29、often view their childrens friends with something like suspicion.They worrythat the adolescent peer group has the power to push its members into behavior that is foolish andeven dangerous.Such wariness is well founded:statistics show,for example,that a teenage driverwith a same-age passenger in the

30、car is at higher risk of a fatal crash than an adolescent drivingalone or with an adult.B In a 2005 study,psychologist Laurence Steinberg of Temple University and his co-author,psychologist Margo Gardner,then at Temple,divided 306 people into three age groups:youngadolescents,with a mean age of 14;o

31、lder adolescents,with a mean age of 19;and adults,aged 24and older.Subjects played a computerized driving game in which the player must avoid crashinginto a wall that materializes,without warning,on the roadway.Steinberg and Gardner randomlyassigned some participants to play alone or with two same-a

32、ge peers looking on.C Older adolescents scored about 50 percent higher on an index of risky driving when their peerswere in the room-and the driving of early adolescents was fully twice as reckless when otheryoung teens were around.In contrast,adults behaved in similar ways regardless of whether the

33、ywere on their own or observed by others.The presence of peers makes adolescents and youth,but not adults,more likely to take risks,“Steinberg and Gardner concluded.D Yet in the years following the publication of this study,Steinberg began to believe that thisinterpretation did not capture the whole

34、 picture.As he and other researchers examined thequestion of why teens were more apt to take risks in the company of other teenagers,they cameto suspect that a crowds influence need not always be negative.Now some experts are proposingthat we should take advantage of the teen brains keen sensitivity

35、 to the presence of friends andleverage it to improve education.E In a 2011 study,Steinberg and his colleagues turned to functional MRI(磁共振)to investigatehow the presence of peers affects the activity in the adolescent brain.They scanned the brains of40 teens and adults who were playing a virtual dr

36、iving game designed to test whether playerswould brake at a yellow light or speed on through the crossroad.F The brains of teenagers,but not adults,showed greater activity in two regions associated withrewards when they were being observed by same-age peers than when alone.In other words,rewards are

37、 more intense for teens when they are with peers,which motivates them to pursuehigher-risk experiences that might bring a big payoff(such as the thrill of just making the lightbefore it turns red).But Steinberg suspected this tendency could also have its advantages.In hislatest experiment,published

38、online in August,Steinberg and his colleagues used a computerizedversion of a card game called the Iowa Gambling Task to investigate how the presence of peersaffects the way young people gather and apply information.G The results:Teens who played the Iowa Gambling Task under the eyes of fellow adole

39、scentsengaged in more exploratory behavior,learned faster from both positive and negative outcomes,and achieved better performance on the task than those who played in solitude.What our studysuggests is that teenagers learn more quickly and more effectively when their peers are presentthan when they

40、9re on their own,“Steinberg says.And this finding could have importantimplications for how we think about educating adolescents.H Matthew D.Lieberman,a social cognitive neuroscientist at the University of California,LosAngeles,and author ofthe 2013 book Social:Why Our Brains Are Wired to Connect,sus

41、pects thatthe human brain is especially skillful at learning socially significant information.He points to aclassic 2004 study in which psychologists at Dartmouth College and Harvard University usedfunctional MRI to track brain activity in 17 young men as they listened to descriptions of peoplewhile

42、 concentrating on either socially relevant cues(fbr example,trying to form an impression ofa person based on the description)or more socially neutral information(such as noting the order ofdetails in the description).The descriptions were the same in each condition,but people couldbetter remember th

43、ese statements when given a social motivation.I The study also found that when subjects thought about and later recalled descriptions in terms oftheir informational content,regions associated with factual memory,such as the medial temporallobe,became active.But thinking about or remembering descript

44、ions in terms of their socialmeaning activated the dorsomedial prefrontal cortex一part of the brains social network-even astraditional memory regions registered low levels of activity.More recently,as he reported in a2012 review,Lieberman has discovered that this region may be part of a distinct netw

45、ork involvedin socially motivated learning and memory.Such findings,he says,suggest that“this network canbe called on to process and store the kind of information taught in school-potentially givingstudents access to a range of untapped mental powers79J If humans are generally geared to recall detai

46、ls about one another,this pattern is probably evenmore powerful among teenagers who are very attentive to social details:who is in,who is out,who likes whom,who is mad at whom.Their desire fbr social drama is not一or not onlya wayof distracting themselves from their schoolwork or of driving adults cr

47、azy.It is actually aneurological(神经的)sensitivity,initiated by hormonal changes.Evolutionarily speaking,peoplein this age group are at a stage in which they can prepare to find a mate and start their own familywhile separating from parents and striking out on their own.To do this successfully,their b

48、rainprompts them to think and even obsess about others.K Yet our schools focus primarily on students as individual entities.What would happen ifeducators instead took advantage of the fact that teens are powerfully compelled to think in socialterms?In Social.Lieberman lays out a number of ways to do

49、 so.History and English could bepresented through the lens of the psychological drives of the people involved.One could thereforepresent Napoleon in terms of his desire to impress or Churchill in terms of his lonely gloom.Lessinherently interpersonal subjects,such as math,could acquire a social aspe

50、ct through teamproblem solving and peer tutoring.Research shows that when we absorb information in order toteach it to someone else,we learn it more accurately and deeply,perhaps in part because we areengaging our social cognition.L And although anxious parents may not welcome the notion,educators c
