What is a women's perceptive?

So, what's a women's perceptive? According to Why Women Are More Perceptive The Definitive Book of Body Language by Barbara Pease, Allan Pease, "Overall, women are far more perceptive than men, and this has given rise to what is commonly referred to as "women's intuition." Women have an innate ability to pick up and decipher nonverbal signals, as well as having an accurate eye for small details. This is why few husbands can lie to their wives and get away with it and why, conversely, most women can pull the wool over a man's eyes without his realizing it.
Research by psychologists at Harvard University showed how women are far more alert to body language than men. They showed short films, with the sound turned off, of a man and woman communicating, and the participants were asked to decode what was happening by reading the couple's expressions. The research showed that women read the situation accurately 87 percent of the time, while the men scored only 42 percent accuracy. Men in "nurturing" occupations, such as artistic types, acting, and nursing, did nearly as well as the women; gay men also scored well. Female intuition is particularly evident in women who have raised children. For the first few years, the mother relies almost solely on the nonverbal channel to communicate with the child and this is why women are often more perceptive negotiators than men, because they practice reading signals early."
