How a higher pitched voice can make you sound more attractive, and suspicious. Also, war: what is it good for? We investigate the link between warfare and sex. And how do our hormones influence perceptions of art?
Georgia O'Keeffe's "Black Iris III". Rudski showed pictures by O'Keeffe to women when they were in the fertile and non-fertile phases of their menstrual cycle. 31% of fertile women interpreted the pictures as sexual, but only 9% of non-fertile women saw the sexual double-meaning (for the record, O'Keeffe herself always denied her art had sexual connotations. She would say that, though, wouldn't she?).
