The researchers wanted to find out if there was a connection between personality traits – like openness, extroversion, and neuroticism – and a person’s profile picture.

研究人员希望找到性格特点（如开放、外向、神经质等）与个人头像之间的关联。

According to the results, open people are more likely to pose in an unusual way and use objects such as glasses or a guitar in their profile photo because they enjoy new and exciting experiences.

结果表明，开朗的人更倾向于在头像中摆出别具一格的姿势，并用上眼镜、吉他等物件，因为这些人喜欢全新刺激的体验。

Meanwhile, neurotic people often hold back their negative emotions. They try to avoid showing their face；instead, they use an image of something like a pet, a car or a building. That’s because neurotic people are strongly influenced by the “strong social norm against a very sad or angry appearance in profile pictures,” Daniel Preoiuc-Pietro from the University of Pennsylvania wrote in the research paper.

与此同时，神经质的人常常掩饰自己的消极情绪。他们试着避免展示自己的面容，而是用宠物、汽车或者建筑物等物的图像来代替。那是因为神经质的人深受“强大的社会规范影响，不喜欢十分悲伤或者愤怒的表情出现在头像当中，”宾夕法尼亚大学的丹尼尔·普里奥克-彼得罗在研究报告中写道。
