Argument53
Thirteen years ago, researchers studied a group of 25 infants who showed signs of mild distress when exposed to unfamiliar stimuli such as an unusual odor or a tape recording of an unknown voice. They discovered that these infants were more likely than other infants to have been conceived in early autumn, a time when their mothers' production of melatonin-a hormone known to affect some brain functions-would naturally increase in response to decreased daylight. In a follow-up study conducted earlier this year, more than half of these children-now teenagers-who had shown signs of distress identified themselves as shy. Clearly, increased levels of melatonin before birth cause shyness during infancy and this shyness continues into later life.
13年前，研究者研究了一组在受到不熟悉的刺激比如不寻常的气味和未知声音的录音时表现出轻微紧张的25名婴儿。他们发现这些婴儿比其他婴儿更可能在早秋怀孕，而早秋是他们的母亲分泌的melatonin--一种已知会影响一些大脑功能的荷尔蒙--因日照的减少而增加的季节。在今年早些时候所作的跟踪调查中，这些表现出紧张迹象的儿童--现在已经是十几岁--有一半以上认为自己害羞。显然，出生前melatonin的增加导致婴儿期的羞涩并且这种羞涩将延续至生命更晚的阶段。

In this argument, the author concludes that increased levels of melatonin before birth cause shyness during infancy and this shyness continues into later life. To support this claim the author cited the results of a study conducted in thirteen years ago and earlier this year. At first glance, it tempt to agree with the author, but a careful analysis of the study reveals that it accomplishes little toward supporting the author’s claim, as discussed below.

The main problem of the argument involves the cited studys about 25 childrens. It is unreasonable to draw any conclusions about all nations’ infants(or childrens ) based on a study of only 25 infants Denpending on the total number of the infants having birth in early autumn in the nation,it is entirely possible that the 25 infants are not representative of the nation’s infants, generally. For example, perhaps other infants did not show any signs of mild distress when exposed to unfamiliar stimuli. If this is the case, then the result of the study itself lack any merit,let alone any further conclusion based on the follow-up study.
even if mild distress during infancy resulted from increased maleton, it is unfairly to deduce that when the infants grow up into teenagers, they become shy due to increased level of melaton of their mothers, considering that the study contains no evidence to support this assumption. The study only shows more than half these children indentified themselves as shy. What about other children? Of course, they are not shy any longer. So, the reason why these children was shy was, perhaps, resulted from the strictness of his parents, maybe dued to difficulties of lives and maybe account to other possible factors. Without ruling out other possilble reasons for the shyness of these childrens, the author can not convince me that it is the shyness during fancy continues into later life.
Moreover, the argument still has other logical questions, such as the unnecessary cause-and-effect-relationship between the mild distress during infancy and the increased levels of melaton,considering the different length of daylight in the nation. Even if this relationship is established, the author is unreasonable to equal distress with shyness.
In a word, the author provided us a fasle result from an unsubstantiated study. If we regard this conclusion as truth,is it ironically when we see the person born in early autumn is outgoing?
