すいません、これ、何の冗談？

The sample group were college students of both sexes. They were invited one by one to enter a changing room. In the room was either a sweater or a swimsuit. Not both. The student, alone in the room, was asked to try it on and take 10 minutes to evaluate how they looked in the garment. While they did this, they were also asked to complete a maths test. Set that to music.
The study, That Swimsuit Becomes You: Sex Differences in Self-objectification, Restrained Eating and Math Performance, found no differences in the performance of the young men, togs or sans togs. But, as the APA notes, "young women in swimsuits performed significantly worse on the (maths) problems than did those wearing sweaters".

Most girls are crazy about algebra in a changing room

　マジでつか？
　っつーか、この実験を考案した人の発想が素晴らしいと思ってしまうのは私だけ？
　しっかしねー、服装で成績が違うというのは、にわかには信じられないよね。本当なら、入試や資格試験を受ける女性の方々、当日、露出の多い服はひかえようぜ！
