In a similar study, published in the Journal of Research in Personality, researchers investigated the relationship between signature size and a number of traits, including aggressive and sociable dominance, narcissism, and self-esteem.
发表在《人格研究杂志》上的一项类似的研究中，研究人员调查了签名的大小和个性之间的关系，包括好斗和社会支配倾向，自恋和自尊。

The team analyzed the signatures of 340 Uruguayan university students.
研究小组分析了340名乌拉圭大学生的签名。

This revealed ‘a significant link between signature size and sociable dominance, both for males and females, while narcissism was only in females significantly associated with signature size.’
研究显示了签名大小和社会支配倾向之间的显著联系（不论男女），而自恋只与女性的签名大小显著相关。

People who score higher in sociable dominance often like to be the center of attention, the researchers explained.
研究人员解释说，有社会支配倾向的人通常喜欢成为关注的焦点。

‘Given the positive association of signature size and sociable dominance, larger signatures could be interpreted as a signal of the inclination to stand out and occupy a central position within a group,’ they wrote.
研究人员写道，“考虑到签名大小和社会支配倾向的正相关，更大的签名可以解释为，签名者倾向于在群体中引人注目，成为人们关注的焦点。”

And, signature size isn’t the only indication that a person might be a narcissist.
但签名大小不是暗示一个人自恋与否的唯一标志。

The use of extra lines or exclamation marks could be revealing as well, according to PsyBlog.
心理博客说道，使用额外的划线或感叹号也可以揭示自恋倾向。

‘We’ve looked for that silver lining, and we haven’t found it,’ Dr Ham said, explaining that many people consider narcissism a ‘good trait’ and often link it to Steve Jobs.
哈姆博士解释说，很多人认为自恋是一个“好的特质”，并且经常把它与史蒂夫•乔布斯联系起来。他说，“我们也在寻找这种可能，然而并没有发现。”

‘We didn’t predict at first that signature size would be related only to the dark elements of narcissism. But that’s what we found.’
“我们一开始并没有想到，签名的大小只会与自恋特质中的阴暗面有关。但这就是我们的研究发现。”
