counted backward thanduring a rest period. The largest of them is often activewhen people engage in mental activities that place heavydemands on working memory.

Theresearchers also gave them memorytests within a few minutes after studying,as well as one week later so theywould have objective data to evaluatealong with the students’ own subjectiveevaluations.When questioned about how wellthey had learned the material, thepeople who had read the paragraphfour times indicated that they feltmuch better about their learning of thematerial. They also performed better onthe memory test right after studying.However, things were very different aweek later. At that point, people whohad studied the paragraph once andthen been tested three times handilyoutperformed the overconfidentparagraph-readers on the memorytest for the material.This kind of research is teachingus that often we can be overconfidentabout memories that arecompletely false and yet lackconfidence about our ability toremember things we have actuallylearned well. In particular,we often confuse fluency (orease) for ability. By its fourthtime reading the paragraph,that group found it very easy,and this led them to think thatit would be a snap to rememberthe material later. But it wasn’t.There is a growing body ofresearch showing that thingsthat are hardest are what makeus learn best. This concept isknown as “desirable difficulties.”If something is too easy thenwe probably aren’t learningvery much. We have more tofind out as we determine justhow widely this idea applies.But there is enough evidencealready assembled to give usreason to rethink how learningtakes place in our daily lives.The finding of desirable difficultiesposes a serious challenge to journalistsbecause things that make peopleremember best are also things thatpeople are likely to avoid because theyare difficult.As researchers learn more abouthow learning and memory work, theremay be additional clues about howto maximize learning. But there arealready some tricks that can be used.For example, information is oftenremembered better when presentedmultiple times, but only when thosedifferent times are spaced apart fromone another. Thus, presenting severalversions of an idea in different parts ofa story could help improve retention.If journalism is about learning—about taking in news and informationand understanding its relevance to ourlives—then what neuroscientists andbrain researchers are finding out aboutthe brain and its capacity to absorbinformation surely matters.

Brain PowerThinking About Multitasking: It’s What JournalistsNeed to DoHeavy media multitaskers ‘are often influenced by intervening content. Newsarticles are therefore going to require more recapitulations and reminders tohelp readers pick up where they left off.’BY CLIFFORD NASSWhen people multitask withmedia they are consumingtwo or more streams ofunrelated media content. (Dealingwith two related media streams hasdifferent dimensions.) It doesn’t matterexactly what information they aretaking in or what devices they are using;just the act of using two or moremedia streams simultaneously meansthat consumers are engaging in whatis an increasingly frequent pursuitin our digital age. Perhaps they aresearching on a Web site while textingon their phone. Or they are tuning into a YouTube video while exchanginge-mails on a laptop. Maybe CNN isplaying on their screen and they aretracking the news while chatting onlineabout work in one window andconnecting with a friend several timezones away via Skype.Or maybe all of these things arehappening at once.Given what we’re finding out aboutmedia multitasking, it is much moreubiquitous and involves many morestreams of content than is commonlyappreciated. Based on surveys we havedone at Stanford <strong>University</strong>, the averageuniversity student is regularly usingfour different media streams; fewerthan 5 percent of students report thatthey regularly use a single stream, andmore than 20 percent are using sixor more streams at one time. Otherresearch suggests that this method ofhandling media is increasing acrosspopulations ranging from infants (e.g.,breast-feeding babies will watch televisionwhen their mothers are doingso) to adults in the work force (e.g.,many companies require workers torespond immediately to multiple mediachannels, such as mobile phones, chatand e-mail).Journalists are adapting—withvarying degrees of frustration andconsternation—to the unwillingnessof the growing number of mediamultitaskers to focus on one streamof content, regardless of how engagingit might be. Given the urge toconsume as much unrelated contentas possible, readers demonstrate anunwillingness, for example, to staywith long-form journalism; the longerthe article, the greater the frequencyreaders show of bouncing around andeventually drifting to other mediastreams. Similarly, how stories arebeing told must become less complexas readers show an unwillingness toallocate enough attention to workthrough difficult material.At a more macro level, one seesincreasing concessions to heavy mediamultitaskers in the clustering of storieson the Web. In the early days of digitalnews, links would augment a storywith supporting video or prior coverageon its topic. In the second phase, thenumber of links increased, and therelationships between the story andlinks became more tenuous (e.g., having“international news” or “politics”in common). Today, numerous linkslike Top Stories, Editor’s Picks, andArticles You Might Be Interested In arescattered throughout each Web pageand the relationship between the basestory and the links tends to vanish.Heavy Media MultitaskersWhile these responses to changingreading styles are important to understand,journalists are now being confrontedwith an even more importantsituation brought about by this growthin media multitasking. Now evident tothose of us who study media multitaskingare fundamental changes in theway heavy media multitaskers (HMMs)process information. Research I didwith Eyal Ophir and Anthony Wagnerthat we published in the Proceedingsof the National Academy of Sciencesshows that HMMs—who are alreadya large and rapidly growing part ofthe population—are much worse thanprevious generations of readers atthree tasks that reporters have been<strong>Nieman</strong> Reports | Summer 2010 11
