I found I'm worried about something,but I just don't know what exactly it is.I 'm just worried,and can't even smile .
So,I find an article here to share all members here.Hope all girls not as worried as me.
Scientists have known that on the whole, females of all ages tend to worry more and have more intense worries than males. Women also tend to perceive more risk in situations and grow more anxious than men.
Now we know why.
Women are more likely than men to believe that past experiences accurately forecast the future, according to two new studies.
The research, involving both 3- to 6-year-olds and adults of both genders, tested the extent to which participants' thought that worry can be caused by thinking that a bad event that happened in the past could happen again in the future. (This skill, in its simplest form, is critical to social understanding as it is important to making decisions and assessing risk.)
For the first study, subjects listened to six stories that featured characters harmed by another person or animal in the story. Many days later, the character felt worried or changed their behavior when confronted with the same wrongdoer who had hurt them before. (For example, if one little boy stole a toy from another, the child might be worried when he saw that boy again and hide the new toy he was playing with.)
The second study was the same, except that the person or animal the character ran across later only looked similar to the one that had harmed them before.
