Was Jennifer Aniston's character Beth in the film He's Just Not That Into You attracted to her boyfriend Neil, played by Ben Affleck, because of his big pupils?

    Researchers have discovered what women are really thinking when they look into a man’s eyes – and it is all about the size of their...pupils.

    Women become attracted to men with large pupils just as they are approaching their most fertile time of the month, the study at Edinburgh University found.

    Scientists suggest that it may be because it indicates that the man is sexually interested in them and available for mating. Pupil size made no significant difference for the rest of the menstrual cycle.

    In the research, published in respected journal Personality And Individual Differences, photographs of six equally attractive men were presented to a judging panel of ten women.

    But for each man, three versions of the photo were produced, with the pupils large, medium or small.

    The pictures of the men were then mixed up and put into pairs for the women to rate.

    Participants recorded their age, whether they were using hormonal birth control, the date of onset of their menstrual period preceding the test and the length of their menstrual cycle.

    The results revealed that attraction to large pupils shot up four days before day 13 of the menstrual cycle, the usual monthly peak in fertility.

    在影片《其實他沒那么喜歡你》中，Jennifer Aniston飾演的Beth喜歡上她的男朋友Neil，是不是因為其扮演者Ben Affleck也有一雙大眼睛？

    研究人員已發現女人在看男人的眼睛時他們到底在想什么——那主要和他們瞳孔的大小有關。

    愛丁堡大學研究發現，女人開始被大瞳孔男人所吸引就在一個月中她們的卵子最活躍的那段時間。

    科學家提出，那可能是由于在她們眼里，它暗示著男人更性感更易交配。在月經周期其余的日子里，瞳孔大小顯示不出這種明顯差異。

    在發表于權威雜志《個性與個體差異》上的該項研究中，6個具有同等吸引力的男人的照片擺在由10個女人組成的評判團前。

    但是每個男人照片都被改成3組，一組瞳孔大的，一組瞳孔中等大小的，一組瞳孔小的。

    然后這些男人的照片被混合在一起，讓每組2個女人來評價。

    這些參與者的年齡均記錄在案，以及是否使用激素節育，測試前月經期初始日子和月經周期的長短。

    研究結果顯示，大瞳孔的吸引力在通常每月的卵子活躍期也就是月經周期前13天開始，有4天會表現得非常強烈。
