53Thirteen 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.



抱歉，今天上课，只来得及列提纲了。

1、论据瑕疵：
小样本：25 infants

特殊样本：who showed signs of mild distress when exposed to。。
2、因果关系（小，例子内部）：melatonin会影响某些脑细胞，但不一定导致婴儿对怪异气味、不熟悉声音过于敏感。
3、因果（大）：即使M会使婴儿对怪异气味、不熟悉声音过于敏感,也未必会导致孩子们内向甚至延续到后来的人生。
