Passage FourLetting it out may be bad for your emotional health. Many people assume that sharing feelings openly and often is a positive ideal that promotes mental health. But some social critics and psychologists now conclude that repressing one’s feelings may do more good than venting emotions."A small number of researchers are taking an empirical look at the general assumption that speaking out and declaring one’s feelings is better than holding them in," writes Christina Sommers, a resident fellow at the American Enterprise Institute.At Suffilk University, psychologist Jane Bybee classified high-school students on the basis of their self-awareness: "sensitizers" were extremely aware of their internal states, "repressors" focused little on themselves, and "intermediates" occupied the middle range. Bybee then collected Student evaluations of themselves and each other, along with teacher evaluations of the students. On the whole, the repressors were more socially and academically successful than their more "sensitized" classmates. Bybee speculated that repressed people, not emoters, may have a better balance of moods.In a study at Catholic University in Washington, D.C., researcher George Bonanno tested the assumption that, in order to recover mental health, people need to vent negative emotions by discussing their feelings openly. Bonanno and other researchers found that, among adolescent girls who had suffered sexual abuse, those who "showed emotional avoidance" were healthier than those who more openly expressed grief or anger.One study of Holocaust survivors supports Bonanno in suggesting that verbalizing strong emotions may not improve a person’s mental health. Researchers found that Holocaust survivors who were encouraged to talk about their experiences in the war fared worse than repressors. They concluded that repression was not pathological response to Holocaust experience and that "talking through" the atrocities failed to being closure to the survivors.Sommers note that in many societies it has been considered normal to repress private feelings, and that "in most cultures stoicism and reticence are valued, while the free expression of emotions is deemed a personal shortcoming." She is concerned that pushing someone to be "sensitizers" may also create a preoccupation with self that excludes outside interests. Sommers is particularly critical of educational approaches that attempt to encourage self-discovery and self-esteem through excessive "openness".Healthy stoicism should not be confused with the emotional numbness that may be brought on by post-traumatic stress disorder. Most people experiencing such traumas as war, assault, or natural disaster can benefit from immediate counseling, according to the National Institute of Mental Health. According to Jane Bybee, "sensitizers" were （）.
41. ______The number and variety of courses on offer these days makes it difficult to pick the right one. But thousands of Europeans who flock to Brussels Exhibition Centre will be shown how to simplify the difficult job of choosing the right course of study for the career they wish to pursue.42. ______Ten years ago a handful of Belgian teenagers, baffled by the array and number of university courses on offer, put their heads together to try to hack their way through the academic undergrowth. They knew that choosing the wrong subject or failing to make the grade would make finding a job all the more difficult. They decided something had to be done to help students approach the task of choosing a course in an effective way. They came up with the idea of a Student Fair.43. ______It was decided that this would take the form of a small forum for everyone in Belgium involved in higher education from both the French and Dutch-speaking parts of the country. It would provide the opportunity for representatives of educational institutions to give information on the courses they have on offer and allow school-leavers time to discuss these with them.44. ______But what the youngsters did not know was that they were tapping a source of anxiety among students right across Europe. The fair became an annual event. It expanded to include higher education bodies from the whole continent, becoming known as the European Student Fair.45. ______"Each year ten million students are faced with the same dilemma," said exhibition organizer Valerie de Norre. "The bewildering variety of options, the evolution of the employment market, the economic downturn, changes in working methods and personal interests all play an important role in the decision-making process. We hope the fair can help people make the correct decision for themselves."This year the theme of the fair is "the right to education for all" and to mark this there is a special exhibition area for bodies that promote equal opportunities in education. Also, the Master of Business Administration course continues to attract an enormous amount of interest across Europe and, in response to demand, fair organizers are once again holding an MBA day. 42（）
