问题     It turns out you can size up personality just by looking at a person’s Facebook profile. While that may not seem like a big deal, it is providing fodder for academics who are trying to predict temperament based on the things we post online. If such predictions prove accurate, employers may have good reason to poke around our Facebook pages to figure out how we would get along with others at the office. And Pentagon officials want to use personality assessments to make better decisions on and off the battlefield.
    A recent study by researchers at the University of Maryland predicted a person’s score on a personality test to within 10 percentage points by using words posted on Facebook. " Lots of organizations make their employees take personality tests," said Jennifer Golbeck, an assistant professor of computer science and information studies at the University of Maryland. "If you can guess someone’s personality pretty well on the Web, you don’t need them to take the test. "
    Golbeck and her colleagues at the university’s Human-Computer Interaction Lab—where she’s the co-director—surveyed the public profiles of nearly 300 Facebook users this year. They looked at users ’ descriptions of their favorite activities and membership in political organizations. They also looked at Facebook’s public "About Me" and "Blurb" sections.
    The 300 participants then took a standard psychological exam that measures the "big five" personality traits: openness to experience, conscientiousness, extroversion, agreeableness and neuroticism.
    People who tested as extroverts on the personality test tended to have more Facebook friends, but their networks were more sparse than those of neurotics, meaning that their friends were less likely to know one another than were the friends of other Facebook users. People who tested as neurotic had more " dense" networks of people who know one another and share similar interests.
    The researchers also found that people with long last names tended to have more neurotic traits, perhaps because "a lifetime of having one’s long last name misspelled may lead to a person expressing more anxiety and quickness to anger," according to the study. People who tested high on the neurotic scale also tended to use a lot of anxiety-associated words, such as "fearful" and "nervous" , on their Facebook posts. They also use words describing ingestion: "pizza" , "dish" , "eat".
    Golbeck says she can’t explain that last correlation. "You’d have to get a psychologist on that one," she said. "It could be that people that are neurotic talk more about what they are eating. It could be a deep correlation that we can’t understand on the surface. "
Golbeck and her colleagues used the following research methods EXCEPT______.
选项 A、investigating the candidates’ membership in political organizations
B、probing into the candidates’ descriptions of their hobbies
C、studying some contents posted on Facebook’s public sections
D、examining the candidates on their psychological characteristics
答案A
解析 细节题。由题干中的Golbeck and her colleagues和research methods定位至第三段和第四段。第三段第二句提到，研究者调研了实验参与者对其最喜欢的活动和政治组织会员身份的描述，而不是直接调查他们在这些组织中的会员资格，故答案为[A]。第三段第二句提到实验对象对其喜欢的活动的描述，可以概括为对爱好的描述，故排除[B]；而第三段末句指出，研究者还调研了Facebook公共板块的部分内容，故排除[C]；第四段提到实验对象参加了标准的性格心理测试，故也应排除[D]。
