Once upon a time, the only ideologically acceptable explanations of mental differences between men and women were cultural. Any biologist who dared to suggest in public that perhaps evolution might work differently on the sexes, and that this might perhaps result in some underlying neurological inequalities, was likely to get tarred and feathered. Today, by contrast, biology tends to be an explanation of first resort in matters sexual. So it is salutary to come across an experiment which shows that a newly discovered difference which fits easily, at first sight, into the biological-determinism camp, actually does not belong there at all.
Writing in Psychological Science, a team led by Ian Spence of the University of Toronto describes a test performed on people's ability to spot unusual objects that appear in their field of vision. Success at spatial tasks like this often differs between the sexes (men are better at remembering and locating general landmarks; women are better at remembering and locating food), so the researchers were not surprised to discover a discrepancy between the two. The test asked people to identify an “odd man out” object in a briefly displayed field of two dozen otherwise identical objects. Men had a 68% success rate. Women had a 55% success rate.
Had they left it at that, Dr. Spence and his colleagues might have concluded that they had uncovered yet another evolved difference between the sexes, come up with a “Just So” story to explain it in terms of division of labour on the African Savannah, and moved on. However, they did not leave it at that. Instead, they asked some of their volunteers to spend ten hours playing an action-packed, shoot-'em-up video game, called Medal of Honour: Pacific Assault. As a control, other volunteers were asked to play a decidedly non-action-packed puzzle game, called Ballance, for a similar time. Both sets were then asked to do the odd-man-out test again.
Among the Ballancers, there was no change in the ability to pick out the unusual. Among those who had played Medal of Honour, both sexes improved their performances. That is not surprising, given the different natures of the games. However, the improvement in the women was greater than the improvement in the men—so much so that there was no longer a significant difference between the two. Moreover, that absence of difference was long-lived. When the volunteers were tested again after five months, both the improvement and the lack of difference between the sexes remained. Though it is too early to be sure, it looks likely that the change in spatial acuity—and the abolition of any sex difference in that acuity—induced by playing Medal of Honour is permanent.
That has several implications. One is that playing violent computer games can have beneficial effects. Another is that the games might provide a way of rapidly improving spatial ability in people such as drivers and soldiers. And a third is that although genes are important, upbringing matters, too. In this instance, exactly which bit of upbringing remains unclear. Perhaps it has to do with the different games that boys and girls play. But without further research, that suggestion is as much of a “Just So” story as those tales from the savannah.

1. The “odd man out” object in the experiment of Ian Spence refers to _____.
[A] a weird man
[B] the different object
[C] an ugly guy
[D] something separated from others
1. 在Ian Spence的試驗中,“孤立的物體”指的是 _____。
[A] 奇怪的人
[B] 不同的物體
[C] 丑陋的人
[D] 單個的物體
答案:B 難度系數(shù):☆☆☆☆
分析:推理題。根據(jù)第二段:The test asked people to identify an “odd man out” object in a briefly displayed field of two dozen otherwise identical objects. 是要求試驗對象找出和其他物體不同的物體;第一段提到了要找出unusual object,因此,選項B為正確答案。
2. In Ian Spence's experiment, the fact that men had higher success rate of identifying the “odd man out” object proves _____.
[A] the biological-determinism is universal because men are better at remembering general landmarks than women
[B] the conclusion that women are of no difference with men in terms of judging objects
[C] it is an accepted conclusion that men have higher success rate at spatial tasks than women
[D] the biological discovery that men are genetically more intelligent than women
2. 在Ian Spence的試驗中,男性在辨認(rèn)不同物體方面的成功率比女性高說明了 _____。
[A] 生物決定論是普適的,因為男性在記憶地標(biāo)這方面比女性要強
[B] 女人在判斷物體方面與男人沒有區(qū)別的結(jié)論
[C] 一個已經(jīng)被接受的結(jié)論,即男性在完成空間任務(wù)方面比女性有更高的成功率
[D] 男性比女性更聰明的生物學(xué)發(fā)現(xiàn)
答案:B 難度系數(shù):☆☆☆
分析:細(xì)節(jié)題。根據(jù)第二段,選項A和C的表述是已有的結(jié)論:men are better at remembering and locating general landmarks; women are better at remembering and locating food,即從辨認(rèn)不同物體方面的能力來看,男性的能力優(yōu)于女性。選項D文章中沒有提及,而且其表述顯然也是錯誤的。文章第三段和第四段在描述試驗結(jié)果時指出了:Had they left it at that, Dr. Spence and his colleagues might have concluded that they had uncovered yet another evolved difference between the sexes. 但是Among the Ballancers, there was no change in the ability to pick out the unusual. Among those who had played Medal of Honour, both sexes improved their performances. 可見,男女之間的差別是不大的,因此,答案為B。
3. The word “control” (Line 5, Paragraph 3) most probably means _____.
[A] contrast
[B] regulation
[C] monitor
[D] manipulation
3. control這個詞(第三段第五行) 最有可能的意思是 _____。
[A] 對比
[B] 規(guī)范
[C] 監(jiān)控
[D] 操縱
答案:A 難度系數(shù):☆☆
分析:推理題。根據(jù)上下文:As a control, other volunteers were asked to play a decidedly non-action-packed puzzle game, called Ballance, for a similar time. 說明這兩個游戲是兩種不同的游戲,作者這樣做是為了有一個控制組與另外一組進(jìn)行參照和對比,因此,選項A為正確答案。
4. Which one of the following case is NOT true of game players' performances of identifying the “odd man out” object?
[A] There was no difference between men and women in identifying the “odd man out” object after playing the violent game.
[B] Women exceeded men at picking out the unusual object than men after playing the violent game.
[C] Men were the same as women at picking out the unusual object after playing Balance.
