TOPIC: 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.

The seemingly sound argument draw the conclusion that increased levels of melatonin,which known as a hormone naturally increase according to the decreased daylight.To underpinned the conclusion,the arguer cites the investigation results of a group of 25 infants.The argument seems to show some connection between melatonia and the personality of shyness.How ever, based on dubious evidence and ill
ogical reasoning,the argument is far from perfect.

To begin with,the arguer unfairly draw the conclusion implicitly that mild distress is a sign of shyness.However,it is not neccessarily the case.Mild distress may be a natural reaction of all the infants when they are exposed to unfamiliar stimuli,no matter shy or not.The argument don't given the evidence that The other infants would not show signs of mild distress when they are given the same unfamiliar stimuli.Thereby,without detailed evidence about the casual relationship between mild distress and shyness,the assumption of the author is highly suspect.

Moreover,even if the mild distress is indeed a reflection of shyness,it is highly doubtful that melatonin is the right hormone leading to shyness.In early autumn,as not only the daylight decreased but also the temperature decreased,other kinds of hormone may also change in amount.There is a high possibility that may be some other hormones caused the personality of shyness of infants.For example,a kind of hormorn whose amount increased when the temperature decreases may also lead to the personality of shyness.Without evidence to show the exact relationship between melatonin and the personality of shyness.It is vulnerable of the conclusion drawed above.

In addition.The quantity of the 25 infants sample is too small to draw a compellent statistic conclusion.We must also consider the living enviroment where the infants live.There is a high possibility that most of the infants happend to live in unhealthy families which can lead to the formation of shy personality.In order to acquire statistic results as authentic as possible under such a small sample,the researchers should keep a detail record about the process of the infant' growing up.

After careful consideration,the argument lacks sufficient evidence as well as precise reasoning to make a sound argument.The argument can be improved if the arguer provide more detailed evidence to prove that mild distress is one of the behaviors of shyness.The aruger also need to enlarge the capability of the research sample in order to draw a more authentic conclusion.

The seemingly sound argument draw the conclusion that increased levels of melatonin, which known as a hormone naturally increase according to the decreased daylight(increased levels of melatonin 怎么样?句子成分缺少). To underpin the conclusion,the arguer cites the investigation results of a group of 25 infants.The argument seems to show some connection between melatonia and the personality of shyness. However, based on dubious evidence and illproblematic logical reasoning, the argument is far from perfect.

To begin with,the arguer unfairly draw the conclusion implicitly that mild distress is a sign of shyness. However,it is not neccessarily the case. Mild distress may be a natural reaction of all the infants when they are exposed to unfamiliar stimuli, no matter shy or not. The argument doesn't given the evidence that The other infants would not show signs of mild distress when they are given the same unfamiliar stimuli.Thereby,without detailed evidence about the casual relationship between mild distress and shyness,the assumption of the author is highly suspected.

Moreover,even if the mild distress is indeed a reflection of shyness,it is highly doubtful that melatonin is the right hormone (melatonin) leading to shyness. In early autumn, as not only the daylight decreased but also the temperature decreased, other kinds of hormone may also change in amount. There is a high possibility that may be some other hormones caused the personality of shyness of infants. For example,a kind of hormorn whose amount increased when the temperature decreases may also lead to the personality of shyness. Without evidence to show the exact relationship between melatonin and the personality of shyness.It is vulnerable of(for) the conclusion drawed above.

In addition.The quantity of the 25 infants sample is too small to draw a compellent(compelling) statistic conclusion.We must also consider the living enviroment where the infants live. There is a high possibility that most of the infants happend to live in unhealthy families which can lead to the formation of shy personality.(应当解释一下为什么high possibility) In order to acquire statistic results as authentic as possible under such a small sample, the researchers should keep a detail record about the process of the infant' growing up.

After careful consideration, the argument lacks sufficient evidence as well as precise reasoning to make a sound argument. The argument can be improved if the arguer provide more detailed evidence to prove that mild distress is one of the behaviors of shyness.
