A study showed that participants who suffered from clinical depression exhibited less left frontal lobe activity than right, while, conversely, characteristically good-natured participants exhibited greater left lobe activity. Thus one's general disposition is a result of the activity of one's frontal lobe.
Each of the following, if true, weakens the argument except:
正确答案是(A), Many drugs prescribed to combat clinical depression act by causing increased left lobe activity. 但不太明白这个为什么不对，是说这些药品可能不能有效combat depression吗？作者: s_dUSA 时间: 2012-7-7 14:44
pay attention to the question, it's ask non-weakening item!
A is strengthening the argument, sure it is the correct answer!作者: 玛莎丁丁 时间: 2012-7-8 22:23
A的意思是说由于大多数抗抑药物是通过增加那个left lobe活动而产生效果，所以可能可以用来佐证这个研究的结论，也即个人个性与大脑物理活动之间的关系。。。虽然个人认为不一定有力地strengthen，但确实不会weaken作者: yiner0111 时间: 2012-7-17 10:59
stimulus -- good natured participants：left > right； depression participants: right > left.
choice A -- drug for depression tries to increase the left, by which means the depression ones are right >= left, coincident with the stimulus.