[D] Women were more greatly improved in identifying the “odd man out” object after playing Medal of Honor than men.
4. 關(guān)于志愿者們辨認(rèn)不同物體的表現(xiàn),下列哪項陳述是錯誤的?
[A] 玩完暴力游戲后,男性和女性在辨認(rèn)不同物體方面沒什么差別。
[B] 女性在玩完暴力游戲后,選出不同物體的能力比男性更強。
[C] 玩完《平衡》游戲后,男性和女性選出不同物體的能力是相同的。
[D] 女性在玩完《榮譽勛章》游戲后,辨別不同物體的能力增強的程度比男性要高。
答案:B 難度系數(shù):☆
分析:細(xì)節(jié)題。根據(jù)第四段:Among the Ballancers, there was no change in the ability to pick out the unusual. Among those who had played Medal of Honour, both sexes improved their performances. 以及However, the improvement in the women was greater than the improvement in the men—so much so that there was no longer a significant difference between the two. 即玩完暴力游戲后,女性辨認(rèn)不同物體的能力跟男性差不多,她們提高的程度大,因此,選項B是錯誤的,是正確答案。
5. From the game experiment by Ian Spence, the following conclusions can be drawn that _____.
[A] violent games should be widely promoted to improve people's ability of remembering and locating general landmarks
[B] the reason that boys have better spatial ability is mainly because they play much more violent games
[C] genes in determining the spatial ability can be changed by acquired practice
[D] playing violent games could change people's congenital ability
5. 從Ian Spence的游戲試驗中,可以得出以下結(jié)論 _____。
[A] 應(yīng)該大力普及暴力游戲,從而提高人們記憶和確定大路標(biāo)的能力
[B] 男孩的空間能力比較強,是因為他們玩更多的暴力游戲
[C] 空間能力可以通過后天習(xí)得來改變
[D] 玩暴力游戲可以改變?nèi)藗兊南忍炷芰?br />
答案:C 難度系數(shù):☆☆☆☆
分析:細(xì)節(jié)題。選項C,能力可以通過后天的培養(yǎng)來改變,因此該選項是正確的。選項A顯然不正確,因為文章中沒有提到violent games should be widely promoted。選項B也在文章的最后一段中有所暗示,即:Perhaps it has to do with the different games that boys and girls play. 但這只是一個猜測,不是定論。選項D更是明顯錯誤的結(jié)論。因此,正確答案為C。
過去,關(guān)于男性和女性的思想之間存在的差別,唯一可以為人所接受的解釋就是文化。如果有誰敢于公開宣稱進(jìn)化有可能在男女身上起到了不同的作用,并稱這可能導(dǎo)致了神經(jīng)方面的不平等,這樣的人可能會受到重罰。現(xiàn)在情況正好相反,生物學(xué)可能會成為性別差異的首選解釋。因此,當(dāng)一項試驗發(fā)現(xiàn)的一種差異第一眼看來和絕對論陣營一致,而實際上并非如此時,這是值得慶賀的。
據(jù)《心理科學(xué)》報道,多倫多大學(xué)的Ian Spence領(lǐng)導(dǎo)一個小組進(jìn)行了一項實驗,旨在研究人們發(fā)現(xiàn)視野中出現(xiàn)的異物的能力。男性和女性在這種空間實驗中的表現(xiàn)往往有差別(男性在記憶和確定路標(biāo)方面表現(xiàn)更優(yōu);女性在記憶和找出食物的位置方面表現(xiàn)更好),因此研究者發(fā)現(xiàn)了性別之間的差異,他們對此絲毫不感到驚訝。該實驗要求人們在放置有24個相同物體的展示臺上辨認(rèn)出“孤立的物體”。男性的正確率為68%,而女性的正確率為55%。
如果實驗到此為止,那么Spence博士和他的同事就可以得出結(jié)論,認(rèn)為他們發(fā)現(xiàn)了性別之間的另外一種差異,用一個“也就是如此”的故事來解釋非洲大草原上的勞動分工,然后繼續(xù)。但是他們卻沒有這樣做。他們讓一些志愿者花十個小時玩一種叫做《榮譽勛章:太平洋攻擊》的情節(jié)火爆的射擊視頻游戲。參照組的志愿者則玩一種名為《平衡》的情節(jié)平淡的拼圖游戲,也玩十個小時。然后讓兩組人一起再做“孤立物體”實驗。
玩《平衡》游戲的志愿者在“孤立物體”實驗中的前后表現(xiàn)沒有什么變化。而玩《榮譽勛章》的志愿者中,無論男性還是女性的表現(xiàn)都有所提高。這一點都不奇怪,因為游戲的性質(zhì)有別。但是,女性能力提高的幅度要比男性的大,以至于最后兩者之間已經(jīng)沒有明顯的差別了。而且,這種差異的消失一直都會存在。五個月后,志愿者們又接受了一次測試,他們能力的提高與性別之間的無差別還保持不變。盡管現(xiàn)在下結(jié)論還為時尚早,但是因為玩《榮譽勛章》游戲引起的空間敏度差別,以及該敏度上男女性別之間差別的消失是一直不變的。
這個結(jié)論有幾個意義。其中一個意義是,玩暴力電腦游戲會有一些好的效果。另外一個意義是,該游戲可能提供了一種快速提高人們(如司機和士兵)空間能力的方法。第三個意義是,雖然基因很重要,但是后天的培養(yǎng)也很重要。在這個例子中,具體是哪些后天因素引起了能力的改變還不明確。也許這與男孩女孩玩的不同游戲有關(guān)。由于沒有進(jìn)行進(jìn)一步的研究,這種建議也只是“僅此而已”的故事罷了,這和大草原上的那些故事并沒有什么兩樣。
