研究人员调查了在外向性、情绪稳定性、随和性、责任心、自我报告式理解力、智力、想象力和对不同经历的开放性方面的差异。他们分析了有不同的兄弟姐妹搭配、年龄差距和手足人数的家庭。但无论怎么拼接数据,他们都看不到出生顺序和性格特征之间的任何联系。
The study, in Proceedings of the National Academy of Sciences, did find evidence that older children have a slight advantage in IQ scores, but the difference was apparent only in a large sample, with little significance for any individual.
在《美国国家科学院院刊》(Proceedings of the National Academy of Sciences)上刊登的该项研究,确实发现证据表明年龄较大的儿童有轻微的智商优势,但差异只有在大样本才明显,对个人来说意义不大。
The lead author, Julia M. Rohrer, a graduate student at the University of Leipzig, said that birth order can have an effect — if your older brother bullied you, for example.
主要作者、莱比锡大学(University of Leipzig)的研究生朱莉娅·M·罗勒(Julia M. Rohrer)说,出生顺序就可能会有影响,比如你的哥哥可能会欺负你。
“But these effects are highly idiosyncratic,” she said. “There is no such thing as a typical older, middle or younger sibling. It’s important to stop believing that you are the way you are because of birth order.”
